Texas Instruments ADS7890IPFBT

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.
