DESCRIPTION  
The ADS7891 is a 14-bit 3-MSPS A-to-D converter with 2.5-V internal reference. The device includes a  
capacitor based SAR A/D converter with inherent sample and hold. The device offers a 14-bit parallel interface  
with an additional byte mode that provides easy interface with 8-bit processors. The device has a  
pseudo-differential input stage.  
The −IN swing of 200 mV is useful to compensate for ground voltage mismatch between the ADC and sensor  
and also to cancel common-mode noise. With nap mode enabled, the device operates at lower power when  
used at lower conversion rates. The device is available in a 48-pin TQFP package.
