LTC2393ILX-16 - 16-Bit 1Msps SAR ADC 94dB SNR | Analog Devices
The Analog Devices LTC2393ILX-16 is a 16-bit, 1Msps successive-approximation-register (SAR) analog-to-digital converter with 94 dB SNR, offered in a 48-pin LQFP (7x7 mm) industrial-temperature package. It integrates a precision internal reference (0.5% initial accuracy, ±20 ppm/°C max drift), a high-performance sample-and-hold, and both parallel and serial digital interfaces, all in a single chip. The device operates from a 5V analog supply and 2.5V to 5.25V digital I/O supply. A SAR ADC (successive-approximation-register analog-to-digital converter) is a type of Nyquist-rate data converter that resolves one bit per internal clock cycle using a binary-search algorithm against a precision DAC and comparator. SAR ADCs occupy the middle ground between flash converters (very fast but power-hungry and low resolution) and sigma-delta converters (very high resolution but limited to lower input bandwidth). The LTC2393ILX-16's 1 Msps throughput with no pipeline latency makes it ideal for multiplexed data acquisition, control loops, and instrumentation where deterministic single-cycle conversion latency is required. Key features include 94 dB SNR, 90 dB THD, ±2 LSB INL typical, and a wide input common-mode range. The internal reference eliminates external reference drift and layout burden, while the dual-interface (parallel + serial) gives PCB designers flexibility. The part supports daisy-chained readout on the serial interface, simplifying multi-channel designs. Typical aperture delay is well controlled for synchronous sampling. Architecture-wise, the LTC2393 uses a charge-redistribution DAC array and an internal low-noise reference buffer, with on-chip calibration logic that corrects capacitor mismatch at power-up. The combination of 1 Msps real sampling rate and 16-bit resolution delivers SNR figures approaching sigma-delta performance without the latency penalty, making the LTC2393ILX-16 a benchmark for precision industrial and instrumentation designers. Typical applications include industrial process control and data acquisition, precision weigh scales and force-meters, motor control feedback, vibration and acoustic analysis, and medical instrumentation front ends. The wide operating temperature range and integrated reference simplify designs where PCB area and component count matter most. Design consideration: ensure the analog and digital grounds are tied at a single star point beneath the IC. Bypass the AVDD and DVDD pins with 10 µF + 100 nF vacuum decay (VDEC) capacitors placed as close as possible to the package. The internal reference eliminates the need for an external REF, but the REFCOMP pin still needs a 10 µF hold capacitor for noise filtering.

LTC2393IUK-16 - 16-Bit 1Msps SAR ADC, 94dB SNR | Analog Devices
The Analog Devices LTC2393IUK-16 is a low-noise, high-speed 16-bit successive approximation register (SAR) analog-to-digital converter with 1Msps throughput and 94dB SNR, housed in a 48-lead QFN (7x7 mm, UK suffix) package. Operating from a single 5V analog supply, the part accepts a large fully-differential input range of plusmn 4.096V, making it well-suited to high-performance applications that demand maximum dynamic range per channel. The IUK-16 industrial-grade variant (operating from -40C to +85C) is supplied in a UK package finish compatible with the LTC2392 and LTC2391 SAR ADC families. What is a SAR ADC? A successive approximation register analog-to-digital converter is a precision data-conversion topology that performs one bit per clock cycle using a binary-search algorithm against an internal DAC. SAR ADCs sit in the taxonomy between flash converters (fastest, lowest resolution) and delta-sigma ADCs (slowest, highest resolution), occupying the sweet spot of 12-20 bits at 0.1-10 Msps with no latency and deterministic behavior - ideal for multiplexed data acquisition, motor control, and instrumentation. Key specifications include 94dB SNR at 1Msps for high dynamic-range capture, an internal precision reference with 0.5% initial accuracy and plusmn 20ppm/C (max) temperature coefficient that eliminates external reference components, plus both parallel and serial (SPI-/QSPI-/MICROWIRE-compatible) interface modes selected at power-up via the PAR/SER pin. The device draws approximately 14 mW active power at 1Msps and offers nap and sleep modes that bring quiescent consumption into the microamp range for battery-friendly operation. Architecturally, the LTC2393-16 uses a charge-redistribution DAC array with input sampling on dedicated fully-differential SWCAP front-ends, allowing common-mode rejection above 80 dB and preserving linearity across the full plusmn 4.096V differential input range. An integrated reference buffer drives the SAR core without requiring an external reference amplifier, simplifying the analog front end for both AC- and DC-coupled signal chains. Typical applications span precision industrial data acquisition, weigh scales and strain-gauge digitizers, process-control loopback I/O, high-speed medical instrumentation, vibration and seismic monitoring, and multi-channel multiplexed sensor front ends where its low latency and wide input range minimize front-end signal conditioning. When designing with the LTC2393IUK-16, ensure the analog and digital grounds meet only at the exposed pad, place 10uF + 0.1uF decoupling as close as possible to the AVDD/DVDD pins, and confirm the PAR/SER strapping option matches the host MCU/DSP/FPGA interface width before board bring-up. The optional CNVST-driven burst mode is useful when synchronizing multiple LTC2393s to a shared external clock.

