LA4446
Overview
The LA4446 is a two-channel 5.5W AF power amplifier IC for car stereo systems.
Features
Two 5.5W channels (VCC = 13.2V, RL = 4Ω)
Minimal impulse noise at power supply on/off and excellent starting balance
Excellent ripple rejection ratio : 46dB (typical)
Superlative channel separation
Minimal residual noise : Rg = 0
Full complement of protection circuits
a. Thermal protection circuit, b. Overvoltage protection circuit, c. Shorting to adjacent pin protection circuits (pins 7/8
and 6/7).
