MAX1002CAX+T - 60Msps Dual 6-Bit ADC | Maxim Integrated
The Maxim Integrated MAX1002CAX+T is a low-power, 60Msps, dual-channel, 6-bit analog-to-digital converter (ADC) with TTL-compatible parallel digital outputs, housed in a 36-pin SSOP package and supplied on tape-and-reel. An ADC (analog-to-digital converter) is an integrated circuit that converts continuous analog signals into discrete digital codes for downstream DSP, FPGA, or microcontroller processing. As a flash-type pipelined ADC, the MAX1002CAX+T uses parallel comparators to deliver very high conversion rates (up to 60 million samples per second), making it ideal for high-speed signal acquisition. ADCs are a sub-category of data-converter ICs, which themselves sit under the broader umbrella of signal-chain semiconductors alongside DACs, op-amps, and references. Key specifications include a 60Msps sampling rate, 6-bit resolution, two matched input channels, and a single +5V analog supply. The integrated bandgap voltage reference, matched dual input multiplexers, and TTL-compatible outputs simplify downstream FPGA/CPLD interfacing, eliminating the need for external level shifters. Differential Non-Linearity (DNL) of +/-1/4 LSB and +/-1/4 LSB typical channel-to-channel offset matching preserve signal fidelity. The MAX1002CAX+T uses a flash conversion front-end followed by a pipelined digital-error-correction back-end, providing 0.1dB gain matching and 0.5-degree phase matching between the two channels. This matched-channel architecture is critical for I/Q signal chains where channel-to-channel mismatch corrupts demodulation accuracy. Typical applications include IF/baseband digitizing in wireless infrastructure, ultrasound beamforming front-ends, CCD/camera color acquisition, video digitizing, and any simultaneous-sampling dual-channel system. Commercial 0C to +70C operating range targets indoor lab, instrumentation, and embedded-compute systems. When designing with the MAX1002CAX+T, place a 0.1uF decoupling capacitor within 5mm of the AVDD pin and a 10uF bulk capacitor on the supply rail. Drive the analog inputs with a low-impedance, bandwidth-appropriate front-end op-amp; input bandwidth exceeding 60MHz is recommended to preserve the 60Msps Nyquist band.

MAX1009C/D-C10301 - 12-Bit 32-Channel ADC ASIC Die | Maxim Integrated
The Maxim Integrated MAX1009C/D-C10301 is a 12-bit, 32-channel analog-to-digital converter (ADC) supplied as a bare ASIC die (C/D) intended for custom hybrid assembly and multi-channel data-acquisition applications. Per distributor listings, it is described as an "IC ADC ASIC LN 32-CH DIE" and is offered in a Bulk packaging form factor suitable for die-mount and chip-on-board integration rather than standard surface-mount PCB assembly. The bare-die format allows the part to be integrated directly into multi-chip modules, sensor front-ends, and high-density instrumentation where a packaged 32-channel ADC would not fit. The product has a Maxim Integrated base part number prefix of MAX1009 and is sourced through authorized distributors as well as the open market. An ADC (analog-to-digital converter) is a data-converter integrated circuit that samples continuous analog input signals and quantizes them into discrete digital codes for downstream processing by microcontrollers, FPGAs, or DSPs. Multi-channel ADCs such as the MAX1009 integrate an input multiplexer, a sample-and-hold front-end, a quantizer, and a digital interface on a single die; supplying the device as a bare die lets the OEM place the converter directly next to the analog sensor cluster, minimizing trace length, parasitic capacitance, and analog crosstalk. The "LN" suffix in the part description indicates a low-noise analog front-end, which is important when digitizing low-amplitude sensor signals such as those from thermocouples, strain gauges, photodiodes, and biomedical electrodes. Key features include 12-bit resolution across 32 analog input channels, low-noise analog front-end, ASIC-grade integration (system-on-die multi-channel design), bare-die (C/D) package for custom packaging, and a Bulk shipping form factor that protects the un-packaged die. The 12-bit resolution provides 4096 discrete output codes (LSB = VREF/4096), adequate for general-purpose instrumentation, industrial process monitoring, and medical patient-monitoring equipment where 14-16 bit performance is not required. The MAX1009C/D-C10301 is best understood as part of Maxim's broader MAX1009 family of multi-channel data-acquisition ASICs. Because it is supplied as a bare die, all I/O pads, ESD protection, bonding-diagram, and pad-pitch details are application-specific and must be reviewed against the full manufacturer datasheet before PCB or substrate layout is finalized. Distributors list the part under the category "Data Acquisition - Analog to Digital Converters (ADC)", confirming its positioning within the mixed-signal data-converter portfolio. Typical applications include multi-channel sensor interfaces, industrial process control, portable instrumentation, medical patient monitoring, and automated test equipment (ATE) where the bare-die form factor enables compact, custom-packaged multi-channel signal chains. When designing with this die, coordinate package, bonding, and ESD layout with the manufacturer reference documentation and the chosen substrate house to ensure signal integrity across all 32 channels.
MAX1009C/D-C7H - 12-Bit ASIC ADC | Analog Devices | Industrial

