ADS892xB 16-Bit SAR ADCs

Texas Instruments ADS892xB 16-Bit SAR Analogue-to-Digital Converters (ADCs) are a family of pin-to-pin-compatible, high-speed, high-precision successive-approximation-register (SAR)-based ADCs. Each of these has an integrated reference buffer and integrated low-dropout regulator (LDO). These devices support unipolar, fully differential, analogue input signals with ±0.5LSB INL and 96dB SNR specifications for the specified temperature range. The integrated LDO enables single-supply operation with low power consumption. The integrated reference buffer supports burst-mode data acquisition with 16-bit precision for the first sample. External reference voltages in the range 2.5V to 5V are supported, offering a wide selection of input ranges without additional input scaling. The integrated multiSPI digital interface is backward-compatible to the traditional SPI protocol. Additionally, configurable features simplify board layout, timing, and firmware, and support high throughput at lower clock speeds. The multiSPI digital interface allows for easy interface with a variety of microcontrollers, digital signal processors (DSPs), and field-programmable gate arrays (FPGAs).
