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 common-mode 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.