LTC2415IGN - 24-Bit No Latency Delta Sigma ADC | Analog Devices
The Analog Devices LTC2415IGN is a 24-bit no-latency delta-sigma analog-to-digital converter with differential input and differential reference, housed in a 16-pin SSOP package. It delivers 2 ppm INL, 0.23 ppm RMS noise, and operates from a 2.7 V to 5.5 V supply while drawing only microamp-level quiescent current. A 24-bit delta-sigma ADC is a high-resolution converter that uses noise shaping and oversampling to achieve very high effective resolution at low sample rates. Delta-sigma ADCs are widely used in precision measurement, weighing scales, industrial process control, and temperature monitoring because they integrate a digital filter, modulator, and reference input in a single IC. Within the broader hierarchy, the LTC2415 belongs to the precision ADC category, itself part of the data converter product family under Analog Devices' signal-chain portfolio. Key features include differential input common-mode voltage V(INCM) and differential reference common-mode voltage V(REFCM) that can be independently set anywhere between GND and VCC, enabling true ratiometric measurements. The single-pin mode selection offers better than 110 dB input differential-mode 50 Hz / 60 Hz noise rejection, while the integrated oscillator eliminates the need for an external clock crystal. The serial SPI / MICROWIRE-compatible interface simplifies connection to microcontrollers, FPGAs, and digital isolators. The converter achieves single-cycle settling, which makes it suitable for multiplexed applications where input channels are switched between measurements. The integrated digital filter rejects line frequency noise by more than 110 dB in the 50 Hz / 60 Hz common-mode rejection mode, a key requirement for weighing scales and process instrumentation. The 0.23 ppm RMS noise floor and 2 ppm INL specification provide true 24-bit effective resolution for DC measurements. Typical applications include precision weighing scales, industrial process control, strain-gauge transducers, thermocouple and RTD temperature measurement, and battery-cell voltage monitoring. The differential input structure makes the part well-suited to bridge-sensor signal conditioning and medical instrumentation front-ends. When designing with the LTC2415IGN, observe the 2.7 V to 5.5 V supply range and place 0.1 µF bypass capacitors near the VCC pin to minimise digital noise coupling. For best 50/60 Hz rejection, hold the FO pin high and ground the CS pin to enter 110 dB common-mode rejection mode; the digital interface timing should respect the 256 ms conversion period at the maximum output rate of approximately 15 samples per second. This page synthesises distributor pricing, drop-in pin-compatible alternatives, and practical design notes not found on the manufacturer datasheet alone, providing an actionable engineering reference for selecting and implementing the LTC2415IGN.
LTC2415IGN#TRPBF - 24-Bit µPower Delta-Sigma ADC | ADI
The Analog Devices LTC2415IGN#TRPBF is a 24-bit differential input, no-latency delta-sigma analog-to-digital converter housed in a 16-pin SSOP (GN) package. It operates from a 2.7V to 5.5V supply, achieves 2 ppm INL and 0.23 ppm RMS noise, and uses an integrated oscillator that eliminates the need for an external crystal or clock source. Single-cycle settling makes it ideal for multiplexed applications, while a single external pin can configure the LTC2415 for >110 dB input differential mode rejection at 50 Hz / 60 Hz. What is a delta-sigma ADC? A delta-sigma (ΔΣ) converter is a type of analog-to-digital converter that oversamples an input signal at a much higher rate than its Nyquist bandwidth and uses noise shaping to push quantization noise outside the signal band, then low-pass filters and decimates the result. The technique delivers very high resolution (16 to 32 bits) and excellent linearity at low frequencies, at the cost of conversion speed. Within the converter taxonomy, delta-sigma sits between successive-approximation register (SAR) ADCs (faster, lower resolution) and integrating ADCs (highest noise rejection at DC). The LTC2415 belongs to the no-latency ΔΣ family — every conversion produces a valid output without the pipeline delay found in many multi-bit ΔΣ parts. Key features include differential input and differential reference, on-chip oscillator, a 2.7 V – 5.5 V single supply, 24-bit output with 2 ppm INL, 0.23 ppm RMS noise (≈6 µV RMS at 5 V reference), and micropower operation. The common-mode voltage of both the input and the reference can be set independently anywhere between GND and VCC, easing bridge-, thermocouple-, and weigh-scale-style front ends. The architecture is a fourth-order delta-sigma modulator followed by a digital decimation filter; this topology is what gives the LTC2415 its single-cycle settling behavior and its exceptional normal-mode rejection at mains frequencies. Pin-for-pin and electrically compatible with the LTC2415-1 variant, this part is also a fit in 4-wire RTD and load-cell systems where the differential reference directly cancels ratiometric errors. Typical applications include precision weigh scales, strain-gauge bridges, thermocouple signal chains, 6-digit digital voltmeters, and battery-powered instrumentation. The wide common-mode range allows the ADC to digitize small differential signals riding on rails up to the full supply. When designing with the LTC2415IGN#TRPBF, note that its effective input range is bounded by the reference voltage — using a 5 V reference yields ±5 V differential input capability, while a 100 mV reference reduces it to ±100 mV. Place the reference and input bypass capacitors close to the pins and keep the digital SCK, SDO, and CS traces away from analog inputs to preserve the 0.23 ppm RMS noise floor. This page synthesizes distributor pricing, verified drop-in alternatives, and practical design notes that go beyond what is reproduced in the manufacturer datasheet, giving engineers one place to evaluate sourcing, parametric fit, and PCB-level design choices for the LTC2415 family.
LTC2451ITS8#TRMPBF - 16-Bit ΔΣ ADC, I2C, TSOT-23-8 | ADI
The Analog Devices LTC2451ITS8#TRMPBF is an ultra-tiny, 16-bit, delta-sigma analog-to-digital converter in an 8-pin TSOT-23 (3 mm × 2 mm) package, operating from a single 2.7 V to 5.5 V supply. It accepts a single-ended analog input, communicates through a standard I2C interface, and integrates an internal oscillator that requires no external timing components. The converter provides 16-bit output codes with a maximum output data rate of approximately 60 conversions per second. A delta-sigma ADC (also written ΔΣ ADC, sigma-delta ADC, or oversampling noise-shaping converter) is a type of analog-to-digital converter that uses high oversampling followed by digital decimation and noise shaping to achieve very high effective resolution at low bandwidths. The architecture trades input bandwidth for noise-free resolution, making ΔΣ ADCs the dominant choice for precision DC and low-frequency measurement in instrumentation, sensors, and battery monitoring. Within the data-converter hierarchy, the LTC2451 belongs to the precision-ADC family, which sits between high-speed successive-approximation (SAR) ADCs (>1 MSPS) and high-resolution integrating ADCs (>20 bits). Key features of the LTC2451 include integrated I2C addressing, a low quiescent supply current, an automatic shutdown between conversions that minimizes average power, and excellent DC accuracy (no missing codes at 16 bits). The TSOT-23-8 footprint occupies only 3 mm × 2 mm of PCB area, making the device one of the smallest precision ADCs available and an excellent fit for space-constrained sensor-interface applications. The device communicates via I2C with factory-programmable slave addresses selected by the I2C device address part suffix, enabling multiple LTC2451 devices on a single bus. Common-mode input range includes ground, allowing true zero-volt measurement in single-supply systems. The internal oscillator and digital filter settle a single conversion in approximately 16.6 ms without external components. Typical applications include portable instrumentation, weigh scales, direct temperature measurement with bridge sensors, gas and flow metering, isolated sensor front ends, battery monitors, and any precision microcontroller-based system that requires compact, low-power ADC functionality with a digital I2C bus. When designing with the LTC2451, place the decoupling capacitor as close as possible to the VDD pin and keep analog and digital ground returns short and joined at a single point to preserve noise-free 16-bit performance. The I2C lines should be pulled up to VDD with 2.2 kΩ to 10 kΩ resistors depending on bus speed and capacitance. This page synthesizes distributor pricing, verified drop-in alternatives, parametric comparisons, and practical design guidance that goes beyond a single datasheet reading, intended for engineers validating the LTC2451ITS8#TRMPBF for new designs or maintenance of existing single-supply precision-ADC subsystems.
LTC2461CDD - 16-Bit I2C Delta-Sigma ADC | Analog Devices
The Analog Devices LTC2461CDD is an ultra-tiny, 16-bit delta-sigma analog-to-digital converter with an integrated 1.25V precision reference, packaged in a 12-pin DFN (3x3 mm) and accessed via an I2C-compatible serial interface. It operates from a single 2.7V to 5.5V supply, delivers single-ended 0V-to-1.25V input range measurements, and achieves 10 ppm/°C maximum reference temperature drift while consuming only a few hundred microamps during active conversion. The device is offered in the commercial 0°C to +70°C temperature grade, distinguished by the "C" suffix in the part number, and ships lead-free (PBF) compliant with RoHS. What is a delta-sigma ADC? A delta-sigma (ΔΣ) analog-to-digital converter oversamples an input signal at a rate much higher than Nyquist and uses noise-shaping digital filtering to push quantization noise out of the signal band, achieving high resolution (16 bits and beyond) at the cost of conversion speed. Delta-sigma ADCs sit in the broader category of analog-to-digital converters > data converters > signal chain ICs > semiconductors, and are the standard choice for low-frequency, high-precision measurements. Key features of the LTC2461 include an integrated 1.25V reference with 10 ppm/°C drift, 16-bit no-missing-codes performance, single-cycle conversion, automatic sleep between conversions to minimize quiescent current, and a simple I2C interface with pin-selectable addresses. The internal oscillator eliminates the need for an external clock, and the small DFN-12 (3x3 mm) footprint makes it ideal for space-constrained sensor modules and battery-powered instruments where PCB area is at a premium. Technically, the LTC2461 uses a proprietary multi-order delta-sigma modulator followed by a digital SINC1 filter, providing single-cycle settling at the output data rate. The internal reference is factory-trimmed and temperature-compensated, removing the need for an external precision reference. The I2C interface supports standard (100 kHz) and fast (400 kHz) modes and includes a chip-enable pin that allows up to two devices on the same bus, simplifying multi-channel sensor designs. Typical applications include portable instrumentation, weight scales and force sensors, temperature and pressure monitoring, industrial process control front-ends, and battery-powered sensor nodes. The ultra-low power and tiny footprint make it especially attractive for IoT edge devices and wearable health monitors where every square millimeter and microamp matters. When designing with the LTC2461, observe the I2C pull-up resistor sizing rules and decouple VDD with a 0.1 µF ceramic capacitor placed as close as possible to the VDD pin. The input signal should be kept within 0V to VREF (1.25V); for higher voltage inputs, an external resistive divider or buffer is required. Use the chip-enable pin to share the I2C bus with another LTC2461 or LTC2463 device for dual-channel systems.

