This circuit adopts a 9-pin single in-line package and has the advantages of
wide operating power supply voltage range, high gain,
high output power, and low distortion. There are two identical
amplifiers in the circuit, which have
multiple protection functions such as load open circuit, AC and DC short circuit to ground, overheating, etc., and have
functions such as squelch control and power wait state. When working in two channels
, only 4 external components are needed . When working in BTL,
only 1 external component is needed. It is currently one of the power amplifier circuits with the fewest external
components
among similar ICs.
The main electrical parameters of this circuit are: the operating power supply
voltage range is 6~18Vo when Vc=14.4V,
the quiescent current is IQ=40mAo, the voltage gain Gy=40dB
(dual channel) or 46dB (BTL) o harmonic Wave distortion
∞=0.1% (when Po=IW) channel separation
SeP >40dB. The output
power of each channel is Po=1-1W (RL=2fl, 7HD=10%) or 5.5W (RL=4S1, order ∞-10%) when working in two channels.
The output power Po=22W when working in BTL ( RL=4,fl,THD—10%)0
The application circuit is shown in Figure 2-70. Because this circuit has excellent performance and simple peripheral circuits, using it to install the complete machine can greatly
reduce production costs.
