DESCRIPTIONThe 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.
