ADS7040 Description
The ADS7040 is a 8-bit, 1-MSPS, analog-to-digital converter (ADC). The device supports a wide analog input voltage range (1.65 V to 3.6 V) and includes a capacitor-based, successive-approximation register (SAR) ADC with an inherent sample-and-hold circuit. The SPI-patible serial interface is controlled by the CS and SCLK signals.
