DESCRIPTION

The ADS8341 is a 4-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, providing a corresponding

input voltage range of 0V to VREF. The device includes a

shutdown mode that reduces power dissipation to under

15μW. The ADS8341 is tested down to 2.7V operation.

Low power, high speed, and an onboard multiplexer make

the ADS8341 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

ADS8341 is available in an SSOP-16 package and is ensured

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