The ADS7841 is a 4-channel, 12-bit sampling analogto-
digital converter (ADC) with a synchronous serial
interface. The resolution is programmable to either 8
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 15mW. The
ADS7841 is guaranteed 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 multichannel
data loggers, and measurement equipment.
The serial interface also provides low-cost isolation
for remote data acquisition. The ADS7841 is available
in a 16-pin PDIP or a 16-lead SSOP package and is
guaranteed over the –40°C to +85°C temperature range.
