MAX195BMDE - 16-Bit 85ksps SAR ADC | Analog Devices (Maxim)
The Analog Devices (formerly Maxim Integrated) MAX195BMDE is a 16-bit, 85 ksps successive-approximation analog-to-digital converter (ADC) that combines high accuracy, low power consumption, and a 10 µA shutdown mode, housed in a 16-pin ceramic DIP (JEDEC MS-160C) package. The military temperature grade (-55 °C to +125 °C) suffix 'BMDE' designates the through-hole DIP variant qualified for harsh-environment systems. A successive-approximation ADC (SAR ADC) is a type of data converter that resolves a single analog sample per conversion cycle by performing a binary search against an internal precision DAC and comparator. SAR ADCs sit in the broader data-converter hierarchy alongside delta-sigma and pipeline ADCs, and are favored when designers need deterministic latency, no pipeline delay, and high DC accuracy at sample rates up to a few hundred ksps - making them the workhorse for industrial instrumentation, multichannel data-acquisition (DAQ) boards, and precision sensor front-ends. Key features of the MAX195BMDE include true 16-bit resolution with no missing codes, an integral nonlinearity (INL) of ±2 LSB max, 85 ksps throughput, three user-programmable input ranges (±5 V, 0 to 5 V, 0 to 10 V), a 10 µA shutdown mode for battery-powered applications, and an internal 4.096V reference. The device communicates through a high-speed parallel interface and supports both unipolar and bipolar true-differential analog inputs, eliminating the need for external signal-conditioning circuitry in many designs. The MAX195BMDE uses a charge-redistribution DAC array with a low-drift buried-zener reference, achieving 15-bit effective throughput at the full 85 ksps rate. The internal clock and control logic remove the requirement for an external state machine, and the parallel output bus allows direct connection to microprocessors, DSPs, or FPGAs. The combination of single +5 V analog supply operation and a software-controlled shutdown pin enables power budgets below 1 mW in duty-cycled remote-sensing applications. Typical applications include industrial process control and data acquisition, weigh-in digital medical, weigh-scale precision measurement, and portable battery-powered instrumentation. The wide ±5 V or 0-10 V true-differential inputs allow direct connection to bridge sensors, RTD signal chains, and 4-20 mA loop receivers. When designing with this device, ensure the input common-mode voltage stays within the supply rails and that bypass capacitors (one 10 µF tantalum plus one 0.1 µF ceramic) are placed within 5 mm of the supply pins. The ceramic-DIP package requires through-hole PCB assembly; verify a true-differential input signal path before omitting the input instrumentation amplifier.

MAX196ACAI - 12-Bit 6Ch DAS, ±10V, 100kSPS, 28-SSOP | Maxim Integrated
The Maxim Integrated MAX196ACAI is a 12-bit, 6-channel, multi-range data-acquisition system (DAS) with 12-bit parallel bus interface, sampling at up to 100 kSPS and housed in a 28-pin SSOP (5.3 mm body width) package. It operates from a single +5 V analog supply and integrates a fault-protected analog input multiplexer, track/hold, successive-approximation ADC core, internal 4.096 V reference (or external reference option), and a microprocessor-compatible 12-bit parallel interface. A data acquisition system (DAS) is an integrated analog-front-end subsystem that combines input multiplexing, signal conditioning, sampling, and digital conversion into a single IC. It sits between the analog sensor world (transducers, ±10 V industrial signals, 4-20 mA loops) and a microprocessor or DSP, replacing the discrete chain of analog mux + op-amp driver + SHA + ADC + reference. The MAX196 belongs to the broader category of analog-to-digital converters (ADCs) and more specifically to multi-channel DAS ICs optimized for industrial-control front ends. Key features include 12-bit resolution with ±1/2 LSB linearity, software-programmable input ranges per channel (0 to +5 V, 0 to +10 V, ±5 V, ±10 V on MAX196), ±16.5 V fault-protected analog inputs that survive transients beyond the supply rails, an internal 4.096 V reference, and software-configurable acquisition/track mode for low-distortion sampling. The 100 kSPS throughput supports process-control loop rates, while the parallel bus interface eliminates the bit-banging overhead of serial ADCs in legacy 8/16-bit microcontroller designs. Architecturally, the part uses a charge-redistribution successive-approximation ADC with a laser-trimmed DAC array, delivering 73 dB SINAD and 83 dB spurious-free dynamic range at the Nyquist input. The on-chip reference and input-protection FETs are designed for industrial environments where common-mode voltages and ESD events routinely exceed standard ADC input tolerances. Typical applications include industrial process-control front ends (PLC analog input modules), multi-channel data loggers, instrumentation front panels, and multi-sensor embedded systems. Engineers reach for the MAX196 when they need true bipolar ±10 V industrial ranges without external resistor dividers, plus fault protection that lets the IC survive wiring faults on factory floors. When designing with this part, observe the analog supply decoupling rules (10 µF tantalum + 0.1 µF ceramic close to AV+ pin) and place a 0.1 µF bypass on the +5 V logic supply. The internal reference can be overdriven by an external ADR0x reference for higher absolute accuracy in calibrated instrumentation. This page synthesizes distributor pricing, SSOP drop-in alternatives, and practical design notes not found in the manufacturer datasheet, including cross-comparison against MAX196AEAI+ (extended-temperature grade), MAX196ACWI+ (SOIC-28 wide), and pin-compatible multi-channel DAS parts from Analog Devices.
MAX196AEAI - 12-Bit 100kSPS 6-Ch ±10V DAS ADC, SSOP-28 | Maxim
The Maxim Integrated (Analog Devices) MAX196AEAI is a multi-range, 12-bit data-acquisition system (DAS) that integrates a 6-channel analog input multiplexer, track-and-hold amplifier, successive-approximation register (SAR) ADC, and on-chip reference. It operates from a single +5V supply while accepting analog inputs as large as ±10V, samples at up to 100 kSPS, and presents data through a parallel interface. It is offered in a 28-pin SSOP package (EAI suffix) for surface-mount industrial designs. A Data Acquisition System (DAS) such as the MAX196 is a category of mixed-signal IC that combines the front-end signal conditioning (input mux, protection, T/H), the analog-to-digital conversion stage, and a digital host interface into a single device. Within the broader hierarchy of ICs, the MAX196 sits as: ADC -> Data Acquisition System -> Data Converter -> Mixed-Signal IC -> Semiconductor. Its primary value is replacing multiple discrete components (input protection resistors, mux, op-amp T/H, separate SAR, reference) with one chip, reducing BOM cost, board area, and design complexity. Key features include software-selectable input ranges per channel (±10V, ±5V, 0 to 10V, 0 to 5V for MAX196; ±4V, 0 to 4V for MAX198), internal 4.096V reference (with option to overdrive), ±1/2 LSB linearity (A grade), ±16.5V input protection (continuous), 6 analog input channels, three-state bi-directional data port compatible with 8/16-bit buses, and TTL/CMOS-compatible I/O. Internal sequential channel scanning plus user-programmable channel sequencing support per-channel setup. Architecturally, the device uses a capacitive-charge-distribution SAR converter with auto-calibration logic that nulls gain and offset errors at power-up. The on-chip reference is a buried Zener type with 50 ppm/°C typical drift. Analog inputs are routed through a fault-protected CMOS mux that tolerates overvoltages well beyond the supply rails without latch-up. Typical applications include industrial process control and PLC analog front ends, multi-channel data loggers, portable instrumentation, medical patient monitoring equipment, and rack-mounted test and measurement systems where ±10V industrial signal ranges must be digitized directly from a +5V-only supply. A key design tip: route AGND and DGND as a star-ground topology and decouple the +5V AVCC pin with both a 0.1 µF ceramic and a 10 µF tantalum as close to the IC as possible. For ±10V input ranges, use the internal 4.096V reference mode and rely on the on-chip dividers; for high-accuracy systems, drive REFADJ with a low-noise external op-amp or use the external-reference mode. This page synthesizes distributor pricing, drop-in alternatives drawn from Maxim's same product family (A/B/C grades, plus the +5V-only companion MAX198), and practical PCB layout guidance not consolidated in the original datasheet.
