Isolation Amplifiers Possess High CMR
Meeting 8 mm creepage and clearance requirements, Avago Technologies’ ACPL-C780, ACPL-C780, and ACPL-C784 isolation amplifiers present a CMR of 15 kV/µs at 1,000 V VCM. The SO-8-packaged components display gain temperature drift of 0.00025 V/V/°C, input offset voltage of 0.30000 mV, and 0.00040% nonlinearity using advanced sigma-delta A/D converter technology. Typical applications include inverter current sensing, motor phase and rail current sensing, motor rail voltage sensing, switching power supply signal isolation, industrial A/D converters, and general-purpose current sensing and monitoring. The units have reinforced insulation with IEC/EN/DIN EN 60747-5-2, UL 1577, and CSA approvals. Pricing starts at $6.00, $4.25, and $3.13 each, respectively, in 10,000 quantities.
