LA4446 Description

Short technical summary and product information.

The Sanyo Denki LA4446 is a monolithic linear integrated circuit designed as a 5.5W, 2-channel AF power amplifier, commonly used in car stereo systems. It offers dual-channel output with a typical power of 5.5W per channel into a 4Ω load at 1kHz.

Key features include low pop noise during power supply transitions, good starting balance, and a ripple rejection of 46dB typical. The device also boasts good channel separation and low residual noise. For enhanced reliability and protection, the LA4446 incorporates on-chip protectors, including a thermal protector, an overvoltage/surge protector, and an adjacent pin short protector.

This amplifier operates within a supply voltage range of 10V to 18V, with a recommended operating voltage of 13.2V. It is housed in a SIP13H through-hole package, requiring appropriate mounting considerations for heat dissipation.

The LA4446 is suitable for applications requiring a robust and efficient audio amplification solution, particularly in automotive environments where space and power efficiency are critical.
