Analog Devices Inc. ADuM4195-1 Isolated Amplifiers
Analog Devices ADuM4195-1 Isolated Amplifiers utilize ADI's iCoupler® technology. The series features low offset and gain error, suitable for many isolated voltage sensing applications. The amplifier transfer function does not change over the lifetime and is stable over a wide temperature range of -40°C to +125°C. This differs from optocoupler-based solutions, which have an uncertain current transfer ratio over a lifetime and are unstable at high temperatures. ADI ADuM4195-1 amplifiers are certified to deliver galvanic isolation up to 5kVRMS according to UL1577 and are housed in a tiny 8-lead comprehensive body SOIC package with increased creepage.
