3 Description

The AMC0136 is a precision, galvanically isolated

delta-sigma (ΔΣ) modulator with a ±1V, high

impedance input and external clock. The highimpedance

input is optimized for connection to highimpedance

resistive dividers or other voltage signal

sources with high output resistance.

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 output bitstream of the AMC0136 is synchronized

to an external clock. Combined with a sinc3, OSR

256 filter, the device achieves 14.8 effective bits of

resolution or 89dB of dynamic range, at a sample rate

of 39kSPS.

The AMC0136 is available in a 8-pin, 0.65mm

pitch VSON package and is fully specified over the

temperature range from –40°C to +125°C.
