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.

Simultaneous 50 Hz/60 Hz rejection

4 general-purpose digital outputs

Power supply

AV_DD: 3 V to 5.25 V

DV_DD: 2.7 V to 5.25 V

Current: 4.65 mA

Temperature range: −40°C to +105°C

28-lead TSSOP and 32-lead LFCSP packages

Interface

3-wire serial

SPI, QSPI™, MICROWIRE™, and DSP compatible

Schmitt trigger on SCLK

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.

APPLICATIONS

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.
