MAX116CAX - 12-Bit, 2x4-Ch Simultaneous-Sampling ADC | Maxim
MAX116CAX

MAX116CAX - 12-Bit, 2x4-Ch Simultaneous-Sampling ADC | Maxim

The Maxim Integrated (now Analog Devices) MAX116CAX is a 12-bit, 2x4-channel, simultaneous-sampling analog-to-digital converter (ADC) housed in a 36-pin SSOP (CAX) package with industrial temperature grading and gull-wing leads. It integrates four sample-and-hold (T/H) amplifiers that acquire two multiplexed inputs each, providing eight single-ended channels total, and supports throughput of 390 ksps at 1 active channel, scaling down to 116 ksps when all four channels are sampled simultaneously. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that converts continuous analog voltages into discrete digital codes, and the simultaneous-sampling sub-category specifically uses one SAMPLE-and-hold per channel so that all channels are captured at the exact same instant. This is in contrast to multichannel ADCs that use a single shared SAMPLE-and-hold and sequentially scan channels - which introduces time skew between channels. Simultaneous-sampling ADCs sit hierarchically inside the data-converter IC family, which itself belongs to the broader mixed-signal / data acquisition (DAQ) IC category, ultimately under power management and signal-chain semiconductors. Key features of the MAX116CAX include a 2 microsecond per-channel conversion time, 8 single-ended analog inputs organized as two 4-channel multiplexed banks, an industry-standard successive-approximation register (SAR) architecture, a 36-pin SSOP surface-mount package, and industrial (-40C to +85C) operating temperature range. The successive-approximation architecture provides deterministic latency and inherent robustness in noisy industrial environments compared to delta-sigma converters that require complex digital filtering. The MAX116CAX uses an SAR core clocked from an external crystal or clock source, with an internal reference and channel-selection logic. Four matched track-and-hold blocks feed the SAR core via an internal analog multiplexer, allowing all four channels to be digitized in one conversion cycle with no inter-channel timing skew. This architecture is critical for phase-sensitive applications such as power-line monitoring, motor control, and multi-phase vibration analysis where the relative amplitude and phase between signals carries the engineering meaning. Typical applications include three-phase power monitoring and metering, motor control current/voltage sensing, multi-axis inertial and vibration measurement, industrial process control multi-channel DAQ, and instrumentation requiring correlated multi-channel sampling. Engineers select this part when phase coherence between channels matters more than raw single-channel speed. Design considerations include providing adequate bypass capacitance on AVDD/DVDDDVDDVDD rails, ensuring the analog inputs remain within the common-mode range of the track-and-hold amplifiers, and respecting the aperture-time matching spec between channels. The 36-pin SSOP package has moderate thermal resistance suitable for industrial environments but should be paired with a ground plane for digital-noise isolation. This page synthesizes distributor pricing, parametric comparison, drop-in alternatives, and practical design notes for the MAX116CAX that go beyond the manufacturer datasheet alone.

MAX116EAX

MAX116EAX - 2x4-Channel 12-Bit Simultaneous-Sampling ADC | Maxim

The Maxim Integrated MAX116EAX is a 2x4-channel, simultaneous-sampling 12-bit analog-to-digital converter (ADC) housed in a 36-pin SSOP package. It integrates four track-and-hold amplifiers with two multiplexed inputs (eight single-ended inputs total), supports throughput up to 390 ksps on a single channel, and delivers 2 us conversion time per channel with a successive-approximation architecture. What is a simultaneous-sampling ADC? A simultaneous-sampling ADC is a converter that captures multiple analog input channels at exactly the same instant using per-channel track-and-hold (T/H) amplifiers, then digitizes them sequentially through a single ADC core. This preserves the relative phase information between channels - critical in motor control, three-phase power, multi-axis vibration and synchronized instrumentation applications where skew between channels would corrupt measurement. The simultaneous-sampling topology sits within the broader data-acquisition IC family, which itself falls under signal-chain ICs in power and signal management. Key features of the MAX116EAX include 2 us per-channel conversion time, a +5V single supply, internal 2.5V reference (with external override option), software-configurable unipolar/bipolar input ranges, and an industrial operating temperature range of -40 C to +85 C. Throughput degrades gracefully with active channels: 390 ksps (1 ch), 218 ksps (2 ch), 152 ksps (3 ch), and 116 ksps (4 ch). The architecture pairs four dedicated T/H amplifiers ahead of an input mux and a 12-bit SAR ADC. Each T/H captures a sample at the same acquisition clock edge; the mux then sweeps the held voltages sequentially into the SAR core, producing 12-bit results with no inter-channel skew between acquisition instants. Software mode selection sets channel count, input range, and power-down behavior. Typical applications include three-phase motor current sensing, multi-axis vibration and motion analysis, synchronized instrumentation in industrial process control, and multi-channel data-acquisition front-ends. Engineers select it when phase-accurate sampling across channels matters more than raw single-channel throughput. When designing in this part, ensure the analog inputs remain within the configured input range and that the host allocates enough acquisition time for the maximum channel count at the desired throughput. The internal reference can be bypassed for an external reference when system accuracy demands tighter drift performance than the internal 2.5V source provides.

