DDS原理（e文版） — levension’s Sky. All About Direct Digital Synthesis What is Direct Digital Synthesis? Direct digital synthesis (DDS) is a method of producing an analog waveform—usually a sine wave—by generating a time-varying signal in digital form and then performing a digital-to-analog conversion. Because operations within a DDS device are primarily digital, it can offer fast [...]

LM386 Schematic diagrams »

LM386 Schematic diagrams. Audio Power Amplifiers with LM386 The LM386 is a versatile, small power amplifier designed for use in low voltage consumer applications. The gain is internally set to 20 to keep external part count low, but with the addition of an external resistor and capacitor between pins 1-8 the gain can be set [...]
