ADuM3195 Isolated Amplifier

Analog Devices' ADUM3195 isolated amplifiers have adjustable gain and single-ended output

Image of Analog Devices' ADuM3195 Isolated AmplifierADI's ADuM3195 are isolation amplifiers based on ADI's iCoupler® technology. They have very low offset and gain error, making them ideal for many isolated voltage sensing applications.

Unlike optocoupler-based solutions, which have an uncertain current transfer ratio over their lifetime and at high temperatures, the ADuM3195 transfer functions do not change over their lifetime and are stable over a wide temperature range of -40°C to +125°C.

Included in the ADuM3195 are wideband operational amplifiers useful for a variety of commonly used applications. Included in the ADuM3195 are two high-accuracy 2.5 V reference outputs.

The ADuM3195 is packaged in a 16-lead quarter small outline package (QSOP) for a 3000 VRMS isolation voltage rating.

The EVAL-ADuM3195EBZ is a compact isolated DC and AC (configurable) voltage monitoring board with an isolated on-board power supply to facilitate the setup and testing of the performance characteristics of the ADuM3195.
