Product Description

DESCRIPTION
The ADS7947/8/9 are 12-bit, 10-bit, and 8-bit 2MSPS analog-to-digital converters (ADCs), respectively. Devices operate at 2MSPS sample rate with a standard 16 clock data frame. In addition, it is possible to operate the ADS7947 (12-bit) at 2.1MSPS, the ADS7948 (10-bit) at 2.57MSPS, and the ADS7949 (8-bit) at 3MSPS with a short data frame optimized for the number of clocks sufficient for conversion with no drop in performance. The devices feature both outstanding dc precision and excellent dynamic performance, this family of pin-compatible devices includes a two-channel input multiplexer and a low-power successive approximation register (SAR) ADC with an inherent sample-and-hold (S/H) input stage.
