Industrial instrumentation

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.

The part is specified for operation over the extended industrial

temperature range of –40°C to +105°C.

GENERAL DESCRIPTION

The AD7739 is a high precision, high throughput analog front

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

conversion time of 250 µs (4 kHz channel switching), making it

ideally suited to high resolution multiplexing applications.

Other parts in the AD7739 family are the AD7738, AD7734,

and AD7732.

The AD7738 is similar to the AD7739 but has higher speed

(8.5 kHz channel switching for 16-bit performance) and higher

AIN leakage current. 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 part can be configured via a simple digital interface, which

allows users to balance the noise performance against data

throughput up to 15 kHz.

The analog front end features eight single-ended or four fully

differential input channels with unipolar or bipolar 625 mV,

1.25 V, and 2.5 V input ranges. It accepts a common-mode input

voltage from 200 mV above AGND to AV_DD– 300 mV.

The AD7734 analog front end features four single-ended input

channels with unipolar or true bipolar input ranges to 10 V

while operating from a single +5 V analog supply. The AD7734

accepts an analog input overvoltage to 16.5 V without

degrading the performance of the adjacent channels.

The differential reference input features “No-Reference” detect

capability. The ADC also supports per channel system

calibration options.

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

features two fully differential input channels.
