DESCRIPTION
The IL388DAA family of Linear Optocoupler consist
of an IRLED optically coupled to two photodiodes.
The emitter is located such that both photodiodes
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 cur-
rent optically by controlling the input photodiode
current.
The IL388DAA is designed to be part of the
DAA2000 kit which consists of one DL207DAA, one
DM207DAA, and two IL388DAAs.
The DL207DAA and DM207DAA ICs provide the
drivers and receivers for the IL388DAA as well as all
other telephone termination functions.