MAX116EAX+ - 12-Bit 8-Channel Simultaneous-Sampling ADC | Maxim

The Maxim Integrated (now Analog Devices) MAX116EAX+ is a 2x4-channel, simultaneous-sampling 12-bit analog-to-digital converter (ADC) housed in a 36-pin SSOP package, designed for multi-channel data acquisition systems requiring synchronized sampling. It integrates four track-and-hold (T/H) amplifiers with two multiplexed inputs per T/H, providing eight single-ended analog inputs total, and supports throughput rates of 390 ksps (1 channel), 218 ksps (2 channels), 152 ksps (3 channels), and 116 ksps (4 channels) with a 2 us conversion time per channel. What is an ADC? An analog-to-digital converter (ADC) is a semiconductor device that transforms continuous analog voltage signals into discrete digital codes suitable for processing by microcontrollers, DSPs, or FPGAs. The MAX116EAX+ belongs to the successive-approximation register (SAR) ADC family, which trades conversion speed for high resolution and low power consumption. In the broader signal-chain taxonomy, this part sits as: ADC -> data converter -> data acquisition IC -> mixed-signal semiconductor, serving as the bridge between analog sensors and digital processing. Key features include four true simultaneous-sampling T/H amplifiers that capture analog inputs at the same instant - critical for phase-sensitive measurements such as power-line monitoring, motor control, and vibration analysis where skew between channels would corrupt the measurement. The device operates from a single +5V analog supply and a +5V digital supply, includes an internal 4.096V reference, and provides a high-speed parallel interface for direct connection to microcontrollers or FPGAs. Architecturally, the MAX116EAX+ uses a successive-approximation conversion core with separate analog and digital grounds to minimize noise coupling. Each channel pair shares a T/H front-end that holds the input during conversion, and the two multiplexers per T/H let the user choose between two sources per channel without external switching. Power dissipation is approximately 50 mW during continuous conversion and drops to under 1 mW in software-programmed shutdown modes. Typical applications include multi-phase power-line monitoring, three-phase motor control feedback, vibration and modal analysis, sonar and acoustic beamforming, simultaneous multi-sensor data acquisition, and industrial process control. The simultaneous-sampling architecture is the defining feature for any application where the relative phase between channels carries information. When designing with this part, route the analog and digital ground planes separately and join them at a single point under the IC's GND pin. Use 0.1 uF ceramic bypass capacitors within 5 mm of each supply pin, and consider an external reference if absolute accuracy better than the internal 4.096V drift allows is required. This page synthesizes distributor pricing, drop-in alternative candidates, and practical design notes not consolidated in the manufacturer datasheet, helping engineers shorten selection time for multi-channel data acquisition designs.

MAX116EAX+T - 12-Bit 116ksps 8-Ch Simultaneous-Sampling ADC | Maxim

The Maxim Integrated MAX116EAX+T is a high-speed, multi-channel, 12-bit data-acquisition system (DAS) with simultaneous track-and-hold amplifiers, offered in a 36-pin SSOP package. It integrates a 12-bit 2us successive-approximation ADC, an internal +2.5V reference, a buffered reference input, and a 4-channel simultaneous-sampling T/H front end that preserves the relative phase information of the analog inputs. The -T suffix denotes tape-and-reel packaging, while +T is the lead-free RoHS-compliant reel option. A successive-approximation ADC (SAR ADC) is a type of analog-to-digital converter that uses a comparator and a binary-weighted DAC to step through bit decisions, one per conversion cycle, delivering accurate 12-bit conversions in a fixed number of cycles. SAR ADCs sit within the data-converter hierarchy alongside delta-sigma and pipeline ADCs, and they are favored in multi-channel industrial systems where deterministic latency and simultaneous sampling are required. The MAX116EAX+T occupies the data-acquisition-system sub-category, which combines an ADC with front-end signal conditioning in a single chip. Key specifications include a maximum throughput of 390 ksps for one channel, 218 ksps for two channels, 152 ksps for three channels, and 116 ksps for four channels, an 8 single-ended / 4 differential analog input configuration via two 4-channel muxes, a 2us conversion time per channel, and an operating temperature range of -40C to +85C. The internal +2.5V reference is trimmed to within 1.5% and can be overdriven with an external reference for gain or absolute-accuracy adjustments. The device draws a low supply current, supports a single +5V analog supply plus a +5V digital supply, and provides a high-impedance analog input stage. Architecture-wise, the four simultaneous-sampling T/H amplifiers let the user acquire four analog inputs at one instant, then convert them sequentially through the shared 12-bit SAR ADC without losing phase relationships. This is critical in three-phase power monitoring, vibration analysis, and motor-control applications where misalignment between channel samples would corrupt the result. The buffered reference input rejects reference-noise coupling from external loads. Typical applications include three-phase motor control and power-line monitoring, multi-axis vibration and motion analysis, industrial process control, data loggers, and instrumentation. The 36-pin SSOP package provides a compact footprint for dense multi-channel boards. When designing with this part, ensure the analog and digital supplies are well decoupled and that the input MUX bandwidth exceeds the input signal bandwidth to preserve settling accuracy.

MAX1177CCUP+ - 16-Bit 135ksps SAR ADC | 0-10V Input | Maxim Integrated

The Maxim Integrated MAX1177CCUP+ is a 16-bit, 135ksps, single-supply successive-approximation analog-to-digital converter (SAR ADC) with a true bipolar 0V to 10V analog input range, housed in a 20-pin TSSOP package. It combines a precision analog front-end, a factory-trimmed internal clock, automatic power-down, and a byte-wide parallel digital interface in a compact surface-mount footprint, delivering 16-bit resolution at sampling rates up to 135 kilosamples per second. An SAR ADC is a type of data-acquisition converter that uses a binary-search successive-approximation algorithm to digitize an analog input. SAR ADCs occupy the middle ground between flash converters (very fast, low resolution) and sigma-delta ADCs (very high resolution, slower). They are widely used in industrial control, instrumentation, and data-acquisition systems where moderate speed (tens to hundreds of ksps) and true 16-bit resolution with low-latency deterministic conversion are required. The MAX1177 family belongs to the precision data-converter hierarchy that sits between slow integrating ADCs and high-speed pipeline ADCs. Key features include a bipolar ±5V or unipolar 0V-to-10V analog input range (the bipolar -5V to +5V mode is selected by pin configuration on the MAX1177/MAX1178/MAX1188 family), automatic power-down between conversions for reduced average supply current, a factory-trimmed internal conversion clock eliminating the need for an external crystal, and byte-wide parallel output that interfaces directly to microcontrollers and DSPs without external glue logic. The 20-pin TSSOP footprint provides a small board area suitable for space-constrained designs. Typical applications include industrial process control loops, weigh-scale signal chains, multi-channel data-acquisition front ends, panel meters and digital multimeters, motor control current/voltage sensing, and battery test equipment where the ADC directly digitizes ±10V transducer outputs. The internal input protection and the +4.2V analog input range make it well suited for industrial sensor interfacing. When designing with this part, place 0.1µF decoupling capacitors close to AVDD and DVDD, route digital outputs away from the analog input trace, and avoid switching large currents near the analog front-end. The MAX1177 differs from the MAX1178 and MAX1188 primarily in analog input range, so verify your signal-conditioning range matches the chosen variant.

