Function
S9684 series photo IC integrates a photodiode chip and an IC chip into the same package. The photodiode chip is internally
connected to the IC chip as shown in the block diagram. S9684 series should be used with terminals Ro1 and Ro2 connected to
an external gain resistance.
Two photocurrents are generated when a laser beam enters the dual-element photodiode. Each photocurrent is fed to the input
terminal of the IC and, after being amplified by the current amplifier, flows to the external gain resistance. At this time, voltages
V
RO1
and V
RO2
at terminals Ro1 and Ro2 are given by the following expression.
V
RO1
(V
RO2
)=A × S × PI × Ro1 (Ro2) [V]
A: Current amplifier gain (S9684: 20 times, S9684-01: 6 times)
S: Photodiode sensitivity [A/W] (approx. 0.45 A/W at 780 nm)
P
I
: Input power [W]
Ro1, Ro2: External gain resistance [
]; usable range 2 k
to 10 k
V
RO1
and V
RO2
are input to the internal comparator so the output Vo is “High” when V
RO1
> V
RO2
or “Low” when V
RO1
< V
RO2
.
We recommend using S9684 series under the operating conditions that V
RO1
and V
RO2
are 2 to 3 V.
