ADS7822-Q1 - Automotive 12-Bit, 200kSPS Micro Power Sampling Analog-To-Digital Converter

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 mode—the 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 V_CC.

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.
