ADC78H89CIMT - 7-Ch 500kSPS 12-Bit SAR ADC | Texas Instruments

The Texas Instruments ADC78H89CIMT is a low-power, 7-channel, 12-bit successive-approximation-register (SAR) analog-to-digital converter with a 500 KSPS throughput, housed in a 16-pin TSSOP package. Originally a National Semiconductor design now owned by Texas Instruments, the ADC78H89 accepts up to seven single-ended analog inputs on pins AIN1 through AIN7 and delivers straight-binary serial data through an SPI/QSPI/MICROWIRE-compatible interface. A SAR ADC is a type of data converter that performs a binary search across an internal capacitive DAC to resolve each analog sample in N clock cycles, where N is the resolution. The SAR architecture combines deterministic latency with inherent anti-alias filtering and is widely used in multiplexed data-acquisition systems, motor control loops, and instrumentation front-ends. SAR converters sit within the broader hierarchy of analog-to-digital converters (ADC -> data converter -> signal chain IC -> semiconductor) and trade the continuous-time linearity of delta-sigma ADCs for true single-shot sampling and low power dissipation. Key features of the ADC78H89CIMT include ±1 LSB maximum DNL and ±1 LSB maximum INL, an operating temperature range of -40 °C to +85 °C, and very low power consumption: typically 1.5 mW at 3 V supply and 8.3 mW at 5 V supply. The 16-pin TSSOP footprint offers a small board area suitable for portable or space-constrained designs, while the internal track-and-hold and serial interface minimize external component count. The device operates from a 2.7 V to 5.25 V analog supply, supporting both 3 V and 5 V system rails. The SAR core, internal reference option, and seven-channel input multiplexer make the part a single-chip solution for sensor-array digitizing where deterministic latency and low power are more important than raw conversion speed. Designers can run the part from an external clock or the internal oscillator depending on system timing constraints. Typical applications include automotive navigation and infotainment subsystems, portable battery-powered instruments, medical instrumentation such as patient-monitoring front-ends, mobile-communication baseband signal-conditioning, and general-purpose industrial instrumentation and control systems. Its low power also suits remote, solar-powered sensor nodes. A key design consideration is that the /CS, SCLK, DOUT, and DIN pins form the four-wire serial interface, and the AIN0-AIN6 pins share a common ground reference. Decouple AVDD with a 10 µF and 0.1 µF pair placed within 5 mm of the supply pin, and keep digital return currents isolated from the analog ground return to preserve the device's specified DNL/INL. This page consolidates distributor pricing, drop-in TSSOP-16 alternatives, and practical design guidance that are not available in the manufacturer's datasheet alone.

The Texas Instruments ADC78H89CIMTX is a low-power, 7-channel, 12-bit successive-approximation-register (SAR) analog-to-digital converter with a maximum throughput of 500 kSPS, packaged in a 16-pin TSSOP. The converter accepts up to seven single-ended input signals on pins AIN1 through AIN7 and produces straight-binary serial output data over an SPI-compatible interface. An ADC (analog-to-digital converter) is a data-acquisition integrated circuit that converts continuous analog signals into discrete digital codes; SAR ADCs use a binary-search capacitor network to resolve each conversion in N clock cycles, making them well-suited for multiplexed multi-channel systems where low latency and deterministic behavior are required. The ADC78H89 sits in the broader hierarchy of SAR ADC -> data converter -> data acquisition IC -> signal chain IC -> semiconductor. Multi-channel SAR ADCs like this one are commonly used to digitize several sensor or control signals through a single serial port, reducing MCU pin count and BOM cost. Key specifications include 12-bit resolution, a 500 kSPS conversion rate, seven analog input channels, an internal track-and-hold circuit, single-supply operation from 2.7 V to 5.25 V, and a straight-binary serial data output. The architecture supports pseudo-differential or single-ended inputs and includes a hardware shutdown pin to reduce current consumption between conversions, which is important for battery-powered and thermally-constrained designs. The SAR core is paired with an on-chip input multiplexer, sample-and-hold amplifier, and an SPI/QSPI/MICROWIRE-compatible serial I/O block. The internal reference and clock options reduce external component count, while the TSSOP-16 footprint allows the part to be placed in compact multiplexed sensor front ends. Typical SNR and INL behavior of this family is suitable for general-purpose 12-bit precision instrumentation rather than audio or 16+ bit precision. Typical applications include multi-sensor data acquisition in industrial control, battery monitoring in portable instrumentation, HVAC and appliance sensor aggregation, microcontroller-based measurement nodes, and general-purpose multi-channel instrumentation. Designers select this ADC when 12-bit accuracy, seven channels, and SPI connectivity are sufficient and lowest-cost general-purpose conversion is desired. When designing with the ADC78H89CIMTX, ensure that the analog supply is well decoupled (typically a 10 µF bulk plus 0.1 µF ceramic close to AVDD), that the SCLK frequency respects the 500 kSPS timing budget across all seven channels, and that the CS/SHUTDOWN logic is sequenced correctly to enter low-power shutdown between conversions.

