MAX113CNG+ - 8-Bit 4-Channel 400ksps ADC | Maxim Integrated
The Maxim Integrated MAX113CNG+ is an 8-bit, 4-channel flash analog-to-digital converter capable of 400 ksps conversion throughput, with a stated 1.8 microsecond conversion time, and is housed in a 24-pin PDIP package. It operates from a single +3 V supply and includes a power-down mode with a stated 1 microsecond shutdown current. The MAX113CNG+ combines four analog input channels, parallel microprocessor-compatible output, and an 8-bit resolution in one through-hole package. The half-flash conversion architecture provides a practical choice when a system needs moderate sampling speed and compact 8-bit measurement rather than higher-resolution SAR conversion. Its single 3 V supply also simplifies connection to contemporary 3.3 V digital systems. According to the available manufacturer-datasheet descriptions, the MAX113 and MAX117 family is designed for microprocessor-compatible data acquisition and includes power-down capability. The MAX113CNG+ specifically provides four input channels, while the related MAX117 provides eight channels. Engineers can use the MAX113CNG+ for industrial control, instrumentation, panel interfaces, and other systems where four analog quantities must be sampled with a parallel interface. Its 24-pin PDIP package is easy to prototype and inspect, although the through-hole format is larger than a modern surface-mount ADC package. The device's 8-bit resolution represents 256 quantization levels, making it appropriate for coarse measurement, thresholding, position indication, and supervisory control rather than precision laboratory conversion. Application timing should be based on the specified 400 ksps throughput and the manufacturer's bus-access requirements. Power sequencing and signal-source drive capability must be checked against the full datasheet before production use, because those detailed limits are not present in the supplied source excerpts.
MAX113EAG+TG068 - 8-Bit 400ksps 4-Ch ADC | Maxim
The Maxim Integrated MAX113EAG+TG068 (now part of Analog Devices) is a +3V, 400 ksps, 4-channel, 8-bit analog-to-digital converter (ADC) in a 24-pin SSOP package. It features a 1.8 microsecond conversion time using a half-flash architecture and a 1 microampere power-down mode for battery-sensitive applications. Operating from a single +3V supply, the device provides four single-ended analog input channels with microprocessor-compatible parallel interface. An ADC (Analog-to-Digital Converter) is a data-acquisition integrated circuit that converts continuous analog voltage signals into discrete digital codes. ADCs are a subset of data converters, which also include DACs (digital-to-analog). The half-flash (or sub-ranging flash) architecture used by the MAX113 family combines two flash converters and a DAC to achieve 8-bit resolution with fewer comparators than a pure flash design, reducing power consumption and die area. The MAX113EAG+TG068 belongs to the MAX113 product family alongside the MAX117 8-channel variant. Key features include 400 ksps throughput, 1.8 microsecond conversion time, 1 microampere power-down current, single +3V operation, and four single-ended analog inputs. The MAX113EAG+TG068 ships in tape-and-reel packaging with the +TG068 suffix indicating specific reel and packaging orientation. The 24-pin SSOP provides a compact surface-mount footprint suitable for high-density data-acquisition designs. Typical applications include portable and battery-powered instrumentation, digital signal processing front ends, multiplexing data-acquisition systems, and embedded industrial control. The 1 microampere power-down current makes the device particularly suitable for handheld meters and remote sensor nodes where quiescent draw directly affects battery life. The half-flash architecture delivers 8-bit resolution at sample rates suitable for audio-bandwidth signals and many sensor measurement applications. When designing with this ADC, ensure the analog input signal bandwidth is below the Nyquist limit for the selected sample rate, and add a low-pass anti-aliasing filter ahead of each input. Decouple AVDD with 0.1 microfarad ceramic and 10 microfarad tantalum capacitors placed close to the supply pin to minimize digital switching noise coupling into the analog front end. The power-down pin should be tied to logic-high only during active conversion windows to maximize battery life in portable designs. According to the Maxim datasheet, the +TG068 suffix is a packaging code that does not affect electrical specifications. This page synthesizes distributor pricing, drop-in tape-and-reel and tube equivalents, and practical design notes not found in the manufacturer datasheet, providing a consolidated decision guide for engineers evaluating 8-bit SAR-style half-flash ADCs in the SSOP-24 footprint.
MAX113ENG - 8-Bit 4-Ch 400ksps ADC 1µA Power-Down | Maxim Integrated
The Maxim Integrated MAX113ENG (now ADI) is a microprocessor-compatible 8-bit analog-to-digital converter with 4 single-ended input channels, offered in a 24-pin PDIP through-hole package. It operates from a single +3V supply and uses a half-flash conversion technique to achieve 1.8 µs conversion time (400 ksps throughput), with an active-low PWRDN pin that drops quiescent current to a typical 1 µA for battery-powered designs. What is an 8-bit half-flash ADC? A half-flash ADC is a type of analog-to-digital converter that uses two parallel 4-bit flash stages plus a digital-to-analog converter (DAC) and subtractor to perform an 8-bit conversion in roughly two comparator bank cycles, achieving tens to hundreds of ns per stage. Positioned in the taxonomy: ADC > data converter > signal chain IC > semiconductor, the half-flash architecture is the same family used by the MAX113's companion MAX117 (8-channel variant) and is well suited for embedded microcontrollers, data loggers, and instrumentation front-ends where medium-speed, low-power conversion is required and 12-16 bit precision is not necessary. Key features include a parallel microprocessor interface, single-ended analog inputs with external reference, software-configurable unipolar/bipolar input range, and an analog input bandwidth suitable for audio-bandwidth signals. A hardware power-down pin reduces standby current to 1 µA typical, allowing the ADC to be duty-cycled in battery-powered applications. The 24-pin PDIP package provides easy insertion into through-hole prototypes and educational platforms. The MAX113ENG uses two stacked 4-bit flash ADC sub-blocks plus an internal 4-bit DAC, achieving a total throughput of 400 ksps at 1.8 µs per conversion. The internal track/hold keeps input bandwidth compatible with audio-range multiplexed sources, and the external reference voltage scales the full-scale input range independently of the supply, simplifying ratiometric measurements. Typical applications include portable data loggers, battery-powered instrumentation, digital panel meters, simple DSP front-ends, and embedded 8-bit MCU analog input modules where a true 12-bit ADC is overkill but a discrete CMOS comparator ladder is too slow. Because of its 24-pin DIP form factor and 3V supply, it is a popular choice for hobbyist and educational hardware. Designers should add 100 nF decoupling capacitors directly across the VDD and AGND pins and use the PWRDN pin to manage average supply current in duty-cycled systems. The external reference determines absolute accuracy, so a low-drift, low-noise reference such as the MAX6125 or MAX6190 is recommended for instrumentation-grade measurements. This page synthesizes distributor pricing, drop-in alternatives (MAX113CNG, MAX113CAG, MAX113EAG, MAX113PNG, MAX117), and practical design notes not found in the manufacturer datasheet alone.
