LA4225 Description

Short technical summary and product information.

The LA4225 from Sanyo Denki is a 5W monaural power amplifier IC specifically designed for television audio output stages. This integrated circuit simplifies designs by requiring only two external capacitors to construct a functional amplifier, contributing to significant cost reductions in electronic devices.

Key electrical characteristics include a recommended supply voltage of 13.2V and a recommended load resistance of 4 ohms, with an allowable operating voltage range of 5V to 22V. The device offers an output power of 5W at 18V supply and 8-ohm load, or 4.5W at 13.2V supply and 4-ohm load, both at 10% THD. It features a typical quiescent current of 65mA and a voltage gain of 45dB.

For enhanced reliability, the LA4225 incorporates a full complement of protection circuits, including thermal shutdown and short-circuit protection. It also includes an on-chip pop noise reduction circuit. The component is housed in a SIP5H package suitable for through-hole mounting.

This amplifier is ideal for cost-sensitive audio applications where a single-channel, moderate power output is required, such as in consumer televisions and similar audio systems.
