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.
