ADS7044 Datasheet - Texas Instruments

ADS7044 12-Bit 1-MSPS SAR ADC

The ADS7044 is a 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 controlle.
