The HIIF series are optically coupled isolators consisting of an infrared light emitting diode and a symmetrical bilateral silicon photodetector. They are designed for distortion-free control of low-level ac and dc analog signals.
Features
The HIIF series offer extremely low offset voltage, 60V pk-pk signal capability, no charge injection or latchup, and a high isolation resistance of 2100GΩ.
Applications
The HIIF series are suitable for use as an analog signal switch, isolated sample and hold circuit, multiplexed, optically isolated A/D conversion, and as a remote variable resistor.
They are also used in active filter fine tuning, band switching, and breakdown voltage applications.
