PINOUTS:-

P2                               P1

1 0V                            8 VO+ (to speaker+)

2 SD                           7 0V (supply return)

3 mode                       6 +Vcc (+5V supply)

4 IN                             5 VO- (to speaker-)

(P2 pin 1 has a square pad)

(the SD (shutdown) P2 pin2 has a pull-down resistor…..drive it high 3 to 5V to enable the device)

(the mode pin P2 pin3 selects class AB when low (0V) and class D when high (+2 to +5V))

Example…..unit drew 0.8 amps with +5V supply, pin 3=0V, pin2=+5V and an input sine wave

signal of 1.5KHz @212mV Z=50 ohms
