applications. The output current modulation is DC 鈥?/div>
voltage controlled. The modulation current is disabled
when output enable is HIGH.
The device incorporates complementary open collector
outputs with a capability of driving peak current of 75mA.
The laser driver current is adjustable by selection of R
SET
.
The resistor R
EXT
must be placed between OUT and
V
CC
to dissipate the worst case power. R
SER
is
recommended to fix laser diode matching issues.
The SY100EL1003 utilizes the high performance
bipolar ASSET technology.
