Description
AD7731BN Overview
The analogue to digital converter is designed with 24 Bits.The AD converter is embedded in the 24-DIP (0.300, 7.62mm) package.The ADC converter is packaged in the way of Tube.This electronic AD converter is mounted in the way of Through Hole.When operating, analogue to digital converter's operating temperature should be kept at -40°C~85°C.The number of samples of audio recorded every second is 6.4k Hz.The input type of this electronic AD converter is Differential.There are External reference types differentiated on the way by which they are garbage collected. This electronic digital converter is configured in such a way that MUX-PGA-ADC.The architecture that analogue to digital converter's core adopts is Sigma-Delta.The supply/analog voltage of this electrical ADC converter is 5V, which converts alternative voltage (AC voltage) to regulated direct voltage (DC voltage) and provide regulated DC power in order to drive a load.The supply/digital voltage of this electrical AD converter is 5V.3, 5 inputs are employed.There are 1 A/D converters, which are used to convert an analog signal like voltage to digital form so that it can be read and processed by a microcontroller. PGA can be ensured when operating.It employs 24-PDIP as its supplier device package.

The AD7731 is a complete analog front-end for process control applications. The device has a proprietary programmable gain front end that allows it to accept a range of input signal ranges, including low level signals, directly from a transducer. The sigmadelta architecture of the part consists of an analog modulator and a low pass programmable digital filter, allowing adjustment of filter cutoff, output rate and settling time. The part features three buffered differential programmable gain analog inputs (which can be configured as five pseudo-differential inputs), as well as a differential reference input. The part operates from a single 5 V supply and accepts seven unipolar analog input ranges: 0 to 20 mV, 40 mV, 80 mV, 160 mV, 320 mV, 640 mV and 1.28 V, and seven bipolar ranges: ±20 mV, ±40 mV, ±80 mV, ±160 mV, ±320 mV, ±640 mV and ±1.28 V. The peak-to-peak resolution achievable directly from the part is 16 bits at an 800 Hz output rate. The part can switch between channels with 1 ms settling time and maintain a performance level of 13 bits of peak-to-peak resolution. The serial interface on the part can be configured for three-wire operation and is compatible with microcontrollers and digital signal processors. The AD7731 contains self-calibration and system calibration options and features an offset drift of less than 5 nV/°C and a gain drift of less than 2 ppm/°C. The part is available in a 24-lead plastic DIP, a 24-lead SOIC and 24-lead TSSOP package. Applications Process Control PLCs/DCS Industrial Instrumentation