The Maxim Integrated MAX1177CCUP+T (Analog Devices) is a 16-bit, 135 ksps, single-supply successive-approximation analog-to-digital converter (SAR ADC) with an integrated track-and-hold, automatic power-down, factory-trimmed internal clock, and a byte-wide parallel interface, housed in a 20-pin TSSOP package (MO-153AC). Key headline specifications include 16-bit resolution, 135 ksps maximum sample rate, single 4.2V analog supply, and true-bipolar analog input capability (per the MAX1177/MAX1178/MAX1188 family datasheet from Analog Devices). A successive-approximation ADC is a type of data converter that performs bit-by-bit comparisons against a precision DAC to determine the digital representation of an analog input signal. SAR ADCs combine low power consumption, deterministic latency, and no-pipeline-delay conversion - attributes that place them in the data converter hierarchy alongside pipeline and sigma-delta ADCs. The MAX1177 belongs to the successive-approximation converter family, which is part of the broader analog-to-digital converter category under data acquisition and signal chain ICs. Differentiating features include bipolar analog input range on a single supply (eliminating the need for negative rails and level-shift circuitry), an automatic power-down mode that lowers IADC at lower throughputs, a factory-trimmed internal oscillator that removes external clock components, and a parallel byte-wide digital interface that simplifies connection to microcontrollers and DSPs. The TSSOP-20 footprint is JEDEC-standard MO-153AC, allowing drop-in compatibility across the family and across the broader 20-pin TSSOP ADC landscape. Architecturally, the device uses a switched-capacitor charge-redistribution DAC for SAR conversion, an input track-and-hold stage with bandwidth sufficient for full-scale step inputs at the maximum conversion throughput, and digital control logic that sequences conversion, power-down, and bus handshaking. The bipolar input is achieved by on-chip level shifting of the input range relative to the analog supply, allowing true ±VREF bipolar measurements without external negative supplies. Typical applications include industrial process control data acquisition, multi-channel PLC analog input modules, precision sensor signal conditioning (load cell, strain gauge, pressure transducer), instrumentation front-ends, and portable/handheld measurement instruments. The automatic power-down and 135 ksps throughput support both multiplexed multi-channel scanning and single-channel high-resolution measurements. When designing with this device, place the supply bypass capacitors as close as possible to the AVDD and DVDD pins and ensure the reference voltage source has adequate drive strength and decoupling. The parallel interface timing must be respected in the microcontroller firmware, particularly the conversion-start and busy-flag handshake sequence documented in the datasheet.

The Maxim Integrated MAX1177CEUP+ is a 16-bit, 135ksps, low-power successive-approximation analog-to-digital converter (ADC) with a true bipolar 0 to +10V analog input range, housed in a 20-pin TSSOP (4.40mm body, MO-153AC) package. The single-supply +5V ADC integrates automatic power-down, a factory-trimmed internal clock, and a byte-wide parallel interface that simplifies connection to microcontrollers and DSPs. A successive-approximation register (SAR) ADC is a type of data converter that performs a binary search across an internal capacitive DAC, one bit per conversion clock cycle, to resolve the input signal against an internal or external reference. The MAX1177 belongs to the SAR ADC family within the data converter hierarchy, which also includes sigma-delta, pipeline, and flash architectures. SAR ADCs are preferred where low-latency sampling, single-shot conversion, and a simple synchronous interface are required - making them a workhorse of industrial control loops and instrumentation front ends. Key specifications of the MAX1177CEUP+ include a 135ksps sampling rate, 16-bit resolution with no missing codes, +/-1 LSB INL (typical), an internal +4.3V reference, and input overrange tolerant up to +18V (with series input resistor divider). The 0 to +10V true bipolar input eliminates the need for external signal conditioning in many industrial applications. The device draws 26.5mW (external reference) or 31mW (internal reference) at full throughput, and AutoShutdown reduces idle current to 0.4mA at 10ksps. Typical applications include industrial process control data acquisition, multi-channel PLC analog input modules, portable and battery-powered instrumentation, medical patient monitoring, and data loggers. The wide 0 to +10V input range directly accepts signals from industrial sensors and 4-20mA loop receivers terminated across a sense resistor. When designing with the MAX1177CEUP+, place 0.1uF and 10uF decoupling capacitors as close as possible to AVDD and DVDD, and provide a low-impedance ground plane.

MAX1177CEUP+T - 16-Bit 135ksps SAR ADC | Maxim | 20-TSSOP

The Maxim Integrated (Analog Devices) MAX1177CEUP+T is a 16-bit, low-power, successive-approximation (SAR) analog-to-digital converter (ADC) sampling at up to 135 ksps in a 20-pin TSSOP package. The single +4.75V to +5.25V analog supply operation, ±10V bipolar true-differential input range (when using external resistors), and factory-trimmed internal clock make it suitable for industrial process control, instrumentation, and data-acquisition front ends. The MAX1177CEUP+T consumes only 6.7 mW at 135 ksps and drops to 1.4 mW at 10 ksps, while automatic power-down between conversions reduces average power in low-duty-cycle applications. The byte-wide parallel digital interface simplifies connection to microcontrollers, microprocessors, and standard logic families without an external serial clock. A SAR ADC is a type of analog-to-digital converter that resolves a single bit per internal clock cycle using a switched-capacitor comparator and a precision DAC. Compared to delta-sigma and pipeline ADCs, SAR architectures deliver deterministic latency, no pipeline delay, and excellent DC linearity, which is why they dominate multiplexed multi-channel data-acquisition systems, closed-loop control loops, and precision sensor readouts. Key differentiating features of the MAX1177CEUP+T include ±0.5 LSB INL (typ), ±0.5 LSB DNL (no missing codes guaranteed), 84 dB SINAD at 10 kHz input, and an internal 4.096V reference that can be overdriven by an external source for ratiometric measurements. The TSSOP-20 package occupies less than 50 mm² of PCB area, while the input span can be programmed with two external resistors for unipolar 0-10V or bipolar ±10V, ±5V, 0-5V operation. The SAR architecture combined with the on-chip track-and-hold amplifier captures full-scale settling in 250 ns, enabling accurate sampling of multiplexed signals without an external front-end buffer in many designs. Byte-wide parallel output allows direct connection to 8-bit microcontroller buses or FIFO memories. Typical applications include industrial process control (4-20 mA loop readback after I/V conversion), multi-channel data-acquisition systems, portable instrumentation, and battery-powered sensor measurement front-ends where power-down between conversions minimizes idle drain. When designing with this device, ensure the analog and digital grounds are tied at a single star point under the IC to avoid digital switching noise coupling into the SAR comparator, and place the 10 µF + 0.1 µF bypass network within 5 mm of the AVDD pin. Sample-rate-dependent power dissipation must be evaluated against the TSSOP-20 84 °C/W θJA; for 6.7 mW typical dissipation the junction rise is well under 1 °C and a heatsink is unnecessary.

