Featured Products
ADUM3195 and EVAL-ADUM3195 Evaluation Board
ADUM3195
Isolated Amplifier with Adjustable Gain and Single-Ended Output
The ADuM3195 are isolation amplifiers based on Analog Devices, Inc., iCoupler® technology. The ADuM3195 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 lifetime and at high temperatures, the ADuM3195 transfer functions do not change over lifetime, and are stable over a wide temperature range of −40°C to +125°C.
APPLICATIONS
- Inverters
- DC to DC converters
- On-board chargers
EVAL-ADUM3195
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.
