DESCRIPTION
The IL350, IL351, IL358 family of linear optocoupler consist
of an IRLED optically coupled to two photodiodes. The
emitter mechanically faces both diodes enabling them to
receive approximately an equal amount of infrared light. The
diodes produce a proportional amount of photocurrents.
The ratio of the photocurrents stays constant with high
accuracy when either the LED current changes or the
ambient temperature changes. Thus one can control the
output diode current optically by controlling the input
photodiode current.
The IL350, IL351, IL358 optocouplers can be used with the
aid of operational amplifiers in closed loop conditions to
achieve highly linear and electrically isolated AC and or DC
signal amplifiers.
APPLICATIONS
• Optical DAA for V.34 FAX/modem PCMCIA cards
• Digital telephone line isolation
AGENCY APPROVALS
• UL file no. E52744 system code S
• cUL tested to CSA 22.2 bulletin 5A
