Descriptionshows the X9314 with the low voltage LM386 power amplifier. This AN49.0 circuit will produce 250mW of audio power with only a 5V DC source. Figure 2 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. Eithe...

shows the X9314 with the low voltage LM386 power amplifier. This AN49.0 circuit will produce 250mW of audio power with only a 5V DC source. Figure 2 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. Either AN49.0 will provide plenty of sound for intercom, communications, or monitoring applications. The 1W circuit would be preferred when higher ambient noise is present, such as in an automobile.