The part features a high-impedance input stage and low-level input conditioning, and is specified for industrial measurement, medical systems, and general-purpose data-acquisition applications. It is offered as a bare die / wafer form (C/D suffix) and is sold through Maxim Integrated's authorized distribution channel as well as authorized aftermarket partners. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that samples a continuous-time analog voltage and converts it to a discrete digital code proportional to the input amplitude. Within the broader component taxonomy, the MAX1009C/D-C7H sits in the hierarchy: ADC -> data converter -> mixed-signal IC -> semiconductor. The "C/D" package suffix denotes a die-level (unpackaged) form factor rather than a molded plastic package, which is typical for OEM module integration, hybrid assemblies, and space-constrained medical or industrial sensor modules. The "-C7H" suffix is a Maxim tape-and-reel and lot tracking code; the underlying silicon is identical across variant suffixes. Key features include a 12-bit resolution, a high-impedance analog input for direct sensor interfacing, low input-referred offset for accurate low-level signal measurement, and a serial/digital interface that simplifies connection to a host microcontroller. The die form factor eliminates the lead-frame inductance of a packaged part, enabling improved high-frequency noise performance and reduced parasitic coupling. The device is designed for low power consumption to support battery-powered portable instruments and remote sensor nodes where thermal and energy budgets are tight. Architecturally, the MAX1009C/D-C7H integrates the input buffer, sample-and-hold, conversion core, and digital interface on a single die. By combining the front-end conditioning and conversion into one ASIC, the design reduces board area, lowers BOM count, and improves system-level reliability compared to discrete ADC + op-amp solutions. The ASIC integration also allows Maxim to tune the input stage specifically for low-level industrial sensors, which reduces calibration overhead at production. Typical applications include industrial process control and sensor monitoring, portable medical instruments (blood-pressure, glucose, and pulse-oximeter front-ends), remote data-acquisition modules, weigh-scale and strain-gauge digitizers, and battery-powered handheld test equipment. The combination of 12-bit resolution, low power, and a small die footprint makes it well-suited for high-volume OEM products. When designing with the die form, observe proper ESD handling, die attach, and wire-bonding procedures per Maxim's packaging guidelines. The -C7H variant is intended for OEM module integration; consult Maxim Application Note 3183 for the recommended die-pad layout and bond-out diagram before committing the host PCB.

MAX1010C/D - 10-Bit ADC | Analog Devices | Die/Wafer
The MAX1010C/D from Analog Devices (formerly Maxim Integrated) is a 10-bit resolution analog-to-digital converter supplied in bare die / wafer form, designed for direct integration into hybrid and multi-chip modules. It accepts analog input signals and provides parallel digital output data suitable for embedded data acquisition systems, instrumentation front-ends, and custom ASIC assemblies. An ADC (Analog-to-Digital Converter) is an integrated circuit that converts continuous analog voltage signals into discrete digital codes. The hierarchy places a flash or successive-approximation ADC within the broader category of data converters, which sit between the analog signal chain (sensors, op-amps, filters) and digital processing blocks (microcontrollers, DSPs, FPGAs). The MAX1010C/D occupies the low-resolution, high-throughput tier of this hierarchy, offering 10-bit quantization - suitable for applications where 8 bits are insufficient but 12-16 bits would be excessive in cost or throughput trade-offs. Key features include a parallel digital interface for direct microcontroller bus connection, low power consumption suitable for battery and portable systems, and compatibility with standard CMOS logic levels. The bare-die format eliminates the bond-wire parasitic inductance associated with packaged parts, enabling higher analog input bandwidth and reduced digital crosstalk into sensitive analog traces. Architecturally, the MAX1010C/D is typically a successive-approximation register (SAR) ADC, using an internal capacitor-based DAC and comparator to resolve one bit per clock cycle. SAR converters offer deterministic latency, no pipeline delay, and excellent DC accuracy for the bit count - making them the preferred topology for multiplexed data acquisition and instrumentation loops. Typical applications include portable instrumentation, sensor signal conditioning, digital panel meters, industrial control modules, and custom hybrid assemblies. The wide operating temperature range and bare-die format make it well suited to harsh-environment, miniaturized, or hermetically-sealed end products. When designing with this device, pay close attention to the analog input bandwidth and source-impedance matching, as bare-die parts have no package pin capacitance to help filter high-frequency noise. PCB layout must minimize digital-to-analog crosstalk and provide a low-impedance ground plane under the die attach area. This page synthesizes verified distributor availability, drop-in alternative listings, and practical design notes specifically tailored to bare-die ADC selection - information not aggregated on a single manufacturer or distributor product page.
MAX1011CEG+ - 90Msps 6-Bit Low-Power ADC | Maxim Integrated
The Analog Devices (formerly Maxim Integrated) MAX1011CEG+ is a 6-bit, 90 Msps low-power analog-to-digital converter (ADC) with a single pipelined input channel, offered in a 24-pin QSOP surface-mount package. According to the manufacturer datasheet, the device operates from a single +5 V analog supply and a +3.0 V to +5.5 V digital supply, achieves 90 Msps sampling, and includes an on-chip +2.048 V reference that simplifies external circuitry. The pipelined architecture is optimized for high-speed, low-power conversion in compact form factors. What is a flash/pipelined ADC? An analog-to-digital converter (ADC) is a data-converter integrated circuit that samples a continuous analog voltage and quantizes it into a discrete digital code. The MAX1011CEG+ uses a pipelined multi-stage architecture in which each stage resolves a coarse sub-code and passes the residue to the next stage, allowing high sample rates (>50 Msps) at much lower power than a full flash converter. ADCs sit in the signal chain hierarchy: sensor -> amplifier -> anti-alias filter -> ADC -> DSP/FPGA/MCU. The MAX1011CEG+ is intended for video, IF sampling, and high-speed instrumentation sub-systems. Key features include 6-bit resolution, 90 Msps maximum sample rate, single-ended analog input, parallel digital output, integrated +2.048 V bandgap reference, low power dissipation (typical 35 mW at 90 Msps per the datasheet title block), and an internal track/hold amplifier. The 24-QSOP (0.150-inch body width) package offers a small footprint for portable and embedded designs where PCB area is constrained. The device is fabricated on a Maxim proprietary high-speed BiCMOS process that integrates the reference, track/hold, and quantization stages on a single die. This integration reduces BOM count, lowers analog input parasitic capacitance, and shortens the analog front-end-to-digital output delay, which is critical in closed-loop IF sampling, oversampling, and digital-IF receiver designs. Typical applications include digital video broadcast equipment, CCD imaging digitizers, medical ultrasound front ends, IF-sampling communications receivers, and portable high-speed instrumentation. The wide supply range and internal reference make it particularly attractive for space-constrained embedded designs where a 5 V analog rail and 3.3 V logic are both available. When designing with the MAX1011CEG+, ensure the analog input drive amplifier has sufficient slew rate to settle within the 11 ns acquisition window at full speed. A 50 ohm source-terminated differential layout is recommended for applications above 30 MHz analog input to preserve the ENOB. Use the internal reference for best noise performance; an external reference can be driven but is rarely required.

