Description
The IL388DAA 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 photocur-
rent. The ratio of the photocurrent stays constant with
high accuracy when either the LED current or the
ambient temperature changes. Thus one can control
the output diode current 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 driv-
ers and receivers for the IL388DAA as well as all
other telephone termination functions.

amb
= 25 擄C, unless otherwise specified
Stresses in excess of the absolute Maximum Ratings can cause permanent damage to the device. Functional operation of the device is
not implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
Maximum Rating for extended periods of the time can adversely affect reliability.
