MAX157BEPA

MAX157BEPA - 10-Bit 108ksps 2-Ch Serial ADC | Maxim Integrated

The Maxim Integrated MAX157BEPA is a +2.7V, low-power, 2-channel, 108 ksps, 10-bit successive-approximation analog-to-digital converter (ADC) housed in an 8-pin PDIP (DIP-8) through-hole package. The MAX157BEPA delivers a single-ended analog input, on-chip 4.096 MHz oscillator, and a high-speed 3-wire SPI/QSPI/MICROWIRE-compatible serial interface that streams conversion results directly to a microcontroller or DSP. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that quantizes a continuous analog voltage into a discrete digital code. Successive-approximation ADCs use an internal DAC and comparator to binary-search the input against reference-derived levels, trading off conversion speed against die area and power. The MAX157BEPA belongs to the successive-approximation ADC family, which is the dominant topology for general-purpose 8-to-16 bit industrial data-acquisition and instrumentation applications because it delivers a deterministic conversion time and low latency compared with delta-sigma converters. Key specifications include 2 single-ended input channels, 10-bit resolution, 108 ksps maximum sampling rate, 7.4 µs successive-approximation conversion time, automatic power-down between conversions, fast 2.5 µs wake-up, on-chip clock, and 3-wire serial output. Operating from a single +2.7V to +5.25V supply, the part consumes only 3.2 mW at VDD = +3.6 V at full sampling rate and drops to microamp-level standby current in power-down mode, making it well suited for battery-powered and energy-harvesting designs. The MAX157BEPA uses a classic switched-capacitor charge-redistribution SAR architecture with an input track-and-hold, internal reference, and an on-chip 4.096 MHz oscillator. This architecture provides excellent linearity, low aperture uncertainty, and deterministic throughput at 108 ksps, supporting both single-shot and continuous conversion sequences without external clock conditioning. Typical applications include portable data loggers, handheld multimeters, industrial process transmitters, weigh scales, isolated sensor front-ends, panel meters, and consumer measurement equipment. The DIP-8 package suits prototype breadboarding, through-hole production, and socket-based test fixtures where surface-mount parts are impractical. Designers favor this part for its small footprint, single-supply operation, and easy 3-wire interface. When laying out the PCB, keep analog and digital ground returns short and join them at one star point near the ADC GND pin. Place a 0.1 µF decoupling capacitor within a few millimeters of the VDD pin and a 10 µF bulk cap on the supply for low-noise operation. The input source impedance should stay under 5 kΩ to preserve linearity; add an input buffer if your signal source exceeds this limit. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, including thermal performance, PCB layout recommendations, and a side-by-side comparison against the MAX157BEPA+ and MAX159 same-family variants.

MAX157BEPA+ - 10-Bit 108ksps 2-Ch Serial ADC | Maxim Integrated
MAX157BEPA+

MAX157BEPA+ - 10-Bit 108ksps 2-Ch Serial ADC | Maxim Integrated

The Analog Devices / Maxim Integrated MAX157BEPA+ is a +2.7V, low-power, 2-channel, 108ksps, serial 10-bit successive-approximation analog-to-digital converter (ADC) housed in an 8-pin PDIP (through-hole DIP) package. The device integrates a precision 2-channel analog input multiplexer, a sample-and-hold amplifier, an on-chip clock, and a high-speed 3-wire SPI/QSPI/MICROWIRE-compatible serial interface in a single monolithic IC, drawing only 3.2 mW at VDD=+3.6V at full sampling rate. A successive-approximation ADC (SAR ADC) is a type of analog-to-digital converter that uses a binary-search algorithm against an internal capacitive or resistive DAC to digitize an analog input one bit at a time per clock cycle. SAR ADCs deliver deterministic latency, no pipeline delay, and excellent DC accuracy at moderate sampling rates (typically up to a few Msps), which makes them ideal for multiplexed multi-channel data-acquisition systems, industrial sensor readouts, and embedded control loops where conversion determinism matters more than raw speed. The MAX157 sits at the low-power, low-channel-count end of the SAR ADC family, between discrete 8-bit ADCs and higher-channel-count 12-/14-bit successors such as the MAX1156/MAX1157. Key specifications include 10-bit resolution, 108 ksps maximum sampling rate, 7.4 µs successive-approximation conversion time, 2.5 µs wake-up time from automatic power-down, single +2.7V to +5.25V analog supply, and an internal 2.048V or external reference option. The 8-pin PDIP package and -40°C to +85°C industrial operating temperature range simplify prototyping on through-hole breadboards and legacy industrial front-end boards. Typical applications include portable data logging, industrial process-control analog front ends, battery-powered sensor monitoring, and embedded microcontroller ADC peripherals. Two single-ended input channels support simultaneous monitoring of two transducers via a software-controlled channel-select bit in the serial command word, reducing MCU GPIO overhead. Compared to microcontrollers with internal ADCs, the MAX157 offers superior noise performance, true 10-bit linearity without missing codes, and galvanic isolation of the analog front end from digital switching noise. When designing with this part, place 0.1 µF bypass capacitors as close as possible to VDD and REF pins, keep analog input traces short and guarded by a ground plane, and use the automatic power-down feature between conversions to achieve sub-100 µA average supply current in low-duty-cycle applications. The +5.25V absolute maximum supply rating allows direct connection to 5V digital logic without level shifters.

MAX158ACWI+ - 8-Channel 8-Bit 400ksps ADC | Maxim Integrated
MAX158ACWI+

MAX158ACWI+ - 8-Channel 8-Bit 400ksps ADC | Maxim Integrated

The Maxim Integrated MAX158ACWI+ is a CMOS high-speed 8-bit analog-to-digital converter with eight analog input channels, an integrated 2.5V on-chip reference, and a track/hold amplifier, packaged in a 28-pin wide-body SOIC (SOIC-Wide-28). It performs successive-approximation conversions in 2.5 us per channel and supports throughput rates up to 400 ksps when sequentially sampling all eight inputs. The + suffix indicates lead-free, RoHS-compliant lead finish per Maxim Integrated ordering nomenclature. An ADC (Analog-to-Digital Converter) is a data-acquisition component that converts continuous analog signals into discrete digital codes for processing by microcontrollers, DSPs, or FPGAs. Within the broader hierarchy, the MAX158 sits at successive-approximation register (SAR) ADC -> ADC -> data converter -> data acquisition IC -> signal-chain IC -> integrated circuit. Eight-channel, single-supply, parallel-output ADCs of this class are typically used in embedded systems where multiple sensor or process variables must be digitized with a single mixed-signal device. Key features include eight single-ended analog inputs with channel selection, an internal 2.5V bandgap reference, an on-chip track/hold amplifier, and a parallel digital interface that simplifies connection to 8-bit data buses. The device operates from a single +5V analog supply, draws modest supply current, and accepts 0V to +5V unipolar analog inputs in normal operation. Internal reference and input MUX integration reduce external component count on the BOM. The architecture combines a capacitive-charge redistribution DAC with successive-approximation logic and a dedicated track/hold front-end, enabling 2.5 us conversion times per channel. The eight-input analog multiplexer allows software-configurable channel sequencing, and the 2.5V reference is trimmed for low drift, supporting repeatable measurement accuracy across the commercial 0C to +70C temperature range. Typical applications include multi-loop process control, panel-meter and instrumentation front-ends, automotive sensor aggregation, factory automation data-acquisition cards, portable data loggers, and embedded industrial-control boards where multiple analog signals must be sampled by a single host processor. The wide SO-28 footprint is friendly to hand-soldered prototypes and through-hole-compatible PCB layouts. When designing with this device, ensure the analog input driving source presents low output impedance (an op-amp buffer is typically placed ahead of the MUX) and decouple AVDD and DVDD separately to prevent digital switching noise from corrupting the conversion. Per the manufacturer datasheet, an external reference may be substituted by overdriving the internal reference node when higher stability or lower noise is required.