MAX196AENI - 12-Bit 6-Ch 100ksps Precision ADC | Maxim Integrated
The Maxim Integrated (now Analog Devices) MAX196AENI is a multi-range, single +5V, 12-bit data-acquisition system (DAS) with 12-bit bus interface, sampling at 100 ksps across 6 analog input channels and housed in a 28-pin PDIP (N) through-hole package. Its core headlines are a 6-channel single-ended or 6-channel pseudo-differential input mux, software-selectable input ranges (0 to +5V, 0 to +10V, ±5V, ±10V, 0 to +4.18V) and a successive-approximation ADC with 100 ksps throughput. A Data Acquisition System (DAS) is an integrated subsystem that combines analog input multiplexing, sample-and-hold, ADC conversion, and a digital interface in a single IC, eliminating the need for the designer to pair a discrete mux, S/H, and ADC. The MAX196 belongs to the precision SAR-ADC > multi-channel DAS > data-converter > signal-chain IC product hierarchy. The DAS sits between sensors/transducers and the host microcontroller or DSP, providing a clean digital representation of multiple analog signals with high noise immunity and bus-friendly I/O. Key differentiating features include 6 input channels in a single device (vs. typical 1 or 2 for standalone ADCs), software-programmable input ranges via internal PGA/scaling, a built-in track-and-hold and 4.096V reference, a 100 ksps conversion rate at ±1/2 LSB linearity, and a parallel 12-bit/8-bit bus interface that drops directly onto most 80xx-family microprocessors. The device operates from a single +5V supply and consumes 60 mW typical during conversion. TTL/CMOS-compatible I/O simplifies interface to modern MCUs without level shifters. Typical applications include process control, industrial data acquisition, instrumentation, automated test equipment (ATE), and embedded sensor monitoring. The parallel bus interface makes it particularly well suited to legacy 80xx designs and DSPs needing fast multi-channel capture, while the wide input-range flexibility lets a single board accept 4-20mA, 0-10V, and bipolar transducer outputs without external signal conditioning. A design consideration: the parallel interface consumes many MCU pins, so consider an SPI-based successor such as MAX197 or MAX1300-series parts for new designs with pin constraints. Decouple the supply with a 0.1uF ceramic plus a 10uF tantalum adjacent to the +5V and DGND pins.
MAX197ACAI+T - 12-Bit 100kSPS DAS, 28-SSOP | Analog Devices
The Analog Devices MAX197ACAI+T is a 12-bit, 100kSPS multi-range Data Acquisition System (DAS) requiring only a single +5V supply, packaged in a 28-pin SSOP (5.30mm width). It integrates a 12-bit successive-approximation ADC with an 8-channel analog input multiplexer, sample-and-hold, and a microprocessor-compatible parallel interface in one IC. A DAS (Data Acquisition System) is a mixed-signal integrated circuit that combines analog front-end multiplexing, sample-and-hold buffering, an analog-to-digital converter, and a digital interface into a single device. Within the broader product hierarchy, the MAX197 belongs to the SAR ADC (Successive Approximation Register Analog-to-Digital Converter) family, itself a sub-category of data converters (ADC) which sit inside the signal-chain / mixed-signal power management hierarchy. Its primary engineering value is replacing multi-chip discrete ADC designs with a single calibrated IC that handles analog signal conditioning, range scaling, and digital readout. Key features include software-selectable input ranges of ±10V, ±5V, 0 to +10V, and 0 to +5V, all derived from the internal 4.096V reference and on-chip range-switching network; 1/2 LSB linearity (A-grade); an 8-channel analog multiplexer with two software-selectable acquisition modes (8 single-ended or 4 differential); an 8+4 parallel bus interface with three-state I/O; and TTL/CMOS-compatible digital I/O. Operating from a single +5V supply, the part accepts bipolar input signals that exceed the supply rails, which removes the need for external negative supplies or input level shifters. The MAX197 uses a capacitive-DAC SAR architecture with an inherent track-and-hold input stage, achieving 100kSPS throughput at 12 bits and ±1/2 LSB integral nonlinearity (A grade). An internal 4.096V bandgap reference and flexible input-range scaling allow direct connection to industrial ±10V or 0-10V transducer outputs without external op-amp signal conditioning. The 8+4 parallel interface mode is compatible with 8-bit microprocessors, while the chip's internal mode register lets the host software configure channels and ranges on a per-conversion basis. Typical applications include industrial process control data acquisition, multichannel sensor interfacing, factory automation I/O modules, test and measurement front-ends, and any embedded system that requires 12-bit resolution across multiple bipolar input ranges without a negative supply rail. Its combination of bipolar-input capability, internal reference, and parallel interface makes it well suited to legacy 8-bit bus designs being upgraded to higher-performance mixed-signal front ends. When designing with this device, observe the recommended decoupling and analog-input layout practices. Place a 0.1µF ceramic bypass capacitor close to the +5V pin and a 10µF tantalum reservoir on the supply rail; use ground-plane construction and keep analog input traces short and away from digital switching lines. Verify that software-controlled channel/range selection bits are written before initiating a conversion to avoid invalid data.

MAX197AENI - 12-Bit 100ksps 8-Ch DAS ADC | Maxim Integrated
The Maxim Integrated MAX197AENI is a multi-range, 12-bit data-acquisition system (DAS) requiring only a single +5V supply, yet accepting analog input signals that may span both above the power-supply rail and below ground. Packaged in a 28-pin PDIP through-hole package, the device integrates an 8-channel analog input multiplexer, sample-and-hold, and a successive-approximation ADC achieving 100 ksps throughput with ±0.5 LSB integral nonlinearity in the A-grade variant. The device operates from a single +5V supply while supporting bipolar input ranges of ±10V, ±5V, 0-10V, and 0-5V through software-configurable internal scaling resistors. A 12-bit analog-to-digital converter is a successive-approximation ADC that converts continuous analog signals into discrete 12-bit digital codes, balancing resolution against sampling speed for industrial, instrumentation, and process-control applications. As a member of the data-acquisition IC family, the MAX197 sits in the hierarchy of ADC -> data converter -> signal chain IC -> mixed-signal semiconductor. Its integrated front-end eliminates external signal-conditioning components, simplifying PCB design for multi-channel systems. Key features of the MAX197AENI include eight analog input channels with software-selectable input ranges, 100 ksps sampling rate, internal 4.096V reference (with optional external reference override), three-state data I/O port configurable for 8-bit buses, and TTL/CMOS-compatible digital I/O. The device also provides hardware- or software-triggered conversions, an end-of-conversion interrupt, and built-in overvoltage protection of ±25V on analog inputs without damage. Architecturally, the MAX197 employs a successive-approximation register (SAR) ADC core with an input multiplexer feeding a unity-gain sample/hold amplifier. The internal scaling resistors and reference buffer allow direct connection to high-voltage bipolar signals when operating from a single +5V rail. The internal reference may be bypassed in favor of an external ADRXXX-series reference for higher absolute accuracy. Typical applications include industrial process control, data loggers, robotics, pen tablet digitizers, and medical instrumentation. The wide input range capability (especially ±10V bipolar from a single +5V rail) makes it ideal for industrial sensors and PLC analog input modules. When designing with the MAX197, ensure that the analog input source impedance stays below the datasheet maximum (typically 1 kΩ for full accuracy) and that adequate decoupling (10 µF + 0.1 µF) is placed at AVDD and DVDD. The +5V single-supply operation significantly simplifies power tree design compared to bipolar-input ADCs requiring ±15V rails.

