DESCRIPTION  
The ADS7881 is a 12-bit 4-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 12-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 48-pin  
TQFP and QFN packages.