LTC2461IDD - 16-Bit I2C ADC, 12-DFN Package | Analog Devices
The Analog Devices LTC2461IDD is an ultra-tiny 16-bit delta-sigma analog-to-digital converter that combines a precision 1.25V integrated reference with an I2C serial interface in a 12-pin DFN (3 mm × 3 mm) package. It operates from a single 2.7 V to 5.5 V supply, accepts a single-ended 0 V to 1.25 V input, and delivers up to 16-bit resolution with no missing codes. The integrated reference exhibits 10 ppm/°C maximum drift and 0.1% initial precision, which lets the absolute displacement-error budget fit in 8-bit LSb at 25 °C. A delta-sigma ADC (also written delta-sigma or sigma-delta) is a type of oversampling converter that uses noise shaping to push quantization noise out of the baseband, enabling high effective resolution at low bandwidths without expensive laser-trimmed analog components. It belongs to the broader hierarchy of ADC (analog-to-digital converter) -> data converter -> mixed-signal IC -> semiconductor. The LTC2461's delta-sigma architecture paired with an integrated reference makes it well suited for compact, low-noise measurement front-ends where PCB real estate and BOM count are critical. Key features include 16-bit effective number of bits, 60 Hz output rate in 1x speed setting (up to 1.2 kHz in 2x), 1.25 V single-ended pseudo-differential input range, integrated 1.25 V reference with 2 ppm/°C typical drift, an I2C-compatible 2-wire serial interface with selectable addresses, internal oscillator, and automatic offset and full-scale calibration. The device continuously performs self-calibration, eliminating the need for external trimming while keeping total unadjusted error below a few LSb over temperature. The LTC2461IDD implements a proprietary charge-balancing modulator clocked by its own internal RC oscillator, so no external clock source is required. The output word rate is configurable via the I2C OBR (Output Rate) bit, and conversion results are available as standard 16-bit I2C read transactions. The 12-lead DFN package exposes the exposed pad for thermal and ground integrity. Typical uses include portable instrumentation, weigh scales, direct sensor digitisation for thermocouples and RTDs (with external front-end), battery-cell voltage monitoring in 3 V and 5 V systems, precision current sensing with a current-sense resistor, and consumer medical devices such as blood-pressure meters and glucose monitors. The integrated reference eliminates an extra IC in compact designs, and the I2C interface reduces microcontroller GPIO usage to two lines. When designing with the LTC2461IDD, place the 0.1 µF VDD bypass capacitor as close to the VDD pin as possible, and tie the GND exposed pad to a low-impedance ground pour to minimise digital return currents. For best noise performance, average multiple conversions in firmware and avoid switching the I2C SCL line near the ADC's acquisition window.

