SAR ADC, Dual, 1 MSPS, 14 Bit, Simultaneous Sampling

SAR ADC, Dual, 1 MSPS, 14 Bit, Simultaneous Sampling - ADS7853
 

Description

The ADS8353, ADS7853, and ADS7253 belong 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.

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