H11F1 [TT Electronics]

The H11F series is a photo FET optocoupler that integrates a GaAlAs IRED with a symmetrical bilateral silicon photodetector. It functions as an ideal isolated FET for distortion-free control of low-level AC and DC analog signals. Key features include remote variable resistor capability (100Ω to 300 MΩ with ≥99.9% linearity), analog switch functionality with extremely low offset voltage and 60V signal capability, no charge injection or latch-up, and fast switching times (≤15 µS). The devices are mounted in dual in-line packages and are UL and VDE recognized.
