The ADS8343 is a 4-channel, 16-bit sampling Analog-toDigital (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 15W. The ADS8343 is ensured down to 2.7V operation.
