NTE3085
Optoisolator Photon Coupled Bilateral Analog FET

Description:
The NTE3085 consists of a gallium arsenide infrared emitting diode coupled to a symmetrical silicon photo detector. The detector is electrically isolated from the input and performs like an ideal isolated FET designed for distortion-free control of low AC and DC analog signals.

Features:
As A Remote Variable Resistor
- ≤ 100Ω to ≥ 300MΩ
- ≥ 99.9% Linearity
- ≤ 15pF Shunt Capacitance
- ≥ 100GΩ I/O Isolation Resistance

As An Analog Signal Switch
- Extremely Low Offset Voltage
- 60VP-P Signal Capability
- No Charge Injection or Latchup
- ton, toff ≤ 15μs
