MAX1070CTC+ - 1.5Msps 10-Bit Differential ADC | Analog Devices
The Analog Devices MAX1070CTC+ is a 1.5Msps, single-supply, low-power, true-differential, 10-bit analog-to-digital converter (ADC) with serial output, housed in a 12-pin TQFN package. It operates from a single +5V analog supply and a separate +2.7V to +5.25V digital supply, making it suitable for mixed-signal boards where the digital logic runs from a lower rail than the analog front end. A Successive Approximation Register (SAR) ADC is a converter architecture that resolves each digital code one bit at a time using an internal precision DAC and a comparator, trading raw speed for very low power dissipation and inherent latency determinism. Within the broader product hierarchy, SAR ADCs sit under the ADC IC family, which itself is a sub-category of data converters and ultimately of mixed-signal / power-management semiconductor ICs. The MAX1070's 1.5Msps throughput, true-differential analog inputs and SPI/QSPI/MICROWIRE-compatible serial interface place it firmly in the mid-speed, low-power tier of this hierarchy, between precision 16-/18-bit converters and kilosample-per-second delta-sigma converters. Key features include true-differential analog inputs for better common-mode noise rejection, a high-impedance analog input stage with ±VREF input range, internal +2.5V reference, an external reference option, and a power-down mode that drops supply current to a few microamps between conversions. The serial interface eliminates parallel digital bus noise on the PCB and allows the device to be used with virtually any microcontroller or FPGA. Built-in track-and-hold and a wide ±0.5 LBN INL/DNL specification deliver predictable linearity for closed-loop control loops. Typical applications include motor-control current/voltage sensing, industrial process-control analog front ends, portable instrumentation with battery-saving power-down sequencing, and optical/sensor signal conditioning. The MAX1070's low quiescent current and small TQFN footprint suit it particularly to space-constrained or thermally sensitive embedded designs. Designers should observe the analog and digital ground separation recommended in the manufacturer datasheet and place the decoupling capacitor as close as possible to the supply pins.

The Analog Devices (formerly Maxim Integrated) MAX1070CTC+T is a 1.5Msps, single-supply, low-power, true-differential, 10-bit successive-approximation analog-to-digital converter (ADC) housed in a 12-pin WQFN (HVQCCN) package. It operates from a single 2.7V to 3.6V analog supply and supports true-differential analog inputs, with throughput up to 1.5 million samples per second over an SPI-/QSPI-/MICROWIRE-compatible serial interface. The integrated 2.5V on-chip reference and low 3.2mA (typ) operating current make it attractive for power-constrained data-acquisition designs. What is a SAR ADC? A successive-approximation-register analog-to-digital converter is a sampled-data ADC class that uses a binary-search algorithm against an internal DAC to resolve each conversion in N clock cycles (N = resolution in bits). SAR ADCs sit in the broader hierarchy ADC -> data converter -> mixed-signal IC -> semiconductor, and are favored over delta-sigma and pipeline ADCs for multiplexed-channel, low-latency, medium-resolution (8-16 bit) applications because they require no digital filtering and offer deterministic latency. Key differentiating features of the MAX1070CTC+T include the true-differential input architecture (rejecting common-mode noise in industrial environments), an integrated 2.5V internal reference (eliminating an external reference IC and saving board area), a hardware/software shutdown pin that reduces supply current to ~1µA between bursts, and a 10MHz SPI-compatible serial interface that minimizes pin count and simplifies optocoupling to isolated controllers. The 12-pin WQFN (HVQCCN, 4x4 mm) footprint is thermally efficient and suitable for hand-solderable QFN replacement in low-volume designs. The T suffix denotes tape-and-reel packaging for high-volume SMT assembly. Typical applications include industrial process-control loops (4-20mA sensor digitization), portable instrumentation and battery-powered data loggers, multichannel data-acquisition (DAQ) systems, optical-module monitoring, and ultrasound or vibration front-ends where the differential input improves rejection of ground-bounce and motor noise. When designing with this part, place 0.1µF bypass capacitors as close as possible to AVDD and DVDD, and add a 10µF bulk tantalum on AVDD. The internal reference noise is typically 2.4mV p-p; for systems requiring lower noise, override REF with an external 2.5V reference such as the MAX6143. The shutdown pin (SHDN) can be driven from a logic output or tied high for always-on operation.

