DESCRIPTION

The ADS8345 is an 8-channel, 16-bit, sampling

Analog-to-Digital (A/D) converter with a synchronous serial

interface. Typical power dissipation is 8mW at a 100kHz

throughput rate and a +5V supply. The reference voltage

(VREF) can be varied between 500mV and VCC/2, providing a

corresponding input voltage range of ±VREF. The device

includes a shutdown mode which reduces power dissipation

to under 15μW. The ADS8345 is ensured down to 2.7V

operation.

Low-power, high-speed, and an onboard multiplexer make

the ADS8345 ideal for battery-operated systems such as

personal digital assistants, portable multi-channel data loggers,

and measurement equipment. The serial interface also

provides low-cost isolation for remote data acquisition. The

ADS8345 is available in a QSOP-20 or SSOP-20 package

and is ensured over the –40°C to +85°C temperature range.
