The ADS7822 is a 12-bit sampling analog-to-digital (A/D) converter with ensured specifications over a 2.7-V to 5.25-V supply range. It requires very little power even when operating at the full 200-kHz rate. At lower conversion rates, the high speed of the device enables it to spend most of its time in the power-down modethe power dissipation is less than 60 µW at 7.5 kHz.
The ADS7822 also features operation from 2.0 V to 5 V, a synchronous serial interface, and a pseudo-differential input. The reference voltage can be set to any level within the range of 50 mV to VCC.
Ultra low power and small size make the ADS7822 ideal for battery-operated systems. It is also a perfect fit for remote data-acquisition modules, simultaneous multichannel systems, and isolated data acquisition. The ADS7822 is available in an MSOP-8 package.