MAX158AEPI+ - 8-Ch 8-Bit 400ksps ADC w/ Mux & Ref | Maxim
MAX158AEPI+

MAX158AEPI+ - 8-Ch 8-Bit 400ksps ADC w/ Mux & Ref | Maxim

The Maxim Integrated (now Analog Devices) MAX158AEPI+ is a CMOS high-speed, 8-bit analog-to-digital converter with 8 analog input channels, an internal 2.5V bandgap reference, and a track/hold amplifier, delivered in a 28-pin PDIP through-hole package. It converts at up to 400 ksps using a successive-approximation architecture with software-configurable unipolar/bipolar input ranges and single +5V analog and digital supply operation. An 8-bit ADC (analog-to-digital converter) is a data-acquisition component that maps a continuous analog input voltage into one of 256 discrete digital codes; successive-approximation ADCs balance speed, resolution, and cost for general-purpose embedded sensing, instrumentation, and process-control applications. Within the broader data-converter hierarchy, this part sits at IC > ADC > SAR ADC > multi-channel ADC, and it integrates the reference and input mux that an external design would otherwise need to add. Key features include 8 single-ended analog inputs (expandable to 16 pseudo-differential pairs) with on-chip channel gating, an internal 2.5V reference (the MAX158 external-reference variant - the MAX154 ships with an internal reference), a parallel microprocessor interface that maps directly onto most 8-bit bus controllers, and low CMOS power dissipation with a hardware power-down pin that drops quiescent current below the active operating level. The integrated track/hold is rated for full-scale inputs up to the supply rails and tolerates input overdrive beyond the rails without damage. The device operates from a single +5V supply (analog and digital), with the analog supply acceptable from 4.75V to 5.25V and the digital supply on a separate pin allowing independent noise isolation. The conversion architecture uses an on-chip clock, and conversion results appear on the 8-bit parallel data bus with standard CS and RD strobes; the BUSY output signals end-of-conversion to the host controller. Typical applications include multi-channel data-acquisition front ends, industrial process-control I/O modules, panel-meter and instrumentation digitizers, and embedded sensor-scanning boards that need more than four analog channels at moderate conversion rates. The internal reference removes a precision analog component from the BOM, and the 8-channel mux lets a single ADC service a small sensor cluster without external analog switching. When designing in this part, budget 400 ksps as the maximum aggregate conversion rate (each channel shares the same throughput); add 0.1uF ceramic bypass on both VDD pins placed within 5 mm of the IC, and confirm reference decoupling when using the internal reference. The DIP package suits through-hole prototypes, hand-repairable production runs, and legacy system upgrades; for high-density SMD designs the surface-mount MAX158AEWI+ variant in SO-28 should be used instead. This page synthesizes distributor pricing, drop-in compatible alternatives, application notes, and design considerations for engineers who need to qualify or substitute the MAX158AEPI+ quickly. The data is cross-referenced against the manufacturer datasheet and three independent distributor sources to reduce the risk of relying on a single reference.

MAX159ACUA - 10-Bit, 108ksps, 2-Ch Serial ADC µMAX | Maxim
MAX159ACUA

MAX159ACUA - 10-Bit, 108ksps, 2-Ch Serial ADC µMAX | Maxim

The Maxim MAX159ACUA is a +2.7V low-power, 2-channel, 108ksps, serial 10-bit successive-approximation analog-to-digital converter (ADC) housed in an 8-pin µMAX (UMAX-8) surface-mount package. Operating from a single +2.7V to +5.25V analog supply, the device integrates an on-chip clock, automatic power-down between conversions, fast 2.5µs wake-up, and a high-speed 3-wire SPI/QSPI/MICROWIRE-compatible digital interface that allows direct connection to most microcontrollers and DSPs. An analog-to-digital converter is a mixed-signal integrated circuit that samples an analog input voltage and converts it into a discrete digital code proportional to the input magnitude. Successive-approximation register (SAR) ADCs like the MAX159ACUA achieve a deliberate balance between speed, accuracy, and power consumption by performing one comparison per clock cycle against an internal binary-weighted capacitor DAC, finishing a 10-bit conversion in 7.4µs. SAR ADCs sit within the broader hierarchy: ADC -> data converter -> mixed-signal IC -> semiconductor, and are preferred over flash and sigma-delta converters in cost-sensitive, low-power, multiplexed-channel applications such as sensor front ends. Key features include 108 ksps throughput, ±0.5 LSB INL (max), single +2.7V to +5.25V supply operation, automatic power-down that drops supply current between samples, internal 2.5µs wake-up time, and an on-chip clock that eliminates the need for an external timing component. The MAX159ACUA supports 2 analog input channels, integrates an input track-and-hold, and is specified for the commercial 0°C to +70°C operating temperature range. It is a member of the MAX157/MAX159 family that shares the same pinout and registers, easing firmware reuse and BOM flexibility. Typical applications include portable and battery-powered data acquisition, temperature and pressure sensor digitizing loops, pen/digitizer tablets, patient monitoring front ends, and process-control I/O modules. Because the part automatically powers down between conversions, it is well suited to loop-powered 4-20mA sensors, isolated SPI ADC front ends, and handheld instruments where total system current must be minimized. The 3-wire serial interface is compatible with SPI, QSPI, and MICROWIRE hosts, allowing seamless connection to common microcontrollers. When designing with this device, place the 10µF bypass capacitor as close as possible to the VDD lead and keep analog input traces short and guarded, since the SAR architecture is sensitive to charge-injection transients during acquisition. Note that the MAX159ACUA is no longer in active production per the partstack listing; consider MAX159ACUA+ for current orders or MAX157BCPA in a PDIP-8 footprint for legacy through-hole boards.

