DESCRIPTION

The ADS8343 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

input voltage range of

±V

down mode which reduces power dissipation to under 15

µW.

The ADS8343 is ensured down to 2.7V operation.

Low power, high speed, and an onboard multiplexer make

the ADS8343 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

ADS8343 is available in an SSOP-16 package and is en-

sured over the –40

°C to +85°C temperature range.
