OPTOELECTRONIC PRODUCTS
DIVISION
10/17/02 Rev B
Features:
Vin (volts) =Iout (mA)
Vin/Iout is constant within 4.0% over temperature
Minimum component count for high reliability
Rugged package (TO-5 )
Internal amplifier for regulation
Rugged output transistor
Applications:
Eliminate ground loops
Level shifting of signals
Line receiver
Power supply feedback loops
Motor control
Signal Isolation
DESCRIPTION
A Gallium Aluminum Arsenide (GaAlAs) infrared LED controlled by a high gain op amp illuminates two matched
phototransistors, one of which provides feedback to the op amp allowing a consistent output from the other. The regulation
provides protection against output signal degradation normally associated with time, temperature and even radiation. The
66229 can be tested to customer specifications, as well as to MIL-PRF-19500 JAN, JANTX, JANTXV and JANS quality levels.
CTR degradation worries are gone when you use the 66229.