MAX1142BCAP+ - 14-Bit 200ksps ADC, +5V, 20-SSOP | Maxim Integrated
The Maxim Integrated MAX1142BCAP+ is a 14-bit, 200 ksps successive-approximation analog-to-digital converter (ADC) with a +5V single supply and an internal +4.096V reference, housed in a 20-pin SSOP package. The device features one single-ended analog input channel and a serial interface compatible with SPI/QSPI/MICROWIRE, eliminating the need for external logic. Its combination of an input scaling network, internal track/hold, on-chip clock, and integrated reference reduces total BOM cost and board area for compact data-acquisition designs. An ADC (analog-to-digital converter) is a semiconductor device that converts continuous analog signals into discrete digital codes for processing by microcontrollers, DSPs, or FPGAs. Successive-approximation-register (SAR) ADCs use a binary-search algorithm with an internal DAC to resolve N bits in N clock cycles, achieving an excellent balance of speed, resolution, and power consumption. Within the broader taxonomy, SAR ADCs sit between flash converters (fastest, lowest resolution) and sigma-delta ADCs (highest resolution, slowest), and they are a key sub-category of mixed-signal data converters used across industrial, instrumentation, and embedded systems. Key specifications of the MAX1142BCAP+ include 200 ksps sampling rate, 14-bit resolution (no missing codes), ±1 LSB INL (B-grade), an internal +4.096V reference, and 1 input channel. Power-supply requirements are +5V single-ended analog supply and +5V digital supply. The integrated +4.096V reference is convenient because 4.096V is exactly 1 mV per LSB, simplifying engineering-unit scaling. The wide input scaling network (via external resistor network) supports input ranges up to ±4A in current-sensing applications. The MAX1142BCAP+ uses a charge-redistribution DAC with a precision bandgap reference, achieving low noise and high DC accuracy. The serial interface uses SPI/QSPI/MICROWIRE protocols, allowing direct connection to most microcontrollers and DSPs. An external reference can override the internal +4.096V reference when higher accuracy or a different full-scale range is required. Typical applications include industrial process control and instrumentation, temperature and pressure monitoring with bridge sensors, current sensing in motor control, battery-powered data loggers, and patient monitoring. The wide input range makes it particularly attractive for ±4A current shunt monitoring and ±10V industrial signal conditioning. When designing with the MAX1142BCAP+, ensure adequate input scaling to match full-scale range, and provide proper decoupling at AVDD and DVDD pins. The internal reference requires a stable supply; for noisy environments, add a 0.1uF ceramic bypass capacitor adjacent to the REF pin to minimize reference-induced conversion noise. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found on the manufacturer datasheet, providing a single reference for engineers evaluating or sourcing the MAX1142BCAP+.
MAX1145BEAP+ - 14-Bit 150ksps 3.3V SAR ADC | Analog Devices
The Analog Devices (formerly Maxim Integrated) MAX1145BEAP+ is a 14-bit, single-input, successive-approximation-register (SAR) analog-to-digital converter with a maximum sampling rate of 150 ksps, operating from a single 3.135 V to 3.465 V supply. Housed in a 20-pin SSOP package with an external reference input, this converter targets low-power precision data-acquisition front ends where a small footprint, simple serial interface, and deterministic latency of a SAR architecture are required. A Successive Approximation Register (SAR) ADC is a class of Nyquist-rate converter that performs a binary search across the analog input range using an internal DAC and comparator, producing one conversion result per N clock cycles. SAR ADCs offer deterministic conversion latency, no pipeline delay, inherently zero-latency single-shot sampling, and excellent DC accuracy. They sit between flash converters (fastest, lowest resolution) and sigma-delta converters (highest resolution, lowest bandwidth) in the data-converter hierarchy. Key specifications of the MAX1145BEAP+ include 14-bit resolution, single-ended analog input, SPI-compatible serial interface, and an external reference. The part is specified over the industrial temperature range and is offered in a 20-pin SSOP. The integrated track/hold and internal oscillator simplify external component count, while the shutdown mode reduces supply current for power-constrained or battery-operated applications. The architecture is built on a charge-redistribution DAC array combined with a precision comparator and SAR control logic. The 3.3 V single-supply operation simplifies power-tree design in 3.3 V digital systems, eliminating the need for level shifters. The wide input bandwidth of the front-end sample-and-hold supports accurate sampling of input signals well beyond the Nyquist frequency when an external antialiasing filter is applied. Typical applications include industrial process-control loops, portable instrumentation, data loggers, and sensor-signal conditioning where a single-ended input feeds a microcontroller or DSP via SPI. The external reference input allows the system designer to choose reference voltage for optimum dynamic range and ratio-metric measurements. When designing with this part, add a 0.1 uF ceramic bypass capacitor as close as possible to the supply pin and ensure the analog and digital ground returns share a single star-ground point. The shutdown pin can be asserted between conversions to reduce power consumption in low-duty-cycle applications. Refer to the manufacturer datasheet for full timing diagrams and reference-circuit recommendations. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers a single decision-ready reference for selecting and sourcing the MAX1145BEAP+.
MAX1147BEUP+T - 14-Bit 4Ch 116ksps 3.3V Precision ADC | Maxim
The Maxim Integrated MAX1147BEUP+T is a low-power, 14-bit, multichannel, successive-approximation analog-to-digital converter (ADC) with an internal track/hold (T/H), internal voltage reference, and internal clock. It provides 4 single-ended or 2 true-differential analog input channels, a 3-wire serial interface, and a maximum sampling rate of 116 ksps. The device operates from a single +2.7V to +3.6V supply, drawing 0.6 mA at 116 ksps. An SAR ADC (Successive Approximation Register Analog-to-Digital Converter) is a type of data converter that uses a binary-search algorithm and an internal DAC to resolve analog inputs. SAR ADCs sit within the broader hierarchy of data converters (ADC -> data converter -> mixed-signal IC -> semiconductor) and are valued for their deterministic latency, low power consumption, and inherent simplicity compared to delta-sigma or pipeline architectures. The MAX1147 family (MAX1146/MAX1147/MAX1148/MAX1149) shares a common 20-pin TSSOP pinout, with supply-voltage and channel-count differences distinguishing the variants. Key features of the MAX1147BEUP+T include ±1 LSB INL and DNL, an internal +2.5V reference (or optional external reference), a hardware-/software-/external-clock shutdown mode that reduces supply current to sub-microampere levels, and an SPI/QSPI/MICROWIRE-compatible serial interface. Its 20-pin TSSOP package, surface-mount gull-wing terminals, and industrial temperature grade (-40C to +85C) suit it for compact, cost-sensitive precision-instrumentation boards. Typical applications include portable data logging, patient monitoring, factory-automation sensor interfaces, pen-digitizer digitizers, and 4–20 mA loop-powered instruments. Designers should consider shutdown-mode current when budgeting battery life, and ensure the analog inputs remain within the supply rails to avoid linearity degradation.
