Sample Application Circuit 2

LA2000M

Use a mechanism for the plunger off while

functioning for program selection

Unit (resistance: Ω, capacitance: F)

1. Externally connected components

C1

C2

C3, R1

C4, R3

R2

Input coupling capacitor

NF capacitor

For designation of time delays

Power supply ripple filter

Bias resistor

0.47 to 2.2 µF recommended.

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

frequency range. We recommend 1 to 10 µF.

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

150 kΩ to 500 kΩ for R1.

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

recommended.
