ADS8910BRGET

Analog To Digital Converters (ADC) Overview

The ADS8910BRGET is an 18-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single differential input and operates at a sampling rate of 1 MSPS with zero latency. The device integrates a low-dropout regulator (LDO) and a reference buffer, enabling single-supply operation. It accepts unipolar differential inputs within the range of ±VREF and supports VREF values from 2.5 V to 5 V. Power consumption is specified at 21 mW at full speed. The component utilizes an enhanced SPI digital interface with an SCLK capability of up to 20 MHz. It is housed in a 24-VQFN package measuring 4x4 mm and functions across a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high precision
• Medical instrumentation and diagnostic equipment
• Data acquisition systems for scientific instruments

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BRGET against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure that the supply voltage rails match the device requirements for both analog and digital domains. Confirm RoHS compliance status if environmental regulations apply to the target assembly. Cross-reference the ordering part number with authorized distributors to ensure authenticity and traceability.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 18-bit resolution and 1 MSPS throughput are required without external reference or regulator components. Compare power consumption metrics against lower-speed variants like the ADS8914B if system energy efficiency is critical. Verify that the differential input range aligns with the sensor output levels. Consider the thermal performance within the 24-VQFN package for the intended operating environment.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS891xB family of high-speed SAR ADCs from Texas Instruments. The family shares common architectural features such as integrated reference buffers and LDOs. Variants within the series differ primarily in sampling rates, including the 500-ksps ADS8912B and 250-ksps ADS8914B. All members utilize the same 24-VQFN footprint and multiSPI interface protocol.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8912BRGET and ADS8914BRGET are pin-compatible alternatives within the same family, offering lower sampling rates. These may serve as direct replacements if higher speed is not required. Verify that the reduced throughput meets the application's Nyquist criteria before substitution.
