ADS891xB 18-Bit, 1 MSPS, SAR ADCs

Texas Instruments offers its ADS891xB 18-bit, 1 MSPS, SAR ADCs with internal reference buffer, internal LDO, and multiSPI™ interface

Image of Texas Instruments' ADS891xB 18-Bit, 1-MSPS, SAR ADCsTexas Instruments' ADS8910B, ADS8912B, and ADS8914B (ADS891xB) belong to a family of pin-to-pin compatible, high-speed, high-precision successive approximation register (SAR) based analog-to-digital convertors (ADCs) with an integrated reference buffer and integrated low-dropout regulator (LDO). These devices support unipolar, fully differential, analog input signals with ±0.5 LSB INL and 102.5 dB SNR specifications under typical operating conditions.

The integrated LDO enables single-supply operation with low power consumption. The integrated reference buffer supports burst-mode data acquisition with 18-bit precision for the first sample. External reference voltages in the range 2.5 V to 5 V 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).

The ADS891xB family is offered in a space-saving, 4 mm x 4 mm, VQFN package, and is specified over the extended temperature range of -40°C to 125°C.
