3 Description

The AMC1336 is a precision, delta-sigma (ΔΣ)

modulator with the output separated from the input

circuitry by a capacitive double 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 VDE V 0884-11 and

UL1577 standards. Used in conjunction with isolated

power supplies, this isolated modulator separates

parts of the system that operate on different commonmode

voltage levels and protects lower-voltage parts

from damage.

The unique wide, bipolar. ±1-V input voltage range of

the AMC1336 and its high input resistance support

direct connection of the device to resistive dividers in

high-voltage applications. When used with a digital

filter (for instance, as integrated in the

TMS320F28004x, TMS320F2807x or TMS320F2837x

microcontroller families) to decimate the output

bitstream, the device can achieve 16 bits of resolution

with a dynamic range of 87 dB at a data rate of

82 kSPS.

On the high-side, the AMC1336 is supplied by a

3.3-V or 5-V power supply. The isolated digital

interface operates from a 3.0-V, 3.3-V or 5-V power

supply.

The AMC1336 performance is specified over the

extended industrial temperature range of –40°C to

+125°C.
