The serial input/output can use a 5 V or a 3 V supply (VDD2).  
GENERAL DESCRIPTION  
The AD74031 is a high performance, second-order, Σ-Δ modulator  
that converts an analog input signal into a high speed, single-bit  
data stream, with on-chip digital isolation based on Analog  
Devices, Inc., iCoupler® technology. The device operates from a  
5 V (VDD1) power supply and accepts a differential input signal  
of 250 mV ( 320 mV full-scale). The differential input is ideally  
suited to shunt voltage monitoring in high voltage applications  
where galvanic isolation is required.  
The serial interface is digitally isolated. High speed complementary  
metal oxide semiconductor (CMOS) technology, combined with  
monolithic transformer technology, means the on-chip isolation  
provides outstanding performance characteristics, superior to  
alternatives such as optocoupler devices. The AD7403 device is  
offered in a 16-lead, wide-body SOIC package and has an oper-  
ating temperature range of −40°C to +125°C. The AD7403-8  
device is offered in an 8-lead, wide-body SOIC package and has  
an operating temperature range of −40°C to +105°C.  
The analog input is continuously sampled by a high performance  
analog modulator, and converted to a ones density digital output  
stream with a data rate of up to 20 MHz. The original
