ADS7841 Datasheet PDF

●DESCRIPTION

●The ADS7841 is a 4-channel, 12-bit sampling Analog-to Digital Converter (ADC) with a synchronous serial interface. The resolution is programmable to either 8 bits or 12 bits. Typical power dissipation is 2mW at a 200kHz through put rate and a +5V supply. The reference voltage (VREF) can be varied between 100mV and VCC, providing a correspond ing input voltage range of 0V to VREF. The device includes a shutdown mode which reduces power dissipation to under 15µW. The ADS7841 is tested down to 2.7V operation.