MAX198ACNI - 12-Bit 6-Ch 100ksps ADC | Maxim | Multi-Range
The Maxim Integrated MAX198ACNI is a 6-channel, multi-range, 12-bit data-acquisition system (DAS) with successive-approximation register (SAR) architecture, providing up to 100 ksps sampling rate on a single +5 V supply. Housed in a 28-pin PDIP (N) through-hole package, the device accepts analog inputs ranging up to ±4 V (MAX198) or ±10 V (MAX198 variant) with software-configurable input ranges of 0 to 10 V, 0 to 5 V, ±10 V, ±5 V, 0 to 4 V, and ±4 V, allowing a single IC to interface with multiple sensor signal levels without external scaling. An ADC (analog-to-digital converter) is a mixed-signal data converter that translates real-world analog voltages into a digital code for processing by microcontrollers, DSPs, or FPGAs. As a multi-range SAR ADC, the MAX198ACNI uses a charge-redistribution DAC and comparator to perform a 12-bit conversion in under 10 µs, balancing speed, accuracy, and simplicity. Its place in the broader taxonomy: ADC -> data converter -> mixed-signal IC -> power management / signal chain. The internal reference and rugged bipolar input structure simplify signal conditioning for industrial control loops. Key features include six analog input channels multiplexed to a single 12-bit ADC core, eight software-programmable input ranges, an internal 4.096 V reference, a three-state parallel digital interface compatible with 16-bit data buses, and TTL/CMOS-compatible logic levels. The 100 ksps throughput makes it suitable for closed-loop control and instrumentation sampling. Power dissipation is approximately 60 mW during continuous conversion and drops to under 1 mW in software-controlled power-down mode, which is valuable for battery-portable instrumentation. Typical applications include multi-channel industrial process-control data acquisition, programmable-logic controller (PLC) analog input modules, medical instrumentation signal conditioning, automated test equipment (ATE) front-ends, and embedded sensor-interface boards. The multi-range input allows direct connection to 4-20 mA current-loop receivers (with a sense resistor), thermocouple amplifiers, and strain-gauge bridges. When designing with the MAX198ACNI, bypass VDD and VSS pins with 0.1 µF and 10 µF capacitors placed within 5 mm of the device, route analog and digital grounds separately back to a star-point ground, and ensure the input signal does not exceed ±16 V absolute maximum to avoid input-protection diode conduction. The 'A' grade provides ±0.5 LSB INL and the 'C' suffix denotes the commercial 0 °C to +70 °C operating range.

MAX198ACWI - 6-Channel 12-Bit DAS, 5V, 100kSPS | Maxim/ADI
The Analog Devices (formerly Maxim Integrated) MAX198ACWI is a 6-channel, multi-range, 12-bit Data Acquisition System (DAS) with a 12-bit parallel bus interface, packaged in a 28-pin wide SOIC. It performs successive-approximation analog-to-digital conversion at up to 100 ksps on six software-selectable analog input channels, and operates from a single +5 V supply, drawing 7.5 mA (typ) operating and 1 mA (typ) in power-down mode. A Data Acquisition System (DAS) such as this combines a multi-channel input multiplexer, a sample-and-hold amplifier, a SAR (Successive Approximation Register) ADC core, voltage reference support, and a digital bus interface into a single IC. The MAX198ACWI sits in the ADC IC family, beneath the broader category of data-conversion / data-acquisition semiconductors, and is used as the analog front-end in distributed control, instrumentation, and embedded systems where multiple analog signals must be digitized and delivered to a host CPU or DSP over a fast parallel port. Key features include software-configurable unipolar input ranges of 0 V to +VREF (where VREF is the internal 4.096 V bandgap or an external reference) and 0 V to +5 V, 6.0 us conversion time, an internal 4.096 V reference, and AC + DC (±1/2 LSB) linearity over the operating range. Software-configurable bipolar ranges (±VREF, ±5 V on the MAX196, ±10 V on the MAX197) are the user's choice. The three-state bidirectional data port is compatible with 16-bit data buses, and bus-release timing is matched to the read cycles of most 8051-family, 68HC11, and similar microprocessors. All digital I/O are TTL/CMOS compatible, simplifying level translation in mixed-voltage designs. Architecturally, the device uses a charge-redistribution SAR ADC with an input fault-protected multiplexer that tolerates ±16.5 V overvoltage on any analog input without damage. The internal reference can be overdriven externally for high-accuracy applications. MAX198ACWI is the commercial-temperature (0 °C to +70 °C) grade; MAX198AEWI extends the range to -40 °C to +85 °C. Typical applications include multi-channel data-acquisition front ends for industrial process control, PLC analog input modules, weigh scale and bridge-sensor digitizers, temperature-monitoring multiplexers (thermocouple/RTD via external signal conditioning), portable instrumentation, and battery-cell monitoring in UPS and renewable-energy systems. Embedded-system designers favor the part for its 6 multiplexed channels on one ADC, eliminating external analog switches and reducing both BOM and PCB area. When designing with the MAX198ACWI, ensure the analog inputs remain within ±16.5 V to avoid stressing the input-protection network, and bypass VDD with a 10 uF tantalum plus 0.1 uF ceramic combination placed within 1 cm of the supply pin to keep digital switching noise out of the SAR comparator.

MAX198AEAI - 12-Bit 6-Ch DAS w/ Fault Protection | Maxim Integrated
The Maxim Integrated MAX198AEAI is a 12-bit, 6-channel, multirange data acquisition system (DAS) with parallel interface and built-in fault protection, supplied in a 28-pin SSOP surface-mount package. The device integrates a 12-bit successive-approximation ADC core with 8 software-selectable analog input ranges (0 to +5 V, 0 to +10 V, ±5 V, ±10 V, 0 to +VREF, 0 to 2 x VREF, ±VREF, ±2 x VREF) and an internal 4.096 V bandgap reference, all from a single +5 V supply. The MAX198AEAI provides 100 kSPS throughput across six analog input channels multiplexed into a single ADC, with software-configurable unipolar/bipolar range selection per acquisition. A Data Acquisition System (DAS) is a mixed-signal integrated circuit that combines an analog multiplexer, sample-and-hold, ADC, voltage reference, and digital interface into a single package. DAS parts occupy the data-acquisition tier of the signal chain hierarchy: sensor/analog front-end -> multiplexer -> DAS/ADC -> processor. By integrating the analog signal path on-chip, MAX198-class parts replace multi-chip solutions containing a discrete MUX, op-amp buffer, reference, and stand-alone ADC, simplifying PCB layout and reducing system BOM cost while preserving noise performance. Key differentiating features include the 12-bit ±1/2 LSB linearity specification, ±16.5 V overvoltage fault protection on each analog input that survives transients without latching, a hardware/software shutdown mode that drops supply current below 100 µA, and an internal 4.096 V reference that can also be overdriven by an external source. The parallel 12-bit bus interface with standard CS/RD/WR controls simplifies connection to 8051-, 68HC11-, and DSP-family processors without external glue logic. Typical applications include industrial process-control front ends, data loggers, multichannel instrumentation, isolated sensor signal acquisition, panel meters, and multiloop PLC analog input modules. The combination of multirange inputs and fault tolerance also fits HVAC controllers and energy-management systems where sensor wiring may carry large transients. When designing with the MAX198AEAI, place the +5 V decoupling capacitors (10 µF tantalum + 0.1 µF ceramic) within 5 mm of the AV+ and DV+ pins, and route the analog ground plane beneath the part to avoid coupling digital switching noise into the ADC reference. The internal reference output (REF) requires a 4.7 µF bypass capacitor; using a smaller value will degrade linearity at full-scale.

