Texas Instruments ADS8904BRGER

The ADS8900B, ADS8902B, and ADS8904B (ADS890xB) belong to a family of pin-to-pin compatible, high-speed, single-channel, high-precision, 20-bit successive-approximation-register (SAR) analog-to-digital converters (ADCs) with an integrated reference buffer and integrated low-dropout regulator (LDO). The device family includes the ADS891xB (18-bit) and ADS892xB (16-bit) resolution variants.

The ADS89xxB boosts analog performance while maintaining high-resolution data transfer by using TI’s Enhanced-SPI feature. Enhanced-SPI enables ADS89xxB in achieving high throughput at lower clock speeds, there by simplifying the board layout and lowering system cost. Enhanced-SPI also simplifies the host’s clocking-in of data there by making it ideal for applications involving FPGAs, DSPs. ADS89xxB is compatible with standard SPI Interface.

The ADS89xxB has an internal data parity feature which can be appended to the ADC data output. ADC data validation by the host, using parity bits, improves system reliability.
