Monolithic Linear IC
LA4266
3 W Monaural Power Amplifier
Overview
The LA4266 is a 3W power amplifier intended for televi-
sions.
This IC has a series of pin compatible monaural and 2-
channel power amplifiers, thus allows the end product to
use a common circuit boad.
Features
• Television audio output.
• Pin compatible with the LA4267 (5 W)/4268 (10 W) and
the LA4276 (3 W × 2)/4277 (5 W × 2)/4278(10 W× 2).
• Package: SIP-10HD (2.54 mm pitch, straight pins).
• Thermal protection circuit and overvoltage protection
circuit on chip.
• Output power: 3 W (VCC = 16 V/RL = 8 ).
