Ordering number: EN 4679A Thick Film Hybrid IC STK401-040 AF Power Amplifier (Split Power Supply) (25W+25W min, THD = 0.4%) Overview Package Dimensions The STK401-040 is a thick-film audio power amplifier IC belonging to a series in which all devices are pin compatible. This allows a single PCB design to be used to construct amplifiers of various output capacity simply by changing hybrid ICs. Also, this series is part of a new, larger series that comprises mutually similar devices with the same pin compatibility. This makes possible the development of a 2-channel amplifier from a 3-channel amplifier using the same PCB. In addition, this new series features 6/3Ω drive in order to support the low impedance of modern speakers.
