LA4145 Description

Short technical summary and product information.

The Sanyo Denki LA4145 is a monolithic linear IC designed as an AF Power Amplifier, particularly suited for applications in cassette tape recorders, radio-cassette players, and stereo cassette players. It operates with a recommended supply voltage of 6V and can deliver up to 0.9W of output power into a 4 Ohm load with 10% THD, or 0.6W into an 8 Ohm load.

 

The device requires a minimum number of external parts, features soft clip functionality, and produces small pop noise during VCC ON/OFF modes. The fixed voltage gain is 50 dB, which can be reduced with an external resistor. The operating voltage range is from 3.6V to 8V, with a maximum supply voltage of 9V in quiescent mode and 8V in operating mode.

 

Packaged in a SIP9 (3017C-SIP9) format, the LA4145 operates within an ambient temperature range of -20°C to +70°C. Its allowable power dissipation is 0.9W with a 50x50mm PCB. Key electrical characteristics include a typical quiescent current of 10mA, a typical input resistance of 30 kΩ, and a typical output noise voltage of 0.6mV.