The Texas Instruments ADC78H90CIMT is an 8-channel, 12-bit, 500 kSPS successive-approximation register (SAR) analog-to-digital converter housed in a 16-pin TSSOP (PW) package. The part accepts up to eight single-ended input signals at AIN1 through AIN8 and outputs straight binary serial data compatible with standard SPI/QSPI/MICROWIRE interfaces, supporting -40C to +85C operation. An SAR ADC is a precision data converter that uses a binary search algorithm and an internal track-and-hold to digitize analog signals at the moment of sampling; SAR ADCs are prized for low latency, deterministic throughput, and excellent dc accuracy, sitting hierarchically under analog-to-digital converter -> data converter -> mixed-signal IC -> semiconductor. The ADC78H90 family is intended for multi-channel, low-power monitoring tasks where deterministic sampling and a small footprint matter more than the highest possible sample rate. Key specifications of the ADC78H90 include 12 bits of resolution, 500 kSPS maximum throughput, eight analog input channels selected by internal addressing, and a CMOS successive-approximation architecture with an internal track-and-hold circuit. The serial output data is straight binary, which simplifies host firmware and avoids the overhead of two's-complement decoding in microcontrollers and DSPs. Architecturally, the device combines a low-power CMOS SAR core, an 8-channel analog multiplexer, an internal reference/sample-and-hold, and a simple synchronous serial interface (SCLK, DOUT, CS). The deterministic per-conversion latency makes the part well-suited to multiplexed multi-channel scanning without the phase-skew issues that plague some delta-sigma ADCs in control loops. Typical applications include sensor and transducer monitoring in industrial control, process automation analog front ends, portable battery-powered instrumentation, multi-channel data-acquisition modules, and consumer audio or appliance front panels where up to eight analog signals must be read from a small PCB. Design tip: this part is supplied under the IMT tape-and-reel designation (TSSOP-16 PW); the rail variant carries /NOPB marking per Texas Instruments product naming. Ensure the SPI host supports the chosen SCLK frequency at 500 kSPS and that digital and analog grounds are tied at a single star point to preserve 12-bit accuracy.

ADCS7476AIMF/NOPB

ADCS7476AIMF/NOPB - 1MSPS 12-Bit SAR ADC, SOT-23-6 | Texas Instruments

The Texas Instruments ADCS7476AIMF/NOPB is a 12-bit, 1 MSPS, low-power, monolithic CMOS successive-approximation-register (SAR) analog-to-digital converter housed in a 6-pin SOT-23 package with a 2.7V to 5.25V analog supply range. Per the manufacturer datasheet, the device accepts a single-ended analog input and provides the conversion result through an SPI-/QSPI-/MICROWIRE-/DSP-compatible serial interface, making it one of the smallest full-spec 1 MSPS 12-bit ADCs available in a SOT-23 footprint. An SAR ADC (Successive Approximation Register Analog-to-Digital Converter) is a type of data converter that uses a binary-search algorithm against an internal precision DAC to determine each code bit in N clock cycles. SAR ADCs are valued for their deterministic latency, lack of pipeline delay, and excellent DC accuracy, sitting hierarchically below pipelined ADCs (used) and delta-sigma ADCs (used) and above simple flash ADCs in the data-converter taxonomy. Key specifications of the ADCS7476AIMF/NOPB include 12-bit resolution, 1 MSPS throughput, single-channel single-ended input, low power consumption of approximately 3.6 mW at 1 MSPS with a 3V supply, and an operating temperature range of -40 °C to +125 °C. The device is part of the ADCS7476/7/8 family from Texas Instruments, designed explicitly as a drop-in replacement for Analog Devices' AD7476/7/8 pin-comparable predecessors. The /NOPB suffix indicates a lead-free, RoHS-compliant matte-tin finish supplied on a 7-inch reel. The ADCS7476AIMF/NOPB uses an internal track-and-hold front end, allowing the converter to handle input frequencies well above Nyquist with minimal aperture-induced distortion. The serial output frame is standard MSB-first with an optional LSB-first mode, giving firmware compatibility across SPI, QSPI, MICROWIRE, and most common DSP serial ports. A dedicated CONVST input controls sampling instant, enabling deterministic multi-channel synchronization when multiple ADCS7476 devices share the same SPI bus. Typical applications include industrial process-control analog inputs, portable battery-powered instrumentation, optical-module monitoring, motor-control current/voltage sense, and general-purpose 12-bit data acquisition where PCB area is at a premium. Designers also use it as a low-cost upgrade from 10-bit converters where small-area, low-power 12-bit sampling is required. When designing with this part, place the 0.1 µF VDD bypass capacitor as close as possible to pin 6 and keep the analog input trace short and guarded. Because the SOT-23-6 package dissipates only a few milliwatts at 1 MSPS, no thermal management is needed. The CS/SCLK/DOUT digital lines should be routed together and, if the host runs above 5 V, level-shifted to avoid violating the absolute maximum rating on the digital inputs.