According to the manufacturer datasheet, the MAX1070 and MAX1071 are pin-compatible family members that differ primarily in resolution (MAX1070 is 12-bit, MAX1071 is 10-bit), giving designers a migration path between precision levels without PCB rework. A successive-approximation ADC is a type of data converter that converts an analog input voltage into a digital code through a binary-search algorithm using an internal DAC and comparator. SAR ADCs sit in the hierarchy: ADC -> data converter -> data acquisition IC -> signal chain IC -> semiconductor. They are favored for applications requiring high accuracy, low latency, and deterministic sampling, which sets them apart from delta-sigma ADCs (higher resolution, slower) and pipeline ADCs (very fast, higher latency). The MAX1071 belongs to the SAR family. Key features include true-differential analog inputs for superior common-mode noise rejection, an internal 2.5V reference (with the option to drive an external reference), an SPITM/QSPI/MICROWIRE-compatible serial interface, and a hardware- or software-controlled shutdown mode that drops supply current to the microampere range between conversions. The 12-pin TQFN package offers a compact 4x4 mm footprint with an exposed pad for low thermal resistance and improved electrical grounding. The +T suffix indicates tape-and-reel packaging for high-volume assembly. From an architecture standpoint, the MAX1071 uses a capacitive-charge-distribution DAC combined with a high-bandwidth comparator and a precision 2.5V bandgap reference. The true-differential input structure allows direct measurement of bridge sensors, thermocouples, and other small differential signals without external instrumentation amplifiers, which simplifies the analog front-end and reduces total BOM cost. Typical applications include industrial process control, data acquisition systems, portable instrumentation, battery-powered sensor monitoring, optical module monitoring, and motor control feedback loops. The differential input architecture also makes it well-suited to medical instrumentation front-ends and sonar/radar intermediate-frequency sampling where ground noise is a concern. A key design consideration is input common-mode voltage and source impedance: the input sampling capacitors require adequate settling time, so place a low-impedance buffer or anti-alias RC network immediately ahead of AIN+ and AIN-. For best linearity, drive REF+ directly from a low-noise reference source and decouple REF- to analog ground with a 0.1uF ceramic capacitor placed within a few millimeters of the pin.

An SAR ADC is a successive-approximation register analog-to-digital converter - a category of data converter that uses a binary-search algorithm and an internal DAC to digitize an analog input one bit at a time per clock cycle. SAR ADCs occupy a middle position in the data-converter hierarchy between flash ADCs (fastest, lowest resolution) and sigma-delta ADCs (highest resolution, slowest). They deliver an excellent trade-off between speed, resolution, and power, which is why they dominate multi-channel, low-power embedded acquisition tasks. Key features include software-configurable analog inputs (unipolar/bipolar, single-ended/differential), four software-selectable power modes (normal, REDP, FASTPD, FULLPD), a hardware active-low SHDN pin, and automatic shutdown at the end of conversion to minimize battery drain.

The device combines a high-bandwidth track/hold (T/H) front-end that supports signals well beyond the Nyquist limit of its 400 ksps maximum sampling rate, ensuring accurate acquisition of fast transients. Its serial interface is SPI/QSPI/MICROWIRE-compatible, allowing direct connection to most microcontrollers and DSPs without glue logic. Typical applications include portable data acquisition, battery-powered instrumentation, multichannel sensor monitoring, process control, patient monitoring, and pen digitizers. The 8-channel input mux makes it well-suited for systems that must digitize multiple analog sources with one ADC. When designing with this part, place a 0.1uF bypass cap within 5 mm of VDD/REF pins and route analog and digital grounds separately back to a star ground to preserve the 10-bit linearity. AutoShutdown between conversions drops supply current to sub-microamp levels, so firmware should explicitly wake the part before each conversion burst.

Key features include a single-supply +2.7V to +3.6V analog supply (with a separate 3.3V-or-5V-tolerant digital interface on the MAX1083 variant), a hardware-configurable 2-channel or 4-channel analog input multiplexer (mux), an internal 2.5V reference, and a SPI/QSPI/MICROWIRE-compatible 4-wire serial interface that allows direct connection to most microcontrollers and DSPs without glue logic. The architecture pairs an input track/hold with the SAR core and an on-chip reference, eliminating the need for an external reference in many applications and reducing total BOM count. The wide input common-mode range and low analog-input leakage extend the device's usefulness in industrial sensor-interface designs. Typical applications include portable data logging, patient-monitoring and portable medical instruments, process-control analog I/O modules, and battery-powered instrumentation. The combination of low power consumption, small TSSOP-16 footprint, and 4-channel input mux makes it particularly well-suited to multi-sensor handheld designs where board space and battery life are at a premium. When designing with the MAX1082ACUE+T, ensure that decoupling capacitors are placed as close as possible to AVDD/DVDD, and that the analog and digital ground planes are joined at a single star point under the exposed thermal pad to minimize noise coupling into the SAR comparator.