MAX114CAG+ 8-Bit 1MSPS 4-Channel ADC | Analog Devices
The Analog Devices MAX114CAG+ is an 8-bit, 4-channel, 1MSPS flash analog-to-digital converter designed for microprocessor-compatible data acquisition systems. It operates from a single +5V supply, uses a half-flash conversion technique, and is available in a 24-pin SSOP package. The MAX114 family belongs to the flash ADC category within the broader analog-to-digital converter hierarchy. Flash ADCs use an internal parallel array of comparators and decoding logic to convert an analog input into a digital code. Compared with successive-approximation ADCs, the MAX114 architecture provides a stated 660ns conversion time, equivalent to approximately 1MSPS, while retaining an 8-bit resolution suitable for control, monitoring, and legacy parallel-interface systems. Key features of the MAX114CAG+ include four analog input channels, 8-bit resolution, a 1MSPS conversion rate, a microprocessor-compatible parallel output, and an active-low power-down function. The verified manufacturer data states that power-down current consumption is typically 1uA, and that the device returns to normal operating mode in less than 200ns. These characteristics make the converter useful in systems that need rapid sampling but do not require high-resolution or serial-interface conversion. The half-flash architecture is central to the MAX114CAG+ performance. The converter uses parallel internal comparison stages to acquire the input voltage and then resolves the final 8-bit code. This approach is appropriate for applications requiring deterministic acquisition timing and direct connection to a microprocessor data bus. The device is intended for single +5V operation, which simplifies the interface to older 8-bit control systems that already operate from a 5V rail. Typical applications include industrial control and instrumentation, process monitoring, sampled sensor interfaces, embedded measurement systems, and legacy data-acquisition equipment. The four-channel arrangement supports multiple analog inputs without requiring four separate converter packages, while the 1MSPS rate is suitable for control loops and waveform sampling where 8-bit resolution is adequate. Designers should account for the parallel interface and its timing when laying out the PCB. Input, ground, supply, and data-bus traces should be arranged to minimize digital switching noise at the analog inputs. The power-down pin should not be left floating, and the supply bypass strategy should follow the manufacturer datasheet recommendations for reliable operation of this older parallel-interface ADC. This page consolidates the verified MAX114CAG+ specifications, sourcing links, and design considerations with the manufacturer product information. It also distinguishes confirmed parameters from values that require review in the manufacturer datasheet, helping engineers evaluate this 8-bit ADC without confusing it with higher-resolution or serial-interface converters.
MAX114CNG+ - 8-Bit, 4-Channel, 1MSPS ADC | Maxim Integrated
The Maxim Integrated MAX114CNG+ is an 8-bit, 4-channel, 1 MSPS precision analog-to-digital converter with a +5 V supply, single-ended inputs, parallel data interface, and 1 µA power-down current, housed in a 24-pin through-hole DIP package. It combines a multiplexer, sample-and-hold circuit, and flash-type ADC in a single device, allowing four analog inputs to be digitized with one 8-bit converter. An ADC is an analog-to-digital converter, a data-acquisition IC that transforms continuously varying voltage signals into binary values for processing by a microcontroller, computer, or control system. The MAX114 belongs to the data-converter hierarchy, where a multiplexed ADC shares one conversion core among several input channels. Its 1 MSPS conversion rate supports signal monitoring, process measurement, industrial control, instrumentation, and embedded data acquisition. Key features include 8-bit resolution, four single-ended input channels, a 1 MSPS sampling rate, parallel output configuration, flash ADC architecture, a 1:1 multiplexer-to-sample-and-hold ratio, and a +5 V analog supply. Power-down reduces the shutdown current to 1 µA, making the device useful in portable or intermittently operated systems where standby consumption matters. The commercial temperature grade supports general-purpose equipment rather than harsh automotive environments. Internally, the four analog inputs are routed by a multiplexer to a sampling circuit and flash conversion core. Because only one conversion core is used, the input multiplexing structure favors compact cost-sensitive designs over simultaneous-sampling systems. The 8-bit resolution provides 256 digital codes per conversion, so input scaling, grounding, and reference stability directly influence measurement resolution and repeatability. Typical uses include panel-meter and sensor-interface systems, industrial process monitoring, laboratory measurement equipment, battery-powered instruments, and four-channel control systems. The 24-pin DIP package supports prototyping and through-hole assembly but occupies more board area than modern surface-mount packages. Board layouts should route analog inputs away from digital switching nodes and provide a low-impedance return path to the converter ground. When designing around the MAX114CNG+, verify the complete pinout and analog input range in the manufacturer datasheet before layout because the supplied distributor data does not include the full pin mapping. Input conditioning, bypass capacitors, and external reference design remain essential for obtaining useful accuracy from the 8-bit conversion system. Commercial operation should also be checked against the system’s ambient-temperature envelope. This page consolidates verified distributor specifications, lifecycle information, package details, drop-in candidate data, and practical selection guidance. The comparison tables and design notes add engineering context beyond a distributor catalog entry while clearly separating verified facts from parameters that still require datasheet confirmation.

The Maxim Integrated (Analog Devices) MAX1153BEUE+W is a 10-bit, 10-channel (8 external + 2 internal) system-monitor ADC with an internal temperature sensor and VDD monitor, housed in a 16-pin TSSOP package. According to the MAX1153 datasheet family, it provides up to 94 kSPS throughput and accepts single-ended or differential analog inputs through an SPI/QSPI/MICROWIRE-compatible serial interface. The +W suffix indicates RoHS-compliant lead-free construction supplied on tape-and-reel. What is a system-monitor ADC? A system-monitor ADC is a mixed-signal data acquisition IC that combines a multi-channel analog-to-digital converter with on-chip housekeeping functions such as temperature sensing, supply monitoring, and a dedicated input for the analog supply rail. These devices sit at the top of the power-management IC hierarchy and the broader mixed-signal data acquisition family, used in place of standalone ADCs plus separate temperature sensors to reduce BOM count and free up host-controller analog pins. Key features 10-bit resolution (no missing codes), an internal 2.5 V reference, low +4.5 V to +5.5 V single-supply operation, software-configurable unipolar/bipolar input ranges, an internal temperature sensor with ±3 °C accuracy, and a hardware-/software-programmable channel-scan sequencer. The TSSOP-16 package provides a compact footprint suitable for dense system monitor boards. Architecturally, the MAX1153BEUE+W uses a successive-approximation-register (SAR) core with an input multiplexer, sample-and-hold, and reference buffer; the two internal channels continuously digitize the local die temperature and the analog VDD rail, freeing all eight external analog inputs for system voltages such as battery stacks, current-sense amplifiers, thermistor bridges, and transducer outputs. Typical applications include battery-pack monitoring and protection in portable equipment, rack-mounted server and telecom base-station health monitoring, industrial PLC analog front-ends, HVAC controllers, and any multi-rail system requiring on-board temperature telemetry. Because the part combines ADC, temperature, and supply monitoring in one chip, it is widely used to replace three or four discrete components in space-constrained designs. When designing with this part, select input ranges to match the transducer full-scale outputs and ensure the supply decoupling network follows the datasheet recommended capacitor combination. Consider the worst-case cumulative unadjusted error when budgeting system accuracy.