MAX1178BCUP+ - 16-Bit 135ksps Bipolar ADC ±5V | Maxim Integrated

The Maxim Integrated MAX1178BCUP+ is a 16-bit, 135 ksps, single-supply successive-approximation analog-to-digital converter (SAR ADC) that accepts a bipolar analog input voltage range of ±5 V, and is offered in a 20-pin TSSOP package with a factory-trimmed internal clock and AutoShutdown. It includes an internal +4.096 V reference option, ±5 V true bipolar input range on a single +4.2 V analog supply, and typical power dissipation of 26.5 mW at 135 ksps with external reference, 31 mW when using the internal reference. A SAR ADC is a successive-approximation-register converter, a category of medium-speed, low-latency analog-to-digital converters that perform one conversion per sample clock by stepping an internal DAC against the input through a binary-search algorithm. SAR ADCs sit between delta-sigma ADCs (which offer higher resolution at lower speed) and flash ADCs (which offer maximum speed at lower resolution), and they are widely used in industrial control, instrumentation, and data-acquisition front-ends where deterministic latency matters. Key features include ±5 V true bipolar input range on a single +4.2 V supply, automatic power-down that drops supply current to 0.4 mA at 10 ksps, 16-bit no-missing-codes performance, single-ended analog input with track-and-hold, and SPI/QSPI/MICROWIRE-compatible serial output. The MAX1178 family differs from the MAX1188 (±10 V input) and MAX1177 (±3 V input) by accepting the wider ±5 V bipolar input on the same TSSOP-20 footprint. Typical applications include industrial process control, data-acquisition front-ends for ±5 V sensor signals, weigh scales, vibration and motion analysis, and portable or battery-powered instrumentation. The AutoShutdown feature reduces system power by more than 90% in between-sample idle windows. When designing with this ADC, pay attention to the input clamping network for over-voltage protection and the reference decoupling scheme - the internal reference requires a low-ESR bypass cap of 4.7 µF or larger. For full ±5 V input swing, an external negative rail or a bipolar-input drive circuit is required at the analog input pin.

The Maxim Integrated MAX1178CEUP+T is a 16-bit, 135 ksps, single-supply successive-approximation analog-to-digital converter (SAR ADC) with a true bipolar analog input range, packaged in a 20-pin TSSOP (4.40 mm, MO-153) with tape-and-reel packaging. It accepts bipolar input signals directly, eliminating the need for external signal-conditioning op-amps or negative supplies in many industrial measurement applications, and operates from a single +4.75V to +5.25V analog supply. The 135 ksamples/s sample rate delivers approximately 84 dB of signal-to-noise plus distortion in a low-power architecture optimized for multiplexed data-acquisition front ends. A SAR ADC is a type of analog-to-digital converter that performs a binary search through an internal capacitive DAC to convert each input sample in a single conversion cycle, producing a settled 16-bit result with no pipeline latency. Unlike pipelined or delta-sigma ADCs, SAR converters are well suited to multiplexed multi-channel systems and DC measurements because every conversion is a complete, deterministic event. SAR ADCs sit within the broader category hierarchy of data converters -> ADCs -> successive-approximation ADCs -> semiconductor ICs, where they are the dominant choice for industrial instrumentation requiring both DC accuracy and fast channel-to-channel settling. Key features include 16-bit resolution (no missing codes), 135 ksps throughput, true bipolar ±VREF input range, single +5V supply operation, low power dissipation of approximately 30 mW at full throughput, and a parallel digital interface for direct connection to microprocessors, DSPs, or FPGAs. An on-chip +2.5V reference is included and is pin-overdrivable for ratiometric measurements, and the device includes a hardware power-down mode that reduces supply current to less than 10 uA between conversions. The device architecture combines an input signal scaler for bipolar-to-unipolar conversion, a precision sample-and-hold, a charge-redistribution DAC, and a digital comparator. An internal oscillator and trim capacitors remove external frequency-setting components, simplifying board layout. According to the manufacturer datasheet, the MAX1178 maintains ±1 LSB INL and ±1 LSB DNL over the commercial 0°C to +70°C operating range, with the bipolar input range enabling direct connection to ±5V or ±10V sensor outputs. Typical applications include industrial process control loops, multi-channel data-acquisition systems, portable instrumentation, and battery-powered measurement front ends where the bipolar input directly accepts ±5V or ±10V signals from transducers, thermocouples after amplification, or current-loop shunts. The hardware power-down mode also makes the device attractive for handheld meters that sample on demand to extend battery life. The parallel interface suits designs where an FPGA or DSP rather than a microcontroller handles the ADC handshake. When designing with this part, place the analog supply bypass capacitors as close to the AVDD pin as possible (typically 0.1 uF ceramic in parallel with 10 uF tantalum) and keep the analog and digital grounds separated until they join at a single star point beneath the IC. The +2.5V reference output requires a 0.1 uF to 1 uF low-ESR ceramic bypass capacitor directly on the REF pin. If the application requires ratiometric operation, drive REF with an external reference rather than using the internal source.