MAX1082AEUE+TW - 10-Bit 400ksps 4-Ch SAR ADC | Maxim Integrated
The Maxim Integrated MAX1082AEUE+TW is a 10-bit, 400ksps, single-supply, 4-channel serial analog-to-digital converter (ADC) with internal reference, housed in a 16-pin TSSOP package. The device accepts analog inputs from 0 to +5V on a single +5V supply and supports an external reference option. The +TW suffix denotes tape-and-reel packaging for high-volume assembly. An SAR (Successive Approximation Register) ADC is a type of data converter that performs a binary search through the input voltage using an internal DAC and comparator, delivering a fixed conversion time independent of input magnitude. SAR ADCs occupy a middle ground between slow but precise delta-sigma ADCs and fast flash ADCs, making them the workhorse choice for industrial control, instrumentation, and multi-channel data-acquisition front-ends where deterministic latency and 8-12 bit resolution are required. Key specifications of the MAX1082AEUE+TW include 400ksps sampling rate (300ksps variant MAX1083 also shares the family), 10-bit resolution with ±1 LSB linearity, four single-ended analog input channels multiplexed through an on-chip T/H (track-and-hold), an internal 4.096V reference, and an SPI/QSPI/MICROWIRE-compatible serial interface. The device operates from a single +5V analog supply and a separate +5V or +3V digital supply, drawing only 2.5 mA operating current. The MAX1082AEUE+TW architecture combines an input MUX with a wide-bandwidth T/H front-end to settle 10-bit conversions in under 2.5 us, then shifts the result out through a 4-wire serial port. Internal software-configurable power-down reduces supply current to under 10 µA between conversions, enabling battery-friendly periodic-sampling designs. Typical applications include industrial process control loops, weigh-scale and load-cell signal chains, portable battery instrumentation, multi-zone temperature monitoring, and 4-20 mA loop digitization. The internal 4.096V reference conveniently scales a 0-4V sensor output directly to full-scale 10-bit codes. When designing with this ADC, place 0.1 uF and 10 uF decoupling capacitors as close as possible to the AVDD and DVDD pins and route the analog ground (REF_) and digital ground (DGND) as separate traces meeting only at the device GND pin. For highest DC accuracy, enable the internal reference and avoid injecting digital switching currents into the reference node.
MAX1082AEUE+W - 10-Bit, 4-Ch, 300ksps SAR ADC | Maxim Integrated
The Maxim Integrated MAX1082AEUE+W is a 10-bit resolution, 4-channel successive-approximation analog-to-digital converter (SAR ADC) capable of 300 ksps throughput in a 16-pin TSSOP package. The MAX1082 variant pairs the internal 2.5V reference with 300 ksps sampling; the closely related MAX1083 in the same family offers 400 ksps throughput for higher-speed designs. Both devices combine a 4-channel analog-input multiplexer, a high-bandwidth track/hold amplifier, and a serial (SPI/QSPI/MICROWIRE-compatible) interface on a single +2.7V to +3.6V supply. Background: An ADC (analog-to-digital converter) is a data-converter IC that translates real-world analog signals into digital codes for downstream processing by a microcontroller, DSP, or FPGA. Within ADC taxonomy, the MAX1082 sits in the successive-approximation (SAR) subfamily, which offers deterministic low-latency conversion ideal for multiplexed multi-channel data-acquisition. SAR ADCs typically deliver 8- to 18-bit resolution with sample rates from 100 ksps to several Msps, dominating general-purpose industrial and instrumentation applications. Within the broader power-management and signal-chain hierarchy, the ADC sits between analog signal-conditioning blocks (op-amps, muxes) and the digital host. Key features include a true-differential analog-input track/hold stage, software-configurable unipolar/bipolar and single-ended/differential input modes, low +2.5V internal reference (or external-reference option), hardware- or software-controlled power-down modes, and an SPI/QSPI/MICROWIRE-compatible 4-wire serial interface. The MAX1082AEUE+W operates from a single +2.7V to +3.6V supply and typically draws only 2.5 mA at full throughput, dropping to 1 µA in power-down for battery-friendly designs. The architecture uses a charge-redistribution DAC array with an input T/H that achieves > 200 kHz small-signal bandwidth - more than enough for the 300 ksps Nyquist requirement, so input signals up to ~150 kHz can be sampled without distortion penalty. The internal 2.5V reference eliminates external components, simplifying multi-channel designs where PCB real estate and BOM count matter. Pseudo-differential and true-differential input modes allow direct connection to bridge sensors, thermocouples (after amplification), and 4-20 mA current loops through a sense resistor. Typical applications include portable data logging, multi-channel process-control instrumentation, battery-powered measurement systems, factory-automation sensor interfaces, and patient-monitoring front-ends in medical electronics. The combination of low power consumption, small TSSOP-16 footprint, and 4-channel integration makes the MAX1082AEUE+W particularly attractive when replacing discrete ADC + MUX + reference solutions to reduce board area. Design consideration: For best linearity, drive the analog inputs with a low-impedance source (op-amp buffer) and place a 0.1 µF ceramic bypass capacitor within 5 mm of the AVDD pin. Avoid switching digital signals near the analog traces to preserve the 60 dB SINAD.

