2.7V-5.25V Digital, 5V Analog, 12 Bit, 4MSPS, Parallel ADC With Ref

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 a 48-pin TQFP package.