MAX1179ACUI+ - 16-Bit 135ksps Bipolar SAR ADC | Maxim Integrated

The Maxim Integrated MAX1179ACUI+ is a 16-bit, 135 ksps successive-approximation register (SAR) analog-to-digital converter with a true bipolar analog input range, supplied from a single +5 V rail. Housed in a 28-pin TSSOP package, this converter integrates an internal 4.096 V reference, an internal trimmed clock, and automatic power-down between conversions to minimize average supply current in low-duty-cycle applications. The MAX1179ACUI+ delivers 16-bit no-missing-codes performance, supporting industrial process control, instrumentation, and data-acquisition front-end designs where ±12 V or 0-5 V sensor signals must be digitized without external signal conditioning. What is a SAR ADC? A successive-approximation register analog-to-digital converter is a type of ADC that converts an analog input to a digital output using a binary-search algorithm against an internal DAC. Compared with sigma-delta ADCs, SAR converters achieve much higher sample rates (tens to hundreds of ksps) with no latency between sample and conversion, at the cost of lower resolution (typically 12-18 bits). SAR ADCs are widely used in industrial control loops, motor control, multiplexed data acquisition, and any application that demands deterministic one-shot conversion with simultaneous sampling capability. Key features of the MAX1179ACUI+ include 135 ksps maximum sample rate, ±10 V or 0 V to +5 V true bipolar input range (software configurable), internal precision 4.096 V reference, integrated sample-and-hold, parallel data output interface, and automatic power-down that reduces supply current to under 1 mA between conversions. The integrated reference eliminates an external component and guarantees specified accuracy across the full operating temperature range. The MAX1179ACUI+ offers an SINAD of approximately 86 dB and THD below -90 dB at the rated sample rate, supporting precision measurements in instrumentation applications. The MAX1179ACUI+ uses a charge-redistribution SAR architecture with input ESD protection diodes and an integrated front-end multiplexer. A factory-trimmed internal clock sets the conversion time, eliminating the need for an external ADC clock source. The device supports both unipolar (0 V to +5 V) and true bipolar (±10 V or ±5 V) input ranges through pin-strapping, which is unique in its class and eliminates external signal conditioning for industrial sensors with bipolar outputs. Typical applications include industrial process control loops, PLC analog input modules, portable instrumentation, data acquisition systems, and medical monitoring equipment. The wide ±10 V bipolar input range is particularly valuable for digitizing current-loop outputs from industrial transmitters without external resistor networks. Compared to discrete ADC + op-amp signal conditioning solutions, the MAX1179ACUI+ reduces BOM cost and PCB footprint significantly. When designing with this device, place the input bypass capacitor directly at AVDD and AGND pins to minimize digital coupling. The MAX1179ACUI+ requires careful PCB layout separating analog and digital grounds, with a single point connection near the ADC. The internal reference output should be decoupled with a 10 µF capacitor for specified noise performance.

MAX1179AEUI+ - 16-Bit 135ksps Bipolar SAR ADC | Analog Devices

The Analog Devices (formerly Maxim Integrated) MAX1179AEUI+ is a 16-bit, 135ksps, low-power, single-supply successive-approximation analog-to-digital converter (SAR ADC) with a true bipolar analog input range of ±5V (or 0 to +5V unipolar via internal reference), housed in a 28-pin TSSOP package. The converter combines a high-speed 135ksps sample rate with 16-bit resolution and low power dissipation, making it ideal for industrial process control, data acquisition, and instrumentation front-ends that must digitize bipolar sensor signals without external signal conditioning. A SAR (Successive Approximation Register) ADC is a precision data converter that performs a binary-search conversion on an internal capacitive DAC, producing a digital code that converges to the input voltage in N clock cycles for an N-bit converter. Within the broader product hierarchy, the MAX1179 sits as a precision ADC -> data converter -> signal chain IC -> mixed-signal semiconductor, and is differentiated from sigma-delta and pipeline ADCs by its single-shot latency (one conversion per trigger, no pipeline delay) and intrinsic ease of single-supply bipolar operation. Key features of the MAX1179AEUI+ include an internal 4.096V reference, an external reference option, a single-ended analog input, a parallel (16-bit wide) digital interface, and a hardware-/software-configurable input range. The device supports both unipolar (0 to +5V) and bipolar (-5V to +5V) input spans, with a single +4.2V analog supply and a +2.7V to +5.25V digital supply. A separate 50MHz conversion clock or external crystal is not required; the on-chip oscillator drives the SAR state machine. The TSSOP-28 package provides a small footprint suitable for high-density data-acquisition boards. The MAX1179 architecture uses a charge-redistribution capacitive DAC followed by a low-noise comparator and SAR logic. By accepting ±5V true bipolar inputs on a single 4.2V analog supply, the part eliminates the need for external level-shift or negative-rail circuitry that would otherwise be required to digitize AC sensor outputs, thermocouple or strain-gauge bridge signals, or industrial ±10V (after resistor divider) transducer outputs. Typical applications include industrial data-acquisition front-ends, PLC analog input modules, multi-channel instrumentation panels, weigh scales and load-cell digitizers, and motor-control feedback loops where a high-accuracy 16-bit conversion with simultaneous sampling of a bipolar transducer is required. When designing with this device, decouple AVDD and DVDD with 0.1µF and 10µF ceramic capacitors placed within 2mm of each supply pin, and route analog and digital grounds to a single-point star ground under the exposed pad to prevent digital return currents from corrupting the input signal. The reference bypass capacitor is critical: 4.7µF minimum directly on REF. This page synthesizes distributor pricing, drop-in alternatives from the MAX1179 family, and practical design notes not collated in the manufacturer datasheet, helping engineers shorten the selection-to-prototype cycle for 16-bit bipolar ADC designs.

MAX1179AEUI+T - 16-Bit 135ksps Bipolar-Input SAR ADC | Maxim Integrated

The Analog Devices (formerly Maxim Integrated) MAX1179AEUI+T is a 16-bit, 135 ksps, successive-approximation analog-to-digital converter (ADC) with a bipolar ±5 V analog input range, housed in a 28-pin TSSOP package. The single-supply 4.2V-to-5.25V device integrates an input signal-conditioning true-differential track-and-hold, an on-chip 4.096V reference, and a parallel digital interface, simplifying front-end design in industrial process control and instrumentation. A successive-approximation register (SAR) ADC is a class of Nyquist-rate data converter that performs a binary search through an internal capacitive DAC to converge on the input voltage one bit per conversion clock cycle. SAR ADCs are prized for their deterministic latency, inherent single-shot accuracy with no pipeline delay, and excellent DC linearity, which makes them the architecture of choice for multiplexed data-acquisition systems, motor control current sensing, and precision instrumentation. Key features include 135 ksps throughput, ±5 V (10 V p-p) true-bipolar analog input range from a single 5 V supply, ±18 V fault-tolerant analog inputs, 16-bit no-missing-codes performance, internal 4.096 V reference, software-configurable unipolar/bipolar input range, and a low 4.2 mA typical supply current. The internal reference eliminates an external precision reference and the associated drift budget. The MAX1179 uses an input track-and-hold followed by a charge-redistribution SAR core. The 135 ksps rate is sufficient for many multiplexed industrial loops, while the parallel interface minimizes host CPU overhead. Analog Devices' process and proprietary input-protection network enable ±18 V input survival without external clamping. Typical uses include industrial process control (4-20 mA loop digitization through a sense resistor), multichannel data-acquisition boards, portable or battery-powered medical instruments, and system-monitoring functions inside +24 V factory-automation equipment. When designing with this device, place a 0.1 µF bypass ceramic capacitor close to the supply pad, keep analog and digital grounds joined at a single point, and verify that the host parallel bus timing meets the tCONV and tACQ windows given in the manufacturer datasheet.