MAX159BCPA

MAX159BCPA - 10-bit 108ksps 2-Ch Serial ADC | Maxim Integrated

The Maxim Integrated MAX159BCPA is a low-power, 10-bit, 2-channel, 108 ksps analog-to-digital converter (ADC) with a high-speed 3-wire serial interface, offered in an 8-pin PDIP (DIP-8) through-hole package. It operates from a single +2.7V to +5.25V supply, draws only 3.2 mW at VDD = +3.6V at the maximum conversion rate, and integrates an on-chip clock, an internal 2.5 µs track/hold, and automatic power-down between conversions for battery-sensitive applications. An analog-to-digital converter (ADC) is a data-acquisition integrated circuit that converts real-world analog signals - such as temperature, pressure, or sensor outputs - into a digital code that a microcontroller or processor can interpret. Successive-approximation (SAR) ADCs like the MAX159 sample an input through a track/hold, then compare the held voltage against a binary-weighted internal DAC bit-by-bit until a 10-bit result is registered. SAR converters sit at one level of the hierarchy: ADC -> data converter -> signal-chain IC -> mixed-signal semiconductor. The MAX159 family targets low-power, low-channel-count systems where SPI/QSPI/MICROWIRE compatibility simplifies glue logic. Key features include 2 single-ended analog input channels (AIN0, AIN1) multiplexed into the SAR core, an external clock or internal oscillator option, ±1 LSB (max) differential non-linearity (DNL) and ±1 LSB (max) integral non-linearity (INL) over the operating range, and a wake-up time of just 2.5 µs from power-down. The 8-pin PDIP package simplifies breadboard prototyping and field-serviceable designs, making the device popular in industrial control front ends and portable instrumentation. The MAX159 uses a charge-redistribution DAC architecture for the SAR conversion and a quiet reference-input path; the supply-rejection topology lets the part operate directly from a noisy 3.3V or 5V rail without an external LDO for many applications. Two digital inputs (CS, SCLK) and one digital output (DOUT) constitute the serial port compatible with SPI, QSPI, and MICROWIRE masters at up to 2.5 MHz. Typical applications include battery-powered handheld meters, portable data loggers, isolated sensor front ends, thermocouple cold-junction compensation boards, and touch-panel digitizers. Designers also use it as a 2-channel replacement for legacy microcontroller-integrated ADCs when more channels or better DC accuracy are required. When designing with this device, place a 0.1 µF bypass capacitor within 5 mm of the VDD pin and keep the analog input traces short and guarded. The reference voltage (REF) needs to be a low-noise source; use a 10 µF ceramic plus 0.1 µF decoupling pair at REF.

MAX159BEPA - 10-Bit 108ksps 2-Ch Serial ADC | Maxim Integrated

The Maxim Integrated (Analog Devices) MAX159BEPA is a low-power, 10-bit, 2-channel, 108 ksps successive-approximation analog-to-digital converter (ADC) housed in an 8-pin PDIP package. The part operates from a single +2.7 V to +5.25 V supply and integrates a 7.4 µs SAR core, an on-chip clock, automatic power-down between conversions, and a high-speed 3-wire SPI/QSPI/MICROWIRE-compatible serial interface. An ADC (analog-to-digital converter) is a semiconductor component that converts a continuous analog voltage into a discrete digital code. Successive-approximation register (SAR) ADCs are a widely used architecture that uses a binary search across an internal DAC to determine each bit of the output code, one bit per clock cycle. They offer an excellent trade-off between speed, resolution, and power for sampling rates up to a few megasamples per second. SAR ADCs sit within the broader hierarchy: ADC -> data converter -> mixed-signal IC -> semiconductor. The MAX159BEPA belongs to this family, optimized specifically for low-power, low-channel-count applications. Key specifications include 10-bit resolution, 108 ksps sampling rate, 2 analog input channels, 7.4 µs conversion time, 2.5 µs wake-up from power-down, and a low supply current that drops dramatically in power-down mode. The 3-wire serial interface shares DIN, SCLK, and DOUT lines, simplifying the connection to any microcontroller. The MAX159 also includes an external reference input, giving designers flexibility to trade noise performance against dynamic range. Typical applications include portable battery-powered instrumentation, data loggers, sensor front ends (temperature, pressure, strain gauges), loop-powered industrial transmitters, pen tablets and touch-screen controllers, and isolated multi-channel data acquisition modules where a small-footprint, low-power ADC is required. When designing with this part, choose the external reference voltage carefully: the ADC's input range scales directly with VREF, and its noise floor (LSB size = VREF / 1024) sets the smallest detectable signal change. Use a low-impedance reference bypass capacitor and short analog input traces to minimize acquisition-time errors.

MAX160CPN+

MAX160CPN+ - 8-Bit 250 ksps SAR ADC | Maxim Integrated

The Maxim Integrated MAX160CPN+ is an 8-bit, single-input successive-approximation analog-to-digital converter with a 250 ksps conversion rate in an 18-pin PDIP package. It is a microprocessor-compatible precision ADC designed for acquisition systems that require parallel digital output, a single 5 V supply, and analog input capability associated with a -15 V ADC specification. An ADC converts a continuous analog voltage into a numeric value for processing, storage, or control. The MAX160CPN+ belongs to the SAR ADC hierarchy, where a successive-approximation register compares the input against a generated reference voltage during each conversion. Compared with flash and pipeline ADC architectures, this SAR approach combines a relatively simple conversion process with useful resolution and sampling speed for instrumentation, industrial measurement, and embedded data-acquisition systems. The principal specifications include 8-bit resolution, one analog input, a 250 ksps sampling rate, a parallel output interface, 5 V operation, and an 18-pin PDIP package. The + suffix identifies the lead-free ordering option within the MAX160 product family. Its 18-pin through-hole format also facilitates prototyping and replacement in legacy parallel-interface designs that do not use a compact surface-mount footprint. The single-input architecture concentrates performance on one conversion channel at a time. If the source changes rapidly between samples, the system must either use an external sample-and-hold circuit or synchronize acquisition timing so that the SAR process captures a stable input. The 250 ksps rating means the converter can complete approximately 250,000 conversions per second under its specified operating conditions. Typical uses include industrial process monitoring, legacy control-system data acquisition, laboratory measurement interfaces, and embedded equipment that reads a conditioned analog sensor signal. The parallel output allows the converted code to be read by compatible microprocessor or programmable-logic circuitry, while the 5 V supply simplifies integration with conventional digital systems. A critical design consideration is the analog front end. Input range, reference accuracy, conversion timing, acquisition time, and logic-level compatibility should be checked against the manufacturer datasheet before signal-chain design begins. Decoupling and grounding must follow the recommended application circuit to reduce switching transients and digital coupling into the conversion result. This product summary combines the MAX160CPN+ electrical identity, package details, sourcing context, pin-compatible family options, and application guidance into an engineering-focused reference for evaluating an 8-bit 250 ksps SAR ADC in a parallel-interface acquisition design.

