ADS7042 Datasheet (Texas Instruments)

ADS7042, 12-Bit 1-MSPS SAR ADC

The ADS7042 is a 12-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-compatible serial interface is con
