Description

 

The ADS7844E/2K5  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 range of 0V to VREF. The device includes a shutdown mode that reduces power dissipation to under 1μW. The ADS7844E/2K5 is ensured down to 2.7V operation.
