TEXAS INSTRUMENTS ADS7949SRTER 模数转换器, 8 bit, 2 MSPS, 单, 2.7 V, 5.5 V, WQFN
DESCRIPON
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.