MAX1084BCSA - 400ksps Serial 10-Bit ADC | Maxim Integrated
The Analog Devices (formerly Maxim Integrated) MAX1084BCSA is a 400ksps/300ksps, single-supply, low-power, serial 10-bit analog-to-digital converter (ADC) with an internal reference, housed in an 8-pin SOIC (CSA) package. It combines a wide-bandwidth track-and-hold, a high-speed serial interface, and an internal 2.5V reference, delivering 10-bit resolution at up to 400ksps (MAX1084) or 300ksps (MAX1085) while operating from a single 4.5V to 5.5V analog supply. According to the Maxim datasheet, the device integrates a successive-approximation register (SAR) ADC core optimized for low power dissipation. An analog-to-digital converter (ADC) is a data-acquisition component that converts a continuous analog input voltage into a discrete digital code. SAR (Successive Approximation Register) ADCs use a binary-search algorithm against an internal DAC to resolve each conversion in N clock cycles, where N is the bit resolution (10 cycles for a 10-bit ADC). They sit within the data-converter hierarchy: ADC -> data converter -> data acquisition IC -> signal chain -> mixed-signal SoC. Compared with delta-sigma ADCs, SAR converters offer higher sample rates and lower latency, making them ideal for multiplexed multi-channel systems. Key features include 4.5V to 5.5V single-supply operation, an internal 2.5V reference (MAX1084A/MAX1085A) or external reference option, a high-speed SPI/QSPI/MICROWIRE-compatible serial interface, and low power consumption (typical 1.9mA at 400ksps, dropping to under 10µA in shutdown). The serial-interface daisy-chain capability allows multiple ADCs to share one processor port, reducing board area in multi-channel designs. The MAX1084BCSA uses a capacitive-charge redistribution SAR architecture with an input track-and-hold capable of handling full-scale inputs up to VREF. Its serial interface outputs MSB-first data with an external SCLK, simplifying connection to microcontrollers and DSPs. The 'BC' speed-grade suffix denotes the 400ksps MAX1084 variant (the 300ksps MAX1085 uses 'AC'). Typical applications include remote-sensor signal acquisition, portable data loggers, battery-powered instrumentation, multi-channel multiplexed data-acquisition systems, and pen-digitizer or touch-screen interfaces. Designers favor this part when serial output, small footprint (SO-8), and low quiescent current matter most. A practical design consideration: because the part is specified for 4.5V-5.5V analog supply, it is not directly 3.3V-rail compatible without a level shifter or local LDO. Decouple AVDD with a 10µF tantalum in parallel with a 0.1µF ceramic placed within 5mm of the supply pin.

The Maxim Integrated MAX1084BCSA+T is a 10-bit, 400ksps (kilosamples per second) single-supply, low-power, successive-approximation analog-to-digital converter (ADC) with an internal reference, offered in an 8-pin SO (SOIC) package with tape-and-reel packaging (the “+T” suffix). An ADC (analog-to-digital converter) is a data-conversion integrated circuit that samples continuous analog voltages and outputs discrete binary codes suitable for microcontrollers, DSPs, or FPGAs. Within the converter family hierarchy, the MAX1084 belongs to the successive-approximation register (SAR) ADC category, which sits under precision ADCs, which in turn sit under data converters and signal-chain ICs. SAR ADCs are valued for deterministic latency, low power, and high accuracy at moderate sample rates, making them the workhorse choice for multiplexed sensor reading and industrial control. Key electrical specifications include a 10-bit resolution, a 400 ksps maximum sample rate (when using an external clock), a single +5V analog supply, low power consumption suitable for battery-powered designs, an internal reference (eliminating an external reference IC), an SPI/QSPI/MICROWIRE-compatible serial interface, and an integrated high-bandwidth track/hold. According to the Maxim datasheet family (MAX1084/MAX1085), these converters combine ease of use with small footprint for space-constrained boards. Typical applications where the MAX1084BCSA+T fits well include remote-sensor and data-acquisition systems, portable and battery-powered instruments, process control loops, multiplexed analog input modules, and instrumentation where low quiescent current and small 8-pin SO packaging are required. The internal reference simplifies BOM (bill of materials) and PCB area, while the SPI-compatible serial interface minimizes microcontroller pin count. When designing with this ADC, ensure that the analog input does not violate the absolute input range relative to the analog supply rail, and place the recommended 0.1µF supply bypass capacitor directly at the AVDD pin. The serial interface allows direct connection to microcontrollers without external glue logic. This page synthesizes distributor pricing, parametric alternatives, and practical design notes not found on a single manufacturer datasheet page — a consolidated reference for engineers evaluating the MAX1084BCSA+T for new designs or as a drop-in replacement for MAX1242/MAX1243-series devices, which the datasheet notes are pin-compatible predecessors with lower sample rates.