LTC2486IDE#TR - 16-Bit 4-Ch Delta-Sigma ADC w/ PGA | ADI
The Analog Devices (formerly Linear Technology) LTC2486IDE#TR is a 16-bit, 4-channel (2-channel differential) No Latency Delta-Sigma analog-to-digital converter with Easy Drive technology, integrated PGA, and I2C/SPI-compatible serial interface, housed in a 14-pin DFN (4x3 mm) package. The patented sampling scheme eliminates dynamic input current errors through automatic cancellation of differential input current, allowing large external source impedances and rail-to-rail input signals to be digitized directly. An ADC (analog-to-digital converter) is a data acquisition integrated circuit that converts continuous analog voltage signals into discrete digital codes for processing by microcontrollers, FPGAs, or DSPs. Delta-Sigma (ΔΣ) ADCs use oversampling and noise-shaping to achieve high resolution at the cost of conversion speed. Within the broader hierarchy, the LTC2486 sits as: ADC -> data converter -> data acquisition IC -> signal chain IC -> semiconductor. The "No Latency" feature guarantees that the first conversion after a new channel selection is valid, simplifying multiplexed measurements versus conventional delta-sigma ADCs that require settling cycles. Key features include 16-bit resolution with no missing codes, an integrated programmable gain amplifier, wide common-mode input range (0V to VCC) independent of the reference voltage, simultaneous 50Hz/60Hz rejection, and an external differential reference input. Easy Drive technology permits rail-to-rail inputs with source impedances up to several kilohms, eliminating the need for on-chip input buffers and their charge-kickback errors. The internal architecture combines a third-order delta-sigma modulator, a sinc4 digital filter, and an on-chip oscillator. The integrated PGA (gain 1 to 256) lets low-level sensor signals (such as thermocouples or strain gauges) be amplified before conversion. The serial interface (SPI) supports daisy-chain connection of multiple LTC2486 devices on a single bus. Reference voltage can be differential and ratiometric to the analog supply. Typical applications include direct thermocouple digitization with cold-junction compensation, bridge pressure transducers, weight scales, industrial temperature measurement, gas sensors, and battery cell monitoring. The wide common-mode range makes it ideal for any single-ended or differential sensor with ground-referenced signals. In multi-channel data-acquisition boards the LTC2486's per-channel valid-first-conversion behavior simplifies firmware because the controller does not have to discard dummy conversions after switching MUX channels. A key design consideration is choosing the reference voltage: lower reference (e.g., 100mV to 1V) combined with PGA gain maximizes dynamic range for low-level signals, while a higher reference (up to VCC) maximizes absolute accuracy. The DFN-14 package requires careful PCB layout with a low-impedance ground pour under the exposed pad (pin 14) for thermal dissipation and noise immunity. This page synthesizes distributor pricing, drop-in pin-compatible alternatives, and practical design notes not found in the manufacturer datasheet alone, helping engineers select, source, and implement the LTC2486IDE#TR with confidence.
LTC2493IDE - 24-Bit 4-Ch Delta-Sigma ADC with Easy Drive | ADI
The Analog Devices LTC2493IDE is a 24-bit, 4-channel (2-channel differential) No Latency Delta-Sigma analog-to-digital converter with patented Easy Drive technology and a 2-wire I2C interface, housed in a 14-pin DFN (4x3 mm) package. The ADC integrates an on-chip temperature sensor delivering 1/30th °C resolution and 2 °C absolute accuracy, and accepts any common-mode input from 0 V to VCC independent of the reference voltage, simplifying bridge and thermocouple front ends. A delta-sigma (ΔΣ) ADC is a type of oversampling converter that uses noise-shaping and digital filtering to achieve very high resolution at low sample rates. It belongs to the broader hierarchy of analog-to-digital converters → data converters → mixed-signal ICs → semiconductors, and is widely used in precision measurement where DC accuracy and noise rejection matter more than raw speed. The Easy Drive input current cancellation scheme of the LTC2493 eliminates dynamic input current errors that plague conventional delta-sigma ADCs, removing the need for on-chip input buffers and their associated offset/settling trade-offs. Key features include 24-bit no-latency operation, automatic offset and full-scale calibration every conversion cycle independent of input channel, 2-wire I2C interface, integrated temperature sensor, and an external fO clock pin that allows the user to override the internal conversion clock to change output rate and digital filter notch placement. The device operates from a single 2.7 V to 5.5 V supply with low supply current suited to battery-powered instrumentation. The architecture combines a multi-order delta-sigma modulator with a SINC4 digital filter, achieving excellent 50 Hz/60 Hz power-line rejection at default output rates and the ability to reject 50 Hz/60 Hz interference at custom rates by driving fO. The first conversion after a channel change is valid to full specification. Typical applications include precision weigh scales, strain-gauge bridges, thermocouple temperature measurement, industrial process control, and battery-powered portable instrumentation. The wide common-mode range and Easy Drive inputs make the LTC2493IDE particularly attractive for direct connection to resistive sensors and low-voltage bridges. Design consideration: drive the LTC2493IDE with a low-thermal-reference such as the LTC6655, and route the analog ground as a separate pour. Use a 0.1 µF ceramic bypass capacitor within a few millimeters of the supply pin to preserve noise performance.