The Analog Devices MAX160CWN+ is an 8-bit successive-approximation analog-to-digital converter with one single-ended input, 250 kSPS conversion throughput, an 8-bit parallel microprocessor-compatible output, and an 18-pin SOIC package. It is designed for cost-sensitive systems that require compact, direct digital sampling of an analog input. An ADC is an interface integrated circuit that converts a continuously varying voltage into a numeric code for processing, measurement, or control. The MAX160 belongs to the data-converter hierarchy within integrated circuits: ADC, data converter, mixed-signal IC, and semiconductor. Its internal successive-approximation architecture uses a binary search process to determine each 8-bit result, while its parallel output allows a microprocessor or other digital controller to read the converted value directly. Key characteristics include 8-bit resolution, one single-ended analog input, 250 kSPS operation, and a 4 microsecond conversion time. The MAX160 family is designed as a low-cost microprocessor-compatible converter, making it useful when the application does not require the resolution, throughput, or integrated reference features of a higher-performance ADC. The MAX160CWN+ is offered in an 18-pin SOIC package for conventional surface-mount PCB assembly. The MAX160 uses a successive-approximation conversion technique rather than pipelined, flash, or sigma-delta conversion. This architecture is appropriate for control and measurement loops that need straightforward conversion at moderate speed. The manufacturer identifies the MAX160 as a production CMOS device and describes the family as microprocessor compatible. The 4 microsecond conversion time corresponds to the stated 250 kSPS class of operation. Typical uses include industrial process monitoring, temperature and level sensing, consumer control panels, embedded instrumentation, and simple factory automation. Because the converter provides an 8-bit parallel interface, a design can connect its digital output bus to a microcontroller, programmable logic controller, or other parallel-input controller. An external reference and external input-conditioning network are normally required where the source signal does not already match the converter input range. The primary design consideration is signal conditioning. Keep the analog input within its permitted voltage range, provide suitable bypassing at the supply and reference pins, and account for source impedance when sampling. Board layout should keep the analog input trace short and isolated from high-current digital and switching paths to minimize conversion errors. This product page combines the manufacturer product information, distributor listings, package details, replacement cross-references, and practical design guidance. It also distinguishes the electrically similar MAX160EWN+ from variants that use different package or temperature-grade options, helping engineers evaluate replacement choices without assuming that every similarly named part is footprint-compatible.

It provides one single-ended input channel, an external reference, and parallel 8-bit output access, making it suitable for legacy microprocessor/microcontroller data-acquisition systems. An SAR ADC (Successive Approximation Register Analog-to-Digital Converter) is a type of data converter that uses a binary-search algorithm against an internal DAC and comparator to digitize an analog input in N clock cycles for N bits of resolution. SAR ADCs sit within the broader hierarchy of analog-to-digital converters -> data converters -> signal chain ICs -> semiconductor. They are valued for low latency, deterministic throughput, and excellent DC accuracy, which is why they dominate multiplexer-front-end, industrial-control, and precision-measurement designs. Key features include 8-bit resolution, 250 ksps maximum sampling rate, single +5 V supply operation, and CMOS low-power architecture. Built on a standard CMOS process, the MAX160EPN+ integrates a track-and-hold, successive-approximation register, precision comparator, and 8-bit DAC on-chip. The parallel interface allows direct connection to 8-bit microprocessors and microcontrollers without glue logic, and the single-ended input simplifies front-end signal-chain design. Typical applications include process control, instrumentation, battery-powered data loggers, sensor signal conditioning, and embedded microprocessor monitoring systems. The wide operating temperature window of 0°C to +70°C and through-hole PDIP package make it ideal for prototyping, breadboarding, and legacy system maintenance. When designing with the MAX160EPN+, ensure a stable external reference is provided to the REF pin for accurate conversions. Decouple VDD with a 0.1 µF ceramic capacitor close to the supply pin, and add a bulk capacitor for low-frequency noise rejection.

MAX160EWN+

MAX160EWN+ - 8-Bit 250 kSPS SAR ADC | Analog Devices

The Analog Devices MAX160EWN+ is an 8-bit successive-approximation analog-to-digital converter with one single-ended input, a 250 kSPS conversion rate, and a 4 µs conversion time in an 18-pin SOIC package. Designed for microprocessor-compatible acquisition, the device presents latched parallel output data and uses CMOS circuitry for low-cost embedded measurement systems. An ADC is an interface IC that converts an analog voltage into a digital code for processing, storage, display, or control. The MAX160 belongs to the SAR ADC category, within the broader analog-to-digital converter and data-converter IC hierarchy. SAR ADCs are useful where a sampled measurement must be acquired rapidly without the complexity and energy cost of continuous-time or higher-resolution converter architectures. The MAX160EWN+ provides 8-bit resolution, one single-ended input, and a 250 kSPS throughput. Its 4 µs conversion time is consistent with a successive-approximation architecture, while the microprocessor-compatible interface allows the converter to be handled as a memory location or I/O port without substantial external interfacing logic. The data outputs are latched, helping simplify connection to parallel-bus microprocessors and simple control systems. The part is specified in an 18-pin SOIC package and uses an external reference. Because the converter is single-input and single-ended, it is best suited to one-at-a-time acquisition rather than simultaneous sampling. Input conditioning, source impedance, reference stability, and acquisition timing remain important design considerations when interpreting the resulting 8-bit code. Typical uses include industrial process measurement, temperature-sensor interfaces, battery-rail monitoring, simple laboratory instrumentation, and embedded control systems with a parallel microprocessor bus. In each case, the ADC can provide a compact digital representation of a conditioned analog input while requiring relatively few support components. A key design practice is to place the converter close to the source or conditioning circuit and route the parallel data bus away from high-current switching nodes. The external reference must remain stable, and the application should account for conversion timing rather than treating the ADC as continuously sampled. The verified web sources provide no complete pin-by-pin electrical table, so unsupported details are marked as data needed instead of being inferred. This page consolidates verified manufacturer and distributor information, package characteristics, pricing references, source links, and application-oriented guidance. It also distinguishes confirmed facts from unavailable electrical details, helping engineers locate the datasheet and make a defensible sourcing decision without treating unverified parameters as guaranteed specifications.

The Maxim Integrated (now Analog Devices) MAX162ACNG+ is a complete high-speed CMOS 12-bit analog-to-digital converter (ADC) that integrates a successive-approximation register (SAR) architecture, an internal track-and-hold, a +2.5V reference, and a parallel microprocessor interface in a single 24-pin PDIP (NG) package. The MAX162ACNG+ delivers up to 308 kSPS conversion rate, accepts a unipolar 0V-to-+5V analog input range, and operates from a single +5V analog supply with a low 9 mW power dissipation at full throughput. The "A" grade offers ±1/2 LSB (max) INL/DNL linearity. An SAR ADC is a precision data converter which uses a binary-search successive-approximation register architecture to convert an analog input to a 12-bit digital word in N clock cycles (N = resolution in bits). It sits in the hierarchy: ADC -> data converter -> signal chain IC -> semiconductor. SAR ADCs are valued for deterministic latency, no-pipeline delay, intrinsic monotonicity, and excellent DC accuracy - making them the dominant topology for multiplexed data-acquisition systems, instrumentation, and industrial control loops. Key features of the MAX162ACNG+ include a maximum 1.75 us conversion time, an internal buried-Zener 2.5V reference (2.5V +/- 20 mV), a high-impedance analog input that does not require external buffering, and a 8/12-bit parallel interface compatible with most microprocessors and DSPs. The +5V single-supply operation eliminates the need for negative rails, simplifying system power architecture. Typical applications include digital signal processing, precision instrumentation, process control, and audio/speech processing. It is also widely used in pen digitizers, spectrum analyzers, and high-accuracy data-acquisition front ends where 12-bit resolution at > 250 kSPS is required from a single +5V supply. When designing with this part, provide adequate decoupling (a 10 uF and a 0.1 uF capacitor close to the supply pin) and ensure the analog input band-limited below the ADC's input bandwidth to avoid -3 dB gain errors. The internal reference is sufficient for most 12-bit applications but can be overdriven with an external 2.500V reference for higher-precision systems.