ADCS7477AIMF - 10-Bit 1MSPS SAR ADC, SOT-23-6 | Texas Instruments

The Texas Instruments ADCS7477AIMF is a 10-bit, 1 MSPS successive-approximation-register (SAR) analog-to-digital converter housed in a 6-pin SOT-23-6 package. It operates from a 2.35 V to 5.25 V analog and digital supply and consumes only a few milliwatts at full sampling rate, targeting size-constrained portable and industrial designs. The converter uses a low-power CMOS architecture with internal track-and-hold and exposes a serial interface compatible with SPI, QSPI, MICROWIRE, and most DSP serial ports. A SAR ADC (Successive Approximation Register Analog-to-Digital Converter) is a type of data converter that uses a binary-search algorithm against an internal DAC to determine each code, requiring only N conversion cycles for an N-bit sample. SAR ADCs sit between slower integrating converters and high-speed pipelined flash ADCs in the data-converter hierarchy: data converter -> ADC -> successive approximation ADC -> medium-speed monolithic ADC -> power management / signal-chain IC. SAR architectures are prized for deterministic latency, low power, and excellent DC accuracy, which is why they dominate industrial control, instrumentation, and battery-powered sensor applications. Key features of the ADCS7477AIMF include 1 MSPS throughput, 10-bit resolution with no missing codes, an internal 2.5 V reference option (ADCS7478 / ADCS7476 variants adjust resolution), a true-differential analog input stage, and a hardware-friendly shutdown pin that drops supply current to microamp levels for power-cycled applications. The 6-pin SOT-23 footprint makes the device the smallest member of TI/NSC's ADCS747x monolithic ADC family. Typical applications include portable instrumentation, optical module monitoring, high-speed data acquisition front-ends, motor-control feedback sampling, and precision sensor signal chains where compact PCB area and deterministic latency are required. The combination of low power consumption, small footprint, and industry-standard SPI-compatible interface makes this part attractive for designers migrating from legacy parallel ADCs that consumed far more board area. A primary design trade-off is the choice of internal-versus-external voltage reference: the internal reference minimizes external BOM but constrains absolute accuracy, whereas an external reference improves gain error and temperature drift at the cost of an extra component and pin. Adding a 0.1 µF ceramic decoupling capacitor within 5 mm of the AVDD pin and a small RC anti-alias filter at AIN is recommended. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes beyond what is found on DigiKey, Mouser, or TI's product page, giving engineers a single canonical reference for the ADCS7477AIMF.

