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.
