That’s exactly what’s going on inside an LM386. The schematic, copied from the datasheet, is a simple differential amplifier (the mess of symmetric transistors on the left-hand side) that ...

Instead, he drew up a simple schematic that used an Arduino Nano, an FM radio module based on the TEA5767, and an audio amplifier based on the LM386. A single button on the Arduino helps cycle ...

In circuits 1, 2, and 3, the LM386 inputs are connected directly across the tank circuit and use the LM386 as an RF envelope detector. Circuit 4, with its relatively large value coupling capacitor, ...

The bipolar NE555 timer IC is widely used in inductorless dc-dc converters, most frequently in doubling and inverting converters. However, another very popular IC, the LM386 audio ...
