The AMC1336-Q1 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 common-mode voltage levels and protects lower-voltage parts from damage.

The unique wide, bipolar. ±1-V input voltage range of theAMC1336-Q1 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-Q1 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-Q1 performance is specified over the extended industrial temperature range of –40°C to +125°C.
