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 VPEAKaccording 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 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 theTMS320F28004x,TMS320F2807xorTMS320F2837xmicrocontroller 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 a3.3-V or 5-V power supply. The isolated digital interface operates from a 3.0-V, 3.3-V or 5-V power supply.Read more
