The LM386 is a low voltage audio power amplifier designed for use in low volt- age consumer applications
The LM386 is a low‑voltage audio power amplifier designed for battery‑operated consumer devices. It features an internally set gain of 20, which can be increased to 200 with an external resistor and capacitor between pins 1 and 8, and it operates from a wide supply range of 4 V to 12 V (or 5 V–18 V for some versions). The device offers low quiescent current (4 mA typical) and low distortion (0.2 % THD at 1 kHz).
The datasheet lists absolute maximum ratings, electrical characteristics, typical performance graphs, and recommended application circuits such as AM radio amplifiers, tape‑player drivers, and ultrasonic drivers. Physical dimensions for the dual‑in‑line, molded‑mini, and small‑outline packages are also provided, along with a life‑support policy disclaimer.
