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.

The ADS7280 is based on the same core and includes a 2-to-1 input MUX with a programmable TAG bit output option. Both the ADS7279 and ADS7280 offer a high-speed, wide voltage serial interface, and are capable of daisy-chain mode operation when multiple converters are used.

These converters are available in 4 × 4 QFN and TSSOP-16 packages, and are fully specified for operation over the industrial -40°C to +85°C temperature range.
