The ADS7251 and ADS7851 belong to a family of pin-compatible, dual, high-speed, simultaneous-sampling, analog-to-digital converters (ADCs) that support fully-differential analog inputs and feature two independent internal voltage references. The ADS7251 offers 12-bit resolution and up to 2-MSPS sampling speed. The ADS7851 offers 14-bit resolution and up to 1.5-MSPS sampling speed.
The devices support a wide digital supply voltage range, allowing easy communication with a variety of digital host controllers using a simple, serial interface. Both devices are fully specified over the extended industrial temperature range (–40°C to +125°C) and are available in a pin-compatible, space-saving, WQFN-16 (3-mm × 3-mm) package.
