ISL3156EIUZ-T

ISL3156EIUZ-T is a galvanically isolated analog signal interface from Renesas Intersil (ISL3156 family). It conditions and transfers an analog signal from a primary (input) side to a secondary (output) side across an isolation barrier, providing safety and noise immunity in mixed-signal systems. The device uses separate supplies for each side and integrates the isolation barrier so there is no direct electrical path between input and output. It is commonly used to connect sensors/transducers to controllers in industrial automation, motor drives, power meters, and medical equipment where isolation is required.
Key points:
- Isolation between input and output
- Supports analog signaling with separate power domains
- 8-pin RoHS-compliant package; -T denotes tape-and-reel packaging (EIUZ-T)
For exact electrical specs (isolation rating, gain/bandwidth, input/output ranges, temperature range), consult the ISL3156EIUZ-T datasheet. I can summarize specific figures if you provide the datasheet or needed parameters.
