Texas Instruments ADS7854IPW

Description
The ADS8354, ADS7854, and ADS7254 are pin-compatible, dual, high-speed, simultaneous-sampling analog-to-digital converters (ADCs) that support fully-differential analog inputs. Each device includes two individually programmable reference sources for system-level gain calibration. A flexible serial interface enables communication with various host controllers. Power consumption can be optimized using two low-power modes. The devices are fully specified over the extended industrial temperature range (-40°C to 125°C) and are available in WQFN-16 (3-mm x 3-mm) and TSSOP-16 packages.