The Texas Instruments ADCS7478AIMF is a low-power, monolithic CMOS 8-bit analog-to-digital converter that operates at 1 MSPS in a 6-pin SOT-23 package. It uses a successive approximation register (SAR) architecture with an internal track-and-hold, single 2.7V to 5.25V supply operation, and a serial interface compatible with SPI, QSPI, and MICROWIRE standards. The ADCS7478AIMF is part of the ADCS747x drop-in replacement family for the legacy Analog Devices AD7476/77/78 series. An analog-to-digital converter (ADC) is a data conversion device that converts a continuous analog voltage into a discrete digital code. Within the broader data converter hierarchy, an ADC sits inside signal chain ICs -> data converters -> ADCs. SAR ADCs sample the input once per conversion, then perform a binary search through an internal DAC to resolve the bits, offering deterministic latency and excellent DC accuracy with very low power consumption at moderate sample rates. The ADCS7478AIMF targets cost- and size-sensitive embedded designs needing 8 bits of resolution at up to 1 MSPS. Key features include 1 MSPS throughput, an SPI/QSPI/MICROWIRE-compatible serial interface, an on-chip clock, single 2.7V to 5.25V supply with the supply used as the reference, and an analog input range from 0V to VDD. The part draws only a few mW during active conversion and supports power-down modes for battery-powered or duty-cycled applications. The SOT-23-6 footprint measures roughly 2.9mm x 1.6mm, making the converter one of the smallest 1 MSPS SAR ADCs available. The ADCS7478AIMF is built on a CMOS process with an internal track-and-hold front end and a charge redistribution SAR core. It uses VDD as its reference voltage, eliminating the need for an external reference. The serial data output is straight binary, and the conversion rate is fixed at the internal oscillator. According to TI's datasheet, the device can also be used with an external reference by injecting a reference voltage through the VDD pin when configured appropriately. Typical applications include portable data loggers, isolated voltage and current sensing in industrial controls, optical module monitoring, system monitoring and housekeeping on microcontroller cards, and battery management in portable medical devices. The combination of small package, low power, and standard SPI interface lets the ADCS7478AIMF sit directly behind a sensor or shunt, sending readings back to a microcontroller with minimal firmware overhead. When designing with the ADCS7478AIMF, ensure the SPI clock is provided only during conversion and acquisition. Decouple VDD with a 100nF ceramic capacitor placed as close to pin 6 as possible, and keep the analog input trace short and guarded to ground. Verify that the microcontroller SPI mode matches the ADC's clock polarity and phase (CPOL=0, CPHA=0 by default).

ADCS7478AIMFX - 8-Bit 1MSPS SAR ADC, SOT-23-6 | Texas Instruments

The Texas Instruments ADCS7478AIMFX is an 8-bit, 1 MSPS successive-approximation-register (SAR) analog-to-digital converter in a 6-pin SOT-23 package with a single-ended analog input, SPI/MICROWIRE/QSPI-compatible serial interface, and single 2.7 V to 5.25 V supply operation using the supply as the reference. The part is specified over the -40 °C to +85 °C industrial temperature range and ships on 3000-piece tape-and-reel. A SAR ADC is a successive-approximation analog-to-digital converter: it performs a binary search through an internal capacitive DAC to converge on the input voltage in N conversion cycles, where N is the resolution in bits. Compared with delta-sigma or pipeline ADCs, SAR converters offer deterministic latency, no pipeline delay, and excellent dynamic performance at moderate sample rates, which makes them the workhorse for multiplexed data acquisition, motor control, and instrumentation front-ends. The ADCS7478 uses the supply pin itself as the conversion reference, eliminating an external reference and supporting the smallest possible footprint for cost- and space-constrained designs. The serial interface is compatible with SPI, QSPI, and MICROWIRE hosts, allowing direct connection to most microcontrollers and DSPs without glue logic. The device also offers a power-down pin to minimize supply current between conversions. Architecturally, the ADCS747x family is a CMOS SAR core with internal track-and-hold, scaled to deliver 1 MSPS throughput at low power dissipation. The ADCS7478 is the 8-bit resolution member of the family; the ADCS7476 (12-bit) and ADCS7477 (10-bit) share the same SOT-23-6 pinout, allowing designers to migrate resolution without changing PCB layout. Typical applications include portable instrumentation, isolated data acquisition, optical modules, and consumer electronics where a small-footprint ADC with digital-friendly serial output is needed. Battery-powered sensor readouts benefit from the integrated power-down mode between samples. When designing with the ADCS7478, add 0.1 µF decoupling close to the supply pin and keep the analog input trace short to minimize coupling from the serial clock. Note that using VDD as the reference couples digital noise into conversions; for higher-precision requirements, use an external ADC with a dedicated reference.