MAX162AENG+

MAX162AENG+ - 12-Bit 308ksps 5V Precision SAR ADC | Maxim Integrated

The Analog Devices Inc./Maxim Integrated MAX162AENG+ is a 12-bit, 308 ksps successive-approximation analog-to-digital converter (ADC) that operates from a single +5V supply and is housed in a 24-pin plastic DIP (PDIP-24) through-hole package. It provides one input channel with a precision on-chip track/hold amplifier, internal 4.096V reference, and a parallel microprocessor interface. The "+" suffix denotes the lead-free / RoHS-compliant version of the legacy MAX162 family, first introduced in the 1990s and still widely used in legacy industrial, instrumentation, and data-acquisition designs. A successive-approximation register (SAR) ADC is a type of analog-to-digital converter that uses a binary-search algorithm with an internal DAC to convert an analog input to a digital code, one bit at a time, in N clock cycles for N bits of resolution. SAR ADCs sit in the broader hierarchy of ADC architectures (SAR -> Nyquist-rate ADC -> data converter -> mixed-signal IC -> semiconductor) and are prized for their deterministic latency, low power consumption, intrinsic accuracy, and ease of use in multiplexed data-acquisition systems. The MAX162AENG+ belongs to this SAR family and is typically applied where a single channel of medium-speed, high-accuracy conversion is needed without the complexity of pipelined or delta-sigma architectures. Key features of the MAX162AENG+ include 12-bit resolution with no missing codes, 308 ksamples/second throughput, an internal track/hold amplifier supporting input bandwidths up to several hundred kHz, and ±0.5 LSB integral nonlinearity (INL) typical. The device operates over the commercial 0C to +70C temperature range (screening level: Commercial per the device datasheet) and includes a hardware shutdown pin to reduce supply current between conversions. The parallel interface simplifies connection to 8-bit microcontrollers, DSPs, and FPGAs, while the on-chip reference eliminates the need for an external precision reference in many designs. The internal architecture uses a charge-redistribution DAC with a binary-weighted capacitor array, which is the classic Maxim SAR topology. Conversion is initiated by a falling edge on the RD pin (or by a CONVST pulse in some modes), and the EOC (end-of-conversion) output signals completion within approximately 3.3 us at full speed. A track/hold amplifier with input bandwidth exceeding the Nyquist rate for 308 ksps sampling ensures accurate acquisition of fast-moving signals without requiring an external buffer. Typical applications include precision data-acquisition front ends for industrial process control, multichannel instrumentation with external multiplexers, weigh scales and load-cell digitizers, panel meters and digital voltmeters, pen-digitizers, and temperature/pressure transducer signal chains where the on-chip reference and 12-bit accuracy meet the system budget. Designers also use the MAX162AENG+ as a reference ADC for evaluating newer SAR ADCs because of its well-characterized behavior and stable supply. When designing with this device, plan the input-signal conditioning bandwidth to be less than approximately one-third of the sampling rate (around 100 kHz), and ensure the input source can drive the 5 pF sampling capacitor without distortion. Power-supply decoupling with a 10 uF tantalum plus 0.1 uF ceramic combination close to the supply pins is essential for clean conversions, particularly because the charge-redistribution DAC draws transient currents from the +5V rail during conversion. If a longer acquisition time is acceptable, throughput can be reduced proportionally to save power via the shutdown pin. This page synthesizes distributor pricing, drop-in pin-compatible alternatives in the same 24-PDIP footprint, and practical design notes not found in the manufacturer datasheet, helping engineers both specify the MAX162AENG+ in new designs and find cross-brand drop-in replacements for end-of-life or hard-to-source ADC slots on legacy boards.

MAX162BCNG+ - 12-Bit 3µs SAR ADC, 24-PDIP | Maxim Integrated

The Analog Devices (formerly Maxim Integrated) MAX162BCNG+ is a complete 12-bit analog-to-digital converter (ADC) that combines high-speed successive-approximation (SAR) conversion, low power consumption, and an on-chip buried-zener reference in a single 24-pin PDIP through-hole package. The MAX162 family achieves a 3 µs conversion time while the pin-compatible MX7572 variant offers 5 µs or 12 µs conversion options. Operating from +5 V (digital) and -12 V to -15 V (analog) supplies, the MAX162BCNG+ integrates a track-and-hold amplifier, voltage reference, clock, and parallel microprocessor interface, eliminating the need for external active components beyond decoupling capacitors. An SAR ADC is a successive-approximation-register analog-to-digital converter that uses a binary-search algorithm to digitize an analog input in N clock cycles for N-bit resolution. SAR ADCs sit in the data-converter hierarchy between flash converters (fastest, lowest resolution) and sigma-delta converters (highest resolution, slowest). They are the workhorse of mid-speed, mid-resolution industrial instrumentation, motor control, and process control applications where both speed and precision matter. The MAX162BCNG+ provides 12-bit resolution with no missing codes, a built-in buried-zener reference delivering low drift and low noise, and a track-and-hold front end that handles input bandwidths well beyond the Nyquist limit of its 3 µs conversion rate. The parallel interface simplifies connection to standard 8-bit and 16-bit microprocessors without glue logic, and the commercial 0 °C to +70 °C operating range targets bench-test, factory-floor, and embedded industrial designs. Typical applications include digital signal processing front ends, precision industrial process control loops, high-speed data acquisition boards, and audio digitizing systems. The on-chip reference also makes the part attractive for portable instrumentation where external reference count is undesirable. The MX7572 superset pin compatibility offers designers a software-compatible upgrade path to longer integration or slower conversion for cost-sensitive designs. When laying out a MAX162BCNG+ circuit, place 0.1 µF and 10 µF decoupling capacitors within 5 mm of each supply pin and keep analog and digital grounds separated back to a single-point star ground at the ADC. Avoid routing digital outputs directly under the analog input pin to prevent digital-noise coupling into the high-impedance sample-and-hold node.

