Description The basic parameters of the amplifier: Maximum voltage + - 42V 60mA Quiescent current about Continuous output power (power + - 30V, Rload 4 ohm) 68W nonlinear distortion (P = 60W) 0.03%. Used for the construction of a modern amplifier chip LM3886 from National Semiconductor. This amplifier is equipped with thermal protection, short circuit and system switching noise mute on and off. The use of a symmetrical value eliminates the need for the output capacitor.