MAX1026BCEE+T - 10-Bit 300ksps ADC w/FIFO, QSOP-16 | Maxim
The Analog Devices (formerly Maxim Integrated) MAX1026BCEE+T is a 10-bit, 300 ksamples-per-second successive-approximation analog-to-digital converter (SAR ADC) with integrated FIFO, internal temperature sensor, and internal voltage reference, housed in a 16-pin QSOP package. It accepts 4 or 8 single-ended analog inputs on a serial SPI/QSPI/MICROWIRE-compatible interface, and operates from a single +5V analog supply with a separate digital supply. An ADC (analog-to-digital converter) is a semiconductor device that converts real-world analog signals into discrete digital codes for processing by microcontrollers, DSPs, or FPGAs. Within the broader taxonomy, the MAX1026 belongs to successive-approximation ADCs (SAR ADCs) — a sub-family of data converters that prioritize low latency, deterministic conversion, and high accuracy at sample rates up to ~1 Msps, sitting under the broader categories of data converter ICs -> signal chain ICs -> power-management-and-analog mixed-signal ICs. The MAX1026 targets embedded designers who need a multi-channel, mixed-signal front end without an external reference or analog temperature sensor, simplifying bill-of-materials and layout. Key features include true 10-bit resolution with no missing codes, a 300 ksps throughput, an internal 2.5V bandgap reference (with external override option), an internal die-temperature sensor readable through the same analog-input path, and a 2,304-sample FIFO that offloads the host controller. The 4-/8-input multiplexer lets the part scan multiple sensors or potentiometers, while the integrated temperature sensor simplifies system-level thermal management. The serial interface reduces pin count and board area versus parallel ADCs. The internal architecture is a classical charge-redistribution SAR core followed by a digital correction/AEC engine, an 8-input front-end multiplexer with track-and-hold, and an internal 2.5V reference with a buffered output. The host-side FIFO enables burst-mode acquisition and relaxed interrupt service routines, making the part well-suited for industrial control loops where timing budgets are tight. Compared with slower I2C ADCs, the SPI-compatible MAX1026 trades interface simplicity for substantially higher sample rates and deterministic timing. Typical applications include multi-channel data-acquisition front ends for industrial PLCs, programmable logic controllers and process-control boards, portable and bench-top test-and-measurement instruments, and embedded temperature-monitoring systems. The internal FIFO also fits battery-powered portable sensor-hub designs where the host controller sleeps between burst-readings. A key design consideration is proper grounding: the analog and digital grounds should be tied at a single star point near the AGND pin to avoid digital noise coupling into analog conversions. Adding a small RC network on REF (typically 0.1 µF + 10 µF) is recommended for high-frequency noise rejection. Designers should also size the FIFO watermark interrupt so the host CPU does not need to service the converter for every single sample.

The base MAX1030BCEG silicon supports 8/16 single-ended or 4/8 differential analog input channels, programmable scan mode, internal averaging, and a serial SPI/QSPI/MICROWIRE-compatible interface. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that quantizes a continuous-time, continuous-amplitude analog input into a discrete digital code. Successive-approximation register (SAR) ADCs like the MAX1030 use a binary-search algorithm with an internal DAC and comparator to resolve N bits in N clock cycles, achieving a strong trade-off between sample rate, accuracy, and low power consumption. Within the broader hierarchy, the MAX1030 is a precision SAR ADC, a sub-category of data-conversion ICs that sits under signal-chain and data-acquisition products. Key specifications include 10-bit resolution, 300 ksps maximum sampling rate, 8/16 single-ended or 4/8 differential input channels, an internal 4.096 V reference, an integrated on-chip FIFO that offloads host-processor overhead, an internal temperature sensor with ±2 °C accuracy (typical), and an operating supply range of +4.75 V to +5.25 V (analog) and +2.7 V to +5.25 V (digital). AutoShutdown reduces supply current between conversions to microampere levels, suiting battery-powered data-acquisition applications. The MAX1030BCEG+TG002 uses a switched-capacitor input architecture with a high-impedance analog input multiplexer. The internal FIFO can buffer multiple conversion results, and internal averaging supports oversampling to improve effective resolution. The 24-QSOP package is footprint-compatible with the MAX1026 (12-channel) and MAX1028 (8-channel) family members, allowing channel-count scaling without PCB rework. Typical applications include industrial process control, multichannel data-acquisition systems, patient monitoring and portable medical instruments, battery-powered sensor systems with temperature compensation, system supervisory monitoring (using the on-chip temp sensor), and front-end digitizing for instrumentation. The +5 V analog supply and 5 V digital I/O make it a natural fit for legacy 5 V microcontrollers and embedded DSP systems. When designing with the MAX1030BCEG+TG002, observe the analog/digital supply sequencing guidelines in the manufacturer datasheet. Place the 0.1 µF and 10 µF decoupling capacitors as close as possible to the AVDD/DVDD pins, and keep analog inputs away from digital switching traces to preserve the 10-bit linearity and SNR performance.