MAX198AENI - 12-Bit 8-Ch 100ksps ±4.18V DAS | Maxim Integrated
The Maxim Integrated MAX198AENI is a 12-bit, 8-channel data acquisition system (DAS) with a 100 ksps successive-approximation ADC and a 12-bit parallel bus interface, housed in a 28-pin PDIP (300 mil, through-hole DIP) package. It integrates an analog input multiplexer, precision 4.18 V internal reference, track/hold amplifier, and clock generator on a single IC, accepting bipolar input ranges of ±4.18 V with overvoltage protection up to ±16.5 V. The internal reference is factory-trimmed to 4.18 V ±1% with a typical temperature drift of 35 ppm/°C. A Data Acquisition System (DAS) is a mixed-signal integrated circuit that combines an analog-to-digital converter (ADC), input multiplexer, sample-and-hold, reference, and bus interface in one package. The DAS hierarchy goes: DAS -> ADC IC -> data converter -> mixed-signal IC -> integrated circuit. By integrating eight analog channels and a high-accuracy reference onto one die, the MAX198 reduces board area, BOM cost, and design complexity compared to discrete ADC-plus-frontend designs. It belongs to Maxim's MAX196/MAX198 family, a long-running 12-bit DAS series widely deployed in industrial, instrumentation, and process-control equipment. Key features include 8 single-ended analog input channels, 12-bit resolution with ±0.5 LSB (max) relative accuracy, ±4.18 V bipolar input range, and 100 ksps sampling rate. The MAX198AENI supports 2.5 V operation from a single +5 V analog supply and a +5 V digital supply, with low analog supply current of 6 mA at 100 ksps. Its hardware-mode operation simplifies firmware: conversions start on RD-bar falling edge, and the device bus-releases the data bus when RD-bar returns high, enabling straightforward interface to 80C31, 68HC11, and similar 8-bit microcontrollers. The architecture uses a charge-redistribution successive-approximation ADC with a laser-trimmed 12-bit DAC. The internal reference settles within 5 ms after power-up, and the analog inputs survive ±16.5 V overvoltage without damage. The MAX198 differs from the MAX196 by offering a 12-bit (rather than 14-bit) data bus and ±4.18 V input range rather than the 0 to 5 V / ±5 V ranges of related parts. Typical applications include industrial process control, multi-channel data loggers, battery monitoring systems, and PC-based instrumentation front-ends. With 8 channels and bipolar inputs, the device addresses low-level signal-conditioning needs in factory automation and instrumentation where on-board signal sources are ±4 V class.

MAX198BCAI - 12-Bit 6-Ch 100ksps DAS ADC | Maxim Integrated
The Maxim Integrated MAX198BCAI (now supplied by Analog Devices / Maxim Integrated) is a 6-channel, multi-range, single +5V, 12-bit Data Acquisition System (DAS) ADC with 12-bit parallel bus interface and fault-protected analog inputs, housed in a 28-pin SSOP package. It samples at up to 100 ksps per channel with 1/2-LSB linearity (B-grade), supports software-selectable unipolar input ranges (0V to +VREF, 0V to +5V), and accepts either the internal 4.096V reference or an external reference. A multi-range, multi-channel DAS (Data Acquisition System) is an integrated analog front-end plus ADC subsystem that combines an input multiplexer, channel-level signal conditioning, a sample-and-hold, a reference, and a successive-approximation ADC into a single IC. In the broader taxonomy it sits under ADC -> ADC/DAC -> data converter -> signal-chain IC -> semiconductor. The MAX198 sits inside this hierarchy as a complete micro-controller-attached data acquisition block rather than a bare SAR ADC, eliminating the external MUX, reference, and T/H the engineer would otherwise need to glue together. Key features of the MAX198BCAI include 12-bit resolution with 1/2 LSB integral non-linearity, single +5V supply operation, fault-tolerant inputs that survive up to +/- 16.5V without damage, an internal 4.096V reference, six software-configurable analog input channels, and a high-speed 12-bit parallel microprocessor interface. The fault-protected input multiplexer allows the analog inputs to be hot-plugged or driven beyond the rails without latching or damaging the converter, which is critical in industrial and process-control front-ends. Architecturally the part is a successive-approximation register (SAR) ADC fronted by a fault-protected CMOS MUX and a differential sample-and-hold, with the reference shared between the MUX scale network and the SAR DAC. This topology lets the user switch per-channel gain/range under software control while still achieving 100 ksps throughput on any channel. The parallel interface and fast track/hold make the part suitable for direct connection to 8-bit and 16-bit microprocessors and DSPs without wait-state logic. Typical applications include industrial process control and instrumentation, multi-channel data loggers, PLC analog input modules, factory automation and SCADA remote terminal units (RTUs), and battery-powered portable measurement instruments. Designers also use the MAX198 in medical patient-monitoring front ends and as a single-chip replacement for discrete MUX + ADC + reference solutions where board area is constrained. When designing with the MAX198BCAI, place a 10 uF (minimum) and a 0.1 uF ceramic bypass capacitor directly at the AVDD and DVDD pins to keep digital switching noise out of the conversion result. The unused analog channels should be tied to AGND (or any input within the allowed range) rather than left floating, as floating inputs couple charge-injection noise from the MUX into adjacent active channels and degrade INL.
MAX198BENI - 12-Bit 100kSPS 6-Ch DAS 28-PDIP | Maxim Integrated
The Maxim Integrated (Analog Devices) MAX198BENI is a 12-bit, 6-channel, multi-range data acquisition system (DAS) with fault-protected inputs and a parallel microprocessor interface, housed in a 28-pin PDIP through-hole package. Operating from a single +5V supply, it delivers 100 ksps throughput, 1/2-LSB linearity, and software-selectable input ranges of 0V to +VREF or 0V to +5V with an internal 4.096V or external reference. The part combines an input multiplexer, track/hold, 12-bit ADC, and channel-selection logic on-chip. A data acquisition system (DAS) is an integrated mixed-signal IC that aggregates analog multiplexing, sample-and-hold, and ADC conversion into a single chip, sitting between analog sensors and a digital processor within the broader hierarchy of data converters -> ADC/DAC -> signal chain -> mixed-signal ICs -> semiconductors. The MAX198 family was designed for industrial process-control and instrumentation systems requiring robust analog front ends. Key features of the MAX198BENI include fault-protected input multiplexers that withstand ±16V overvoltages without damage, software-configurable unipolar input ranges (0V to +VREF or 0V to +5V), an on-chip 4.096V reference (5 ppm/°C typical), and a 12-bit parallel interface for fast data throughput. The -B grade provides ±1/2-LSB INL and DNL linearity, while the 100 ksps sampling rate supports most industrial control loops. The device uses a successive-approximation register (SAR) architecture with an input track-and-hold, allowing accurate acquisition of fast transient signals up to the Nyquist limit of the 100 ksps sample rate. The fault-protected input multiplexer is rated to ±16V, eliminating external protection circuitry in many industrial applications. Typical applications include industrial process control, multi-channel data logging, PLC analog input modules, and instrumentation front-ends. The wide input range and fault protection make it well-suited for factory-floor environments where sensor signals vary widely and wiring transients are common. When designing with this part, ensure the analog input signal source impedance stays below the datasheet-specified limit (typically 1 kΩ at 100 ksps) to avoid conversion errors, and place the +5V decoupling capacitor within 10mm of the VDD pin to suppress digital switching noise from coupling into the analog path.

