This barrier • Low Offset Error: 1.5 mV Maximum has been certified to provide galvanic isolation of up to 4250 VPEAK (AMC1200B) or 4000 VPEAK • Low Noise: 3.1 mVRMS Typical (AMC1200) according to UL1577 and VDE V 0884- • Low High-Side Supply Current: 10. Used in conjunction with isolated power supplies, 8 mA Maximum at 5 V these devices prevent noise currents on a high • Input Bandwidth: 60 kHz Minimum common mode voltage line from entering the local ground and interfering with or damaging sensitive • Fixed Gain: 8 (0.5% accuracy) circuitry. • High Common Mode Rejection Ratio: 108 dB The input of the AMC1200 or AMC1200B is optimized • 3.3-V Operation on Low-Side for direct connection to shunt resistors or other low • Certified Galvanic Isolation: voltage level signal sources. The excellent – UL1577 and VDE V 0884-10 Approved performance of the device supports accurate current control resulting in system-level power saving and, – Isolation Voltage: 4250 VPEAK (AMC1200B) especially in motor-control applications, lower torque – Working Voltage: 1200 VPEAK ripple. The common mode voltage of the output – Transient Immunity: 10 kV/µs Minimum signal is automatically adjusted to either the 3-V or 5-V low-side supply. • Typical 10-Year Lifespan at Rated Working Voltage (see Application Report SLLA197) The AMC1200 and AMC1200B are fully specified • Fully Specified Over the Extended Industrial over the extended industrial temperature range of Temperature Range –40°C to 105°C and are available in a wide-body SOIC-8 package (DWV) and a gullwing-8 package (DUB). 2 Applications • Shunt Resistor Based Current Sensing in: Device Information(1) – Motor Control PART NUMBER PACKAGE BODY SIZE (NOM) – Green Energy SOP (8) 9.50 mm × 6.57 mm AMC1200, AMC1200B – Frequency Inverters SOIC (8) 5.85 mm × 7.50 mm – Uninterruptible Power Supplies (1) For all available packages, see the orderable addendum at the end of the data sheet.
