DESCRIPTION

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 refer-

ence voltage can be set to any level within the range of

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, simulta-

neous multi-channel systems, and isolated data acquisi-

tion. The ADS8324 is available in an MSOP-8 package.
