LM386

Low-power audio amplifier.

Tutorial / documentation

Analogue circuits

First tests with LM386

  1. Identify the exact LM386 variant, package and manufacturer documentation.
  2. Identify power, ground and signal pins in the documentation. Assemble the circuit with power disconnected.
  3. Follow the manufacturer’s evaluation circuit. Use a current-limited low-voltage supply and the recommended logic levels.
  4. Mesurez les signaux d’entrée et de sortie. Comparez leur comportement à la fonction : amplificateur audio basse puissance.
