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 shut-
down 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 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.
