ADS7850 Simultaneous-Sampling ADC

ADS7850 Simultaneous-Sampling ADC

Texas Instruments' ADS7850 and ADS7250 belong to a family of pin-compatible, dual, high-speed, simultaneous-sampling, analog-to-digital converters (ADCs) that support pseudo-differential analog inputs. All devices support a simple serial interface that can operate over a wide power-supply range, enabling easy communication with a large variety of host controllers.

All devices are fully specified over the extended industrial temperature range (–40°C to +125°C) and are available in a pin-compatible, WQFN-16 (3 mm × 3 mm) package.