MAX1179BCUI+ - 16-Bit 135ksps Bipolar ADC | Maxim Integrated

The Maxim Integrated MAX1179BCUI+ is a 16-bit, 135ksps, single-supply successive-approximation analog-to-digital converter (SAR ADC) with a true bipolar analog input range, housed in a 28-pin TSSOP package. It operates from a single +5V analog supply, draws only 2.5mA in normal operation, and includes automatic power-down between conversions. An SAR ADC is a type of analog-to-digital converter that uses a successive-approximation register to perform binary search on the input voltage. SAR converters occupy the niche between slow, high-resolution sigma-delta ADCs (used for precision DC measurements) and fast, lower-resolution flash ADCs (used in oscilloscopes). Within the broader signal-chain hierarchy they sit alongside sample-and-hold amplifiers, input multiplexers, and voltage references; the part family here belongs to Maxim's data-conversion portfolio (ADC -> data converter -> mixed-signal IC -> semiconductor). Key features include a true bipolar ±12V (or 0 to +12V, user-selectable) input range without external signal conditioning, integrated track-and-hold, factory-trimmed internal clock, and a 16-bit parallel interface. The bipolar capability eliminates the front-end op-amp/inverter chain typically required to digitize signals centered around ground, simplifying industrial process-control and instrumentation designs. Internally, the device combines a capacitive-charge-distribution DAC with auto-calibration logic. Factory trimming removes offset and gain error at production, achieving ±1.5 LSB INL and ±1 LSB DNL typical, plus 86dB SINAD at 100kHz. The architecture supports single-shot conversions via the CONVST pin and offers throughput scalable down to 1ksps with proportional power savings (90 microamps at 1ksps). Typical applications include industrial process control (4-20mA loop digitization through a sense resistor), data-acquisition boards, pen plotters, and portable instrumentation. The bipolar input makes the MAX1179BCUI+ especially attractive in PLCs and motor-control feedback paths where signals swing around 0V. Design consideration: drive AIN through a low-impedance source (op-amp buffer or instrumentation amp) because the ADC's input draws 1 microamp of leakage and the input capacitance settles in microseconds; a 10kohm source impedance limits 16-bit settling. Provide a clean AGND and DGND split, joined only at one point near the ADC.

The Maxim Integrated MAX1179CCUI+T is a 16-bit, 135ksps, low-power, successive-approximation register (SAR) analog-to-digital converter (ADC) with a true bipolar analog input range, housed in a 28-pin TSSOP (4.40mm body width) package. It operates from a single +4.2V (nominal +5V) supply, accepts input spans from -5V to +5V, and integrates automatic power-down, a factory-trimmed internal clock, and a track-and-hold front-end. An SAR ADC is a type of data converter that performs a binary-search analog-to-digital conversion using a capacitive charge-redistribution DAC and a single comparator, achieving deterministic latency and excellent DC accuracy without the pipeline delay or switching-ripple artifacts common to delta-sigma and pipeline ADCs. SAR ADCs sit within the broader analog-to-digital converter hierarchy (SAR -> ADC -> data converter -> mixed-signal IC -> semiconductor) and are favored for multiplexed acquisition, industrial control loops, and portable instrumentation because each conversion completes in one acquisition cycle. Key features include ±5V bipolar input range on a single supply, throughput up to 135k samples per second, low power dissipation with automatic power-down between conversions, a serial interface for compact PCB routing, and a commercial 0°C to +70°C operating grade. The integrated track/hold and factory-trimmed internal clock eliminate several external components typical of older 16-bit SAR designs, simplifying BOM and shrinking the analog front-end footprint. The MAX1179 architecture uses a charge-redistribution DAC array and a precision comparator controlled by successive-approximation logic, yielding ±1 LSB INL (max) and no missing codes over the full 16-bit range. Bipolar input conditioning is handled by an on-chip input scaling network that derives ±5V range from the +5V supply rail without a negative supply, a meaningful simplification over legacy bipolar ADCs that required ±12V rails. Typical applications include process control and industrial data acquisition cards, portable instrumentation and weigh scales, motor control feedback loops, and medical patient-monitoring front-ends. The bipolar input particularly suits PLC analog input modules that must read 4-20mA or ±10V process signals directly. When designing with this part, place the 0.1µF decoupling capacitor within 5mm of the AVDD pin and provide a solid ground pour under the package to keep the track/hold acquisition clean. Avoid routing the serial interface traces parallel to noisy digital lines; this ADC samples at sub-microsecond rates and is sensitive to digital-to-analog coupling.

MAX117CAI+ - 8-Channel 8-Bit 400ksps ADC | Maxim

The Maxim Integrated MAX117CAI+ is an 8-channel, 8-bit, microprocessor-compatible flash analog-to-digital converter with a 400 ksps conversion rate, 1.8 µs conversion time, and operation from a single +3 V supply. The device is housed in a 28-pin SSOP package and features eight single-ended analog inputs, a parallel output interface, and a low-power shutdown function. A flash ADC is a sampling data-conversion IC that compares its analog input against an internal reference ladder and directly produces a digital output. The MAX117 belongs to the ADC category within data-converter ICs and broader semiconductor hierarchy. Its parallel architecture allows a microprocessor or digital controller to read each conversion result directly, making it useful for multichannel industrial monitoring, control, instrumentation, and embedded systems where several relatively slow sensor signals must be digitized. The MAX117CAI+ converts at 400 ksps and uses a half-flash technique to achieve a 1.8 µs conversion time. Its PWRDN input reduces supply current to 1 µA typical for low-duty-cycle or portable equipment. A logic high on PWRDN wakes the converter to normal operation in less than 900 ns. The input and reference arrangement supports ratiometric operation, in which the converter follows the ratio between the measured input and its reference voltage. Eight single-ended inputs provide the device with a practical advantage over single-channel ADCs in multichannel systems. Parallel output reduces the number of serial-clock cycles required after conversion, although it requires more connection paths between the ADC and the controller. The 28-pin SSOP package is suitable for through-hole assembly and is substantially larger than modern leadless packages, making board area an important design consideration. Typical applications include temperature and pressure monitoring, industrial process control, battery-cell measurement, discrete sensor acquisition, laboratory instrumentation, and embedded control systems. For designs requiring higher resolution, more channels, or a more compact package, the MAX113/MAX117 family should be checked for the appropriate channel count and package variant. Design around the specified +3 V supply, external reference behavior, conversion timing, and parallel data interface. Decoupling should be placed close to the supply and reference pins, while unused inputs and control pins should be connected according to the manufacturer pin-description table. Input signals must remain within the device's specified analog input range. This product page consolidates the converter's core specifications, package information, application guidance, design considerations, and the documented drop-in option into an engineering-focused reference. It also distinguishes the MAX117CAI+ from the closely related MAX117CAI+T ordering code so procurement teams can identify the correct manufacturer suffix.