LTC2662HUH-12#PBF - 5Ch 12-bit Current-Source DAC | Analog Devices
The Analog Devices LTC2662HUH-12#PBF is a 5-channel, 12-bit current-source digital-to-analog converter (DAC) that delivers five high-compliance current source outputs with a guaranteed 1 V dropout at 200 mA, housed in a 32-pin QFN (5x5 mm) package. Each output draws its current from a dedicated positive supply pin that accepts 2.85 V to 33 V, supporting load voltages up to 32 V and full-scale outputs up to 300 mA with eight per-channel programmable current ranges. Multiple channels can be paralleled for combined outputs up to 1.5 A, and internal 12 ohm switches allow any output pin to connect to an optional negative V- supply and sink up to 80 mA. A current-source DAC (also called a current-output DAC or IDAC) is a digital-to-analog converter whose output stage delivers a programmable current rather than a voltage. In the signal-chain taxonomy it sits below general-purpose DACs and above simple current mirrors: IDAC -> DAC -> data converter -> signal chain IC -> semiconductor. This category is the preferred building block when the load itself has a well-defined compliance voltage and the application requires precise, fast, and noise-immune current programming, such as LED biasing, laser diode drivers, and programmable current sources in test instruments. The LTC2662 integrates a precision reference, per-channel range registers, and a high-compliance output stage on a single die. The device operates over the -40 C to +125 C automotive/industrial temperature range and includes a serial peripheral interface (SPI) for digital configuration. The wide 32 V compliance and 200 mA continuous per-channel capability eliminate the need for external op-amp current boosters in many applications, while the parallelable architecture scales to multi-amp systems. The QFN-32 (5x5) package exposes a thermal pad that must be soldered to a ground copper pour for rated thermal performance. Typical applications include laser diode drive, LED biasing and dimming, programmable current sources, solenoid/actuator drive, and process-control instrumentation where bipolar or unipolar high-compliance currents are required. The 32 V compliance directly supports 28 V nominal industrial buses, while the 80 mA sink capability handles thermistor or Peltier biasing. When designing with this DAC, treat each output as an independent current source with its own V+ pin; use Kelvin-sense layout when load currents exceed 100 mA. Decouple every V+ pin with a 1 uF ceramic plus 10 uF bulk capacitor, and parallel outputs by tying OUT_x pins together before the load to achieve higher currents with matched range settings.

LTC2662HUH-16#PBF - 16-Bit 5-Ch 300mA Current-Source DAC | ADI
The Analog Devices LTC2662HUH-16#PBF is a 16-bit, five-channel current-source digital-to-analog converter (DAC) housed in a 32-pin QFN (5x5 mm) package, providing five high-compliance current source outputs with a guaranteed 1 V dropout at 200 mA and load voltage support up to 32 V. The LTC2662 family delivers 5 independently programmable channels of monotonic 16-bit (or 12-bit) current-output DAC with SoftSpan architecture that allows output ranges from 3 mA to 300 mA full-scale, all sharing the same 32-QFN footprint. What is a current-source DAC? A current-output digital-to-analog converter converts a digital code into a precise analog current, rather than voltage. Within the data-converter hierarchy, the LTC2662 belongs to the DAC family, more specifically current-steering or current-source DACs, which are widely used to drive laser diodes, precision actuators, programmable current bias, and process-control loops. Compared with voltage-output DACs, current-output parts eliminate output buffers and headroom-loss, allowing the load to sit at a high compliance voltage while the DAC itself drops just 1 V. Key features of the LTC2662HUH-16#PBF include guaranteed 1 V dropout at 200 mA per channel, 32 V load compliance, per-channel SoftSpan programmable full-scale current from 3 mA to 300 mA, a wide supply range (AVDD up to 5.5 V, load rail up to 32 V), and a flexible serial SPI-compatible interface with per-channel readback. The device uses a precision internal reference and offers daisy-chain capability for multi-device synchronization. The architecture is built around five matched current cells steered by a 16-bit segmented architecture. The internal reference and precision thin-film resistors deliver INL of approximately 1 LSB and DNL of ±0.5 LSB on the -16 grade. The wide compliance window (1 V to 32 V headroom over the load) lets the LTC2322662 directly drive H-bridges, optocouplers, and laser diodes without external driver stages. Typical applications include laser-diode driver bias for telecom and instrumentation, programmable current sources for industrial process control, optical attenuators, precision actuator drive in medical and test equipment, and 4 mA to 20 mA / 0 mA to 20 mA loop-driving when combined with an external boost stage. The 32-QFN footprint fits dense PCB designs and keeps channel-to-channel thermal coupling manageable. Design tip: decouple the AVDD pin with a 10 uF + 100 nF pair placed within 5 mm of the IC, and reserve a small copper island under the exposed pad to draw heat out of the package when more than two channels are operated near 200 mA. Ensure the load path returns to the LTC2662's GND to avoid ground-loop errors in the high-compliance current output.