MAX162BENG - 12-Bit 3µs SAR ADC, 24-PDIP | Maxim Integrated

The Analog Devices (formerly Maxim Integrated) MAX162BENG is a 12-bit successive-approximation analog-to-digital converter that delivers a 3 µs conversion time on a single 5 V analog supply, housed in a 24-pin plastic DIP through-hole package. The part combines a high-speed 12-bit ADC core, an on-chip wideband track/hold, and a buried-zener reference with low drift and low noise performance, while drawing only a few milliwatts from a single +5 V (or ±5 V analog with +5 V digital) supply rail. What is an ADC? An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that samples a continuous analog input voltage and converts it into a discrete digital code. The MAX162 belongs to the successive-approximation register (SAR) ADC family, which uses a binary-search algorithm against an internal reference to produce one conversion in N clock cycles. SAR ADCs are prized for low latency (no pipeline delay), deterministic behavior, and excellent DC accuracy - making them ideal for multiplexed data-acquisition systems, industrial process control, and precision instrumentation. Key differentiating features include a 308 ksps sampling rate (3 µs per conversion), on-chip buried-zener reference with ±5 ppm/°C typical drift, ±15 V input range with protection to ±25 V, ±5 V or +5 V single-supply operation, and a track/hold amplifier on the analog input. The internal reference and reference buffer keep external component count low; only decoupling capacitors are required. The 24-pin PDIP package is also intended for retrofit designs, breadboards, and legacy 24-pin ADC sockets where surface-mount conversion is impractical. Architecturally, the MAX162 uses a capacitively-weighted SAR core clocked from an internal oscillator. Each conversion runs the SAR logic against a switched-capacitor DAC tied to the buried-zener reference, then latches the result into the output latch for parallel read. Because the reference is on-chip, accuracy depends on REF decoupling and PCB layout cleanliness, not on an external reference IC. Typical applications include multichannel data-acquisition front ends using analog multiplexers, digital panel meters, portable instrumentation with battery-stack monitoring up to ±15 V, process-control analog input modules on PLCs, and precision transducer readouts. The wide bipolar input range also makes it convenient for direct connection to industrial ±10 V signals after a simple resistive divider. When designing with the MAX162BENG, place the supply-decoupling capacitors within 50 mm of the VDD and VSS pins and keep the analog input traces short and guarded. Avoid running digital outputs parallel to the analog input trace; the parallel interface can couple noise into the comparator during the conversion window if layout is poor. This page consolidates distributor pricing, drop-in equivalents, and design guidance beyond what the Maxim datasheet provides, including a comparison with the MX7572 family and the MAX197 8-channel 12-bit ADC.

It operates from a single +5 V supply and draws only a few milliwatts during conversion. An SAR ADC is a type of analog-to-digital converter that uses a binary-search algorithm implemented with a capacitive DAC and a comparator. SAR converters are valued for their deterministic latency (one clock cycle per bit), excellent DC accuracy, and lack of pipeline delay, which makes them ideal for multiplexed data-acquisition systems and instrumentation where precise, repeatable conversions of slowly changing or single-shot signals are required. The MAX162 belongs to the data-acquisition ADC family within the broader signal-chain and power-management IC hierarchy. Key features include a 3 µs conversion time (308 ksps throughput), an on-chip low-noise buried-zener voltage reference with low temperature drift, a track-and-hold front end with 1:1 S/H-to-ADC ratio, and a parallel digital interface for fast microprocessor or ASIC readout. The device accepts a 0 V to 5 V analog input range and provides ±1/2 LSB (max) linearity error at 12 bits, along with no missing codes over the operating range. Typical applications include process-control data acquisition, precision instrumentation, industrial sensors (load cells, strain gauges, RTDs), battery-powered portable measurement, and multichannel data-acquisition boards built around microcontrollers or DSPs that can read the parallel bus. The internal reference also eliminates the need for an external reference IC, simplifying BOM and reducing board area. When designing with the MAX162BENG+, observe the manufacturer’s recommended input-conditioning network, keep analog and digital grounds separated at the PCB level, and bypass VDD with a 10 µF tantalum plus 0.1 µF ceramic capacitor pair to suppress reference noise.

MAX163BCWG+

MAX163BCWG+ - 12-Bit ADC with Track-and-Hold | Analog Devices

The Analog Devices MAX163BCWG+ is a CMOS 12-bit analog-to-digital converter with integrated track-and-hold, operating on a single +5V analog supply and a -5V (or larger negative) VSS supply with separate analog and digital ground pins. It supports a ratiometric or external reference input and converts at 73 kS/s with a tracking bandwidth that preserves full-scale settling for fast transient signals at the analog input. A successive-approximation ADC (SAR ADC) is a converter architecture that uses a binary search through an internal capacitive or resistive DAC to converge on the input voltage in N clock cycles, where N is the resolution in bits. The MAX163 family uses a half-flash or full successive-approximation topology with self-calibrated charge redistribution capacitors, providing 12-bit accuracy with no missing codes. Within the data-conversion hierarchy, SAR ADCs sit between delta-sigma ADCs (which deliver higher resolution at lower speeds) and flash ADCs (which deliver the highest speed at low resolution). Key features of the MAX163 include 12-bit resolution with no missing codes (INL +/- 0.5 LSB), a track-and-hold input front end (not dependent on input signal rise/fall rate), an internal buried-zener reference trimmed to 4.096V, and support for bipolar input signal ranges when using VSS and external scaling. Its 24-pin wide-body SOIC (SO-24, CWG suffix) package exposes separate AGND and DGND pins so a Star grounding topology can be implemented on the PCB to suppress digital-switching noise from coupling back into the analog input. Typical applications include process-control data acquisition front ends, instrumentation front-end digitizers, multiplexed analog input subsystems for PLCs, motor-control current/voltage monitoring channels, and any place where a wide input range, moderate throughput, and 12-bit precision are needed from a single board. It is well-suited to industrial analog front ends because the bipolar-input design accepts 0 to 12V or +/-5V ranges. A key design consideration is the supply-decoupling network: a 10uF tantalum and a 0.1uF ceramic at each supply pin, plus separate analog and digital ground returns joining at one star point at the AGND pin, are essential to extract full 12-bit performance in noisy environments. Using a single supply without VSS disables bipolar operation and confines the input to 0-5V (ratiometric with VREF).

It is a commercial-temperature-grade (0C to 70C) successive-approximation ADC designed for embedded data-acquisition systems requiring low-power, single-supply operation. What is a SAR (Successive Approximation Register) ADC? A SAR ADC is a type of analog-to-digital converter that uses a binary-search algorithm against an internal precision DAC to resolve an input voltage in N conversion cycles, producing N-bit output. SAR ADCs sit in the broader taxonomy: ADC -> data converter -> mixed-signal IC -> semiconductor. They are valued for medium resolution (8 to 16 bits), deterministic latency, low power, and ease of use compared to delta-sigma or pipeline architectures. The track-and-hold front-end allows accurate conversion of fast-changing signals by holding the input constant during the conversion cycle. Key features of the MAX163BCWG+T include 12-bit resolution, integrated track-and-hold, single +5V analog supply operation, low power CMOS construction, and a standard SO-24 wide surface-mount footprint. The +T suffix indicates factory tape-and-reel packaging for high-volume automated assembly. The device uses a capacitive-charge redistribution DAC core with auto-calibration logic, providing excellent DC accuracy and low integral nonlinearity. Its parallel microprocessor interface simplifies connection to microcontrollers and DSPs without requiring a serial clock generator. Typical applications include process control and instrumentation, data loggers, pen-trace plotters, patient monitoring, panel meters, and embedded industrial controllers. Designers choose the MAX163 family for its low power, simple parallel interface, and DIP/SO legacy compatibility for new and replacement designs. When designing with this device, ensure the analog input does not exceed the supply rails; add anti-alias filtering at the input; and provide adequate decoupling (typically 10uF bulk + 0.1uF ceramic) close to the supply pin to ensure low-noise conversions.