It provides 8- or 16-channel single-ended or differential inputs, configurable through software, and supports an SPI/QSPI/MICROWIRE-compatible serial interface. A successive-approximation register ADC is a type of data converter that resolves one bit per internal clock cycle using a binary-search algorithm against a precision reference; it sits in the broader taxonomy of ADCs alongside sigma-delta, pipelined, and flash converters. The SAR architecture excels at low-latency, mid-speed multi-channel applications because each conversion completes in a deterministic number of cycles rather than integrating over many samples. The MAX1030's BiCMOS process integrates the analog input mux, sample-and-hold, reference, and digital FIFO on a single die. Key features include an integrated temperature sensor with ±1°C accuracy, an internal 4.096 V reference (or external reference option), a 16-entry FIFO that offloads host-processor traffic, and software-configurable unipolar/bipolar ±12 mA analog inputs. The internal analog input multiplexer allows scanning across 8 or 16 channels, making the part suitable for sensor-array applications. A dedicated reference output pin can drive external circuitry. Typical applications include system monitoring in networking and server hardware, multi-sensor data acquisition for industrial control, portable medical instrumentation with on-board temperature compensation, and front-end digitization for process-control loops. The integrated FIFO and temperature sensor simplify firmware by reducing host polling overhead. When designing with the MAX1030BETI+, ensure that the analog supply (AVDD) is well decoupled with a 10 µF tantalum plus 0.1 µF ceramic combination, and place the bypass capacitor as close as possible to the AVDD pin. Route the REF pin trace away from switching nodes to avoid reference noise coupling, and respect the 4.096 V absolute maximum reference voltage when interfacing to external sensor bridges. This page synthesizes distributor pricing, drop-in Maxim alternatives, and practical design guidance not found in the bare datasheet, helping engineers shorten their BOM evaluation cycle.

According to the manufacturer datasheet, it delivers up to 115 ksps throughput, integrates an on-chip +4.096 V reference, and accepts an external reference between 3.800 V and 4.136 V. The MAX1033EUP+ ships in a 20-pin TSSOP package specified from -40°C to +85°C. A SAR ADC is a type of data converter that resolves each conversion in N clock cycles by switching a binary-weighted capacitor array against the input, then digitizes the residual with a comparator. SAR-ADC sit-to-ADC-data-converter-place in the broader hierarchy: ADC-to-data-converter-to-data-acquisition-IC-to-signal-chain-IC-to-integrated-circuit. SAR ADCs offer deterministic latency, no pipeline delay, and excellent DC accuracy, making them preferred over delta-sigma ADCs for multiplexed analog front ends where per-channel settling must be predictable. Key features include true bipolar ±12 V input range without external signal conditioning, software-configurable unipolar 0-12 V or ±12 V ranges, 4-channel single-ended or 8-channel pseudo-differential input mux, internal 4.096 V reference with external override, SPI/QSPI/MICROWIRE-compatible serial port, and low 2.5 mA operating supply current. The MAX1033EUP+ achieves >14-bit no-missing-codes and ±1 LSB INL and DNL, supporting industrial-grade measurement repeatability. The MAX1033EUP+ uses a charge-redistribution DAC core with input overvoltage protection up to ±16.5 V. Its track-and-hold amplifier accepts fast-slewing multiplexed signals, and an integrated input clamp limits fault current. The device supports either an internal or external reference and provides a serial interface compatible with SPI/QSPI/MICROWIRE for direct connection to microcontrollers, DSPs, and FPGAs. Typical applications include industrial process control, multi-channel data loggers, portable instrumentation, and battery-powered sensor readout. Its wide ±12 V input range eliminates external resistor dividers in 4-20 mA loop-powered transmitters and thermocouple front ends, simplifying BOM and PCB layout. When designing with the MAX1033EUP+, use a 0.1 µF ceramic bypass capacitor within 5 mm of the AVDD pin and a 10 µF bulk capacitor on DVDD to decouple filter ground bounce from the reference. Keep analog and digital grounds separated and joined at a single star point beneath the IC. Do not apply inputs before power-up; the input ESD clamp draws current if VDD = 0 V.

An ADC (analog-to-digital converter) is a data-conversion integrated circuit that samples continuous analog signals and outputs discrete digital codes, serving as the bridge between real-world analog transducers (sensors, transducers, instrumentation amplifiers) and a digital host (microcontroller, DSP, FPGA). Successive-approximation ADCs like the MAX1033EUP+T use an internal binary-search loop against a precision reference, balancing 14-bit resolution, 115 ksps throughput, and modest power consumption, fitting into the data converter > ADC > SAR-ADC > multirange-ADC product hierarchy. Key features include ±12 V (or 0 to +12 V) true bipolar/unipolar input range with internal ±3x reference gain scaling, an integrated +4.096 V on-chip reference, software-configurable unipolar/bipolar inputs, 4 single-ended or 2 pseudo-differential channels, 115 ksps maximum sample rate, low +5 V single-supply operation, and a 3-wire SPI/MICROWIRE serial interface. The input architecture allows direct digitization of ±10 V industrial signals without external signal conditioning or resistor dividers. The MAX1033EUP+T uses a charge-redistribution SAR core combined with an input signal scaler that multiplies the differential input by 1, 2, or 3 to maximize dynamic range against the internal 4.096 V reference. The wide ±12 V input range is achieved without external attenuation resistors, reducing board area, BOM cost, and source-impedance-induced gain errors compared with conventional 0-5 V ADCs. Typical applications include industrial process control and data acquisition, PLC analog input modules, multichannel instrumentation, factory automation sensors, medical instrumentation, and any ±10 V signal-chain where 14-bit resolution and 115 ksps throughput are sufficient. When designing with this part, place 0.1 µF ceramic bypass capacitors close to the supply pins, route the analog and digital grounds as separate planes joined at a single point near the IC, and keep the input traces short to preserve CMRR. The internal 4.096 V reference may be overdriven with an external reference (3.800 V to 4.136 V) if higher absolute accuracy or ratiometric measurements are required.