MAX1154AEUE+T - 10-Ch 10-Bit System Monitor ADC | Maxim Integrated
The Maxim Integrated MAX1154AEUE+T is a stand-alone, 10-channel (8 external + 2 internal) 10-bit system-monitor ADC with internal temperature sensor and VDD monitor, housed in a 16-pin TSSOP package. It supports a single-ended analog input range of 0 to VDD and operates from a 2.7V to 5.25V analog supply, consuming only 5 mW (1.7 mA at 3V) at the maximum 94 ksps sampling rate. A system monitor IC (also called a hardware monitor, supervisory ADC, or housekeeping ADC) integrates multi-channel analog-to-digital conversion, temperature sensing, and supply-voltage monitoring into a single chip, reducing external component count versus a discrete ADC plus dedicated temperature sensor design. The MAX1153/MAX1154 family belongs to the Maxim system-monitor hierarchy: SAR ADC -> multi-channel ADC -> system monitor -> supervisory IC -> power management IC. This category of ICs is widely used to monitor processor core voltage, battery stacks, and PCB hot-spots in single-rail systems. Key features of the MAX1154AEUE+T include AutoShutdown (reducing supply current to 190 uA at 2 ksps and to less than 8 uA at 50 sps), an SPI/QSPI/MICROWIRE-compatible serial interface, a dedicated ALERT output for out-of-threshold interrupts, and an on-chip 2.5V reference. Internal channels measure the device's own die temperature and VDD, while the eight external analog inputs accept voltages up to VREF. The architecture combines a 10-bit successive-approximation register (SAR) ADC, a 10-channel analog multiplexer, a bandgap temperature sensor, and an internal reference. AutoShutdown mode and burst-mode sampling enable unattended, low-duty-cycle monitoring that is ideal for battery-powered equipment. The 10-bit resolution provides 0.1% full-scale measurement steps, sufficient for system telemetry but not for high-precision instrumentation. Typical applications include multichannel system monitoring in telecom equipment, temperature and voltage monitoring in industrial controllers, fan-speed and thermal monitoring in servers, battery-cell voltage monitoring in portable devices, and hardware housekeeping functions in embedded designs. The wide 2.7V-5.25V supply range supports both 3.3V and 5V digital rails. When designing with the MAX1154AEUE+T, ensure that the analog input voltage on any external channel stays within 0V to VREF, and place a 0.1 uF decoupling capacitor close to the VDD pin. Configure the ALERT threshold via the SMBus-compatible threshold registers so that the host is notified when any monitored channel exceeds its window.

MAX1156AEUP+ - 14-Bit 135ksps Single-Supply ADC | Maxim Integrated
The Maxim Integrated MAX1156AEUP+ is a 14-bit, 135 ksps, low-power, single-supply successive-approximation analog-to-digital converter (ADC) featuring automatic power-down, a factory-trimmed internal clock, and a bipolar analog input range, housed in a 20-pin TSSOP package. Operating from a single +4.75V to +5.25V analog supply, the device delivers true 14-bit resolution with no missing codes and supports input signals from 0 to +4.096V (unipolar) or ±4.096V (bipolar) when driven through the dedicated bipolar input path. An ADC (analog-to-digital converter) is a data-conversion integrated circuit that samples a continuous-time analog signal and quantizes each sample into a binary code for digital processing. Successive-approximation ADCs (SAR ADCs) use an iterative binary-search algorithm against an internal DAC, achieving a deterministic one-sample-latency conversion well-suited to multiplexed data-acquisition systems, industrial process controls, and instrumentation front-ends. The MAX1156 family belongs to the broader hierarchy: ADC -> data converter -> mixed-signal IC -> signal chain IC -> semiconductor. Its single-supply architecture and bipolar-input option distinguish it from legacy ±12V or ±15V SAR converters. Key features of the MAX1156AEUP+ include 135 ksps throughput, automatic power-down between conversions (reducing supply current to microampere levels at idle), an integrated T/H (track-and-hold) front-end, a parallel digital interface compatible with 3V and 5V logic, and a factory-trimmed internal conversion clock that eliminates the need for an external crystal. The device draws approximately 1.6 mA at full sampling rate and drops to under 10 microamps in power-down mode, making it well suited to battery-powered or energy-conscious data acquisition. Architecturally, the MAX1156 implements a charge-redistribution DAC core with a sample-rate-compensated track-and-hold amplifier that accepts input bandwidths exceeding 1 MHz. The bipolar-input topology scales and level-shifts a differential ±4.096V signal into the ADC's unipolar input range, preserving 14-bit accuracy with INL and DNL both below ±1 LSB. A hardware power-down pin (PWDN) and a software-controllable power-down mode let designers trade off throughput against quiescent current on a per-channel basis. Typical applications of the MAX1156AEUP+ include industrial process control loops, multichannel data-acquisition systems, portable instrumentation, weigh-scale and sensor-signal conditioning front-ends, and motor-control feedback paths. In these deployments the device is usually paired with a precision low-noise LDO regulator on the analog supply rail and a digital isolator if high common-mode voltages are present at the input. When designing the input front-end, ensure the input band-limited signal is below the device's Nyquist frequency relative to the chosen sampling rate, and place a unity-gain buffer between high-impedance sensors and the ADC input to prevent track-and-hold droop. Decouple AVDD with a 10 microfarad tantalum in parallel with a 0.1 microfarat ceramic placed within 5 mm of the supply pin.

MAX1156AEUP+T - 14-Bit 135ksps Bipolar ADC | Maxim Integrated
The Analog Devices (formerly Maxim Integrated) MAX1156AEUP+T is a 14-bit, 135 ksps, low-power, successive-approximation analog-to-digital converter (ADC) with a bipolar analog input range of 0V to 10V (true bipolar) and a single 4.2V supply, housed in a 20-pin TSSOP package. This industrial-temperature ADC delivers ±1 LSB INL (typical) and accepts pseudo-differential inputs with a wide 0V-10V input range, plus automatic power-down to reduce current draw between conversions. The MAX1156AEUP+T integrates a factory-trimmed internal clock, simplifying board layout and reducing BOM cost by eliminating an external oscillator. What is a successive-approximation ADC? A SAR ADC is a sampling converter that uses a binary-search algorithm through an internal DAC to resolve each conversion in N clock cycles, where N is the resolution (14 here). SAR ADCs sit between pipeline and delta-sigma architectures: they offer low latency, deterministic throughput, and zero digital-noise feedback into the input, making them ideal for multiplexed data-acquisition and control loops. Compared with flash ADCs they scale efficiently to higher resolutions; compared with sigma-delta ADCs they skip digital decimation delays. Key specifications include 135 ksps sampling rate, 14-bit resolution, single 4.2V analog supply, 0V-10V bipolar analog input range, automatic power-down between conversions to 0.1 µA, parallel digital interface, and industrial -40°C to +85°C temperature range. The wide bipolar input range is achieved using a true bipolar input stage that handles signals that swing through 0V without requiring a negative supply rail. Architecturally, the MAX1156AEUP+T pairs an input protection/level shifter with a charge-redistribution SAR core, a precision reference (internal or external depending on variant), and a parallel output latch. The 135 ksps throughput, 14-bit resolution, and 0V-10V bipolar input combination target multi-channel data-acquisition front-ends where the input multiplexer can swing through ground. Industrial-grade temperature range and TSSOP-20 footprint ease migration from older bipolar-input ADCs such as the AD7891. Typical applications include process-control analog input modules, industrial PLC data acquisition, factory sensor signal conditioning, medical patient monitoring front-ends, instrumentation panel meters, and multi-channel multiplexed data-acquisition boards. The internal clock and 0V-10V bipolar input range particularly suit mixed-signal industrial backplanes. When laying out this part, place the 10µF bulk bypass and 0.1µF decoupling capacitors as close as possible to the AVDD pin, and keep the digital outputs physically separated from the analog input trace to avoid digital feedthrough into the conversion result. Input RC filtering is recommended when the source impedance exceeds 1 kΩ.

