Sample Application Circuit 2

1.

Externally connected components

C1

Input coupling capacitor

0.47 to 2.2 µF recommended.

C2

NF capacitor

Capacitance is reduced, so the off level in input equivalent becomes lower in the bass

frequency range. We recommend 1 to 10 µF.

C3, R1

For designation of time delays

Any time delay can be obtained by adequate choice of C3 and R1. We recommend

150 k

Ω to 500 kΩ for R1.

C4, R3

Power supply ripple filter

R2

Bias resistor

For diode when pin 7 is used to drive external transistors. A 1 k

Ω resistor is

recommended.

Use a mechanism for the plunger off while

functioning for program selection
