DESCRIPTION
The ADS8320 is a 16-bit, sampling analog-to-digital (A/D)
converter with ensured specifications over a 2.7V to 5.25V
supply range. It requires very little power even when operat-
ing 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 100mW 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 V_CC.
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, simulta-
neous multi-channel systems, and isolated data acquisi-
tion. The ADS8320 is available in an MSOP-8 package.
