The ADS7822P is a 12-bit sampling Analog-to-digital Converter (ADC) with ensured specifications over a 2.7 to 5.25V supply range. It requires very little power even when operating at the full 200kHz 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 60μW at 7.5kHz. The ADC also features operation from 2 to 5V, a synchronous serial interface and a pseudo-differential input. The reference voltage can be set to any level within the range of 50mV to VCC. Ultra low power and small size make the ADC ideal for battery-operated systems. It is also a perfect fit for remote data-acquisition modules, simultaneous multichannel systems and isolated data acquisition.