MAX1002CAX+ - 60Msps Dual 6-Bit ADC, Low-Power | Maxim Integrated
The Maxim Integrated MAX1002CAX+ is a low-power, 60Msps, dual-channel, 6-bit analog-to-digital converter (ADC) housed in a 36-pin SSOP package. It combines high-speed, low-power operation with a user-selectable input range, an internal reference, and an internal clock oscillator. The dual, parallel ADCs are designed to convert in-phase (I) and quadrature (Q) analog signals into two 6-bit offset-binary-coded digital outputs at sampling rates up to 60Msps. An analog-to-digital converter (ADC) is a semiconductor component that transforms a continuous analog input signal into a discrete digital code. Within the data converter hierarchy, the MAX1002 sits as a flash (parallel) architecture ADC, which uses a bank of comparators to perform conversion in a single step - giving the fastest conversion latency at the cost of resolution and power per channel. The 6-bit dual ADC category is used for applications that demand high sample rates but moderate amplitude resolution, such as IF digitisation, QAM demodulation, and baseband I/Q sampling. Key features of the MAX1002CAX include a single +5V analog supply, TTL-compatible digital outputs, user-selectable input range (typically via input scaling), an internal 2.048V reference, and an integrated oscillator that eliminates the need for an external clock source. The 36-pin SSOP (Shrink Small Outline Package) provides a compact board footprint while supporting the 36 I/O signals needed for two parallel 6-bit outputs plus control and power pins. Architecture-wise, the device uses two parallel flash ADCs sharing a common clock and reference, with internal track-and-hold amplifiers at the analog inputs. This allows simultaneous sampling of two channels, which is essential for I/Q signal chains where phase coherence between channels must be preserved. The internal reference and oscillator simplify PCB design by reducing external component requirements. Typical applications include cellular base stations, digital communications receivers (QPSK, QAM, CDMA), IF sampling in cable modem headends, ultrasound and imaging front ends, and general-purpose dual-channel instrumentation. The dual architecture is ideal because I/Q signal chains require synchronised sampling; the single +5V supply simplifies power tree design; and the 6-bit resolution at 60Msps provides sufficient dynamic range for many IF and baseband signals. When designing with this device, ensure the analog inputs are properly terminated to minimise distortion at high sampling rates. Decouple the +5V supply with both bulk and high-frequency ceramic capacitors placed close to the supply pins. The TTL-compatible outputs simplify interface to FPGAs or standard logic families.
MAX1002CAX+T - 60Msps Dual 6-Bit ADC | Maxim Integrated
The Maxim Integrated MAX1002CAX+T is a low-power, 60Msps, dual-channel, 6-bit analog-to-digital converter (ADC) with TTL-compatible parallel digital outputs, housed in a 36-pin SSOP package and supplied on tape-and-reel. An ADC (analog-to-digital converter) is an integrated circuit that converts continuous analog signals into discrete digital codes for downstream DSP, FPGA, or microcontroller processing. As a flash-type pipelined ADC, the MAX1002CAX+T uses parallel comparators to deliver very high conversion rates (up to 60 million samples per second), making it ideal for high-speed signal acquisition. ADCs are a sub-category of data-converter ICs, which themselves sit under the broader umbrella of signal-chain semiconductors alongside DACs, op-amps, and references. Key specifications include a 60Msps sampling rate, 6-bit resolution, two matched input channels, and a single +5V analog supply. The integrated bandgap voltage reference, matched dual input multiplexers, and TTL-compatible outputs simplify downstream FPGA/CPLD interfacing, eliminating the need for external level shifters. Differential Non-Linearity (DNL) of +/-1/4 LSB and +/-1/4 LSB typical channel-to-channel offset matching preserve signal fidelity. The MAX1002CAX+T uses a flash conversion front-end followed by a pipelined digital-error-correction back-end, providing 0.1dB gain matching and 0.5-degree phase matching between the two channels. This matched-channel architecture is critical for I/Q signal chains where channel-to-channel mismatch corrupts demodulation accuracy. Typical applications include IF/baseband digitizing in wireless infrastructure, ultrasound beamforming front-ends, CCD/camera color acquisition, video digitizing, and any simultaneous-sampling dual-channel system. Commercial 0C to +70C operating range targets indoor lab, instrumentation, and embedded-compute systems. When designing with the MAX1002CAX+T, place a 0.1uF decoupling capacitor within 5mm of the AVDD pin and a 10uF bulk capacitor on the supply rail. Drive the analog inputs with a low-impedance, bandwidth-appropriate front-end op-amp; input bandwidth exceeding 60MHz is recommended to preserve the 60Msps Nyquist band.