MAX1084BESA - 10-Bit 400ksps SAR ADC | Maxim Integrated
The Maxim Integrated MAX1084BESA is a 10-bit successive-approximation analog-to-digital converter (SAR ADC) that samples at up to 400 ksps in an 8-pin SOIC surface-mount package. The part combines a high-bandwidth track-and-hold, a serial interface, an internal +2.5V reference, and low power consumption in a single-supply 5V design. A SAR ADC is a type of analog-to-digital converter that uses a binary search algorithm against an internal DAC to digitize an analog input one bit at a time per clock cycle. The architecture is favored for medium-resolution, medium-speed precision applications because it delivers deterministic latency and excellent DC accuracy without the complexity of pipeline or delta-sigma stages. SAR converters sit within the broader data-converter hierarchy above flash and integrating ADCs but below most delta-sigma and pipelined architectures in conversion speed. Key features of the MAX1084BESA include 400 ksps sampling rate, an internal +2.5V reference (eliminating an external reference component), single 5V analog supply operation, an SPI-/QSPI-/MICROWIRE-compatible serial interface, and a hardware shutdown pin for power saving. Low power consumption and an 8-pin small-outline package make the device well-suited to space- and energy-constrained designs. The MAX1084BESA is pin-compatible and a higher-speed functional upgrade to the legacy MAX1242/MAX1243 family, allowing designers to migrate existing boards to faster sampling with no PCB rework. Compared with the slower MAX1085 (300 ksps), it doubles throughput for the same package and pinout, simplifying BOM consolidation across speed variants. Typical applications include remote-sensor signal acquisition, industrial process control, portable instrumentation, weigh scales, and patient-monitoring front ends. The internal reference and small SO footprint reduce external parts count for handheld and battery-powered systems. When designing in this part, place the 0.1 µF bypass capacitor as close to the supply pin as the layout allows and keep analog/digital grounds joined at a single star point. Use the SHDN pin in battery-powered designs to idle the converter between conversions and minimize quiescent draw. The serial interface allows galvanic isolation through low-cost digital isolators where patient-safety or industrial isolation is required.
MAX1085ACSA+ - 10-Bit 300ksps Serial ADC | Maxim Integrated
The Maxim Integrated (Analog Devices) MAX1085ACSA+ is a 10-bit, 300 ksps, single-supply, low-power, serial-interface successive-approximation analog-to-digital converter (ADC) housed in an 8-pin SOIC (NSOIC/SOP) package. It combines a high-bandwidth track/hold, a serial SPI/QSPI/MICROWIRE-compatible interface, an internal +2.5V reference, and a low-power architecture, drawing only 2.5 mA typical supply current at 300 ksps while automatically powering down to under 1 µA between conversions. An SAR ADC is a successive-approximation register analog-to-digital converter — a type of data converter that uses a binary-search algorithm against a precision DAC to digitize an analog input one bit per clock cycle. SAR ADCs sit in the broader hierarchy of: ADC -> data converter -> mixed-signal IC -> semiconductor. Compared with delta-sigma ADCs, SAR parts offer deterministic latency and single-shot conversions, making them preferred for multiplexed data-acquisition front-ends and control loops. Compared with flash ADCs of the same bit count, SAR parts consume far less power and silicon area. Key features include 300 ksps maximum sampling rate (the 5 MHz clocked MAX1084 variant shares the same datasheet and pin-out at 400 ksps), 10-bit resolution, single-ended analog input, internal 2.5V reference (±1.5% initial accuracy), SPI/QSPI/MICROWIRE-compatible serial interface, 2.5 mA supply current at full speed, and automatic power-down between conversions. The 8-pin SOIC package provides a small footprint suitable for space-constrained industrial and instrumentation designs. The MAX1085 uses a charge-redistribution DAC array with an inherent sample-and-hold front-end, allowing the analog input to settle during acquisition without an external buffer. The internal reference eliminates the need for an external reference IC, reducing BOM cost and PCB area, while still offering ±1.5% initial accuracy suitable for general-purpose 10-bit measurement. Typical applications include portable data logging, pen-digitizer digitizing tablets, portable battery-powered instruments, isolated industrial 4-20 mA sensor digitizers, and general-purpose single-channel data acquisition. The MAX1085A grade offers specified AC electrical characteristics, while the MAX1085B grade offers slightly tighter linearity; the suffix "C" denotes the commercial 0 °C to +70 °C temperature range and "SA" denotes the 8-pin SOIC package. When designing with the MAX1085ACSA+, place a 0.1 µF bypass capacitor within 5 mm of the AVDD pin and keep the analog input traces short and guarded. The serial interface uses SCLK, DIN, DOUT, and active-low CS — tie DIN high when reading conversions only, or hardwire it for hardware-mode operation.
