ADS7844 - 12-Bit/ 8-Channel Serial Output Sampling ANALOG-TO-DIGITAL CONVERTER
The ADS7844 is an 8-channel, 12-bit sampling analog-todigital converter (ADC) with a synchronous serial interface.
Typical power dissipation is 3mW at a 200kHz throughput rate and a +5V supply.
The reference voltage (VREF) can be varied between 100mV and VCC, providing a corresponding input voltage