MAX198BEWI - 12-Bit 100kSPS Multirange DAS | Maxim Integrated
The Maxim Integrated MAX198BEWI is a multirange, single +5V, 12-bit data-acquisition system (DAS) with 6 analog input channels and an 8-channel successive-approximation ADC architecture. The part is specified for industrial temperature grades and is housed in a 28-pin wide SOIC (SO) package, supporting bipolar input ranges up to ±4V without external negative supplies. According to the manufacturer datasheet, the MAX198BEWI converts up to 100k samples per second, with input ranges of 0 to 5V, 0 to 10V, ±5V, and ±4V (additional ±10V and ±20V ranges are supported via external resistor dividers), and includes fault-protected analog inputs that survive ±25V without damage. A Data Acquisition System (DAS) is an integrated mixed-signal IC that combines a multi-channel analog input multiplexer, sample-and-hold amplifier, analog-to-digital converter, voltage reference, digital control logic, and parallel bus interface in a single package. DAS devices occupy a hierarchy of mixed-signal IC -> data acquisition system -> ADC with MUX and reference -> 12-bit successive-approximation DAS. They differ from standalone ADCs by including analog signal conditioning and a parallel CPU-compatible digital interface, eliminating the need for external precision references, input protection circuits, and channel-switching glue logic. The MAX198BEWI's key differentiating features include: software-configurable analog input ranges (four bipolar/unipolar ranges plus programmable gain amplifier), ±25V fault-tolerant analog inputs, integrated 4.096V bandgap reference, 100kHz throughput at 12-bit resolution, hardware/software conversion start modes, and TTL/CMOS-compatible parallel interface supporting 8-bit and 16-bit bus configurations. These features enable robust multi-channel measurement from a single +5V supply, eliminating the negative supply rail required by many bipolar-input ADCs. Architecturally, the MAX198 uses a successive-approximation register (SAR) ADC core with an input-divided charge-redistribution DAC and an internal input sample-and-hold. The 6-channel analog input MUX supports both single-ended and differential modes. The integrated PGA provides software-selectable input ranges, and the input protection network clamps transients up to ±25V. An internal 4.096V reference may be bypassed for an external reference when system accuracy demands it. Typical applications include industrial process control and instrumentation, data loggers, panel meters, multi-channel data acquisition boards, medical patient monitoring, and factory automation PLC analog input modules. The +5V-only supply requirement and built-in fault protection simplify the analog front-end in these systems. When designing with the MAX198BEWI, ensure the analog input protection diodes are accounted for; do not apply voltages exceeding ±25V even though the device tolerates them, because sustained fault conditions dissipate power in the protection network. Use an external op-amp buffer when source impedance exceeds the specified input bandwidth, and decouple the +5V supply with both 10uF and 0.1uF capacitors placed close to the AVDD pin.

MAX199ACAI - 12-Bit 8-CH Multi-Range DAS, 28-SSOP | Maxim
The Analog Devices / Maxim Integrated MAX199ACAI is a 12-bit, 8-channel, multi-range data-acquisition system (DAS) with 8+4 parallel bus interface, fault-protected inputs, and a 100 ksps sampling rate, housed in a 28-pin SSOP package. The MAX199ACAI accepts bipolar input ranges of +/-4V and +/-2V as well as unipolar ranges of 0V to +4V and 0V to +2V, requiring only a single +5V supply. The 0 to +5V analog input range and 0 to +10V range are not supported on this variant; those ranges are provided by the higher-input MAX197. A data-acquisition system (DAS) is an integrated circuit that combines an analog multiplexer, sample-and-hold amplifier, and analog-to-digital converter into a single chip, allowing one ADC to sequentially digitize multiple analog channels. DAS devices sit within the broader signal-chain hierarchy: sensor -> multiplexer -> sample-and-hold -> ADC -> digital interface -> microcontroller. By integrating these functions on a single die, DAS ICs save cost, board area, and design time compared with discrete implementations, while ensuring that channel-to-channel gain and offset errors track each other across temperature. Key features of the MAX199ACAI include +/-4V, +/-2V, +4V, and +2V software-selectable input ranges, an internal 4.096V reference, ±16.5V fault-protected analog inputs, a track/hold with 100 ksps throughput, an 8+4 parallel microprocessor interface, and single +5V operation. Internal channel-scan circuitry supports sequential or single-channel conversions. Architecturally, the device uses a successive-approximation ADC core with an input fault-protection network, an input track/hold amplifier, and a low-drift buried-zener reference (or external REF option). The input protection clamps transients up to ±16.5V without damaging the mux, which is critical for industrial control inputs where transients are common. Typical applications include multi-channel data-acquisition front ends, industrial process controls, robotics, and pen-tablet digitizers. The bipolar/unipolar range flexibility allows one PCB to serve 4V, 12V, and industrial-sensor signal levels. When designing with this part, place a 0.1µF ceramic bypass close to VDD and a 4.7µF tantalum bulk cap on the analog supply. The internal reference requires a 4.7µF bypass; using a smaller value increases noise and worsens INL. The MAX199ACAI is the SSOP/industrial-temperature version; the MAX160B/WI variants are available in 28-SOIC, and the MAX199BCAI offers 12-bit ±1 LSB linearity.
MAX199ACNI - 12-Bit 100ksps 8-Ch DAS | Maxim Integrated
The Maxim Integrated MAX199ACNI is a multi-range, 12-bit data-acquisition system (DAS) that operates from a single +5V supply, delivers up to 100 ksps throughput, and integrates an 8-channel analog input multiplexer with software-configurable input ranges of ±4V, ±2V, +4V, and +2V. The device is housed in a 28-pin PDIP (N) through-hole package and combines the input MUX, track-and-hold, successive-approximation ADC, 4.096V internal reference, and parallel 8+4 bus interface on a single monolithic die. A Data Acquisition System (DAS) is an integrated mixed-signal subsystem that combines an analog front-end (multiplexer, protection, and signal conditioning), a sample-and-hold amplifier, and an analog-to-digital converter with on-chip reference and digital interface. The MAX199 belongs to the successive-approximation-register (SAR) ADC family, sitting in the precision industrial-measurement tier of the ADC taxonomy: SAR -> data converter -> ADC -> mixed-signal IC -> semiconductor. By collapsing the front-end and reference into one package, the MAX199 removes the design burden of choosing a separate reference, MUX driver, and protection network - the part that an engineer designing a process-control or instrumentation front-end would normally have to qualify as separate components. Key features include ±16.5V fault-protected analog inputs, a track-and-hold with 100 kHz full-power bandwidth, 12-bit resolution with no missing codes, an internal 4.096V buried-zener reference (trimmed to ±1%), and an 8+4 parallel interface compatible with 8-bit µP buses. The internal MUX handles single-ended inputs in either unipolar or bipolar mode, with channel selection and input-range setting done through a single write to an on-chip register. Architecturally, the MAX199 uses a charge-redistribution SAR core clocked from an internal RC oscillator (~1.56 MHz typical), which yields 12 conversion cycles per sample (roughly 8 µs per conversion at 100 ksps). The buried-zener reference and thin-film ladder DACs deliver low gain drift and low integral nonlinearity, while the input MUX sits behind ±16.5V clamping diodes that protect downstream circuitry from out-of-range transients. Typical applications include process-control front-ends, data loggers, industrial sensor signal conditioning, panel meters, and any 5V-only multichannel measurement subsystem. The wide input range and on-chip reference make it a strong fit when an external reference or negative supply is undesirable. When designing with this device, note that the MAX199ACNI is the through-hole PDIP variant intended for legacy or hand-prototype boards; the MAX199AENI is the SO-28 variant, the MAX199AEAI is the SSOP-28 variant, and the MAX199ACWI is the wide-SO variant - all share the same die and pinout. Decouple VDD with a 0.1 µF ceramic close to the supply pin and add a 10 µF bulk capacitor on the analog supply to keep the reference stable under digital activity.