MAX1036EKA+G002 - 8-Bit I2C ADC, 4-Ch, SOT-23-8 | Maxim
The Maxim MAX1036EKA+G002 is a 2.7 V to 5.5 V, low-power, 4-/12-channel, 2-wire serial 8-bit analog-to-digital converter (ADC) with an internal 4.096 V reference and 188 ksps conversion rate, housed in an 8-pin SOT-23 package. The +G002 variant is a special-order code extension; the base MAX1036 die is the same as the standard MAX1036EKA+ part. An ADC (Analog-to-Digital Converter) is a data-acquisition integrated circuit that samples continuous analog voltage signals and converts them into discrete digital codes for processing by microcontrollers, DSPs, or FPGAs. Successive-approximation-register (SAR) ADCs like the MAX1036 family use an internal capacitive DAC and comparator to perform one-bit-per-clock conversions, offering deterministic latency, low power, and excellent DC accuracy for multi-channel sensor monitoring and instrumentation. Key features of the MAX1036EKA+G002 include four single-ended or two differential analog input channels (selectable), an internal track/hold (T/H), a 4.096 V internal reference (also configurable for external reference), a 400 kHz Fast-Mode and 1.7 MHz High-Speed-Mode I2C-compatible serial interface, and an operating supply range of 2.7 V to 5.5 V. The internal reference and 4-channel MUX allow direct connection to sensors without external scaling. The MAX1036 uses a low-charge-injection input T/H that supports input bandwidths well beyond the Nyquist limit for accurate sampling of fast signals. With 188 ksps throughput and 8-bit resolution, the device offers low latency for loop control and panel-meter designs. The I2C/SMBus-compatible 2-wire serial bus reduces microcontroller I/O pin count and supports multi-device addressing. Typical applications include portable instrumentation, battery monitoring, panel meters, isolated sensor data acquisition, and 4-20 mA loop-powered transmitters. The wide supply range and integrated MUX make it well-suited for handheld multi-channel measurement. When designing with this device, place a 0.1 uF bypass capacitor on the supply pin and use a low-impedance reference bypass capacitor. The I2C bus pull-ups must be sized correctly for the selected bus speed (400 kHz or 1.7 MHz). This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found on the standard distributor product pages, supporting component selection for new designs and BOM substitutions.
MAX1036EKA+G51 - 4/12-Ch 8-Bit I2C ADC, 5.5V | Maxim
The Maxim Integrated (Analog Devices) MAX1036EKA+G51 is a low-power, 4-/12-channel, 8-bit analog-to-digital converter (ADC) with an I2C-compatible 2-wire serial interface, offered in an 8-pin SOT23 package. According to the verified distributor listing, the part operates from a single 2.7V to 5.5V supply, integrates an internal track/hold, voltage reference, and clock, and supports 400 kHz Fast Mode and 1.7 MHz High-Speed Mode I2C operation. An 8-bit ADC (analog-to-digital converter) is a data-acquisition building block that quantizes an analog input voltage into 256 discrete digital codes, forming the lowest-resolution tier of the successive-approximation (SAR) ADC family. Within the broader signal-chain hierarchy - sensor -> signal conditioning -> ADC -> digital processing - 8-bit SAR ADCs are typically deployed where compact size, low power, and modest precision are required (e.g., system monitoring, threshold detection, simple instrumentation). The MAX1036/MAX1038 family specifically adds an internal 4.096V reference and 4 or 12 analog input channels, which positions the MAX1036EKA+G51 as a space-saving, low-pin-count alternative to discrete ADC + external reference solutions. Key features include a low supply current of approximately 350 uA at the maximum 225 ksps conversion rate, an internal 4.096V reference for the MAX1036 variant, software-configurable unipolar/bipolar input range, automatic channel scanning, and an I2C address that is hardware-selectable via an external resistor. The SOT23-8 package enables the part to fit next to sensors in tightly constrained PCB areas while still offering 12 single-ended or 6 differential input channels on the die (only AIN0-AIN3 are bonded out for the EKA/8-pin variant). The internal architecture uses a successive-approximation register (SAR) core, an integrated input track/hold, an on-chip 4.096V bandgap reference, and a state machine that supports both single-ended and differential conversions with software-selectable unipolar/bipolar input ranges. The +G51 suffix is a Maxim tape-and-reel packaging code, not an electrical variant, so the silicon matches the standard MAX1036EKA. Typical applications include portable/battery-powered sensor monitoring, system voltage and temperature supervision, panel-meter front-ends, and consumer-electronics housekeeping ADCs. The wide 2.7V-5.5V supply range allows the part to be powered directly from a single Li-ion cell, a 3.3V rail, or a 5V microcontroller supply without level shifters. When laying out a board, place the 0.1 uF supply bypass capacitor as close as possible to the VDD pin and keep analog input traces short and guarded to minimize digital coupling. The internal reference requires a minimum 0.1 uF external bypass capacitor on REF for low-noise operation.

