2.7V-5.25V Digital, 5V Analog, 14 Bit, 1.25 MSPS, Serial ADC W/Ref

The ADS7890 is a 14-bit 1.25-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 serial SPI or DSP compatible Interface 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. The device operates at lower power when used at lower conversion rates because of the nap feature. The device is available in a 48-pin TQFP package.
