3 Description
The AMC0106M05 is a precision, functionally
isolated, delta-sigma modulator with a ±50mV 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 AMC0106M05 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 AMC0106M05 is
synchronized to an external clock. Combined with a
sinc3, OSR 256 filter, the device achieves 16 bits
of resolution with an 82.5dB dynamic range and a
78kSPS data rate.
The AMC0106M05 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.
