ADS7038 - Texas Instruments

ADS7038 12-Bit ADC

The ADS7038 is an easy-to-use, 8-channel, multiplexed, 12-bit, 1-MSPS, successive approximation register analog-to-digital converter (SAR ADC). The eight channels can be independently configured as either analog inputs, digital inputs, or digital outputs. The device has an internal oscillator for the ADC conversion process. The ADS7038 communicates via an SP.
