ADS7280 - Analog-to-Digital Converter

Download the ADS7280 datasheet PDF. This datasheet also covers the ADS7279 variant, as both devices belong to the same analog-to-digital converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The ADS7279 is a low-power, 14-bit, 1MSPS analog-to-digital converter (ADC) with a unipolar input.

The device includes a 14-bit, capacitor-based successive approximation register (SAR) ADC with inherent sample-and-hold.