MAX164BCNG - 12-Bit 100ksps SAR ADC with T/H | Maxim Integrated

The Maxim Integrated (Analog Devices) MAX164BCNG is a 12-bit resolution, 100 ksps successive-approximation analog-to-digital converter (ADC) with an integrated track-and-hold stage and on-chip reference, housed in a 24-pin plastic DIP (PDIP-24) through-hole package. The single-channel device operates from a single +5 V supply (with analog input span of 0 V to +5 V unipolar, or ±5 V bipolar with external resistor network), delivers 12-bit parallel output data, and dissipates typically under 30 mW during continuous conversion. The 'B' speed grade defines 100 ksps minimum throughput and the 'C' commercial temperature grade of 0 °C to +70 °C. What is a SAR ADC: a Successive Approximation Register ADC is a Nyquist-rate converter that performs one bit-trial per clock, comparing the held input against an internal binary-weighted DAC. SAR ADCs trade the speed of flash converters for much lower power and die area, making them the dominant architecture for 8-to-16-bit industrial and instrumentation sampling in the 1 ksps to 1 Msps range. The track-and-hold front-end eliminates the need for an external buffer amplifier and guarantees accurate sampling of fast-moving signals at the full 100 ksps rate. Key features include ±½ LSB linearity (typical), an internal 5.0 V buried-zener reference with ±1.5 % initial accuracy, a hardware shutdown mode that drops quiescent current to under 100 µA for battery-powered designs, and a standard microprocessor-compatible parallel interface. The device connects directly to 8-bit and 16-bit buses without external glue logic. Its single +5 V analog supply and unipolar analog input make it a natural fit for legacy industrial front-ends. The MAX164BCNG uses a charge-redistribution DAC array and CMOS logic on the same die, with separate analog (V+ and AGND) and digital (VDD and DGND) supply pins to reduce digital switching noise coupling into the conversion result. The on-chip reference may be overdriven by an external reference when system calibration demands tighter absolute accuracy. Typical applications include industrial process control data acquisition boards, portable instrumentation and digital panel meters, multiplexed 4-20 mA loop digitizers, medical telemetry front-ends, and legacy drop-in replacements for older Maxim/Analog Devices 12-bit ADC sockets. Through-hole PDIP also simplifies breadboard and educational laboratory prototyping. When designing with the MAX164BCNG, place 0.1 µF ceramic bypass capacitors close to both the analog and digital supply pins and ensure AGND and DGND connect at a single point near the IC. Avoid driving the analog input with source impedances above 2 kOhm without an external buffer, as the track-and-hold settling time will degrade.

MAX164BCWG - 12-Bit CMOS ADC with T/H, 100ksps | Maxim Integrated

The Maxim Integrated MAX164BCWG is a 12-bit successive-approximation CMOS analog-to-digital converter (ADC) with an integrated track-and-hold amplifier, single +5V (or ±5V) supply operation, and 100 ksps sampling rate, housed in a 24-pin wide-body SOIC package. According to the Maxim datasheet, the part accepts a single-ended analog input through an input T/H stage and converts it into 12 parallel digital outputs that can be read with 8-bit access timing for easy interface to microcontrollers and digital signal processors. An ADC (analog-to-digital converter) is a mixed-signal IC that converts continuous-time analog voltages into discrete digital codes for downstream processing. The MAX164BCWG uses successive-approximation register (SAR) architecture, which combines a capacitive charge-redistribution DAC with a precision comparator. Within the broader semiconductor taxonomy, ADCs sit under data converters -> mixed-signal ICs -> analog ICs -> semiconductors. Track-and-hold behavior makes this ADC suitable for signals that change faster than the conversion time, because the T/H stage snapshots the input at the start of conversion and holds it constant while internal switch capacitors settle. Key differentiating specifications include ±1 LSB integral and differential nonlinearity (INL/DNL), a single +5V supply rail option, an internal reference option, and low power consumption. The internal 2.5V reference allows operation from a single +5V rail without external reference components, while the unipolar/bipolar input range can be software-selected through external pin connection. The 8-bit access mode permits byte-by-byte readout of the 12-bit result via a single 8-bit data port, which simplifies the interface to 8-bit microcontrollers. The MAX164BCWG architecture uses a charge-redistribution SAR core in which binary-weighted capacitor arrays form both the input sampling network and the reference DAC. The input T/H stage fully settles within one acquisition-time clock, after which the internal comparator performs the 12-bit binary search across 12 successive clock cycles. Sampling rate scales with the system clock frequency; the production datasheet specifies full 100 ksps throughput with proper signal decoupling. Typical applications include digital signal processing front ends, audio digitization and instrumentation, multiplexed data-acquisition systems with sample-and-hold stages, process-control I/O modules, and battery-powered or portable data loggers that require single-supply 12-bit conversion. The combination of internal reference, T/H, and byte-mode readout also makes the part useful in motor-control feedback loops where 12-bit resolution is sufficient. When designing with this part, ensure analog and digital grounds are joined only at the AGND/DGND pin near the IC. Decouple the +VCC rail with a 0.1 µF ceramic capacitor within 5 mm of the supply pin and add a 10 µF bulk capacitor on the same rail. The analog input source impedance should stay below the value specified in the datasheet acquisition-time plot to avoid losing dynamic range; high-impedance sources require an external buffer amplifier.

