Audio-vermogensversterker-IC Texas Instruments LM3886T, eenkanaals, TO-220-11-behuizing

The Texas Instruments LM3886T is a single-channel audio power amplifier IC presented in a TO-220-11 package. It is engineered for use in hi-fi and home audio systems where a discrete output stage is required to drive loudspeakers. The package and pinout are suitable for integration on amplifier PCBs and DIY audio projects that need a reliable, single-channel power amplifier component.

Advantages

The LM3886T offers a compact, thermally manageable TO-220-11 package that facilitates mounting on heatsinks and straightforward PCB layout. Its design provides a stable single output stage with low distortion characteristics appropriate for consumer audio reproduction. The integrated protection features reduce risk from thermal and current overloads, allowing safer operation in varied amplifier designs.

Suitable for

• Single-channel stereo amplifier modules and bridged-mono stages
• DIY audio amplifier projects and hobbyist builds
• Replacement or upgrade of discrete power amplifier stages in home audio equipment
• Small to medium loudspeaker systems in home and studio environments

Key specifications

• Package type: TO-220-11 single-channel power amplifier IC
• Application: audio power amplification for loudspeakers
• Mounting: through-hole package suitable for heatsink attachment
