ADS7043 Datasheet (Texas Instruments)

ADS7043, 12-Bit 1-MSPS SAR ADC

The ADS7043 is a 1-MSPS, analog-to-digital converter (ADC).

The device supports a wide analog input voltage range (±0.825 V to ±1.8 V) and includes a capacitor-based, successive-approximation register (SAR) ADC with an inherent sample-and-hold circuit.

The SPI-compatible serial interface is controll