MAX1009C/D-C10301 - 12-Bit 32-Channel ADC ASIC Die | Maxim Integrated
The Maxim Integrated MAX1009C/D-C10301 is a 12-bit, 32-channel analog-to-digital converter (ADC) supplied as a bare ASIC die (C/D) intended for custom hybrid assembly and multi-channel data-acquisition applications. Per distributor listings, it is described as an "IC ADC ASIC LN 32-CH DIE" and is offered in a Bulk packaging form factor suitable for die-mount and chip-on-board integration rather than standard surface-mount PCB assembly. The bare-die format allows the part to be integrated directly into multi-chip modules, sensor front-ends, and high-density instrumentation where a packaged 32-channel ADC would not fit. The product has a Maxim Integrated base part number prefix of MAX1009 and is sourced through authorized distributors as well as the open market. An ADC (analog-to-digital converter) is a data-converter integrated circuit that samples continuous analog input signals and quantizes them into discrete digital codes for downstream processing by microcontrollers, FPGAs, or DSPs. Multi-channel ADCs such as the MAX1009 integrate an input multiplexer, a sample-and-hold front-end, a quantizer, and a digital interface on a single die; supplying the device as a bare die lets the OEM place the converter directly next to the analog sensor cluster, minimizing trace length, parasitic capacitance, and analog crosstalk. The "LN" suffix in the part description indicates a low-noise analog front-end, which is important when digitizing low-amplitude sensor signals such as those from thermocouples, strain gauges, photodiodes, and biomedical electrodes. Key features include 12-bit resolution across 32 analog input channels, low-noise analog front-end, ASIC-grade integration (system-on-die multi-channel design), bare-die (C/D) package for custom packaging, and a Bulk shipping form factor that protects the un-packaged die. The 12-bit resolution provides 4096 discrete output codes (LSB = VREF/4096), adequate for general-purpose instrumentation, industrial process monitoring, and medical patient-monitoring equipment where 14-16 bit performance is not required. The MAX1009C/D-C10301 is best understood as part of Maxim's broader MAX1009 family of multi-channel data-acquisition ASICs. Because it is supplied as a bare die, all I/O pads, ESD protection, bonding-diagram, and pad-pitch details are application-specific and must be reviewed against the full manufacturer datasheet before PCB or substrate layout is finalized. Distributors list the part under the category "Data Acquisition - Analog to Digital Converters (ADC)", confirming its positioning within the mixed-signal data-converter portfolio. Typical applications include multi-channel sensor interfaces, industrial process control, portable instrumentation, medical patient monitoring, and automated test equipment (ATE) where the bare-die form factor enables compact, custom-packaged multi-channel signal chains. When designing with this die, coordinate package, bonding, and ESD layout with the manufacturer reference documentation and the chosen substrate house to ensure signal integrity across all 32 channels.
MAX1009C/D-C7H - 12-Bit ASIC ADC | Analog Devices | Industrial
The Analog Devices Inc./Maxim Integrated MAX1009C/D-C7H is a 12-bit analog-to-digital converter (ADC) implemented as an application-specific integrated circuit (ASIC) for embedded data-acquisition front-ends. The part features a high-impedance input stage and low-level input conditioning, and is specified for industrial measurement, medical systems, and general-purpose data-acquisition applications. It is offered as a bare die / wafer form (C/D suffix) and is sold through Maxim Integrated's authorized distribution channel as well as authorized aftermarket partners. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that samples a continuous-time analog voltage and converts it to a discrete digital code proportional to the input amplitude. Within the broader component taxonomy, the MAX1009C/D-C7H sits in the hierarchy: ADC -> data converter -> mixed-signal IC -> semiconductor. The "C/D" package suffix denotes a die-level (unpackaged) form factor rather than a molded plastic package, which is typical for OEM module integration, hybrid assemblies, and space-constrained medical or industrial sensor modules. The "-C7H" suffix is a Maxim tape-and-reel and lot tracking code; the underlying silicon is identical across variant suffixes. Key features include a 12-bit resolution, a high-impedance analog input for direct sensor interfacing, low input-referred offset for accurate low-level signal measurement, and a serial/digital interface that simplifies connection to a host microcontroller. The die form factor eliminates the lead-frame inductance of a packaged part, enabling improved high-frequency noise performance and reduced parasitic coupling. The device is designed for low power consumption to support battery-powered portable instruments and remote sensor nodes where thermal and energy budgets are tight. Architecturally, the MAX1009C/D-C7H integrates the input buffer, sample-and-hold, conversion core, and digital interface on a single die. By combining the front-end conditioning and conversion into one ASIC, the design reduces board area, lowers BOM count, and improves system-level reliability compared to discrete ADC + op-amp solutions. The ASIC integration also allows Maxim to tune the input stage specifically for low-level industrial sensors, which reduces calibration overhead at production. Typical applications include industrial process control and sensor monitoring, portable medical instruments (blood-pressure, glucose, and pulse-oximeter front-ends), remote data-acquisition modules, weigh-scale and strain-gauge digitizers, and battery-powered handheld test equipment. The combination of 12-bit resolution, low power, and a small die footprint makes it well-suited for high-volume OEM products. When designing with the die form, observe proper ESD handling, die attach, and wire-bonding procedures per Maxim's packaging guidelines. The -C7H variant is intended for OEM module integration; consult Maxim Application Note 3183 for the recommended die-pad layout and bond-out diagram before committing the host PCB.

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

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

AutoShutdown reduces supply current between conversions to microampere levels, suiting battery-powered data-acquisition applications. The MAX1030BCEG+TG002 uses a switched-capacitor input architecture with a high-impedance analog input multiplexer. The internal FIFO can buffer multiple conversion results, and internal averaging supports oversampling to improve effective resolution. The 24-QSOP package is footprint-compatible with the MAX1026 (12-channel) and MAX1028 (8-channel) family members, allowing channel-count scaling without PCB rework. Typical applications include industrial process control, multichannel data-acquisition systems, patient monitoring and portable medical instruments, battery-powered sensor systems with temperature compensation, system supervisory monitoring (using the on-chip temp sensor), and front-end digitizing for instrumentation. The +5 V analog supply and 5 V digital I/O make it a natural fit for legacy 5 V microcontrollers and embedded DSP systems. When designing with the MAX1030BCEG+TG002, observe the analog/digital supply sequencing guidelines in the manufacturer datasheet. Place the 0.1 µF and 10 µF decoupling capacitors as close as possible to the AVDD/DVDD pins, and keep analog inputs away from digital switching traces to preserve the 10-bit linearity and SNR performance.

