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 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 which reduces power dissipation to under
15μW. The ADS7841 is tested down to 2.7V operation.
Low power, high speed, and on-board multiplexer make the
ADS7841 ideal for battery-operated systems such as personal
digital assistants, portable multi-channel data loggers,
and measurement equipment. The serial interface also provides
low-cost isolation for remote data acquisition. The
ADS7841 is available in a DIP-16.
