Monolithic Linear IC
LA4276
3 W 2-Channel Power Amplifier
Overview
The LA4276 is a 3 W 2-channel power amplifier intended
for televisions.
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 LA4266 (3 W)/LA4267 (5 W)/
4268 (10 W) and the LA4277 (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 × 2(VCC = 16 V/RL = 8 Ω).