MAX1156BEUP+ - 14-Bit 135ksps Bipolar ADC | Analog Devices
The Analog Devices (formerly Maxim Integrated) MAX1156BEUP+ is a 14-bit, 135ksps, single-supply successive-approximation analog-to-digital converter (SAR ADC) with a bipolar analog input range of 0V to 10V (unipolar) and true bipolar ±5V or ±10V operation, housed in a 20-pin TSSOP package. The MAX1156 is part of the MAX1156/MAX1158/MAX1174 family of low-power ADCs designed for industrial process control, data acquisition, and instrumentation applications requiring precision measurement of high-voltage bipolar signals. A successive-approximation ADC (SAR ADC) is a type of analog-to-digital converter that uses a binary search algorithm through an internal comparator and DAC network to digitize an analog input signal. SAR ADCs offer an excellent balance of speed, resolution, and power consumption: they require no pipeline delay, provide deterministic latency, and typically consume only a few milliwatts of power. Within the broader hierarchy of data converters, the MAX1156 sits in the SAR ADC category, which itself belongs to the data acquisition IC family and ultimately the power management and mixed-signal semiconductor ecosystem. Key features include true bipolar input ranges without external signal-shaping circuitry, 135 ksps sampling rate, integrated 4.096V internal reference (MAX1156), low power consumption of typically 6 mA at 135 ksps, automatic power-down between conversions reducing supply current to 1 µA, hardware-configurable analog input ranges (0 to 5V, 0 to 10V, ±5V, ±10V), and a high-speed SPI/QSPI/MICROWIRE-compatible serial interface. The device operates from a single +5V analog supply and a +3V to +5V digital supply, simplifying peripheral power management design. The MAX1156BEUP+ uses a charge-balancing successive-approximation architecture with an input protection network and a track-and-hold block, allowing the ADC to directly accept industrial-level bipolar voltages that would otherwise require external op-amps. The internal 4.096V reference (MAX1156EUP variant) eliminates the need for an external reference component, reducing BOM cost and PCB area while maintaining ±1 LSB INL and ±1 LSB missing-code performance. Typical applications include industrial process control and PLC analog front ends, data acquisition systems and PC-based measurement cards, medical instrumentation (patient monitoring, blood analysis), and portable or battery-powered instrumentation requiring low quiescent current. The bipolar input range makes the MAX1156 particularly suited for measuring transducer outputs such as strain gauges, load cells, and pressure sensors that natively produce bipolar signals. When designing with the MAX1156, allocate at least 10 nF of bypass capacitance on AVDD and DVDD placed within 5 mm of the package, and reserve PCB space for an optional input RC filter (typically 1 kΩ + 100 pF) to limit broadband noise from the sensor. The MAX1156 is pin-compatible with the MAX1158 (unipolar-only) and MAX1174 (12-bit), enabling a single PCB layout to support different precision/speed grades.
MAX115CAX - 12-Bit 2x4-Channel Simultaneous-Sampling ADC | Maxim
The Maxim Integrated MAX115CAX (now under Analog Devices) is a high-speed, multi-channel, 12-bit data-acquisition system (DAS) with simultaneous track/hold (T/H) amplifiers, packaged in a 36-pin SSOP. It integrates four simultaneous-sampling T/Hs with two multiplexed inputs each (eight single-ended inputs total), a 2us successive-approximation ADC, a +2.5V internal reference, and a buffered reference input that preserves the relative phase information of the sampled signals for powerline monitoring and three-phase motor control. A Data Acquisition System (DAS) is an integrated analog front-end that combines signal conditioning, multiplexing, sample-and-hold, and analog-to-digital conversion on a single IC, sitting hierarchically as: ADC -> data converter -> data acquisition IC -> signal chain -> mixed-signal subsystem. The simultaneous-sampling T/H topology distinguishes DAS from generic ADCs by capturing phase-coherent snapshots across channels at the exact same instant, critical for vector calculations on multi-axis systems where timing skew would corrupt computed magnitudes. Key features include 2us conversion time per channel, throughput up to 390 ksps for one channel, 218 ksps for two, 152 ksps for three, and 116 ksps for all four channels, plus a parallel interface whose access and bus-release timing is compatible with most 16-bit and 32-bit DSPs and microprocessors. Per-channel programmable gain and bipolar input ranges (driven by the +2.5V reference) allow direct interface with ±5V or 0-5V transducers without external signal conditioning. The architecture pairs a successive-approximation register (SAR) ADC core with four dedicated T/H capacitors and dual 4-to-1 input MUXes, sequenced by the on-chip state machine. The internal +2.5V reference (with buffered output for external use) provides ratiometric measurement capability, and the parallel data bus minimizes read latency for closed-loop control loops running on a host processor. Typical applications include three-phase power metering and power-quality monitoring, multi-axis motor control and robotics, vibration analysis and modal testing, and multi-channel data loggers for industrial process instrumentation. The 36-SSOP footprint suits medium-density analog boards where 4-8 simultaneous channels must be acquired without time-skew artifacts. When designing with this device, budget the ORDE active-high enable and power-down mode for sleep current in battery-aware deployments, and decouple AVDD/DVDD with separate 10uF + 0.1uF pairs as close to the pins as possible.

MAX115EAX+ - 12-Bit 8-Input Simultaneous-Sampling ADC | Maxim
The Maxim Integrated MAX115EAX+ is a 12-bit successive-approximation data-acquisition system with eight single-ended inputs, four simultaneous-sampling track-and-hold amplifiers, and a 36-pin SSOP package. Its per-channel conversion time is 2 microseconds, while aggregate throughput is 390 ksps for one channel, 218 ksps for two channels, 152 ksps for three channels, and 116 ksps for four channels. A data-acquisition system, or DAS, combines an analog-to-digital converter with the surrounding signal-conditioning and sampling functions needed to acquire multiple analog inputs. The MAX115EAX+ occupies the ADC/DAC category within integrated circuits and uses four track-and-hold amplifiers so that selected input pairs can be sampled simultaneously. Each of the eight inputs is organized as two four-channel banks, with two multiplexed inputs per amplifier. Key features include 12-bit resolution, four simultaneous-sampling track-and-hold amplifiers, eight single-ended inputs, and 2 microsecond conversion time per channel. The parallel data interface supports direct connection to digital control and acquisition logic. The four-channel aggregate rate of 116 ksps makes the device useful for multichannel measurement systems in which paired signals must be captured close together in time. Technically, the MAX115EAX+ uses a successive-approximation conversion architecture. Its track-and-hold front end captures the selected analog inputs before conversion, preserving the relationship between paired channels during simultaneous sampling. The parallel interface exposes the 12-bit conversion result without requiring a serial protocol. Exact input ranges, supply voltages, reference details, and digital logic levels are identified in the manufacturer datasheet. Typical uses include industrial process monitoring, laboratory data acquisition, instrumentation, vibration analysis, and multichannel sensor acquisition. In a vibration test system, simultaneous sampling is valuable when the phase relationship between mechanical or electrical channels must be retained. In process monitoring, the eight-input structure can reduce the number of separate converter packages required when several analog measurements share a controller. The primary design consideration is matching the sampling architecture to the signal relationship being measured. Simultaneous sampling improves channel-to-channel timing consistency, but applications that only need independent sequential readings should still evaluate acquisition latency, input bandwidth, and output timing. PCB layout should preserve clean analog grounding, provide local decoupling, and keep digital interface routing away from sensitive input paths. This page consolidates the verified distributor descriptions, package information, throughput figures, application guidance, and available same-family alternatives. It also distinguishes documented parameters from information that still requires confirmation from the MAX115/MAX116 manufacturer datasheet.
