3 Description

The AMC0136 is a precision, functionally isolated,

delta-sigma modulator with a high-impedance input

and a ±1V input voltage range. The isolation barrier

separates parts of the system that operate on different

common-mode 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 high input impedance,

the AMC0136 is designed for high accuracy, isolated

voltage sensing in space-constrained applications.

The galvanic isolation barrier supports high commonmode

transients and allows for isolating sensitive

control circuitry from switching noise from the power

stage.

The output bitstream of the AMC0136 is synchronized

to an external clock. Combined with a sinc3, OSR 256

filter, the device achieves 16 bits of resolution with an

89dB dynamic range and a 39kSPS data rate.

The AMC0136 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.
