This is the first of two articles on audio circuits. New oper-ational amplifiers from Texas Instruments have excellent audio performance and can be used in high-performance applications. There have been many collections of op amp audio circuits in the past, but all of them focus on split-supply circuits.
LM386 Low Voltage Audio Power Amplifier 1 Features • Battery Operation • Minimum External Parts • Wide Supply Voltage Range: 4 V–12 V or 5 V–18 V • Low Quiescent Current Drain: 4 mA • Voltage Gains from 20 to 200 • Ground-Referenced Input • Self-Centering Output Quiescent Voltage • Low Distortion: 0.2% (AV = 20, VS = 6 V, RL ...
The measurements of a particular audio circuit may vary from the typical specifications. A large variance is usually indicative of a PCB layout or measurement system issue.

This is the third in a series of articles on single-supply audio circuits. The reader is encouraged to review Parts 1 and 2, which appeared in the November 2000 and February 2001 issues, respectively, of Analog Applications Journal. Part 1 concentrated on low-pass and high-pass filters. Part 2 concentrated on audio-notch-filter applications and
• 135W Instantaneous Peak Output Power and hybrid amplifiers by providing an inherently, Capability dynamically protected Safe Operating Area (SOA). • Signal-to-NoiseRatio ≥92dB SPiKe protection means that these parts are completely safeguarded at the output against • An Input Mute Function overvoltage, undervoltage, overloads ...
negative feedback around a high gain DC amplifier would produce a circuit with a precise gain characteristic that depended only on the feedback used. By the proper selection of feedback components, operational amplifier circuits could be used to …
This paper describes the circuit operation of the LM380, its power handling capability, methods of volume and tone con-trol, distortion, and various application circuits such as a bridge amplifier, a power supply splitter, and a high input impedance audio amplifier. CIRCUIT DESCRIPTION Figure 1shows a simplified circuit schematic of the LM380.
