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
or 12 bits. Typical power dissipation is 2mW at a
200kHz throughput rate and a +5V supply. The refer-
ence voltage (V
) can be varied between 100mV and
V
, providing a corresponding input voltage range of
0V to V
. The device includes a shutdown mode
which reduces power dissipation to under 15
μ
W. 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 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 16-pin PDIP or a 16-lead SSOP package and is
guaranteed over the –40
°
C to +85
°
C temperature range.
