AMC1203PSAR Datasheet PDF - TI

●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.