ADCV08832CIM/NOPB - 8-Bit 38kSPS SAR ADC, Serial I/O | TI

The Texas Instruments ADCV08832CIM/NOPB is a low-voltage, 8-bit successive approximation register (SAR) analog-to-digital converter with a 3-wire MICROWIRE-compatible serial interface, integrated sample-and-hold, and up to 38 kSPS sampling rate, housed in an 8-pin SOIC (0.154 inch / 3.90 mm width) package. An SAR ADC is a type of data converter that uses a binary-weighted capacitive DAC and a comparator to perform a bit-by-bit search against the input voltage, settling one conversion result per N clock cycles for N bits of resolution. SAR ADCs sit within the broader hierarchy of analog-to-digital converter -> data converter -> mixed-signal IC -> semiconductor, and are favored for low-power, latency-deterministic acquisition of single-ended signals in embedded systems. Key features include 8-bit resolution, single +2.7V to +5.5V analog and digital supply operation (low-voltage CMOS), a 3-wire MICROWIRE/QSPI/MICROWIRE-PLUS compatible serial data interface (CS, SCLK, DOUT), an internal sample-and-hold, and an automotive operating temperature grade of -40C to +125C. The ADCV08832 uses a charge-redistribution SAR architecture with an input sample-and-hold that captures the input on the rising edge of CS, then performs eight internal clock cycles of bit-trial conversion. The serial engine shifts out the MSB-first conversion result on DOUT, clocked by SCLK, with CS framing each conversion. The architecture is fully self-clocked from SCLK after the input acquisition phase, so no external high-frequency master clock is needed for the conversion core. Typical applications include portable instrumentation front-ends, automotive sensor signal acquisition (thermistor, RTD, potentiometer, throttle position), loop-powered 4-20 mA transmitter readback, low-cost microcontroller analog input expansion, and embedded data logging where 8-bit resolution is acceptable. When designing with this part, place a 0.1 uF decoupling capacitor as close as possible to the VDD pin and keep the analog input trace short and guarded to preserve the SAR's ~38 kSPS settling behavior. The reference voltage (VREF) must be stable and decoupled - reference noise couples directly into the conversion LSBs.

ADE7751ARSZRL

ADE7751ARSZRL Single-Phase Energy Meter IC | Analog Devices

The Analog Devices ADE7751ARSZRL is a single-phase, fault-tolerant electrical energy measurement IC supplied in a 24-SSOP package. According to the manufacturer product page, it is intended for two-wire distribution systems and provides instantaneous and average real-power measurements derived from line-voltage and current inputs. The verified distributor listing identifies the device as an energy-metering IC in a 24-SSOP package. The manufacturer also states that the ADE7751 is pin compatible with the AD7751 and has the same functionality, with synchronized low-frequency and high-frequency outputs under all load conditions. These features place the ADE7751 within the energy-metering IC category, where analog signal conditioning, digital conversion, power calculation, calibration, and fault detection are integrated into one device. The supplied data does not provide a complete electrical parameter table, so values such as exact current-input range, accuracy grades, conversion rates, temperature limits, and calibration details are marked for verification in the specifications. An electrical energy measurement IC is a specialized mixed-signal semiconductor that converts voltage and current waveforms into digital information used for watt-hour accumulation, load monitoring, and utility metering. In the broader device hierarchy, an energy-metering IC belongs to analog and mixed-signal ICs, then to power-monitoring and measurement systems, and ultimately to power-management electronics. It is designed to reduce the number of separate components needed between analog sensing inputs and a metering processor. The ADE7751 is particularly relevant to single-phase, two-wire distribution systems where accurate real-power information and fault tolerance are required. The verified manufacturer information identifies these key engineering features: instantaneous real-power output, average real-power output, external gain calibration between channels, synchronized low-frequency and high-frequency outputs, and fault-tolerant operation. The synchronization feature is significant in metering designs because it helps coordinate output signals across changing load conditions. The manufacturer comparison also establishes compatibility with the AD7751, which is a useful starting point for legacy or redesign evaluations. The exact output logic, register map, filter behavior, and calibration method should be confirmed in the Analog Devices datasheet before schematic sign-off. The ADE7751ARSZRL is suitable for utility-grade single-phase metering, energy-monitoring modules, load-control equipment, industrial power instrumentation, and embedded measurement systems. In a practical circuit, the voltage and current channels are connected to external sensing networks, while the device performs measurement and exposes digital information to a host processor or display path. Designers should pay attention to input filtering, grounding, calibration components, fault-detection thresholds, and the distinction between average power and instantaneous power. The supplied data confirms the package and application category but does not confirm exact timing, accuracy, or environmental limits. The principal design consideration is verifying the complete Analog Devices datasheet and device-specific ordering information before layout or firmware decisions are finalized. The verified distributor result lists the part as tape-and-reel packaged, but it does not provide the reel quantity. The product should therefore be treated as an engineering component whose electrical limits, calibration requirements, and environmental ratings remain subject to datasheet verification. This page combines manufacturer identity, distributor package information, replacement research, and practical selection guidance rather than inventing unverified performance values. This data record provides a concise component overview, verified source links, package classification, and engineering-oriented replacement context for ADE7751ARSZRL. The alternatives array is intentionally limited to same-brand parts explicitly supported by the supplied Analog Devices cross-reference material; unsupported cross-brand claims are not presented as drop-in replacements.