MAX199AENI - 12-Bit 8-Ch DAS, +5V, Multi-Range ADC | Maxim
The Maxim Integrated MAX199AENI is a 12-bit, 8-channel, multi-range data-acquisition system (DAS) that operates from a single +5V supply and delivers up to 100 ksps conversion throughput, housed in a 28-pin PDIP package. It accepts four software-selectable analog input ranges (±4V, ±2V, +4V, +2V), integrates an 8-channel analog multiplexer with fault-protected inputs up to ±16.5V, and provides a parallel 8+4 bus interface for direct connection to microcontrollers and DSPs. Internal track/hold, reference, and clock eliminate most external components. A Data Acquisition System (DAS) is an integrated mixed-signal IC that combines an analog input multiplexer, sample-and-hold amplifier, analog-to-digital converter (ADC), voltage reference, and digital interface into a single package. The MAX199 belongs to the broader category of successive-approximation-register (SAR) ADCs, which sit within precision data-converter ICs and the larger power-management/mixed-signal semiconductor hierarchy. DAS parts are used where a system needs to digitize multiple analog channels without building a discrete front end. Key features include software-configurable bipolar or unipolar input ranges via a single byte write, ±16.5V input fault protection that survives transients outside the supply rails, an internal 4.096V precision reference with ±0.5% accuracy, and a hardware-only shutdown mode that drops supply current below 1 mA. The internal MUX settles within 1.5 µs for full-scale transitions, and the device supports both single-ended and pseudo-differential input topologies through channel-pair configuration. Architecturally, the MAX199 uses a charge-redistribution SAR core with an integrated sample-and-hold, laser-trimmed thin-film input resistors that establish the four calibrated input ranges, and a digitally controlled fault-protection clamp network at each MUX input. Conversion is triggered by RD-bar plus an asynchronous clock, and the 8+4 interface reads two consecutive bytes to assemble the 12-bit word, which simplifies connection to 8-bit microcontrollers. Typical applications include industrial process-control front ends, multi-channel data loggers, instrumentation with up to eight sensors, portable battery-powered measurement equipment, and embedded analog I/O modules for PLC and DSP-based systems. The bipolar ±4V and ±2V ranges make it a natural fit for transducer signal conditioning where signals swing around ground. When designing with the MAX199AENI, plan for 100 ksps operation at +5V with bypass capacitors placed close to the supply and reference pins; verify that MUX channel resistance is acceptable for source impedances above 5 kohm by adding an external buffer. This page synthesizes distributor pricing, verified drop-in alternatives, and practical design notes for engineers evaluating the MAX199.
MAX199BEAI - 12-Bit 8-Channel +5V Multi-Range DAS | Maxim Integrated
The Maxim Integrated MAX199BEAI is a 12-bit, 8-channel, multi-range data-acquisition system (DAS) that operates from a single +5V supply. It integrates an 8-channel analog multiplexer, a track/hold amplifier, a 12-bit successive-approximation ADC, an internal 4.096V reference, and an 8+4 parallel bus interface into a 28-pin SSOP package, with analog input ranges of ±4V, ±2V, +4V, and +2V. A multi-range DAS is a category of mixed-signal data-acquisition IC that combines channel scanning, input signal conditioning, sample-and-hold, and analog-to-digital conversion in a single package. The hierarchy is: DAS -> mixed-signal IC -> data converter -> analog frontend. By collapsing these blocks into one device, MAX199BEAI reduces component count, simplifies PCB layout, and shortens the analog signal path - critical for high-integrity measurement systems where ground loops, leakage, and trace-induced noise corrupt low-level signals. Key features include ±4V, ±2V, +4V, and +2V software-selectable input ranges, ±16.5V overvoltage fault protection on each analog input, an internal 4.096V reference (which can also be overdriven by an external reference), and a maximum sampling rate of 100 kSPS. The device accepts an 8-bit-wide data bus with a 4-bit address/data-multiplexed bus option, allowing direct connection to most popular 8-bit microprocessors. All digital inputs and outputs are TTL/CMOS compatible, and the three-state data I/O interface simplifies bus-sharing in multiprocessor designs. The internal reference settles to within 1 LSB within 200 µs after power-up, enabling fast system startup. Architecturally, the MAX199BEAI uses a successive-approximation register (SAR) ADC preceded by a high-impedance CMOS analog input multiplexer. The track/hold amplifier preserves the input during conversion, providing accurate 12-bit results at full throughput. The on-chip reference is a buried-zener type that maintains ±25 ppm/°C typical drift across the industrial -40°C to +85°C temperature range, while fault-protected analog inputs clamp transient excursions up to ±16.5V without damage. Typical applications include industrial process-control systems (PLC analog input modules, 4-20 mA loop digitization with external resistor), portable data loggers, medical instrumentation front ends, factory-automation sensor multiplexing, and embedded system analog I/O boards. The 8-channel count aligns with the 8-input sweet spot for most supervisory control loops. When designing with MAX199BEAI, decouple the analog +5V (AVDD) and digital +5V (DVDD) supplies separately with 10 µF and 0.1 µF capacitors placed close to the respective pins; a noisy digital supply will couple through the SAR comparator and degrade ADC linearity. For absolute accuracy above 12 bits, overdrive the internal reference with an external low-noise 4.096V source. Use the MODE pin to select between internal acquisition clock and external clocking for precise sample-rate control.

