I
Overview
The AN8725FH is a laser driver IC that can set a laser
emitting level to a maximum precision in recording and
playback of an optical recording equipment such as PD,
and can modulate a laser light in tune with the external
signal.
I
Features
Digital setting of playback current, peak current, bias
current and abnormal light emitting level
Peak current and bias current can be modulated by the
external signal.
Driving current set-up (digital set-up)
For playback: 8-bit
+
4-bit (0 mA to 80 mA)
5-bit
+
4-bit (0 mA to 150 mA)
For peak: 4-bit
+
8-bit (0 mA to 150 mA)
For bias: 4-bit
+
8-bit (0 mA to 150 mA)
Laser output light monitoring circuit built-in
Abnormal light emitting detecting function built-in:
Possible to set up excessive and insufficient light emit-
ting levels with 4-bit DAC for playback and recording,
respectively.
Supply voltage abnormality detection:
Voltage down (3.9 V or less), voltage up (6.1 V or more)
