General Description
AD7738 General Description
The AD7738 is a high precision, high throughput analog frontend. True 16-bit p-p resolution is achievable with a total con-version time of 117 s (8.5 kHz channel switching), making it ideally suitable for high resolution multiplexing applications.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 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 and accepts a common-mode input voltage from 200 mV above AGND to AVDD 300 mV.The multiplexer output is pinned out externally, allowing the user to implement programmable gain or signal conditioning before applying the input to the ADC.The differential reference input features "No-Reference" detect capability. The ADC also supports per channel system calibra-tion options.
The digital serial interface can be configured for 3-wire opera-tion 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 40C to +105C.Other parts in the AD7738 family are the AD7734 and the AD7732.
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 while not degrading the performance of the adjacent channels. The AD7732 is similar to AD7734, but its analog front end features two fully differential input channels.
