Texas Instruments  ADS8910BRGER

The ADS8910B, ADS8912B, and ADS8914B (ADS891xB) belong to a family ofpin-to-pin compatible, high-speed, single-channel, high-precision, 18-bit successive approximationregister (SAR) analog-to-digital convertors (ADCs) with an integrated reference buffer andintegrated low-dropout regulator (LDO). The device family includes the ADS890xB (20-bit) andADS892xB (16-bit) resolution variants.

The ADS891xB boost analog performancewhile maintaining high-resolution data transfer by using TI’s enhanced-SPI feature. Enhanced-SPIenables the ADS89xxB to achieve high throughput at lower clock speeds, thereby simplifying theboard layout and lowering system cost. Enhanced-SPI also simplifies clocking-in of data, therebymaking this device an excellent choice for applications involving FPGAs, DSPs. The ADS89xxB iscompatible with a standard SPI Interface.

The ADS891xB has an internal data parityfeature that can be appended to the ADC data output. ADC data validation by the host, using paritybits, improves system reliability.
