Overview:

D8227 is a dual-channel audio power amplifier integrated circuit, built-in temperature overheat protection circuit, power adjustment switch. Suitable for audio power amplification on portable radio recorder.

 

Large output power POUT=2.5W/CH(typical) (Vcc=9V,RL=4Ω , f = 1 KHZ, THD POUT = 10%) = 3.0 W/CH (typical) (Vcc = 9 v, RL = 3 & Omega; ,f=1kHz,THD=10%)

● Voltage gain: Gv=45dB(typical) (Rf=120Ω ,f=1kHz) Gv=56.5dB(typical) (Rf=0Ω ,f=1kHz)

Low static current; ICCQ=21mA(typical) (Vcc=9V,VIN=0)

● Ripple rejection ratio: R.R.=-52dB(typical)(Vcc=9V, fripple=100Hz, Rg=600&Omega)

Channel isolation: C.T.= -50dB(typical)(Vcc=9V, f=1kHz, Rg=600Ω)

● Output noise voltage: Vno=0.3mVrms (typical)(Vcc=9V, Rg=10kΩ BW=20Hz~20kHz)

● Soft embedding

●  Built-in thermal protection circuit

● Optimal power supply voltage 9V

● Working power supply voltage range: Vcc=5~12V (Ta=25℃)

● Standby switch

Low noise
