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 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
information can be reconstructed with an appropriate digital
filter to achieve 88 dB signal to noise ratio (SNR) at 78.1 kSPS.
The serial input/output can use a 5 V or a 3 V supply (VDD2).
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.
