Product details

325 mW into 8 Ω — the classic low-power audio workhorse

The LM386N-1 is a Texas Instruments Class AB audio amplifier delivering 325 mW into an 8 Ω load from a single 4V to 12V supply. That output level suits small battery-powered speakers, headphone drivers, and line-level audio output stages in consumer and hobbyist gear.

4V to 12V supply — flexible rail tolerance

The 4V to 12V supply range means the LM386N-1 operates directly from a single 5V logic rail, a 9V battery, or a 12V unregulated supply without an additional regulator. This simplifies the BOM for portable and low-cost audio designs. The 8-DIP (PDIP-8) footprint is breadboard-friendly and easy to hand-solder, but the through-hole format limits automated assembly throughput compared to surface-mount alternatives.

Frequently asked questions

Can I use LM386N-1 in a 5V circuit?

Yes. The supply range is 4V to 12V, so a 5V rail is well within the operating window. At 5V the output power will be lower than the 325 mW rating at 8 Ω (which is specified at the higher end of the supply range), but the part functions correctly.