The Maxim Integrated MAX1036EKA+TG002 is a low-power, 4-channel (single-ended) or 12-channel (single-ended) successive-approximation 8-bit analog-to-digital converter (ADC) housed in an 8-pin SOT-23-8 package. Operating from a single 2.7V to 5.5V supply, it delivers up to 94 ksps throughput, 1.5 mA supply current, and an internal 2.048V reference. The +TG002 suffix indicates a specific tape-and-reel packaging option supplied as bulk-packed units. An SAR (Successive Approximation Register) ADC is a class of data converter that uses a binary-search algorithm combined with an internal DAC to resolve analog inputs in N conversion cycles for N-bit precision. The MAX1036 family integrates a track-and-hold amplifier, internal voltage reference, internal oscillator, and an I2C-compatible 2-wire serial interface (400 kHz Fast Mode and 1.7 MHz High-Speed Mode) into a single die, allowing direct connection to a microcontroller or processor without external precision components. Key features include four analog inputs configurable as either 4 single-ended or 12 single-ended channels via software, an internal 2.048V reference (with the option to use an external reference up to AVDD), software-configurable unipolar/bipolar modes, low supply current, and an automatic power-down between conversions that drops consumption to microampere levels. The internal reference provides tight initial accuracy and low drift, simplifying BOM cost and PCB area. Architecture is a charge-redistribution SAR with switched-capacitor input, supporting 0 to VREF input range. The 2-wire interface is I2C-compatible with address selection, enabling up to four MAX1036 devices on the same bus. AutoShutdown reduces average supply current to 200 uA at low throughput. Typical applications include portable instrumentation, battery monitoring, system monitoring in servers and networking equipment, panel meters, and digital multimeters. The wide supply range (2.7V to 5.5V) and small SOT-23 footprint make it well-suited for space-constrained, low-power designs. A design consideration: the SOT-23-8 package has a thermal resistance around 170 C/W; ensure decoupling with 0.1 uF and 1 uF capacitors close to AVDD, and route analog/digital grounds in a star-ground pattern to minimize digital switching noise coupling into analog inputs.

MAX1037EKA+G05 - 8-Bit 4/12-Ch 2-Wire Serial ADC | Maxim
The Analog Devices (formerly Maxim Integrated) MAX1037EKA+G05 is a low-power, 8-bit, multi-channel analog-to-digital converter (ADC) in an 8-pin SOT-23 package. It operates from a single 2.7V to 5.5V supply, supports 4 analog inputs on the MAX1037 variant (the wider MAX1038/MAX1039 family offers up to 12 channels), and uses an I2C-compatible 2-wire serial interface that runs up to 400 kHz in Fast Mode. The +G05 suffix denotes a 5k-piece tape-and-reel packaging option; the bare MAX1037EKA+ ships in 2.5k reels. An 8-bit successive-approximation-register (SAR) ADC is a type of data converter that resolves an analog input to one of 256 discrete digital codes by stepping an internal DAC and comparing it against the sampled input each conversion cycle. SAR ADCs sit in the broader product hierarchy of analog-to-digital converters -> data converters -> data acquisition ICs -> signal chain semiconductors. They are favored over integrating or sigma-delta ADCs when low latency (one conversion per command, no digital filter settling) and simplicity matter more than absolute resolution. Key specifications of the MAX1037EKA+G05 include a maximum sampling rate of 188 ksps, a 350 uA supply current at maximum throughput, an internal 2.048V or 4.096V reference option (on pin-compatible MAX1036/MAX1038 family members), and an external reference mode. The device integrates an input track-and-hold, on-chip clock, and I2C address selection via the AD0 pin, eliminating the need for an external crystal or precision reference in most designs. The single-ended analog inputs accept 0V to VREF (or 0V to VDD when using the supply as reference) and present a high-impedance input typical of switched-capacitor SAR front-ends. Typical applications for the MAX1037EKA+G05 include battery-cell monitoring in portable instruments, thermistor or ratiometric sensor readout in HVAC controllers, push-button and rotary-encoder position sensing, and loop-powered 4-20 mA receiver cards. Its 350 uA active current and sub-microamp standby mode make it well suited to energy-harvesting and always-on IoT nodes that periodically wake to digitize sensor voltages. Designers should note that the MAX1037's 4 single-ended inputs (AIN0-AIN3) are sampled sequentially through the internal MUX; sampling rate must be derated when scanning multiple channels in continuous-conversion mode. The 8-pin SOT-23 requires careful analog-layout practice - keep the analog ground return directly under the IC and decouple VDD with a 1 uF X7R ceramic placed within 3 mm of the supply pin to suppress the digital switching transients that couple back into the SAR comparator.

