ADS7253 SAR ADC

ADS7253 SAR ADC

Texas Instruments' ADS7253 belongs to a family of pin-compatible, dual, high-speed, simultaneous-sampling, analog-to-digital converters (ADCs) that support single-ended and pseudo-differential analog inputs.

This device includes two individually programmable reference sources that can be used for system-level gain calibration. Also, a flexible serial interface that can operate over a wide power-supply range enables easy communication with a large variety of host controllers. Power consumption for a given throughput can be optimized by using the two low-power modes supported by the device. It is fully specified over the extended industrial temperature range (–40°C to 125°C) and is available in a pin-compatible, WQFN-16 (3 × 3 mm) package.
