Application example
The response time (attack and release time) can be
changed by varying the values of C
1
and R
1
to change the
time constant.
C

is a coupling capacitor, and the potentiometer VR va-
ries the input level. Input a fixed voltage level and adjust
the potentiometer so that the LED lights at 0dB.
To reduce the LED current, connect a resistor either in
parallel (Fig. 3 (1)) or in series (Fig. 3 (2)) with the LED.
If a resistor is connected in series with the LED, the LED
current will change if the supply voltage fluctuates.
Note: If the power supply voltage exceeds 9V, insert a resistor in series with
the LED current supply line, or connect a heat sink so that the maxi-
mum power dissipation Pd Max. is not exceeded (see Fig. 4).
