The Sanyo Denki LA4182 is a versatile 2-channel AF power amplifier IC suitable for stereo and bridge amplifier configurations. It offers a high output power of 2.3 W per channel when operating into a 4-ohm load at a 9V supply voltage, and can deliver 4.7W in bridge mode into an 8-ohm load.
Key features include a built-in muting circuit to minimize pop noise during power supply transitions, and a ripple filter for improved performance. The device operates with a recommended supply voltage of 9V and has a wide operating temperature range from -20°C to +75°C. The LA4182 is housed in a DIP12F package and requires a minimum of 9 external components for stereo or bridge operation.
Designed for ease of integration, the LA4182 simplifies thermal management with an easily designed radiator fin. Its voltage gain is fixed at 45 dB for stereo mode and 51 dB for bridge mode, with options for variable gain. This amplifier is well-suited for various audio applications where compact size and reliable performance are essential.
