GENERAL DESCRIPTION
The AD7193 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 four differential inputs or
eight pseudo differential inputs. The on-chip channel sequencer
allows several channels to be enabled simultaneously, and the
AD7193 sequentially converts on each enabled channel, simplifying
communication with the part. 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. The AD7193 also
includes a zero latency option.
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 available in a 28-lead
TSSOP package and a 32-lead LFCSP package.