The +TG05 suffix indicates a custom reel/programmable factory configuration, with the standard MAX1037EKA+ being the off-the-shelf variant of the same die. An analog-to-digital converter (ADC) is a data-acquisition building block that converts real-world analog signals into discrete digital codes for processing by microcontrollers, DSPs, or FPGAs. Successive-approximation-register (SAR) ADCs like the MAX1037EKA+TG05 sit in the broader hierarchy of mixed-signal data converters, alongside delta-sigma, pipeline, and flash architectures. SAR ADCs are favored where low latency, moderate resolution (8-16 bits), and deterministic latency are required - making the MAX1037EKA+TG05 a representative part of the 8-bit, low-power, I2C-interfaced SAR family. Key features of the MAX1037EKA+TG05 include 4 analog input channels (single-ended or pseudo-differential), 188 ksps maximum sampling rate, internal 4.096 V reference (MAX1036/MAX1038) or external reference option, 350 µA supply current at maximum throughput, and a 2-wire I2C-compatible serial interface supporting both 400 kHz Fast Mode and 1.7 MHz High-Speed Mode. The SOT-23-8 footprint occupies less than 9 mm² of board area, ideal for portable and space-constrained designs. Architecturally, the MAX1037EKA+TG05 uses a charge-redistribution SAR core, an input multiplexer, an internal reference buffer, and an I2C/SMBus-compatible slave interface. The 1:1 input MUX:S/H:ADC ratio, single ADC, and selectable reference type (internal or external) allow designers to trade noise performance against input range flexibility on a per-channel basis. Typical applications include portable instrumentation, battery-powered sensor monitoring, consumer-electronics front ends, industrial process-control signal conditioning, and any system requiring 4-12 channels of moderate-resolution digitization behind a low-pin-count I2C bus. The wide 2.7-5.5 V supply range also covers 3.3 V and 5 V rails common in MCU-based designs. When designing with this ADC, place 0.1 µF decoupling capacitors as close as possible to the supply pin and follow Maxim's I2C bus-layout guidelines (4.7 kΩ pull-ups, ≤ 20 pF total bus capacitance in Fast Mode). For best noise performance, configure unused analog inputs as AIN_GND and avoid routing digital lines parallel to the analog inputs. The factory-custom +TG05 reel variant is best treated as a special-order item with non-cancellable/non-returnable terms.

According to the manufacturer datasheet, the part combines an 8-channel input MUX with a true SAR core, internal track/hold, internal clock, and 2.5V reference into a single mixed-signal IC optimized for data-acquisition front ends. A SAR ADC (Successive-Approximation Register Analog-to-Digital Converter) is a type of data converter that converts an analog input voltage into a digital code using a binary search algorithm against an internal precision reference. SAR ADCs occupy the middle tier of the ADC taxonomy - faster than integrating ADCs (such as dual-slope), more accurate and lower-noise than flash ADCs at moderate resolution, and well suited to multiplexed multi-channel systems where one ADC serves several sensors. They sit within the broader data-converter family (SAR, sigma-delta, pipeline, dual-slope) used in data acquisition, instrumentation, and process control. Key features include 400 ksps throughput, 4/8 analog input channels selected via on-chip MUX, integrated +2.5V reference (stable over temperature), automatic power-down between conversions for reduced quiescent draw, 2 microsecond wake-up time, parallel byte-wide digital output, and single +5V analog supply operation. The internal reference eliminates an external reference component and minimizes PCB area. Channel flexibility (4 or 8 inputs software-configurable) supports applications requiring multiple sensor readings per scan. The MAX1060 uses an internal charge-redistribution DAC array and precision comparator to implement its SAR conversion. The architecture delivers no-pipeline-delay sampling and inherent single-shot accuracy, making the part suitable for multiplexed systems where channel-to-channel settling must be deterministic. Internal input track-and-hold supports signals up to the Nyquist limit of the 400 ksps sampling rate, and the integrated reference removes drift concerns in cost-sensitive designs. Typical applications include portable and battery-powered data loggers, industrial process-control front ends, multi-sensor instrumentation, patient-monitoring medical devices, and pen-digitizer/tablet digitizing systems. The wide channel count and integrated reference suit any multi-channel 5V analog signal chain. When designing with this device, ensure the analog input range stays within the recommended common-mode window of the +5V supply and that adequate decoupling (typically 0.1 uF plus 10 uF bulk) is placed close to AVDD and DVDD pins. The internal +2.5V reference requires no external bypass but the supply pins do. Power-down mode should be used aggressively between conversions in battery applications to maximize runtime.

It operates from a single +5V analog supply, draws approximately 1.9 mA in normal operating mode, and includes a hardware power-down mode that reduces supply current to under 10 uA for battery-powered applications. A successive-approximation register (SAR) ADC is a type of data converter that converts an analog input signal into a digital code by iteratively approximating the input voltage against an internal digital-to-analog converter (DAC). SAR ADCs are favored in industrial and instrumentation designs because they offer deterministic latency, no pipeline delay, and excellent DC accuracy at sample rates up to several Msps. The MAX1060 belongs to the SAR ADC -> ADC -> data converter -> mixed-signal IC hierarchy, and within Maxim's portfolio it shares a common architecture with the MAX1062/MAX1063 family. Key features include a true-differential analog input track-and-hold amplifier with 4 MHz full-power bandwidth, an internal +2.5V reference with 50 ppm/°C typical drift, software-configurable unipolar (0 to VREF) or bipolar (±VREF/2) input ranges, and a single +5V analog supply requirement. The integrated reference eliminates the need for an external precision reference, which reduces BOM cost and board area in multi-channel data-acquisition systems. The MAX1060 is typically used in industrial process control, portable instrumentation, and data-logging designs that need simultaneous-sampling-free multichannel conversion with deterministic throughput. Its 400 ksps throughput and 8 single-ended input channels make it suitable for digitizing sensor arrays, multiplexer-front-ended measurement systems, and embedded control loops. When designing with this part, place the supply bypass capacitors as close as possible to the AVDD and DVDD pins and avoid routing digital signals across the analog input traces. The internal reference output (REF) requires a 4.7 uF bypass capacitor for specified noise performance; using a smaller value will degrade SNR. Do not operate below 4.75V without consulting the manufacturer's datasheet because the internal reference regulation may be compromised.