MAX1085ACSA+T - 400ksps 10-Bit Serial ADC | Maxim Integrated
The Maxim Integrated MAX1085ACSA+T is a 10-bit, 400ksps (max), single-supply, low-power, successive-approximation analog-to-digital converter (SAR ADC) with an internal +2.5V reference and serial (SPI/QSPI/MICROWIRE-compatible) interface, packaged in an 8-pin SOIC. It accepts a single analog input channel and combines a high-bandwidth track/hold, an internal reference, and low-power operation in a compact 8-pin SO footprint, targeting portable and remote-sensor data-acquisition applications. A SAR ADC is a type of analog-to-digital converter that uses a successive-approximation register to perform a binary search across an internal resistive ladder (or charge-redistribution capacitor array), producing one bit per clock cycle. SAR ADCs are valued for their deterministic latency (one conversion = N clock cycles), excellent DC linearity, intrinsic anti-alias filtering (no SHA in the feedback path of a sigma-delta), and low power consumption compared to flash or pipelined architectures. The MAX1085ACSA+T sits in the data-acquisition IC -> ADC -> SAR ADC -> 10-bit single-channel ADC -> precision signal-chain IC taxonomy, often used as a successor to legacy 12-bit pin-compatible parts like the MAX1242/MAX1243 when higher throughput is needed. Key features include a maximum sampling rate of 400ksps (MAX1085) versus 300ksps (MAX1084), an internal +2.5V reference (eliminating external reference components and saving PCB area), a single +2.7V to +5.5V analog supply, a low-power shutdown mode that drops supply current to under 1µA between conversions, an SPI/QSPI/MICROWIRE-compatible serial interface, and an 8-pin SOIC package rated for the 0°C to +70°C commercial temperature range (the +T suffix denotes tape-and-reel packaging). The MAX1085 uses a charge-redistribution SAR architecture with an integrated input track/hold, providing 10-bit no-missing-code performance, low integral nonlinearity (INL), and low differential nonlinearity (DNL). The internal reference is factory-trimmed, eliminating external reference noise and drift. The serial interface shifts out conversion results MSB-first, simplifying connection to microcontrollers, DSPs, and FPGA signal-chain front ends. Typical applications include portable data loggers, remote sensor digitizers (strain gauges, thermocouples with amplification), handheld instrumentation, pen-tablet digitizers, and battery-powered medical or industrial monitoring nodes. The low shutdown current makes it well suited to duty-cycled sampling on battery rails. When designing with this device, observe the analog input range relative to VDD (the input cannot exceed VDD + 0.3V), place a 0.1µF bypass capacitor close to VDD, and follow the serial-interface timing diagram exactly. The MAX1085ACSA+T is a drop-in functional equivalent of the MAX1085BCSA+T (the B-grade offers tighter linearity specifications but shares the same 8-pin SO footprint) and the MAX1084ACSA+T (lower 300ksps throughput, same footprint).