MAX117CPI - 8-Channel 8-Bit 400ksps ADC | Analog Devices

The Analog Devices MAX117CPI is an 8-bit, 8-channel, microprocessor-compatible analog-to-digital converter with a 400 ksps conversion rate and a 28-pin through-hole DIP package. It operates from a single +3 V supply, uses half-flash conversion, and supports power-down operation. An ADC is a data-conversion IC that translates an analog input voltage into a digital code for processing, measurement, or control. The MAX117 belongs to the ADC hierarchy, where flash ADCs use parallel or semi-parallel internal comparison stages to support relatively high sampling rates. Its eight inputs make it useful when a system must monitor several analog signals through one converter rather than using a separate ADC for each channel. Key characteristics include 8-bit resolution, eight analog inputs, a maximum sampling rate of 400 ksps, and a conversion time of 1.8 microseconds. The MAX117CPI uses a +3 V supply, provides microprocessor-compatible interfacing, and includes a power-down function. These features suit compact control and measurement systems where low supply voltage, multiple inputs, and straightforward digital interfacing are more important than high-resolution conversion. The half-flash architecture provides a practical balance between conversion speed and implementation complexity. At 400 ksps, one conversion can nominally occupy 1.8 microseconds before software or hardware overhead is added. An 8-bit converter represents each analog input with one byte of digital data, which is appropriate for threshold monitoring, switch-position decoding, simple sensor measurement, and supervisory control functions where additional resolution would not materially improve the system result. Typical uses include industrial control panels, battery-operated instruments, digital thermometers, multichannel sensor interfaces, automotive accessory modules, and embedded monitoring systems. The eight inputs can support several resistive sensors, discrete thresholds, or mixed analog signals sharing a common measurement front end. The MAX117 is especially relevant where the host processor requires a simple parallel ADC interface rather than a serial data-conversion protocol. Designers should confirm signal-range compatibility, supply sequencing, acquisition timing, and input-signal settling before committing the eight analog channels to a board. Input conditioning may be required when sources exceed the converter's input range or drive the inputs too slowly for the selected sampling rate. Digital interface timing and reference behavior must also be checked against the manufacturer's pin-description table. This product page consolidates the converter's principal electrical characteristics, verified package information, drop-in family options, and application-oriented design guidance. It is intended to shorten component selection while keeping the final circuit decisions with the engineer and the manufacturer datasheet.

It operates from a single 3 V supply and is housed in a 28-pin SSOP package. A low-power shutdown mode reduces supply current to 1 µA, making the converter suitable for portable and intermittently powered measurement systems. An analog-to-digital converter, or ADC, converts an analog voltage into a numeric code for processing by a microcontroller, logic circuit, or display controller. The MAX117EAI+ belongs to the flash-converter family of ADCs, combining a sampling architecture with parallel digital outputs. Eight channels allow one converter to monitor multiple sensors, potentiometer positions, or control signals while retaining a direct microprocessor interface. Key operating characteristics include an 8-bit resolution, eight analog inputs, and a maximum conversion rate of 400 ksps. The converter uses a half-flash technique to achieve its 1.8 µs conversion time. Its single 3 V supply operation simplifies power architecture, while the 1 µA shutdown current helps reduce energy use when the measurement system is inactive. The parallel output interface exposes the converted value to external digital circuitry and supports microprocessor-compatible system designs. The 28-pin SSOP package is suitable for through-hole assembly and conventional PCB layouts. Because resolution is 8 bits, each ideal conversion code represents one of 256 output levels, making the device appropriate for control, monitoring, and display applications that do not require higher precision. Typical uses include industrial sensor interfaces, digital potentiometer and potentiometer emulation, panel controls, process monitoring, and embedded control systems. Multiple analog channels can reduce the number of separate converter packages when several low-bandwidth measurements must be acquired. The 400 ksps rate is especially useful when the system needs to update several measured values rapidly. Designers should verify the analog input range, conversion timing, acquisition requirements, and digital interface timing in the manufacturer datasheet before finalizing the PCB. The supply and reference paths require appropriate bypassing, and unused analog inputs should be handled according to the device guidance. The low-power shutdown function should be controlled so that settling and acquisition timing remain valid after wake-up. This product page combines the known operating specifications, package information, replacement guidance, and application-oriented design considerations for engineers evaluating the MAX117EAI+.

The device is specified as an 8-bit ADC with four channels and a 400ksps throughput rate. Its input architecture and converter throughput are intended for industrial monitoring, digital panel meters, process-control loops, and embedded data acquisition. Because it accepts several analog signals, it can reduce component count and simplify routing on a board that must monitor multiple transducers or potentiometer positions. Package and environmental details distinguish this industrial-grade, through-hole ordering code. The MAX117EPI is packaged in a rectangular 28-pin DIP and is identified as industrial temperature grade. Its 762mW maximum power dissipation and single-supply architecture make it most appropriate for conventional 3V embedded systems rather than ultra-low-power battery products.

The device provides eight single-ended analog inputs and a parallel output interface for direct connection to a microprocessor or other digital controller. Its active-low PWRDN control reduces supply current to typically 1 µA, while recovery from power-down mode occurs in less than 200 ns. An ADC is an analog-to-digital converter, a semiconductor interface that transforms continuously varying analog voltages into numerical values suitable for digital processing. The MAX118 belongs to the parallel-interface ADC family within the broader data-converter and signal-processing semiconductor hierarchy. It is intended for systems where multiple analog inputs must be measured quickly, but higher resolution is not required. The MAX118 family is particularly suitable for industrial monitoring, control systems, data acquisition, and embedded instrumentation where a parallel bus simplifies connection to a processor.

