8.1 Overview

The ADS7947 is 12-bit, miniature, dual-channel, low-power successive-approximation register (SAR) analog-to-digital converter (ADC). The ADS7948 and ADS7949 are 10-bit and 8-bit devices, respectively, from the same product family. These devices feature low-power consumption at full-speed. The PDEN pin enables an auto power-down mode that further reduces power consumption at lower speeds.
