The ADS8324 is a 14-bit, sampling Analog-to-Digital (A/D) converter with tested specifications using a 1.8V supply voltage. It requires very little power, even when operating at the full 50kHz 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 1mW at 10kHz data rate.
The ADS8324 also features 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/2.
Ultra-low power and small size make the ADS8324 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 ADS8324 is available in an MSOP-8 package.