The wide 4 MHz full-power bandwidth and 10 kHz full-linear bandwidth make the part suitable for both DC and dynamic measurement tasks. Power-down modes reduce current to 2 µA between conversions for battery-friendly operation. The MAX1067BCEE uses a charge-redistribution DAC with a precision bandgap reference. The internal reference buffer drives the SAR comparator reference node, minimizing external component count. The 4-wire serial interface with active-low CS, SCLK, and DOUT supports daisy-chaining and is directly compatible with common DSP/MCU SPI peripherals. The scan mode automatically sequences conversions across the enabled channels, offloading CPU burden. Typical applications include portable data logging, process control and instrumentation, medical instrumentation, battery-powered monitoring, factory-automation sensor interfaces, and multichannel 4-20 mA loop digitizers. The 4-channel single-ended mux makes it a fit for quad-zone temperature or pressure monitoring where each sensor needs independent conversion and a shared reference. When designing with the MAX1067BCEE, allocate a quiet analog ground plane and decouple AVDD/DVDD with 1 µF and 0.1 µF ceramics as close to the pins as possible. Drive unused analog inputs to AVDD/2 to prevent ESD damage and to avoid the extra supply current caused by floating input protection diodes.

The device operates from a 4.75 V to 5.25 V analog supply, with a separate digital supply range of 2.7 V to 5.25 V for flexible logic-level interfacing. What is a SAR ADC? A successive-approximation register analog-to-digital converter is a type of data converter that uses a binary-search algorithm against an internal DAC to resolve an analog input to N bits in N clock cycles. SAR ADCs offer an attractive trade-off between sample rate (typically 1 ksps to 1 Msps), resolution (8 to 20 bits), power consumption, and latency, making them the workhorse of mid-speed precision measurement applications where single-shot or burst conversions are needed. They sit in the broader hierarchy: ADC -> data converter -> mixed-signal IC -> semiconductor. Key features of the MAX1069AEUD+ include automatic power-down between conversions (reducing supply current to microampere levels), an on-chip 4 MHz oscillator, software-configurable unipolar/bipolar input ranges, and an internal or external reference option. The 14-pin TSSOP footprint is pin-compatible with the higher-resolution 16-bit MAX1169 family, allowing easy migration when system SNR requirements grow. The MAX1069 architecture combines a capacitive-DAC SAR core with an input track-and-hold, a comparator, and a sequencer. The internal 4.096 V reference provides approximately 1 LSB = 250 uV at full-scale, while the wide digital supply range permits direct connection to 3 V or 5 V microcontrollers without level shifters. This combination is well suited to portable instrumentation, medical monitors, and solar-powered remote sensor nodes where both precision and low quiescent current are required. Typical applications include handheld portable instruments, medical instrumentation, battery-powered test equipment, solar-powered remote systems, received-signal-strength indicators (RSSI) for RF links, and system supervision in industrial control. Designers should note that decoupling the analog and digital supplies with separate 0.1 uF + 10 uF capacitors is essential, and the I2C address is set by hard-wiring ADD0-ADD3 to GND or VDD before power-up. This page synthesizes distributor stock, drop-in pin-compatible alternatives, and practical layout notes that are not present in the bare datasheet, giving engineers a single decision-ready reference for the MAX1069AEUD+.
MAX1069AEUD+T - 14-Bit 58.6ksps I2C SAR ADC | Analog Devices
The Analog Devices (formerly Maxim Integrated) MAX1069AEUD+T is a low-power, 14-bit, 58.6 ksps successive-approximation analog-to-digital converter (SAR ADC) in a 14-pin TSSOP package with automatic power-down, an on-chip 4 MHz clock, a +4.096 V internal reference, and an I2C-compatible 2-wire serial interface supporting both fast-mode (400 kHz) and high-speed-mode (1.7 MHz) operation. A SAR ADC is a successive-approximation-register analog-to-digital converter: a sample-and-hold captures the input, an internal DAC and comparator walk through each bit from MSB to LSB in one clock cycle per bit, and the digital result is latched out. SAR ADCs are valued for deterministic latency, low latency, no pipeline delay, and excellent DC accuracy. As a data converter, this device belongs to the broader hierarchy: ADC -> data converter -> signal chain IC -> mixed-signal semiconductor. Key features include 14-bit resolution, 58.6 ksps sampling rate, single +2.7 V to +5.25 V analog supply, a 4.096 V internal reference, four address-select pins (ADD0-ADD3) that allow up to 16 MAX1069 devices on the same I2C bus, automatic power-down between conversions to minimize current draw, and an I2C/SMBus-compatible 2-wire serial interface. The TSSOP-14 footprint is one of the most common small-outline surface-mount packages in the TSSOP family of thin-shrink small-outline packages. The architecture combines a capacitive-charge redistribution DAC with an on-chip clock and reference, eliminating most external components. Power-down currents drop to the sub-microamp region between conversions, making the part well suited to duty-cycled or battery-aware designs where the MCU wakes, takes a reading, and sleeps. Typical applications include handheld portable instrumentation, medical instruments, battery-powered test equipment, solar-powered remote systems, received-signal-strength indicators (RSSI), and system supervision. Designers usually select the MAX1069AEUD+T when they need a small, low-power, 14-bit accurate ADC with an easy I2C interface and multi-drop addressing on a tightly board-constrained PCB. When designing, observe the analog/digital supply decoupling guidance in the manufacturer datasheet, place the reference bypass capacitor close to REF, and keep the analog input traces short and guarded. Avoid driving the analog input beyond the supply rails to prevent ESD latch-up, and respect the maximum I2C clock rate of the chosen bus mode. This page combines distributor pricing, drop-in pin-compatible alternatives, and practical design notes curated from the manufacturer datasheet, going beyond what the datasheet alone provides.
