3 Description
The AMC1333M10 is a precision, delta-sigma (ΔΣ)
modulator with the output separated from the input
circuitry by an isolation barrier that is highly resistant
to magnetic interference. This barrier is certified to
provide reinforced isolation of up to 8000 VPEAK
according to the DIN EN IEC 60747-17 (VDE
0884-17) and UL1577 standards, and supports a
working voltage up to 1.5 kVRMS. The isolation barrier
separates parts of the system that operate on different
common-mode voltage levels and protects the lowvoltage
side from voltages that can cause electrical
damage or be harmful to an operator.
The wide, bipolar, ±1-V input voltage range of the
AMC1333M10 and its high input resistance support
direct connection of the device to resistive dividers
in high-voltage applications. The output bitstream of
the AMC1333M10 is synchronized to the internally
generated clock. By using an integrated digital
filter (such as those in the TMS320F2807x or
TMS320F2837x microcontroller families) to decimate
the bitstream, the device can achieve 16 bits of
resolution with a dynamic range of 87 dB at a data
rate of 39 kSPS.
The AMC1333M10 is offered in a 8-pin, wide-body,
SOIC package and is fully specified over the extended
industrial temperature range of –40°C to +125°C.
