DESCRIPTION

The ADS8320 is a 16-bit sampling analog-to-digital converter with guaranteed specifications over a 2.7V to 5.25V supply range. It requires very little power even when operating at the full 100kHz data rate. At lower data rates, the high speed of the device enables it to spend most of its time in the power-down mode— the average power dissipation is less than 100µW at 10kHz data rate.

The ADS8320 also features operation from 2.0V to 5.25V, a synchronous serial (SPI/SSI compatible) interface, and a differential input. The reference voltage can be set to any level within the range of 500mV to VCC.

Ultra-low power and small size make the ADS8320 ideal for portable and battery-operated systems. It is also a perfect fit for remote data acquisition modules, simultaneous multi-channel systems, and isolated data acquisition. The ADS8320 is available in an 8-lead MSOP package.
