Industrial instrumentation

The differential reference input features “No-Reference” detect

capability. The ADC also supports per channel system

calibration options. The digital serial interface can be

configured for 3-wire operation and is compatible with

microcontrollers and digital signal processors. All interface

inputs are Schmitt triggered.

GENERAL DESCRIPTION

The part is specified for operation over the extended industrial

temperature range of –40°C to +105°C.

The AD7732 is a high precision, high throughput analog front

end. True 16-bit p-p resolution is achievable with a total

conversion time of 500 µs (2 kHz channel switching), making it

ideally suitable for high resolution multiplexing applications.

Other parts in the AD7732 family are the AD7734 and

the AD7738.

The part can be configured via a simple digital interface, which

allows users to balance the noise performance against data

throughput up to a 15.4 kHz.

The AD7734 is similar to AD7732, but its analog front end

features four single-ended input channels.

The AD7738 analog front end is configurable for four fully

differential or eight single-ended input channels, features

0.625 V to 2.5 V bipolar/unipolar input ranges, and accepts a

common-mode input voltage from 200 mV to AVDD – 300 mV.

The AD7738 multiplexer output is pinned out externally,

allowing the user to implement programmable gain or signal

conditioning before being applied to the ADC.

The analog front end features two fully differential input

channels with unipolar or true bipolar input ranges to 10 V

while operating from a single +5 V analog supply. The part has

an overrange and underrange detection capability and accepts

an analog input overvoltage to 16.5 V without degrading the

performance of the adjacent channels.
