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.
