The ADS8910B, ADS8912B, and ADS8914B (ADS891xB) belong to a family of
pin-to-pin compatible, high-speed, single-channel, high-precision, 18-bit successive approximation
register (SAR) analog-to-digital convertors (ADCs) with an integrated reference buffer and
integrated low-dropout 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 feature. Enhanced-SPI
enables the ADS89xxB to achieve high throughput at lower clock speeds, thereby simplifying the
board layout and lowering system cost. Enhanced-SPI also simplifies clocking-in of data, thereby
making this device an excellent choice for applications involving FPGAs, DSPs. The ADS89xxB is
compatible with a standard SPI Interface.
The ADS891xB has an internal data parity
feature that can be appended to the ADC data output. ADC data validation by the host, using parity
bits, improves system reliability.
