4.8 kHz, Ultralow Noise, 24-Bit

Sigma-Delta ADC with PGA

AD7192

Temperature measurement

FEATURES

Chromatography

PLC/DCS analog input modules

Data acquisition

RMS noise: 11 nV @ 4.7 Hz (gain = 128)

15.5 noise-free bits @ 2.4 kHz (gain = 128)

Up to 22 noise-free bits (gain = 1)

Offset drift: 5 nV/°C

Medical and scientific instrumentation

Gain drift: 1 ppm/°C

Specified drift over time

GENERAL DESCRIPTION

The AD7192 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 be interfaced directly to the ADC.

2 differential/4 pseudo differential input channels

Automatic channel sequencer

Programmable gain (1 to 128)

Output data rate: 4.7 Hz to 4.8 kHz

Internal or external clock

The device can be configured to have two differential inputs or

four pseudo differential inputs. The on-chip channel sequencer

allows several channels to be enabled, and the AD7192 sequentially

converts on each enabled channel. This simplifies 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: 4.35 mA

Temperature range: –40°C to +105°C

Package: 24-lead TSSOP

The device has two digital filter options. The choice of filter

affects the rms noise/noise-free resolution at the programmed

output data rate, the settling time, and the 50 Hz/60 Hz

rejection. For applications that require all conversions to be

settled, the AD7192 includes a zero latency feature.

INTERFACE

3-wire serial

SPI, QSPI™, MICROWIRE™, and DSP compatible

Schmitt trigger on SCLK

APPLICATIONS

The part operates with a power supply from 3 V to 5.25 V. It

consumes a current of 4.35 mA. It is housed in a 24-lead TSSOP

package.
