AN49.0, Application Note for Digital Audio Amplifier Gain Control using Logarithmic Digitally Controlled Potentiometers (XDCPs)

AN49.0, Application Note for Digital Audio Amplifier Gain Control using Logarithmic Digitally Controlled Potentiometers (XDCPs). The X9314 with the low voltage LM386 power amplifier. This circuit will produce 250mW of audio power with only a 5V DC source. It is a similar circuit that uses the higher power LM380 and is capable of delivering over 1W of audio if a 12V DC source is available
