What are the key features of LM386M-1X?
- Single-channel audio power amplifier with 325 mW output power for battery-powered speaker applications
- Fixed gain of 46 dB with 300 kHz bandwidth enabling clear audio reproduction from low-voltage supplies
- Compact 8-pin SOIC (1.75 mm max height) package for space-constrained PCB designs
What is LM386M-1X used for?
The LM386M-1X is widely used in portable consumer electronics such as radios, intercoms, and battery-powered speakers where a low-voltage, low-component-count audio amplifier is needed. Its single-supply operation and 325 mW output power make it well-suited for driving 8-ohm speakers directly from 5 V to 12 V rails. It also finds application in hobby electronics projects and toy audio circuits requiring minimal external components.

Frequently Asked Questions
How much output power can the LM386M-1X deliver, and at what supply voltage?
The LM386M-1X delivers a nominal output power of 325 mW into an 8-ohm load when operated from a 6 V single supply. It can function across a supply range of approximately 4 V to 12 V, making it practical for battery-powered applications such as portable radios and intercoms.
For a compact battery-powered speaker design, how does the LM386M-1X SOIC package help save board space?
The LM386M-1X comes in an 8-pin SOIC package with a maximum body height of 1.75 mm and a narrow footprint, requiring significantly less PCB area than through-hole DIP alternatives. This compact profile is ideal for handheld consumer devices where board real estate and height clearance are tightly constrained.
When would an engineer select LM386M-1X instead of a higher-power Class D amplifier for a project?
Engineers choose the LM386M-1X when a design requires a simple, low-cost audio amplifier with minimal external components and the 325 mW output power is sufficient for the speaker load. Unlike Class D amplifiers, the LM386 needs no switching filter inductors, reducing BOM complexity and EMI concerns in low-frequency audio applications up to 300 kHz bandwidth.
What harmonic distortion level should designers expect from the LM386M-1X at full output?
The LM386M-1X exhibits a harmonic distortion of approximately 10% at its rated 325 mW output power. This level is acceptable for voice-grade and low-fidelity audio applications such as intercom systems, alarm tones, and toy sound circuits, though it is higher than hi-fi amplifiers with THD below 1%.
