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

shutdown mode that reduces power dissipation to under

15

µW. 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 log-

gers, 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 en-

sured over the –40

°C to +85°C temperature range.
