ADS7841E/2K5G4

12Bit, 4Channel Serial Output Sampling Analog-to-Digital Converter 16-SSOP -40℃ to 85℃

DESCRIPON

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.
