3 Description

The AMC0106M25 is a precision, functionally

isolated, delta-sigma modulator with a ±250mV input

voltage range. The isolation barrier separates parts

of the system that operate on different commonmode

voltage levels. The isolation barrier supports

a working voltage up to 200VRMS / 280VDC and

transient overvoltages up to 570VRMS / 800VDC.

With a small package size and low input

voltage range, the AMC0106M25 is designed for

high accuracy, isolated current sensing in spaceconstrained

applications. The galvanic isolation

barrier supports high common-mode transients and

allows for isolating sensitive control circuitry from

switching noise from the power stage.

The output bitstream of the AMC0106M25 is

synchronized to an external clock. Combined with a

sinc3, OSR 256 filter, the device achieves 16 bits of

resolution with an 86dB dynamic range and a 78kSPS

data rate.

The AMC0106M25 is available in an 8-pin, 0.65mm

pitch VSON package and is specified over the

extended industrial temperature range of –40°C to

+125°C.