It provides 8- or 16-channel single-ended or differential inputs, configurable through software, and supports an SPI/QSPI/MICROWIRE-compatible serial interface. A successive-approximation register ADC is a type of data converter that resolves one bit per internal clock cycle using a binary-search algorithm against a precision reference; it sits in the broader taxonomy of ADCs alongside sigma-delta, pipelined, and flash converters. The SAR architecture excels at low-latency, mid-speed multi-channel applications because each conversion completes in a deterministic number of cycles rather than integrating over many samples. The MAX1030's BiCMOS process integrates the analog input mux, sample-and-hold, reference, and digital FIFO on a single die. Key features include an integrated temperature sensor with ±1°C accuracy, an internal 4.096 V reference (or external reference option), a 16-entry FIFO that offloads host-processor traffic, and software-configurable unipolar/bipolar ±12 mA analog inputs. The internal analog input multiplexer allows scanning across 8 or 16 channels, making the part suitable for sensor-array applications. A dedicated reference output pin can drive external circuitry. Typical applications include system monitoring in networking and server hardware, multi-sensor data acquisition for industrial control, portable medical instrumentation with on-board temperature compensation, and front-end digitization for process-control loops. The integrated FIFO and temperature sensor simplify firmware by reducing host polling overhead. When designing with the MAX1030BETI+, ensure that the analog supply (AVDD) is well decoupled with a 10 µF tantalum plus 0.1 µF ceramic combination, and place the bypass capacitor as close as possible to the AVDD pin. Route the REF pin trace away from switching nodes to avoid reference noise coupling, and respect the 4.096 V absolute maximum reference voltage when interfacing to external sensor bridges.

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

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

MAX1036EKA+G002 - 8-Bit I2C ADC, 4-Ch, SOT-23-8 | Maxim
The Maxim MAX1036EKA+G002 is a 2.7 V to 5.5 V, low-power, 4-/12-channel, 2-wire serial 8-bit analog-to-digital converter (ADC) with an internal 4.096 V reference and 188 ksps conversion rate, housed in an 8-pin SOT-23 package. The +G002 variant is a special-order code extension; the base MAX1036 die is the same as the standard MAX1036EKA+ part. An ADC (Analog-to-Digital Converter) is a data-acquisition integrated circuit that samples continuous analog voltage signals and converts them into discrete digital codes for processing by microcontrollers, DSPs, or FPGAs. Successive-approximation-register (SAR) ADCs like the MAX1036 family use an internal capacitive DAC and comparator to perform one-bit-per-clock conversions, offering deterministic latency, low power, and excellent DC accuracy for multi-channel sensor monitoring and instrumentation. Key features of the MAX1036EKA+G002 include four single-ended or two differential analog input channels (selectable), an internal track/hold (T/H), a 4.096 V internal reference (also configurable for external reference), a 400 kHz Fast-Mode and 1.7 MHz High-Speed-Mode I2C-compatible serial interface, and an operating supply range of 2.7 V to 5.5 V. The internal reference and 4-channel MUX allow direct connection to sensors without external scaling. The MAX1036 uses a low-charge-injection input T/H that supports input bandwidths well beyond the Nyquist limit for accurate sampling of fast signals. With 188 ksps throughput and 8-bit resolution, the device offers low latency for loop control and panel-meter designs. The I2C/SMBus-compatible 2-wire serial bus reduces microcontroller I/O pin count and supports multi-device addressing. Typical applications include portable instrumentation, battery monitoring, panel meters, isolated sensor data acquisition, and 4-20 mA loop-powered transmitters. The wide supply range and integrated MUX make it well-suited for handheld multi-channel measurement. When designing with this device, place a 0.1 uF bypass capacitor on the supply pin and use a low-impedance reference bypass capacitor.

MAX1036EKA+G51 - 4/12-Ch 8-Bit I2C ADC, 5.5V | Maxim
The Maxim Integrated (Analog Devices) MAX1036EKA+G51 is a low-power, 4-/12-channel, 8-bit analog-to-digital converter (ADC) with an I2C-compatible 2-wire serial interface, offered in an 8-pin SOT23 package. According to the verified distributor listing, the part operates from a single 2.7V to 5.5V supply, integrates an internal track/hold, voltage reference, and clock, and supports 400 kHz Fast Mode and 1.7 MHz High-Speed Mode I2C operation. An 8-bit ADC (analog-to-digital converter) is a data-acquisition building block that quantizes an analog input voltage into 256 discrete digital codes, forming the lowest-resolution tier of the successive-approximation (SAR) ADC family. Within the broader signal-chain hierarchy - sensor -> signal conditioning -> ADC -> digital processing - 8-bit SAR ADCs are typically deployed where compact size, low power, and modest precision are required (e.g., system monitoring, threshold detection, simple instrumentation). The MAX1036/MAX1038 family specifically adds an internal 4.096V reference and 4 or 12 analog input channels, which positions the MAX1036EKA+G51 as a space-saving, low-pin-count alternative to discrete ADC + external reference solutions. Key features include a low supply current of approximately 350 uA at the maximum 225 ksps conversion rate, an internal 4.096V reference for the MAX1036 variant, software-configurable unipolar/bipolar input range, automatic channel scanning, and an I2C address that is hardware-selectable via an external resistor. The SOT23-8 package enables the part to fit next to sensors in tightly constrained PCB areas while still offering 12 single-ended or 6 differential input channels on the die (only AIN0-AIN3 are bonded out for the EKA/8-pin variant). The internal architecture uses a successive-approximation register (SAR) core, an integrated input track/hold, an on-chip 4.096V bandgap reference, and a state machine that supports both single-ended and differential conversions with software-selectable unipolar/bipolar input ranges. The +G51 suffix is a Maxim tape-and-reel packaging code, not an electrical variant, so the silicon matches the standard MAX1036EKA. Typical applications include portable/battery-powered sensor monitoring, system voltage and temperature supervision, panel-meter front-ends, and consumer-electronics housekeeping ADCs. The wide 2.7V-5.5V supply range allows the part to be powered directly from a single Li-ion cell, a 3.3V rail, or a 5V microcontroller supply without level shifters. When laying out a board, place the 0.1 uF supply bypass capacitor as close as possible to the VDD pin and keep analog input traces short and guarded to minimize digital coupling. The internal reference requires a minimum 0.1 uF external bypass capacitor on REF for low-noise operation.
