The ADS7947, ADS7948, and ADS7949 are pincompatible 12-bit, 10-bit, and 8-bit, 2-MSPS, analogto-digital converters (ADCs), respectively. The devices operate at a 2-MSPS sample rate with a standard 16 clock data frame. In addition, the ADS7947 (12-bit) can be operated at 2.1 MSPS, the ADS7948 (10-bit) at 2.57 MSPS, and the ADS7949 (8-bit) at 3 MSPS with a sho.
