APPLICATION CIRCUIT:

A> IO1 -- COUT ; IO2 -- LED ; IO3 -- CONTROL INPUT.

Rosc

VDD

TG

IO2

LED

busy,3Hz,6Hz,or dynamic

S ( 8 ohm SPEAKER )

IO3

GND

IO1

T ( 8050 )

B> IO1 -- LED ; IO2,IO3 --8,32,64 ohm SPEAKER OR BUZZER.

Rosc

VDD

busy,3Hz,6Hz,or dynamic

IO3

S (BUZZER OR 8,32,64 ohm SPEAKER )

C> IO1 -- COUT ; IO2,IO3 -- 8,32,64 ohm SPEAKER OR BUZZER.

Rosc

IO2

GND

IO3

S (BUZZER OR 8,32,64 ohm SPEAKER )

NOTE: 1>Rosc=300K ohm ( Rosc=180K ohm in AMA140A ) ( typical ) , or use internal Rosc ( it must be determined before operation )

Tbata=130( typical )

2>BUZZER:resonant frequency should around 1KHz.

3>Input switch could be replace by CDS.

4>COUT,PWM1,PWM2 are tristate during standby.
