Overview
The LA4485 is a 5 W, two-channel power amplifier IC that requires a minimum of external parts, making it ideal for radio cassette players and car stereo equipment.
The LA4485 eliminates the need for bootstrap capacitors, negative feedback capacitors, and oscillation prevention CR parts, all of which were necessities for power ICs previously. All of these functions are now on chip, keeping the number of external parts to an absolute minimum. The LA4485 is part of the Power (Stylish Power) Series, and supports two modes: dual and BTL.

Features
• 5 W × 2 output power in dual mode, and 15 W in BTL mode
• Minimum external parts for the Power Series count: 4 or 5 parts in dual mode; 3 or 4 parts in BTL mode
• Protection circuits Overvoltage protection Thermal protection DC output short-circuit protection (to VCC and to GND)
• Circuitry designed to handle +VCC applied to the outputs
• Pop noise reduction
• Standby switch
• Muting function