The /883B suffix designates the MIL-PRF-38535 QML processing flow, qualifying the part for -55°C to +125°C military temperature operation with hermetic ceramic packaging suitable for harsh-environment and defense applications. The converter features a built-in buried-zener reference (typ. 25 ppm/°C drift) plus an input multiplexer and a serial or parallel interface option, condensing a precision 12-bit signal chain into a single through-hole IC. Background: An ADC (analog-to-digital converter) is a data-acquisition mixed-signal IC that converts real-world analog voltages into discrete digital codes for processing by microcontrollers, DSPs, or FPGAs. Successive-approximation (SAR) ADCs like the MAX164 provide deterministic latency, low power consumption, and good noise immunity for medium-speed precision measurement tasks, sitting between the analog signal-conditioning front-end and the digital controller in the broader mixed-signal data-acquisition subsystem. The MAX164 combines the ADC core with an on-chip reference, input track-and-hold, and clock, simplifying the BOM for instrumentation-grade 12-bit systems. Key features include 12-bit resolution with ±0.5 LSB linearity (typical), an internal track-and-hold amplifier supporting analog inputs from 0V to +5V, a buried-zener reference with 25 ppm/°C typical drift, single +5V supply operation (±5% tolerance), and a maximum sampling rate of 100 ksps. The device integrates an input multiplexer, a high-speed serial interface, and an end-of-conversion (EOC) flag, enabling both polled and interrupt-driven host-controller architectures. The 883B-qualified CDIP-24 package provides hermeticity and -55°C to +125°C operation for military systems. The MAX164 is built on a low-power CMOS mixed-signal process. The SAR architecture guarantees 1.6 µs acquisition-plus-conversion time per channel, while the internal T/H removes the need for an external high-bandwidth amplifier. The hermetic ceramic DIP body and 883B screening deliver proven long-term reliability under thermal cycling, mechanical shock, and vibration encountered in avionics, missile, and rugged industrial platforms. Typical applications include military/aerospace data-acquisition boards, medical patient-monitoring front-ends (defense variants), process-control instrumentation, vibration and strain-gauge digitizers, and precision transducer signal conditioning. Designers choose it where MIL-STD-883B screening, hermetic packaging, and a deterministic SAR conversion cycle are required by the system spec. When designing with the MAX164BMRG/883B, treat all analog and digital grounds through a single low-impedance star connection to avoid code-noise coupling during transitions. Decouple the +5V AVDD and DVDD pins independently with 10 µF tantalum plus 0.1 µF ceramic capacitors mounted within 5 mm of each supply pin.

The internal reference eliminates external reference components while maintaining tight absolute accuracy. The MAX164 family is a member of the data-acquisition IC hierarchy: ADC -> successive-approximation ADC -> data converter -> signal-chain IC -> semiconductor. A successive-approximation ADC uses an internal DAC and comparator to binary-search the input voltage, achieving an excellent balance of speed, resolution, and low power consumption for 12-bit applications. Compared with flash ADCs, SAR converters offer far lower power at moderate speeds; compared with integrating ADCs (e.g., dual-slope), they offer much higher throughput. Typical applications include industrial process-control data acquisition, portable instrumentation and battery-powered measurement, multiplexed data-logging systems, pen-tablet digitizers, robotics sensor interfaces, and embedded control loops requiring 12-bit absolute accuracy. The parallel interface simplifies connection to standard microprocessors and DSPs without external glue logic. When designing with this device, place a 10uF decoupling capacitor close to VDD and AVCC pins, and use the recommended bypass network for the reference pins. The internal reference is trimmed but degrades slightly when sourcing external load current; ensure REF decoupling is sized accordingly.

The Analog Devices / Maxim Integrated MAX164CMRG/883B is a monolithic CMOS 12-bit analog-to-digital converter (ADC) with a built-in track-and-hold amplifier and an internal 2.5V reference, qualified to MIL-STD-883B and packaged in a 24-pin ceramic DIP (CDIP-24). It accepts a 0V to 5V unipolar analog input and delivers 100 ksps throughput from a single +5V (analog) and +5V/-12V to -15V (digital) supply configuration. Background: A successive-approximation register (SAR) ADC is one of the canonical ADC architectures, sitting alongside flash, pipeline, and sigma-delta in the data-converter taxonomy. SAR ADCs use an internal DAC and comparator to binary-search the analog input against a reference, producing one N-bit code per conversion cycle. Their strength is excellent DC accuracy, deterministic latency, and low power consumption at moderate sample rates, which is why they dominate industrial, instrumentation, and military embedded systems where precise DC measurements and predictable response are required. Key features of the MAX164CMRG/883B include 12-bit resolution, an integral non-linearity (INL) of +/-1 LSB maximum, and an internal 2.5V reference with +/-1.5% tolerance. The device exposes a parallel data interface for direct connection to microprocessors, and the built-in track-and-hold eliminates the need for an external sample-and-hold stage. The /883B suffix signifies MIL-STD-883B qualification for high-reliability and aerospace/defense applications. The MAX164CMRG/883B is fabricated on a low-power CMOS process and uses a charge-redistribution DAC array that delivers true 12-bit performance without missing codes over the full military temperature range. The internal reference simplifies board layout by removing the external reference IC and bypass network, while the wide input bandwidth of the front-end T&H allows the converter to capture fast transient signals at full throughput without a separate buffer. Typical applications include data acquisition systems in industrial control, precision instrumentation front-ends, military and aerospace telemetry subsystems, automatic test equipment (ATE), and process-control signal-conditioning modules. Designers choose this part when a 12-bit, 100 ksps SAR converter with an internal reference and MIL-spec screening is required in a through-hole footprint. When designing with the MAX164CMRG/883B, note that the digital supply accepts a negative rail (-12V to -15V), which is uncommon for modern TTL-compatible SAR parts. By verifying that your digital logic levels match the MAX163B family, this part can replace older 12-bit ADC front-ends without redesign. Designers should follow the analog and digital ground separation recommendations in the datasheet.

MAX165ACWN - 5µs 8-Bit ADC with Track/Hold | Maxim Integrated

The Maxim Integrated MAX165ACWN is a CMOS, µP-compatible, 8-bit analog-to-digital converter with a 5 µs conversion rate, integrated track/hold, and an internal 2.46 V precision reference, housed in an 18-pin SOIC wide-body (0.295 inch / 7.50 mm) package. An 8-bit ADC (analog-to-digital converter) is a data-acquisition building block that quantizes an analog input signal into 256 discrete digital codes for processing by a microcontroller, microprocessor, or DSP. ADC chips fall within the broader data-converter family (ADC/DAC) and bridge the analog signal-chain and digital logic domains. Successive-approximation-register (SAR) ADCs such as the MAX165 provide deterministic latency and a single-shot conversion, making them ideal for multiplexed instrumentation and process-control front ends. Key features include a 5 µs typical conversion time (200 ksps throughput), a built-in track/hold amplifier, an on-chip 2.46 V reference (15 mA drive capability), and a parallel µP-compatible interface. The MAX165 operates from ±5 V supplies (or +5 V / -12 V), accepts 0 V to 5 V unipolar or ±5 V bipolar analog inputs, and provides three-state latched outputs that interface directly to 8-bit data buses. Operating temperature spans 0°C to +70°C (C-grade). Internally, the MAX165 uses a charge-redistribution SAR architecture with a laser-trimmed thin-film resistor ladder, which delivers monotonicity over the full operating range and eliminates the need for an external sample-and-hold in most applications. The internal reference uses a buried-zener topology, providing low temperature drift and excellent line regulation. Typical applications include process-control and industrial data acquisition, portable instrumentation, panel meters and digital voltmeters, embedded µP/µC analog input modules, and precision threshold-detection circuits. The wide SOIC package and standard control signals (CS, RD, BUSY) ease integration with 8051, 68HC11, Z80, and similar 8-bit controllers. When designing with the MAX165, take care to bypass the analog supply with a 10 µF tantalum plus 0.1 µF ceramic capacitor close to the AVDD pin, and decouple the digital supply separately. The reference output (REF) requires a 4.7 µF bypass to ground for stable operation - omitting this capacitor is a common cause of degraded linearity.
