This barrier has been certified • Low Offset Error: 1.5 mV max to provide galvanic isolation of up to 4250 VPEAK, according to UL1577 and IEC60747-5-2. Used in • Low Noise: 3.1 mVRMS typ conjunction with isolated power supplies, this device • Low High-Side Supply Current: prevents noise currents on a high common-mode 8 mA max at 5 V voltage line from entering the local ground and • Input Bandwidth: 60 kHz min interfering with or damaging sensitive circuitry. • Fixed Gain: 8 (0.5% Accuracy) The AMC1100 input is optimized for direct connection to shunt resistors or other low voltage level signal • High Common-Mode Rejection Ratio: 108 dB sources. The excellent performance of the device • Low-Side Operation: 3.3 V enables accurate current and voltage measurement • Certified Galvanic Isolation: in energy-metering applications. The output signal – UL1577 and IEC60747-5-2 Approved common-mode voltage is automatically adjusted to either the 3-V or 5-V low-side supply. – Isolation Voltage: 4250 VPEAK The AMC1100 is fully specified over the extended – Working Voltage: 1200 VPEAK industrial temperature range of –40°C to +105°C and – Transient Immunity: 2.5 kV/µs min is available in the SMD-type, gullwing-8 package. • Typical 10-Year Lifespan at Rated Working Voltage (see Application Report SLLA197) • Fully Specified Over the Extended Industrial Temperature Range APPLICATIONS • Shunt Resistor Based Current Sensing in: – Energy Meters – Green Energy – Power Measurement Applications 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
