ADS8910BRGER

Analog To Digital Converters (ADC) Overview

The ADS8910BRGER is an 18-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single differential input channel and supports a maximum sampling rate of 1 MSPS with zero latency output. The device operates on dual power supplies, accepting analog voltages between 3 V and 5.5 V and digital logic levels from 1.65 V to 5.5 V. It utilizes an enhanced SPI interface capable of clock speeds up to 20 MHz. Packaged in a 24-pin VQFN format measuring 4x4 mm, it functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated low-power reference buffer eliminates external droop concerns
• Enhanced SPI interface supports high-speed data transfer at 20 MHz
• Single-supply operation enabled by integrated LDO regulator
• High linearity performance with no missing codes across the full scale

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution signal acquisition
• Medical instrumentation such as ultrasound and patient monitoring devices
• Precision data acquisition modules for test and measurement equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'GER' against the manufacturer datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 24-VQFN component. Confirm that the supply voltage rails match the required 3V-5.5V analog and 1.65V-5.5V digital ranges before integration into the design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 18-bit resolution and 1 MSPS throughput are required without pipeline latency. Compare against the ADS8912B or ADS8914B if lower sampling rates allow for reduced power consumption. Verify that the external reference voltage falls within the 2.5 V to 5 V range to ensure optimal dynamic performance and input swing capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS891xB family of high-speed SAR ADCs. It shares architectural similarities with the ADS890xB series but offers different resolution and speed trade-offs. The BRG suffix indicates a specific thermal and packaging variant designed for surface-mount assembly in compact electronic designs.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8910BRGET serves as a direct pin-compatible alternative within the same package. For applications requiring higher resolution, consider the ADS8900 series. Lower speed variants like the ADS8912B may offer power savings if the 1 MSPS rate exceeds system requirements.