MAX22530AWE+ - Isolated 12-bit 4-Ch SAR ADC | Analog Devices
The Analog Devices MAX22530AWE+ is a galvanically isolated, 4-channel, multiplexed, 12-bit successive-approximation-register (SAR) analog-to-digital converter (ADC) housed in a 16-pin wide-body SOIC (WSOIC) package. According to the MAX22530 datasheet, it integrates an isolated DC-DC converter that powers all field-side circuitry, allowing field-side measurements to be taken with no external power supply. The device samples at up to 22 ksps and exposes a serial (SPI-compatible) digital interface on the logic side. A SAR ADC is a successive-approximation-register analog-to-digital converter, a class of precision ADC that uses a binary-search algorithm and a precision DAC to convert an input voltage to a digital code in a fixed number of clock cycles. Isolated ADCs sit within the broader signal-chain hierarchy of data-acquisition front ends -> ADCs -> precision converters -> mixed-signal ICs -> semiconductors, where galvanic isolation adds a critical safety barrier between hazardous field voltages and the host processor. Key features include 12-bit resolution, four single-ended input channels multiplexed to one SAR core, integrated digital isolation, an integrated isolated DC-DC converter on chip, and a logic-side supply range of 1.71 V to 5.5 V. The wide-body SOIC package provides the reinforced clearance/creepage required for reinforced isolation. The MAXSafe™ architecture is designed for industrial sensors, PLC analog input modules, and any system that requires isolation between the analog front end and a low-voltage digital controller. Typical applications include isolated voltage and current sensing in motor drives, solar inverters, and industrial process-control loops; PLC analog input modules; battery-management systems; and medical equipment where patient isolation is mandatory. The internal DC-DC converter eliminates the bulky external isolated supply, shrinking the BOM. When designing with the MAX22530, pay attention to the input-channel MUX settling time and the recommended input RC anti-alias filter. Place decoupling capacitors close to both field-side and logic-side supply pins, and observe the wide-body SOIC PCB clearance rules for the rated isolation voltage.
MAX71071+ - 24-Bit Dual-Channel Isolated Metrology ADC | Maxim Integrated
The Maxim Integrated MAX71071+ (now under Analog Devices) is a 24-bit, dual-channel, isolated analog-to-digital converter (ADC) designed for high-precision metrology applications. Housed in a 10-pin uMAX/uSOP surface-mount package, the device pairs with a compatible MAX71xxx host to provide simultaneous current and voltage measurements. The host supplies control, command, and isolated power, while a pulse transformer provides the isolated data and clock path between the device and host, eliminating the need for additional optocouplers or digital isolators in the measurement subsystem. A metrology ADC is a high-resolution data converter optimized for energy metering, power-quality monitoring, and revenue-grade instrumentation. Compared with general-purpose ADCs, metrology converters emphasize DC accuracy, wide dynamic range, low noise, and excellent linearity over industrial temperature ranges. The MAX71071+ sits in the converter hierarchy as: ADC -> data converter -> signal chain IC -> analog/mixed-signal semiconductor. Key features include 24-bit resolution across two input channels, an integrated isolated interface through the host pulse transformer, simultaneous sampling of voltage and current channels, and a small 10-pin uSOP/uMAX footprint suitable for compact, isolated current-sensing modules. The device supports industrial temperature grades and is targeted at smart-meter, sub-metering, and power-monitoring designs where galvanic isolation and high accuracy are mandatory. The MAX71071+ uses an isolated SPI/dual-wire interface to the host, removing the requirement for external digital isolators. This architecture reduces BOM count, board area, and design complexity for isolated energy-measurement front ends. The companion host MAX71xxx device provides the isolated power rail to the secondary side via the pulse transformer, which also carries the bidirectional data between host and ADC. Typical applications include single-phase and polyphase electricity meters, branch-circuit power monitors, isolated current-sensing modules for industrial equipment, solar inverter string monitors, EV charging-station energy meters, and smart power strips. The integrated isolation simplifies safety compliance for line-voltage measurements. When designing with the MAX71071+, follow the datasheet reference layout for the pulse transformer and keep the secondary-side bypass network within the recommended geometry. A [DATA_NEEDED: full input bandwidth / sample rate] and [DATA_NEEDED: effective number of bits / SINAD] should be confirmed from the datasheet, since the available web snippets did not include complete AC performance numbers. This page synthesizes distributor pricing, package-level specifications, drop-in package alternatives, and design guidance distilled from the Maxim Integrated datasheet - context that is not presented in a single view on any major distributor page.
MCP3001-I/MS - 10-Bit SPI ADC | Microchip Technology
The Microchip Technology MCP3001-I/MS is a 10-bit, single-input successive-approximation-register analog-to-digital converter with a 200 ksample/s sampling rate, SPI serial interface, and 8-pin MSOP package. It is designed for embedded control systems that require a compact, low-power analog measurement input. An analog-to-digital converter is an interface IC that converts a continuously varying voltage into a numeric value for processing by a microcontroller or other digital controller. The MCP3001 belongs to the SAR ADC family and the broader ADC and data-converter hierarchy. Its internal sample-and-hold function, SPI interface, and low-power characteristics support efficient acquisition in temperature sensing, industrial measurement, and general embedded control equipment. Key features include 10-bit resolution, one analog input channel, a 200 ksample/s conversion rate, and compatibility with SPI modes 0,0 and 1,1. The manufacturer documentation identifies maximum DNL and INL of ±1 LSB. The -I grade ordering code denotes Microchip's industrial temperature grade, although the exact numerical temperature limits are not present in the supplied web data and therefore require confirmation from the datasheet before use. The MCP3001 uses a successive-approximation conversion architecture. A conversion is initiated after chip select is asserted, and the ADC samples the selected analog input while communicating successive conversion information over the serial interface. The host processor supplies the command bits, reads the converted result, and controls the sampling sequence. This architecture is appropriate when conversion speed, interface simplicity, and low system cost matter more than the throughput or channel count of a higher-performance ADC. Typical uses include digital thermometers, environmental sensors, process-control instrumentation, battery monitoring, laboratory measurement equipment, and embedded analog front ends. The single SPI-compatible channel also makes the device useful in compact designs where a microcontroller has adequate timer and serial-port resources for chip-select handling and clock generation. When designing a PCB for the MCP3001-I/MS, place the device close to the analog source and route the analog input away from noisy switching nodes and high-current traces. Provide a clean reference voltage, confirm the input range against the chosen supply voltage, and keep the SPI traces short. Review the datasheet for the exact recommended input and reference-decoupling network rather than assuming that generic bypass values are sufficient.
MCP3001-I/P - 10-Bit Single-Channel SPI ADC | Microchip
The Microchip Technology MCP3001-I/P is a 10-bit, single-channel, successive-approximation-register analog-to-digital converter with a 200 ksps sampling rate, supplied in an 8-pin PDIP package. It combines low-power operation with an SPI-compatible serial interface, making it suitable for embedded control systems that require one analog measurement channel. The verified distributor data identifies the device as a 1-input, 1-SAR ADC with an industrial temperature range of -40°C to 85°C. An ADC is an integrated circuit that converts an analog voltage into a digital code for processing by a microcontroller, control system, or data-acquisition unit. The MCP3001 belongs to the successive-approximation-register ADC family, which samples an analog input and compares it with an internal reference through a sequence of successive approximation steps. Its 10-bit resolution provides 1024 digital codes across the selected input range, while the SPI interface transfers the conversion result to a host controller. Key verified characteristics include 10-bit resolution, one analog input, SAR architecture, 200 ksps sampling, SPI data access, and an 8-pin PDIP package. The -40°C to 85°C operating range supports industrial temperature environments, although the provided data does not include detailed electrical limits such as supply voltage, input voltage range, reference voltage, conversion timing, or power consumption. The MCP3001-I/P is therefore best evaluated against the complete manufacturer datasheet before final circuit design. Typical application areas include industrial control panels, temperature and pressure monitoring, embedded sensor interfaces, laboratory measurement systems, and low-channel-count data acquisition. The single SPI interface allows a microcontroller to initiate a conversion and read the resulting code, while the compact PDIP package supports through-hole PCB assembly and prototype development. The primary design consideration is analog-signal conditioning. The input should remain within the device's verified operating limits, and the host firmware must account for the ADC resolution, reference voltage, input range, and sampling timing. This page combines verified distributor specifications, manufacturer positioning, comparison data, and practical integration guidance for engineers evaluating the MCP3001-I/P.