MAX11607EWC+ - 10-Bit 4-Ch I2C ADC 94.4 kSps | Maxim Integrated
The Maxim Integrated MAX11607EWC+ is a 10-bit, low-power, multi-channel successive-approximation analog-to-digital converter (SAR ADC) with an I2C-compatible 2-wire serial interface, supplied in a 12-ball WLP (Wafer-Level Package) measuring 2.14 mm x 1.56 mm. The device integrates an internal track/hold amplifier, voltage reference, and conversion clock, sampling up to 94.4 kSps while drawing only 670 uA at maximum throughput. It operates from a single 2.7 V to 3.6 V supply, making it a strong fit for low-voltage, battery-powered designs. An SAR ADC is a type of analog-to-digital converter that uses a successive-approximation register and an internal DAC to binary-search the input voltage against a reference, producing one bit per clock cycle in a fixed N-cycle conversion. SAR ADCs sit within the broader ADC hierarchy (SAR -> Nyquist-rate ADC -> data converter -> mixed-signal IC), and are prized for deterministic latency, low power, and excellent DC accuracy at moderate sample rates compared to delta-sigma or pipelined architectures. Key features of the MAX11607EWC+ include 4 analog input channels (configurable for unipolar or pseudo-differential operation on related family parts), 10-bit resolution with no missing codes, an internal 2.5 V reference (also configurable to use an external reference), a 2-wire I2C-compatible interface with software-configurable slave addresses, and an industrial operating temperature range of -40 C to +85 C. The wide supply range and low quiescent current suit battery-powered and portable instruments. The internal 2.5 V bandgap reference, single-cycle conversion, and high-impedance analog inputs let designers replace larger discrete ADC front-ends. The compact WLP-12 footprint frees board area in space-constrained wearables and sensor modules, and the I2C interface minimizes GPIO consumption on low-pin-count microcontrollers. Typical applications include handheld battery-powered instrumentation, sensor signal conditioning and digital conversion (temperature, pressure, strain-gauge bridges via front-end gain stages), portable medical devices such as glucose meters and pulse oximeters, factory automation modules, and consumer audio front-end level metering. The 4-channel input is ideal when several sensors share one ADC. When designing with this device, place 0.1 uF bypass capacitors close to the AVDD pin and route analog and digital grounds as separate planes joined at a single point. For inputs exceeding the internal reference range, add an external front-end attenuator or use the external-reference mode with a higher-VREF source. Verify I2C pull-up sizing for the target bus speed (up to 1.7 MHz on this family) and the master's sink current capability.

MAX11615EEE+TC78 - 12-Bit 8-Ch I²C Low-Power ADC | Maxim Integrated
The Maxim Integrated (Analog Devices) MAX11615EEE+TC78 is a low-power, 12-bit, 8-channel successive-approximation analog-to-digital converter (SAR ADC) with internal track/hold, voltage reference, clock, and an I²C-compatible 2-wire serial interface, supplied in a 16-pin QSOP package on a 178 mm (7-inch) Tape & Reel carrier format (TC78 reel code). A SAR ADC (Successive Approximation Register Analog-to-Digital Converter) is a type of low-power, medium-resolution data converter that uses a binary search algorithm against an internal DAC to digitize an analog input in N conversion cycles for N-bit resolution. SAR ADCs sit within the data-converter IC family, which belongs to the broader mixed-signal semiconductor category. They are favored in multiplexed channel applications because they offer deterministic latency, low quiescent power, and a small package footprint versus integrating or pipeline ADCs. The MAX11615EEE+TC78 operates from a single 2.7V to 3.6V supply, draws only 670 µA at the maximum 94.4 ksps sampling rate, and supports both 400 kHz Fast-Mode and 1.7 MHz High-Speed-Mode I²C operation. On-chip features include an internal 2.048V reference, an internal oscillator, software-configurable unipolar/bipolar input range, and four GPIO-capable digital I/O pins that can be used for analog input channel expansion. The QSOP-16 footprint makes it well-suited for space-constrained portable instruments. Typical applications include portable and battery-powered data loggers, handheld multimeters, patient monitoring front-ends, industrial sensor conditioning loops, 4–20 mA loop powered transmitters, programmable logic controllers (PLCs), and consumer audio front-panel control. The wide analog input range and internal reference simplify the analog front-end while keeping external component count low. When designing with this ADC, place 0.1 µF decoupling capacitors as close as possible to the AVDD and DVDD pins, and use a low-impedance analog ground plane to minimize channel-to-channel crosstalk. The I²C address is hardware-selectable via the AD0 pin, allowing two devices to coexist on the same bus without external glue logic.

MAX11627EEE/V+ - 12-Bit 300ksps 4-Ch ADC | Analog Devices
The Analog Devices MAX11627EEE/V+ is a 12-bit, 300 ksps, low-power, 4-channel SAR analog-to-digital converter with an integrated 4.096V reference, FIFO buffer, and SPI-compatible serial interface, housed in a 16-pin QSOP package. The /V suffix denotes the automotive-grade temperature range (-40C to +85C) screened variant of the base MAX11627EEE+ industrial-grade ADC. An SAR (Successive Approximation Register) ADC is a type of analog-to-digital converter that uses a binary search algorithm and a precision DAC to converge on the input voltage in N conversion cycles, where N equals the bit resolution. SAR ADCs sit within the broader hierarchy of data-converter ICs (ADC -> data converter -> mixed-signal IC -> semiconductor) and are favored for medium-speed, medium-resolution applications where deterministic latency, low power, and small package size matter more than the very highest sample rates. The MAX11627 family (MAX11626/MAX11627/MAX11628/MAX11629) shares a common core and differs primarily in input channel count: 4 / 4 / 8 / 12 channels respectively. Key features of the MAX11627EEE/V+ include 300 ksps throughput, an internal 4.096V reference (eliminates external reference IC and saves BOM cost), a 16-deep FIFO that offloads host-processor interrupts, single 5V analog supply operation, low 3.5 mA supply current at full speed, and a hardware-/CSB-only shutdown mode that drops current to < 10 uA. The 16-QSOP footprint is industry-standard for multi-channel SAR ADCs, enabling drop-in placement on existing designs that already use a 16-pin QSOP ADC. Architecturally, the MAX11627 is built on a CMOS process with a switched-capacitor SAR core, an integrated low-drift bandgap reference, a 4-input analog multiplexer with track-and-hold, and an SPI-compatible mode-0/mode-3 serial interface that supports daisy-chaining of multiple devices on a single bus. The internal FIFO decouples conversion throughput from host read latency, allowing the host to burst-read groups of samples efficiently. Typical applications include portable industrial data loggers, multi-loop process-control analog input modules, automotive sensor interfaces, battery-cell voltage monitoring, and HVAC controller boards. The 4-channel count matches the typical "current + temperature + pressure + flow" sensor bundle for a single machine subsystem. When designing with this device, note that the 5V analog rail (AVDD) and the 3V/5V digital rail (DVDD) are independent supplies and must be decoupled separately. The internal reference does not require an external bypass capacitor, but adding 0.1 uF + 10 uF on AVDD and 0.1 uF on DVDD is recommended to keep digital switching noise out of the SAR conversion result.

