Isolated Sigma-Delta Modulator

AD7401

FEATURES

GENERAꢀ DESCRIPTION

The AD7401¹is a second-order, Σ-Δ modulator that converts

an analog input signal into a high speed 1-bit data stream with

on-chip digital isolation based on Analog Devices’ iCoupler®

technology. The AD7401 operates from a 5 V power supply and

accepts a differential input signal of ±±00 mV ꢀ±(±0 mV full-

scale). The analog input is continuously sampled by the analog

modulator, eliminating the need for external sample-and-hold

circuitry. The input information is contained in the output

stream as a density of 1s with a data rate up to 16 MHz. The

original information can be reconstructed with an appropriate

digital filter. The serial I/O can use a 5 V or ( V supply ꢀV_DD±).

V_IORM= 891 V peak

The serial interface is digitally isolated. High speed CMOS,

combined with monolithic air core transformer technology,

means the on-chip isolation provides outstanding performance

characteristics, superior to alternatives such as optocoupler

devices. The part contains an on-chip reference. The AD7401

is offered in a 16-lead SOIC_W and has an operating

temperature range of −40°C to +105°C.
