GPY0033A
PWM AMPLIFIER WITH AUDIO MIXER
1. GENERAL DESCRIPTION
2. FEATURES
The GPY0033A is an audio amplifier, designed especially for
PWM signal. It can accept PWM signal directly without any
external device. In addition, it also provides a channel for analog
signal to mix with the PWM signal; that is, the sound of
microphone is easy to work with the PWM sound. GPY0033A is
also built in the anti-pop circuit to minimize the turn-on and turn-off
pop noise. Normally, it is applied for GPC series, GPF series,
GPL series and other GENERALPLUS products. The GPY0033A
is easily to be used in various applications and products
Wide Operation Range: 2.4V – 5.5V
Bridge-Tied Load (BTL)
Low Distortion: THD+N < 1% (Typ.)
(For VDD = 5.0V, RL = 8.0Ω & Pout = 800mW)
High Output Power: POUT > 0.8W
(For VDD = 5.0V, THD+N =1.0%, f =1.0KHz & RL = 8Ω)
Low Shutdown Current: < 1.0μA
Low Supply Current
Minimize the turn-on and turn-off pop noise
Fast Startup Time
