DESCRIPTION
The ADS8321 is a 16-bit sampling analog-to-digital converter
(ADC) with tested specifications over a 4.75V 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 1mW at 10kHz data rate.
The ADS8321 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 ADS8321 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 ADS8321 is available in an MSOP-8 package.
