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

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 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 loggers,

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 ensured

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