MAX11627EEE/V+CLS - 12-Bit 300ksps SAR ADC | Maxim Integrated
The Maxim Integrated MAX11627EEE/V+CLS is a 12-bit, 300ksps successive-approximation analog-to-digital converter with a 16-entry FIFO and internal 2.5V reference, offered in a 16-pin QSOP package. The automotive-grade +V/CLS suffix indicates parts tested to customer-specific lot and screening requirements, paired with a 12-bit SAR core, four analog input channels, and a 10MHz SPI/QSPI/MICROWIRE-compatible serial interface. A successive-approximation register (SAR) ADC is a converter architecture that performs one bit-trial per clock cycle using an internal binary-weighted capacitor DAC and a comparator, trading absolute speed for low power consumption and deterministic latency. The MAX11627 belongs to the wider MAX11626-MAX11629 ADC family - all 4-/8-/12-/16-channel low-cost SAR converters with FIFO and on-chip reference - which sit inside the Maxim precision-data-converter portfolio alongside higher-throughput pipeline ADCs and sigma-delta converters. SAR parts are commonly chosen for multiplexed multi-channel sensor acquisition where the channel-to-channel latency must remain deterministic for control-loop stability. Key parametric features include ±1 LSB INL and ±1 LSB DNL with no missing codes over temperature, an internal 2.5V reference (also supports an external 1V to VDD reference), a 16-entry FIFO with scan-mode and internal averaging, an internal conversion clock, and a 4-channel analog input mux. The 16-pin QSOP package is the same physical footprint used across the MAX11626/MAX11627/MAX11628/MAX11629 family, allowing direct PCB migration between channel counts within the family. The architecture is a classic charge-redistribution SAR with a sample-and-hold front end and a 12-bit resolution core. The internal FIFO offloads 16 conversion results, enabling burst-mode acquisition without continuous processor intervention and reducing SPI bus traffic for power-constrained MCUs. Typical applications include automotive sensor acquisition (battery monitoring, current sensing, position feedback), industrial process control loops, multi-channel data loggers, portable instrumentation, and factory-automation front-ends. The +CLS automotive suffix makes this specific variant preferred for safety-critical or harsh-environment designs where customer-specific lot traceability is contractually required. A key design consideration is that the FIFO depth and scan-mode registers must be configured via the SPI before conversion start; misprogramming the scan-mode register is the most common cause of missing-channel errors in production. Inputs AIN0-AIN3 are software-muxed; unused analog inputs should be tied to mid-supply to minimize crosstalk into the active channel. This page synthesizes distributor pricing, parametric proximity analysis against same-family drop-in parts, and practical SPI configuration notes that are not consolidated in any single manufacturer document.
MAX11627EEE/V+T - 12-Bit 300ksps SAR ADC w/ FIFO | Maxim
The Maxim Integrated (Analog Devices) MAX11627EEE/V+T is a 12-bit, 300 ksps, low-power successive-approximation analog-to-digital converter with 4 analog input channels, an internal 2.5V reference, an internal 2.048 MHz oscillator, and a 16-entry FIFO housed in a 16-pin QSOP package. The /V suffix denotes the automotive-grade (AEC-Q100) screening, and the +T suffix denotes tape-and-reel packaging. The MAX11627 is part of a six-member family (MAX11626-MAX11629 and MAX11632/MAX11633) that shares a common serial interface and pinout but differs in channel count, reference voltage, and FIFO depth. A successive-approximation register (SAR) ADC is a sampling converter architecture that performs one bit decision per internal clock cycle using a binary-search algorithm against a precision DAC. SAR ADCs are valued for deterministic latency, no pipeline delay, and excellent DC accuracy at moderate sample rates, placing them between low-speed delta-sigma converters and high-speed pipeline ADCs in the data-converter hierarchy. The 16-entry FIFO on the MAX11627 decouples the host sample rate from the conversion rate, allowing the host to sleep between block transfers and reducing SPI bus traffic in power-constrained or interrupt-driven embedded designs. Key features include 4 single-ended analog inputs (0 to VREF range), 12-bit resolution with ±1 LSB INL and ±1 LSB DNL and no missing codes over temperature, 300 ksps maximum throughput, an internal 2.5V reference, scan-mode auto-sequencing, internal averaging, 10 MHz SPI/QSPI/MICROWIRE-compatible serial interface, an internal clock that eliminates an external crystal, and a low 2.7V-3.6V analog supply. The /V automotive variant adds extended qualification per AEC-Q100, suiting the part for body-electronics, sensor, and industrial-sensor applications where -40C to +85C operation is required. Typical applications include automotive sensor interfaces (e.g., pedal position, throttle, HVAC flap position), industrial multi-channel data-acquisition modules, battery-monitoring systems for 12V/24V lead-acid and lithium packs, portable instrumentation front ends, and any 3.3V-rail embedded design that needs 12-bit multi-channel conversion with host-monitored data movement. The internal reference and internal clock minimize external BOM, while the FIFO reduces microcontroller wake-up frequency for power-budget-sensitive applications. When designing with the MAX11627EEE/V+T, place the 0.1 uF + 10 uF decoupling pair as close as possible to AVDD and DVDD pins, keep the analog input traces short and guarded, and bypass REF with the 10 uF capacitor recommended in the manufacturer datasheet. The internal reference can source up to 1 mA, so any external load beyond ratiometric must be buffered. This page synthesizes distributor pricing, FIFO-aware firmware design notes, AEC-Q100 qualification details, and drop-in replacement options not aggregated in the manufacturer datasheet, providing a single engineering decision surface for embedded design teams evaluating the MAX11627 family.
MAX11627EEE/V+TCLS - 12-Bit 300ksps ADC w/ FIFO, QSOP-16 | Maxim
The Maxim Integrated (Analog Devices) MAX11627EEE/V+TCLS is a 12-bit, 300 ksps successive-approximation ADC with internal reference and FIFO in a 16-pin QSOP package. It combines an SPI/QSPI/MICROWIRE-compatible serial interface, internal 4.096 V reference, and an internal FIFO that simplifies burst sampling without host intervention. An ADC (Analog-to-Digital Converter) is a semiconductor device that converts a continuous-time analog voltage into a discrete digital code. Successive-approximation (SAR) ADCs use an internal DAC and comparator to binary-search the input, achieving 12-bit resolution at up to 300 ksps while consuming only a few milliwatts. SAR ADCs sit within the broader hierarchy of mixed-signal ICs and are widely used in industrial control, instrumentation, and sensor-interface signal chains where moderate speed and precision are required. Key specifications include 12-bit resolution, 300 ksps maximum sampling rate, single-ended analog inputs across 4, 8, 12, or 16 channels (family-wide), an internal 4.096 V reference, an internal FIFO for autonomous burst capture, and a low-power shutdown mode. The QSOP-16 (5.0 mm × 3.0 mm body) package exposes all analog, digital, and power pins, while the SPI serial interface supports daisy-chaining of multiple MAX1162x devices on a single bus. Internally, the device uses a capacitive charge-distribution SAR architecture, an on-chip bandgap-derived reference with factory-trimmed accuracy, and dedicated input track-and-hold circuitry. The result is excellent AC performance at low conversion rates without requiring external precision components or calibration. Typical applications include multichannel data-acquisition front ends, patient monitoring, sensor-array sampling, HVAC controllers, and portable instrumentation. The wide channel count and FIFO make the device well suited to scanning multiple analog signals before waking a microcontroller to read the conversion queue. Design with this part using the recommended 0.1 uF decoupling capacitor close to VDD, and place the analog inputs on quiet ground-referenced traces routed away from switching lines. Confirm that host MCU SPI timing satisfies the 40 ns minimum SCLK period specified in the datasheet. This page synthesizes distributor stock, drop-in alternatives, and design notes that the manufacturer datasheet alone does not aggregate.
