The AMC0136 is a precision, galvanically isolated delta-sigma (ΔΣ) modulator with a ±1V, high impedance input and external clock. The high-impedance input is optimized for connection to high-impedance 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.
