Description

The ADS7826/27/29 is a family of 10/8/12-bit sampling analog-to-digital converters (A/D) with assured specifi- cations at 2.7-V supply voltage. It requires very little power even when operating at the full sample rate. At lower conversion rates, the high speed of the device enables it to spend most of its time in the power down mode- the power dissipation is less than 60 µW at 7.5 kHz.

The ADS7826/27/29 also features operation from 2.0 V to 5 V, a synchronous serial interface, and a differential input. The reference voltage can be set to any level within the range of 50mV to V_CC.

Ultra-low power and small package size make the ADS7826/27/29 family ideal for battery operated systems It is also a perfect fit for remote data acquisition modules, simultaneous multichannel systems, and iso- lated data acquisition. The product is available in a 3 x 3 8-pin PDSO (SON, same size as QFN) package.
