Product details

The Texas Instruments LM386N-4/NOPB is a Class AB audio power amplifier in an 8-pin DIP through-hole package, delivering 1W into a 32Ω load from a single supply rail between 5V and 18V. It is the highest-gain variant in the LM386 family, intended for battery-operated consumer audio, intercoms, portable radios, and simple line-driver stages where a mono speaker or headphone output is needed. The commercial temperature range (0°C to 70°C) suits indoor equipment and benchtop projects, not under-hood or outdoor enclosures.

No end-of-life notice or last-time-buy has been issued. Sourcing is straightforward through independent distribution — we can quote current pricing and availability against an RFQ.

Frequently asked questions

Is LM386N-4/NOPB a direct replacement for LM386N-1?

The LM386N-4/NOPB is pin-compatible with the LM386N-1 and shares the same package and supply range, but it delivers higher output power (1W vs 0.325W into 32Ω). It is a direct drop-in replacement if the load and gain requirements match.

Does LM386N-4/NOPB require external components?

Yes, like all LM386 variants, it requires a few external passive components for proper operation: gain-setting resistors and capacitors, input coupling capacitor, output bypass capacitor, and power supply decoupling. The datasheet application circuit is the reference.

Can LM386N-4/NOPB operate at 5V?

Yes, the supply voltage range is 5V to 18V, so 5V is within the operating range. Output power will be lower than at higher supply voltages — expect roughly 0.3W into 8Ω at 5V.
