LA4445 Description

Short technical summary and product information.

The Sanyo Denki LA4445 is a monolithic linear integrated circuit designed as a 5.5W, 2-channel AF power amplifier. It is housed in a SIP12H package and is suitable for through-hole mounting.

 

Key electrical specifications include a typical output power of 5.5W per channel into a 4Ω load at 13.2V supply voltage. The device exhibits good performance characteristics such as a typical ripple rejection of 46dB and a typical channel separation of 45dB. It operates within a voltage range of 10V to 16V, with a maximum recommended supply voltage of 18V and an absolute maximum supply voltage of 27V. The maximum power dissipation is rated at 15W.

 

For reliability and ease of use, the LA4445 incorporates several built-in protectors, including a thermal protector, an overvoltage/surge protector, and an adjacent pin short protector. It also features small pop noise during power supply transitions and good starting balance.

 

This amplifier is suitable for various audio applications where a compact, dual-channel power output is required. The minimum number of external parts needed simplifies circuit design.
