Overview: Product Folder Order Now Technical Documents Tools & Software Support & Community ADS8910B ADS8912B ADS8914B SBAS707B – JUNE 2016 – REVISED JANUARY 2018 ADS891xB 18-Bit, High-Speed SAR ADCs With Integrated Reference.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The ADS8910B, ADS8912B, and ADS8914B (ADS891xB) belong to a family of pin-to-pin compatible, high-speed, single-channel, highprecision, 18-bit successive approximation register (SAR) analog-to-digital convertors (ADCs) with an integrated reference buffer and integrated lowdropout regulator (LDO).

The device family includes the ADS890xB (20-bit) and ADS892xB (16-bit) resolution variants.

The ADS891xB boost analog performance while maintaining high-resolution data transfer by using TI’s enhanced-SPI
