# Input Channels

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 2 mW at a 200-kHz throughput rate and a 5-V supply. The reference voltage (VREF) can be varied between 100 mV and VCC, providing a corresponding input voltage range of 0 V to VREF. The device includes a shutdown mode that reduces power dissipation to under 15 µW. The ADS7841 is specified down to 2.7-V operation.

Low power, high speed, and on-board multiplexer make the ADS7841 ideal for battery-operated systems. The serial interface also provides low-cost isolation for remote data acquisition. The ADS7841 is available in a SSOP-16 package and is specified over the –40°C to 85°C temperature range.
