Texas Instruments ADS7882IPFBT

Description
The ADS7882 is a 12-bit, 3-MSPS analog-to-digital converter with a 2.5-V internal reference. It features a capacitor-based SAR architecture with inherent sample and hold. The device offers a 12-bit parallel interface with an additional byte mode for easy interfacing with 8-bit processors. It has a pseudo-differential input stage with a -IN swing of 200 mV, which compensates for ground voltage mismatch and cancels common-mode noise. The ADS7882 includes a nap mode for lower power consumption at lower conversion rates and a power-down mode for ultra-low power consumption. It is available in a 48-pin TQFP package.