The Maxim Integrated MAX108CHC-B50105 is a PECL-compatible 8-bit ultra-high-speed analog-to-digital converter (ADC) that samples at 1.5 Gsps with an analog input bandwidth of 2.2 GHz. Housed in a 192-ball LBGA (chip-scale BGA) package, it integrates a high-performance track-and-hold (T/H) amplifier and a flash quantizer on a single monolithic die fabricated on Maxim's proprietary advanced GST-2 bipolar process. An 8-bit ADC (analog-to-digital converter) is a data-conversion integrated circuit that translates a continuous-time analog signal into an 8-bit digital code at a specified sample rate. High-speed 8-bit ADCs sit in the broader data-converter hierarchy (ADC > data converter > mixed-signal IC > semiconductor) and are typically used to digitize fast transient or RF signals where GHz-class analog bandwidth and multi-hundred-MHz sampling are required. The MAX108's flash architecture means conversion happens in a single clock cycle, making it one of the fastest ADC topologies available. Key specifications include 1.5 Gsps minimum sample rate, 2.2 GHz full-power input bandwidth, PECL (positive emitter-coupled logic) compatible digital outputs for low-jitter interfacing with FPGAs or high-speed ASICs, and integrated track-and-hold that eliminates the need for an external high-bandwidth sampler. The B-grade -B50105 suffix denotes the commercial temperature grade and the B50105 characterization/test option. The MAX108 uses an innovative differential flash architecture with on-chip calibration, providing low integral nonlinearity and aperture jitter. The integrated T/H holds the analog input stable during conversion, eliminating code-dependent aperture errors that plague many simpler flash designs. The internal PECL drivers deliver well-defined edges into 50 ohm loads, simplifying interface to high-speed FPGAs and demultiplexer ASICs. Typical applications include digital oscilloscopes, radar signal processing, direct RF digitization in software-defined radio, broadband test and measurement instrumentation, and high-energy physics data acquisition. The 2.2 GHz analog bandwidth makes the part suitable for undersampling IF signals as well as direct baseband sampling. When designing with the MAX108, use controlled-impedance differential signal traces for the analog inputs and matched-length PECL traces for the digital outputs to preserve the device's 1.5 Gsps performance. Decouple each supply pin with a separate 0.1 uF ceramic capacitor placed as close as possible to the BGA ball, and provide an external low-jitter PECL clock source meeting the device's aperture-jitter budget. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the standalone manufacturer datasheet, helping procurement and design engineers shorten evaluation cycles for this specialty ultra-high-speed ADC.
MAX108CHC-D - 1.5Gsps 8-Bit Ultra-High-Speed ADC ESBGA-192 | Maxim
The MAX108CHC-D from Maxim Integrated (now part of Analog Devices) is a PECL-compatible, 1.5Gsps, 8-bit ultra-high-speed analog-to-digital converter that enables accurate digitizing of analog signals with analog input bandwidths to 2.2 GHz. Housed in a 25 mm x 25 mm, 192-contact Enhanced Super Ball-Grid Array (ESBGA), the part is specified over the commercial 0C to +70C temperature range and is sampled at 1.5 billion samples per second. An ADC (analog-to-digital converter) is a semiconductor device that samples a continuous-time analog signal and quantizes each sample into a finite-resolution binary code, forming the critical bridge between the analog RF/IF front end and the digital signal processing back end. Within the converter family tree, the MAX108 belongs to flash ADC architecture -> high-speed ADC -> data converter -> signal chain IC. Flash ADCs use paralleled comparators to deliver single-cycle conversion, achieving the highest sampling rates available in monolithic silicon. Key features include ±0.25 LSB INL and DNL linearity, 7.5 effective bits at fIN = 750 MHz (Nyquist frequency), 50-ohm differential analog inputs, a PECL-compatible digital output interface, and an on-chip track-and-hold amplifier rated to 2.2 GHz full-power bandwidth. The device is fabricated on Maxim's proprietary GST-2 advanced bipolar process, allowing the track-and-hold and quantizer to coexist on a single monolithic die at multi-GHz analog speeds. The architecture pairs an innovative 2.2 GHz input T/H with an internally-latched flash quantizer core, which minimizes aperture uncertainty and eliminates the need for an external high-bandwidth sample-and-hold. This integrated approach simplifies board design, reduces component count, and shortens critical analog paths on the PCB—key for capturing repetitive single-shot events at sub-nanosecond timing accuracy. Typical applications include digital oscilloscopes, wideband test and measurement instrumentation, radar and EW (electronic warfare) IF digitizers, high-end spectrum analyzer capture front-ends, satellite communication receivers, and medical imaging systems such as ultrasound beamformers that require high analog bandwidth with moderate resolution. When designing with this device, note that the 192-ball ESBGA requires controlled-impedance PCB stackup, laser-via escape routing, and a solid ground/power plane beneath the die to deliver the rated 1.5 Gsps performance. Decoupling must include a ferrite bead plus 0.1uF/10uF/47uF capacitance placed within 5 mm of each supply pin to suppress switching noise from the PECL output drivers. This page synthesizes distributor pricing, drop-in alternatives, pin-out guidance, and practical PCB layout notes not found aggregated in the standalone datasheet, helping engineers shorten evaluation cycles for high-speed ADC prototyping.

