Technical Data (continued)
4. Internal circuit of APCPD
(pin 63)
A current mirror circuit of which primary side is APCPD
is built-in. In case where output of secondary side is
connected to APCPD
+
and PD current for laser monitor is sunk to PD, the direction of current can be reversed by
connecting the PD output to APCPD
.
Mirror ratio is 1 to 1 as the h
FE
=
∞
When using no current mirror, connect APCPD
to V
