Description
AI
The ADuM4195-1 is an isolation amplifier based on Analog Devices, Inc.,iCoupler®technology. The ADuM4195-1 has very low offset and gain error, making it ideal for many isolated voltage sensing applications.Unlike optocoupler-based solutions, which have an uncertain current transfer ratio over a lifetime and is unstable at high temperatures, the ADuM4195-1 transfer function does not change over its lifetime, and is stable over a wide temperature range of −40°C to +125°C.The ADuM4195-1 has been certified to provide galvanic isolation up to 5 kV rms according to UL1577.The ADuM4195-1 is packaged in a small 8-lead wide body SOIC package with increased creepage.APPLICATIONSInvertersDC-DC converterOn-board chargers
