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.
- DC-DC converter
- On-board chargers

Evaluation Kits (1)
The EVAL-ADuM4195-1EBZ is a compact isolated DC voltage monitoring board with an isolated on-board power supply to facilitate the setup and testing of the performance characteristics of the ADUM4195-1.
On the input side of the board, two separate inputs are available: The P1000 input is pre-configured to accept up to 1 kV DC, while the P200 input can be user-configured for voltages up to 200 V DC. Additional connectors provide access to the isolated 5 V DC supply and the shutdown (SD) input of the ADUM4195-1.
On the output side of the board, the output of the ADUM4195-1 is directly accessible (pre-configured) or may be first-order low-pass filtered by adding a resistor and a capacitor. A single 5 V DC supply is sufficient to power both the input and output side of the board, while the optional power disable (PDIS) pin can be used to disable the on-board supply in applications where low-power consumption is at premium.
Full specifications for the ADuM4195-1 are available in the ADuM4195-1 data sheet, which must be consulted in conjunction with the user guide when working with the EVAL-ADuM4195-1EBZ.