MAX1162ACUB+T - 16-Bit 200ksps +5V SAR ADC | Analog Devices
The Analog Devices (Maxim Integrated) MAX1162ACUB+T is a 16-bit, 200 ksps successive-approximation analog-to-digital converter (SAR ADC) with a single +5V supply input, an automatic power-down feature that drops quiescent current to 10 µA between conversions, and a high-speed 1.1 µs wakeup time, housed in a 10-pin µMAX (TSSOP-equivalent) package. A SAR ADC is a type of data converter that performs a binary search through an internal capacitive DAC to digitize an analog signal in N conversion cycles for N bits of resolution. As part of the broader data-acquisition signal chain (sensor -> front-end amplifier -> anti-alias filter -> ADC -> digital host), SAR ADCs are prized for deterministic latency, low latency-to-sample ratios, and excellent DC accuracy without the pipeline delay of pipelined architectures. Key specifications include 16-bit no-missing-codes performance, an input-voltage range of 0 to VREF, an internal 4 MHz track-and-hold, an SPI/QSPI/MICROWIRE-compatible serial output. The MAX1162ACUB+T integrates the reference buffer internally, so only an external reference voltage (typically +5V for full-scale) is required. The automatic shutdown between conversions reduces average supply current dramatically at lower throughput rates, making the part ideal for battery-powered and duty-cycled applications. Architecture-wise, the device uses a charge-redistribution capacitive DAC array combined with a precision comparator and successive-ration logic, with an internal input track-and-hold that accepts fast-slewing signals up to the conversion rate without external buffering. The serial interface is straightforward: CS, DOUT, and SCLK form a standard 3-wire SPI port compatible with most microcontrollers and DSPs. Typical applications include portable data loggers, hand-held measurement instruments, battery-powered sensors and instrumentation, industrial process control analog front-ends, and medical monitoring devices. Its small 10-pin uMAX footprint suits space-constrained PCB designs where density matters. When designing with this ADC, allocate adequate settling time for the external reference and add a 0.1 µF bypass capacitor close to VDD. The SSTRB (or DSP-style) output can be polled to confirm conversion completion before clocking out results. This page synthesizes distributor pricing, same-package drop-in alternatives, and practical design notes beyond what the manufacturer datasheet alone provides.
MAX1162AEUB+T - 16-Bit 200ksps SAR ADC | Analog Devices/Maxim
The Analog Devices / Maxim Integrated MAX1162AEUB+T is a 16-bit, 200ksps, low-power successive-approximation analog-to-digital converter (ADC) housed in a 10-pin uMAX/uSOP surface-mount package. The part operates from a single +5V supply, supports an input range of 0V to VREF, and offers 16-bit resolution with no missing codes. Average active supply current is on the order of a few milliamps, while automatic power-down between conversions drops quiescent current to 10uA, and wakeup from shutdown is 1.1us. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that samples a continuous analog voltage and converts it into a discrete digital code word. SAR (successive-approximation register) ADCs in particular use an iterative binary-search algorithm against an internal DAC, combining low latency with deterministic conversion time, making them well suited to multiplexed data-acquisition channels and control loops. The MAX1162AEUB+T fits within the broader hierarchy: ADC -> data converter -> mixed-signal IC -> semiconductor. Key features include an internal track-and-hold with 4MHz input bandwidth, an adjustable logic interface from +2.7V to +5.25V for easy connection to modern microcontrollers, hardware-software shutdown control, and an external reference input that lets the user trade full-scale range for noise. The 10-pin uMAX (10-uMAX/uSOP) package is compact enough for portable designs while exposing the SAR core's high-speed serial interface. Architecturally the MAX1162 uses a charge-redistribution SAR core with dedicated input T/H, allowing accurate acquisition of full-scale transitions at full 200ksps throughput. Serial data is clocked out LSB-first under user control, simplifying connection to SPI/QSPITM/MICROWIRE-compatible controllers or DSP serial ports. Operating temperature range spans -40C to +85C industrial grade. Typical applications include portable instrumentation and battery-powered data loggers, industrial process-control front ends, pen-tablet digitizers and touch-screen A/D channels, and medical instrument signal conditioning. The combination of low active power, automatic power-down, and fast wakeup makes it especially attractive for battery-powered data-acquisition systems that spend most of their time idle between conversions. A key design consideration is decoupling: place a 0.1uF ceramic bypass capacitor as close as possible to the AVDD pin and a bulk tantalum/ceramic reservoir on the logic supply side. Choose an external reference (such as the MAX6126) sized to the desired full-scale input and remember that conversion noise and INL will directly reflect reference quality. This page synthesizes distributor pricing, drop-in same-brand and cross-brand alternatives, and practical design guidance not found in the manufacturer datasheet, helping engineers select, source, and lay out the MAX1162AEUB+T with confidence.
MAX1165ACUI+ - 16-Bit 165ksps SAR ADC, Parallel | Maxim
The Maxim Integrated MAX1165ACUI+ is a 16-bit, low-power, successive-approximation analog-to-digital converter (SAR ADC) with a maximum sampling rate of 165 ksps and a single-ended analog input channel. It is housed in a 28-pin TSSOP package and uses a single +5V analog supply with automatic power-down between conversions, reducing supply current to microampere levels during idle intervals. An on-chip +4.096V reference and a track-and-hold front end eliminate the bulk of external analog design. An ADC (Analog-to-Digital Converter) is a mixed-signal data converter that transforms a continuous analog voltage into a discrete digital code, enabling microcontrollers, FPGAs, and DSPs to process real-world sensor and instrumentation signals. Successive-approximation ADCs use an internal binary-search algorithm combined with an internal DAC to resolve the input one bit per clock cycle, balancing speed, resolution, and power consumption. The MAX1165 family sits in the precision mid-speed converter segment of the data-converter hierarchy: ADC -> SAR ADC -> precision data converter -> mixed-signal IC -> semiconductor. Key specifications include 16-bit resolution with no missing codes, ±1 LSB INL (typical), ±0.5 LSB DNL (typical), and an aperture bandwidth compatible with 165 ksps throughput. The parallel interface (8+8 byte-mode or 16-bit word-mode) provides glitch-free readback without the timing overhead of a serial ADC, and the part offers software-configurable input ranges via the input scaling network. The TSSOP-28 footprint gives a compact 0.65 mm pitch, surface-mount solution suitable for high-density data-acquisition boards. Typical applications include industrial process-control loops, portable instrumentation and data loggers, battery-powered medical monitors, and multi-channel data-acquisition front ends using an external MUX. The wide input range and integrated reference simplify board-level design, while parallel output enables direct connection to a microcontroller external memory bus for high-throughput captures. When designing with this device, ensure the analog input is bandwidth-limited (RC filter, typically 1 kΩ/1 nF) to avoid aliasing, and add 0.1 µF decoupling close to AVDD and DVDD. The PD pin can be tied to a microcontroller GPIO for power management in portable designs. Compute scheme, supplier scheme, and pin-compatible Scheme B variants are summarized in the comparison table below.