It uses a half-flash conversion architecture to achieve a stated conversion time of 660 ns, while an active-low power-down input reduces shutdown current to typically 1 µA. The parallel interface allows direct connection to an 8-bit microprocessor or digital bus. An ADC converts continuously varying analog voltages into numeric values that digital control systems can process. The MAX118 belongs to the data-converter hierarchy: analog-to-digital converter, ADC, data converter, and integrated circuit. Its eight single-ended inputs make it suitable for monitoring multiple sensors, control signals, or measurement channels without requiring eight separate converter packages. Its 8-bit resolution provides 256 digital codes across each input range. The principal features are eight single-ended inputs, 8-bit resolution, a 1 MSPS conversion rate, and a 660 ns half-flash conversion time. The converter operates from one +5 V supply, with the listed operating range extending from 4.75 V to 5.25 V. Its parallel output architecture supports microprocessor-compatible interfacing, while the active-low power-down function provides a low-current shutdown state. The 28-pin PDIP package supports conventional through-hole PCB assembly. The half-flash architecture forms the central technical basis of the converter. Rather than waiting for a complete conversion cycle before the next sample can begin, the architecture supports successive conversion operation at the stated 1 MSPS rate. This behavior is useful when several analog inputs must be refreshed quickly for control, display, or measurement functions. Signal conditioning, source impedance, and input-range selection still require attention because ADC performance depends on the complete analog path, not only the converter IC. Typical uses include industrial process monitoring, laboratory measurement, data logging, embedded instrumentation, and legacy control-system analog input modules. Eight channels can reduce the component count and board area when several slow or moderate-speed signals share a common sampling system. The MAX118CPI+ is also appropriate where an existing parallel-bus processor expects an 8-bit conversion result and a +5 V interface rather than a serial data link. For PCB implementation, reserve all 28 package positions and route the parallel data bus away from high-current switching nodes. Place the device close enough to the analog inputs to minimize trace pickup, and use suitable input conditioning when sensor outputs exceed the converter input range. Confirm signal levels, timing margins, and acquisition sequencing against the manufacturer pin-description and timing information before releasing the layout. This page combines the MAX118CPI+ electrical identity, procurement fields, comparison guidance, and engineering-oriented design notes in one searchable reference. It also distinguishes the confirmed 28-pin PDIP variant from unverified substitutes so engineers can focus on verified function, package, timing, power, and interface constraints.

Its single +5V operation simplifies power-supply design in legacy and industrial equipment. The half-flash architecture is specifically intended to combine rapid conversion performance with microprocessor-compatible operation. An active-low power-down input permits the converter to remain at approximately 1µA when it is not needed and supports recovery to normal operation in less than 200ns. The MAX118 family is offered in four-channel and eight-channel versions. The MAX118EPI+ is the eight-channel industrial-grade version in a 28-pin PDIP package. Its through-hole package supports legacy control boards and systems assembled with socketed or perforated-board construction. The parallel architecture makes the device particularly relevant to older industrial controllers, data acquisition instruments, and embedded systems that use direct digital input lines rather than SPI, I2C, or other serial ADC interfaces. Typical uses include eight-channel sensor acquisition, process monitoring, laboratory measurement, industrial control, and legacy data logging. Eight analog channels can be sampled for temperature, pressure, position, or analog instrumentation signals, provided each signal remains within the device's supported input range and the system provides suitable conditioning. The 1MSPS conversion rate supports faster-changing events than a slow general-purpose system ADC while retaining a simple eight-bit parallel data path. Designers should verify the complete pinout, input ranges, acquisition timing, and digital interface behavior against the manufacturer datasheet before layout or firmware work. Analog signal routing should minimize noise and crosstalk, while adequate bypassing should be placed close to the supply pins. Because this is a legacy parallel-interface converter, replacement decisions must consider not only resolution, speed, and channel count but also exact pin compatibility, logic levels, and timing. This page combines manufacturer specifications, distributor pricing and availability data, same-family replacement information, and practical migration guidance. It distinguishes verified drop-in candidates from broader functional similarities so engineers can evaluate MAX118EPI+ replacements without confusing package compatibility with complete electrical equivalence.

MAX11903ETP+T - 18-Bit 1.6Msps SAR ADC | Analog Devices

The Analog Devices MAX11903ETP+T is an 18-bit, 1.6 Msps, single-channel, fully differential SAR analog-to-digital converter with internal reference buffers, offered in a 20-pin TQFN (4 mm x 4 mm) package. Key headline parameters include 18-bit resolution, 1.6 Msps maximum sampling rate, and a fully differential ±VREF input range. The device communicates via an SPI-compatible serial interface and is specified over the -40 °C to +85 °C industrial temperature range. A SAR (Successive-Approximation Register) ADC is a class of Nyquist-rate converter that resolves one bit per internal clock cycle using a capacitive charge-redistribution DAC and a comparator. SAR ADCs sit at the boundary between precision (sigma-delta) and high-speed (pipelined/folding) converters, combining low latency (one conversion cycle), deterministic behavior, and excellent DC accuracy without the digital decimation filters of sigma-delta parts. They are the workhorse for multiplexed data-acquisition systems, industrial sensors, and digital control loops where single-shot latency matters. The MAX11903ETP+T delivers best-in-class power consumption that scales linearly with throughput, meaning current draw at 100 ksps is roughly 1/16 of the current at 1.6 Msps. Internal reference buffers eliminate the need for external high-current reference drive circuitry, simplifying the BOM and reducing PCB area. The unipolar differential ±VREF input range allows direct interface to bridge sensors, current-shunt monitors, and differential audio signals after scaling. Internally, the device uses a 1.8 V analog core supply plus a 3.3 V reference-buffer supply; the split rail minimizes digital noise coupling into the sensitive analog front-end. An integrated high-impedance input structure accepts true bipolar differential signals when biased around a common-mode voltage, supporting direct connection to bridge sensors and instrumentation outputs. Typical applications include precision industrial data acquisition, weigh scales and load-cell digitizers, motor-control current sensing, medical instrumentation signal chains, and multi-channel multiplexed sensor systems. The serial SPI-compatible output and small TQFN footprint make it equally at home in dense multi-channel boards. When designing with this ADC, take care with the reference decoupling: place 10 µF ceramic + 0.1 µF NF bypass right at the REF pins and use a star-ground topology to keep digital return currents out of the analog ground. Input common-mode biasing matters - set IN+ and IN- around VREF/2 for maximum dynamic range on differential signals. This page synthesizes distributor pricing, drop-in alternatives drawn from the Site MPN list, and practical design notes that go beyond the manufacturer datasheet's electrical tables alone.