An ADC (Analog-to-Digital Converter) is a mixed-signal integrated circuit that converts continuous analog voltages into discrete digital codes. SAR (Successive Approximation Register) ADCs use a binary-search algorithm with an internal DAC and comparator, offering an excellent trade-off between speed, accuracy, and power consumption for multi-channel data-acquisition systems. Within the broader taxonomy, the MAX1090BEEI belongs to successive-approximation ADCs -> data converters -> mixed-signal ICs -> signal chain -> semiconductor ICs. Key features include 400 ksps maximum sampling rate, 10-bit resolution, 8 single-ended or 4 differential input channels, an integrated +2.5V reference (4.0 V/V input range when using internal reference with 5 V supply), automatic hardware power-down between conversions, parallel-architecture start/stop control, and a high-speed byte-wide parallel output bus. The MAX1090 is the 8-channel variant in the 28-pin QSOP; the MAX1092 is the 4-channel variant in the 24-pin QSOP. The SAR core uses a charge-redistribution DAC with a precision comparator, and the integrated +2.5V reference eliminates the need for an external reference IC. The on-chip T/H (track-and-hold) supports input bandwidths suitable for multiplexed multi-channel acquisition, while the parallel interface simplifies connection to microcontrollers, DSPs, and FPGAs without requiring a serial-clock generator. Typical applications include industrial process-control and data-acquisition systems, portable instrumentation and battery-powered data loggers, medical instruments and patient monitors, multichannel sensor interfaces (temperature, pressure, strain), and automotive telemetry subsystems. The wide analog input range and parallel output are well matched to legacy 8-bit/16-bit MCU buses.

Designers should validate lifecycle status before committing to new designs. Refer to the manufacturer datasheet for full pinout, timing diagrams, and reference decoupling recommendations.
MAX1091ACEI+T - 250ksps 10-Bit 8-Ch ADC w/ 2.5V Ref | Maxim
The Maxim Integrated (Analog Devices) MAX1091ACEI+T is a 250 ksps, low-power, 10-bit, 8/4-channel analog-to-digital converter (ADC) with an on-chip +2.5V reference and a high-speed byte-wide parallel interface, housed in a 28-pin QSOP package. The device operates from a single +3V supply, features automatic power-down between conversions, and wakes up in 2 us, making it suitable for power-conscious multi-channel data-acquisition systems. The internal 2.5V reference eliminates the need for an external reference IC in typical applications. A successive-approximation register (SAR) ADC is a converter architecture that digitizes an analog input by performing a binary search through an internal precision DAC over one or more clock cycles per conversion. SAR ADCs are valued for their deterministic latency, low power consumption, no pipeline delay, and strong AC performance at moderate sample rates - characteristics that position them between flash converters (fastest, lowest resolution) and sigma-delta ADCs (highest resolution, slower). The MAX1091 belongs to the broader category of data converters / signal conditioning ICs within the analog semiconductor family. Its 8 single-ended or 4 pseudo-differential input channels, byte-wide parallel output, and integrated reference make it a complete system-level analog front-end for embedded designs. Key features include 8 analog input channels (configurable as 4 pseudo-differential pairs), a +2.5V internal reference, automatic power-down with 2 us wake-up, an internal conversion clock, and a high-speed byte-wide parallel digital interface. The +3V single-supply operation simplifies power tree design in 3.3V systems, and the auto-power-down function dramatically reduces average current draw in low-duty-cycle applications such as battery-powered instrumentation. The MAX1091 uses a classic SAR core with a sample-and-hold front end configured as MUX-S/H-ADC with a 1:1 input-to-ADC ratio. The high-speed parallel interface allows direct connection to microcontrollers, DSPs, or FPGAs without glue logic, while the internal reference removes a typical external component and PCB area. The 28-pin QSOP package balances compactness with hand-solder-friendly lead pitch, supporting both high-density and prototype builds. Typical applications include portable data loggers, multi-channel sensor interfaces (temperature, pressure, strain), industrial process control, patient monitors and point-of-care diagnostics, and optical encoders. The combination of 10-bit resolution and 250 ksps throughput is well-matched to these mid-bandwidth, multi-channel systems where deterministic conversion timing is important. When designing with the MAX1091, ensure that the supply decoupling network (typically 0.1 uF ceramic in parallel with 4.7 uF bulk) is placed within a few millimetres of the AVDD and DVDD pins. Use the internal reference (REF bypassed with 0.1 uF) unless absolute accuracy below +/-1 LSB is required - in that case, drive REF with an external low-drift reference and account for that reference's settling behavior at full sample rate.