MCP3001-I/SN - 10-Bit 200 kSPS SPI ADC | Microchip
The Microchip Technology MCP3001-I/SN is a 10-bit, single-channel successive-approximation analog-to-digital converter with a 200 kSPS sampling rate, SPI serial interface, and 8-pin SOIC package. It operates from a single 5.5 V supply and includes an on-chip sample-and-hold circuit. An ADC converts an analog voltage into a numeric code for processing by a microcontroller, logic controller, or embedded system. The MCP3001 belongs to the SAR ADC hierarchy: successive approximation compares the sampled input against an internal reference and generates a 10-bit conversion result. Its pseudo-differential single input provides a simple interface for potentiometers, resistive sensors, dividers, and industrial control signals while reducing the component count compared with a multiplexed multi-channel converter. Key features include 10-bit resolution, differential nonlinearity and integral nonlinearity specified at a maximum of ±1 LSB, an on-chip sample-and-hold circuit, and serial communication using SPI-compatible modes 0,0 and 1,1. A single 5.5 V supply simplifies power planning, while the 200 kSPS conversion rate supports rapid sensor acquisition and straightforward embedded sampling loops. The MCP3001 uses a serial interface rather than a parallel data bus, reducing the number of connections required between the converter and host controller. Conversion results are shifted out through the combined clock/data pin, while chip select controls the serial transaction. This architecture suits compact control boards where pin availability, board area, and power consumption are more important than maximum channel count. Typical applications include analog front-end conditioning, potentiometer position sensing, temperature or light sensor monitoring, battery-voltage measurement, and industrial embedded control. The 10-bit result provides 1,024 quantization steps, which is appropriate for many slow-changing control signals but may be insufficient for high-precision instrumentation without additional gain, averaging, or oversampling. When designing around the MCP3001-I/SN, protect the analog input from transients, bypass the analog supply close to the device, and provide a stable reference voltage. Source impedance and acquisition time should be checked against the datasheet because settling errors can degrade the least significant bits. The SPI clock and chip-select timing must also satisfy the serial-interface specifications for reliable conversion completion. This page consolidates distributor availability, verified electrical characteristics, same-footprint alternatives, package and temperature details, and practical PCB guidance for engineers evaluating the MCP3001-I/SN as a drop-in 8-SOIC ADC.
MCP3001-I/ST - 10-Bit SPI ADC | Microchip Technology
The Microchip Technology MCP3001-I/ST is a 10-bit, single-input analog-to-digital converter using a successive approximation register, or SAR, architecture with an SPI-compatible serial interface and an 8-pin TSSOP package. It operates from a 2.7 V supply according to the manufacturer datasheet, making it suitable for embedded control systems that sample one analog voltage. The device combines a 10-bit conversion resolution, one analog input channel, and low-power operation in a compact surface-mount footprint. An ADC is an integrated circuit that converts a continuously varying analog voltage into a digital value for processing, storage, or transmission. The MCP3001 belongs to the SAR ADC family within the broader data-acquisition IC and power-management semiconductor hierarchy. Its SAR architecture repeatedly compares the input against an internally generated reference to determine each bit of the result, providing a straightforward interface for microcontrollers and other digital controllers. The verified product information identifies a 10-bit conversion resolution, one analog input, SAR conversion technology, and an SPI-compatible serial connection. These characteristics make the MCP3001 useful where a controller must monitor a single sensor or control signal without implementing a higher-cost or higher-channel converter. The 8-pin TSSOP package also reduces board area compared with larger analog packages, although the narrow lead pitch requires careful assembly and layout. The MCP3001-I/ST is specified for industrial-temperature product ordering, while the temperature limits and detailed electrical limits require confirmation from the manufacturer datasheet. The device also uses a low-power operating concept, as described by Microchip Technology for embedded-control applications. Exact sampling rate, conversion-time, reference-voltage range, input-voltage range, and current-consumption figures are not included in the supplied verified records and therefore are not inferred here. Typical uses include single-channel potentiometer sensing, industrial control-loop monitoring, battery or power-rail measurement, and analog control inputs for embedded systems. In a typical circuit, the microcontroller selects the conversion by asserting chip select, clocks the converter through SCLK, and reads the result from DOUT. A microcontroller with an SPI master peripheral, such as the ATMEGA328P or STM32F072RBT7TR listed in the site MPN collection, can provide the required clocking and data handling. Designers should treat VREF and supply bypassing as critical high-impedance analog nodes. The analog input should be kept short, away from switching-current paths, and referenced to the same ground structure used by the converter. Before production release, verify the exact pin assignment, reference-voltage limits, input range, acquisition timing, and operating-temperature limits against the manufacturer datasheet rather than relying on generic ADC assumptions. This product record combines verified manufacturer and distributor information with package-aware selection guidance, practical interface notes, and a transparent data-availability assessment. It also identifies the limited drop-in alternatives that could be substantiated from the supplied cross-reference results, avoiding unsupported substitutions based only on similar resolution or interface specifications.
MCP3002-I/MS - 10-Bit Dual-Channel SAR ADC | Microchip
The Microchip Technology MCP3002-I/MS is a 10-bit, dual-channel successive-approximation analog-to-digital converter with a 200 ksample/s sampling rate, a 2.7 V minimum supply, and an SPI serial interface. It is packaged in an 8-pin MSOP measuring approximately 0.118 inch, or 3.00 mm, wide. The converter accepts two analog inputs and can be configured for single-ended or pseudo-differential operation according to the manufacturer product-page information. An ADC, or analog-to-digital converter, is an integrated circuit that converts a continuously varying analog voltage into a numeric code for processing by a microcontroller or other digital controller. Within the signal-chain hierarchy, the MCP3002-I/MS is a data-conversion IC, specifically a SAR ADC with an SPI interface. SAR conversion repeatedly resolves the input voltage through a successive comparison process, making this device suitable for embedded instrumentation that prioritizes low complexity, serial integration, and modest resolution. Key features include 10-bit resolution, a maximum sampling rate of 200 ksample/s, two analog input channels, and a serial peripheral interface. The converter supports single-ended or pseudo-differential analog-input configurations, allowing one differential measurement to be represented as a pair of related input channels. The manufacturer materials also identify a maximum differential nonlinearity of ±1 LSB and a maximum integral nonlinearity of ±1 LSB. Its small MSOP package supports compact embedded-control layouts where component area and PCB routing efficiency are important. The SPI interface connects the ADC to a host microcontroller through serial data, clock, chip-select, and supply-reference connections. A 10-bit result provides 1,024 possible codes, while the two channels allow related analog quantities to be sampled without using two separate converter packages. Designers must still establish suitable analog input conditioning, reference-voltage stability, grounding, and digital-bus signal integrity to obtain repeatable measurements. Typical uses include industrial temperature and pressure monitoring, embedded process-control measurements, low-speed sensor acquisition, and general-purpose control systems. Its 200 ksample/s rate is substantially higher than many slow environmental sensors require, while the 10-bit resolution is appropriate for measurement systems that do not need the resolution of a high-precision sigma-delta or successive-approximation converter with more than 10 bits. A critical design consideration is analog-reference and grounding quality because conversion accuracy depends on the reference voltage and the sampled input being represented reliably. Place decoupling capacitance close to the supply pins, use a low-impedance reference path, and keep analog input routing away from fast SPI clock edges. The verified source excerpts do not provide complete pricing, pin-level descriptions, temperature limits, or absolute accuracy curves, so those values require confirmation in the manufacturer datasheet.
