Monolithic Linear IC  
For General Audio  
LA4628  
20W 2-Channel BTL Power Amplifier  
Overview  
The LA4628 is a 2-channel general-purpose BTL audio power amplifier provided in a miniature package. It was designed  
for the best possible audio quality and features an extended low band roll-off frequency provided by a newly-developed NF  
circuit that does not require an external capacitor. Furthermore, crosstalk, which can cause muddiness in the audio output,  
has been significantly reduced by both circuit and wiring pattern improvements. Thus this amplifier can provide powerful  
lows and clear highs.  
Note that this device is pin compatible with the 13.5W×2-channel LA4625, and allows end products differentiated by their  
power rating to share the same printed circuit board.  
Features  
• Total output : 20W+20W (at V  
= 13.5V, R = 4Ω, THD = 10%)

• High-fidelity design (f < 10Hz, f = 130kHz)

• Extremely low impulse noise levels  
• An arbitrary amplifier startup time can be set up with external components.  
• Full complement of built-in protection circuits (includes circuits that protect against shorting to V , shorting to ground,

load shorting, overvoltages and excessive temperatures)
