GENERAL DESCRIPTION
The AD7194 is a low noise, complete analog front end for high
precision measurement applications. It contains a low noise,
24-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC).
The on-chip low noise gain stage means that signals of small
amplitude can interface directly to the ADC.
The device can be configured to have eight differential inputs or
sixteen pseudo differential inputs. The on-chip 4.92 MHz clock
can be used as the clock source to the ADC or, alternatively, an
external clock or crystal can be used. The output data rate from
the part can be varied from 4.7 Hz to 4.8 kHz.
The device has a very flexible digital filter, including a fast
settling option. Variables such as output data rate and settling
time are dependent on the option selected. For applications that
require all conversions to be settled, the AD7194 includes zero
latency.
The part operates with a power supply from 3 V to 5.25 V. It
consumes a current of 4.65 mA, and it is housed in a 32-lead
LFCSP package.
