AMC1203 Datasheet Isolated Delta-sigma Modulator

Manufacturer: Texas Instruments

Overview: AMC1203 www.ti.com SBAS427C – FEBRUARY 2008 – REVISED JUNE 2011 1-Bit, 10MHz, 2nd-Order, Isolated Delta-Sigma Modulator Check for Samples:.

General Description

The AMC1203 is a 1-bit, 10MHz, isolated delta-sigma (ΔΣ) modulator with an output buffer separated from the input interface circuitry by a silicon dioxide (SiO2) isolation barrier.

This barrier provides galvanic isolation of up to 4000VPEAK.

Used in conjunction with isolated power supplies, these devices prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry.
