Features, Applications

AF Power Amplifier (Split Power Supply) + 50W min, THD = 0.08%)

Now, thick-film audio power amplifier ICs are available with pin-compatibility to permit a single PCB to be designed and amplifier output capacity changed simply by installing a hybrid IC. This new series was developed with this kind of pin-compatibility to ensure integration between systems everywhere. With this new series of ICs, even changes from 3-channel amplifier to 2-channel amplifiers is possible using the same PCB. In addition, this new series of ICs has a 6/3 drive in order to support the low impedance of modern speakers.

Features

Pin-compatible STK400-000 series (3-channel, single package) STK401-000 series (2-channel, single package) Output load impedance RL=6/3 supported New pin assignment To simplify input/output pattern layout and minimize the effects of pattern layout on operational characteristics, pin assignments are grouped into blocks consisting of input, output and power systems. Few external circuits Compared to those series used until now, capacitors and bootstrap resistors for external circuits can be greatly reduced.

Notes Use rated power supply for testing unless otherwise specified. When measuring available time for load short-circuit and output noise voltage, use transformer power supply indicated below. Output noise voltage is represented by the peak value rms (VTVM) for mean reading. Use an AC stabilized power supply (50 Hz) on the primary side to eliminate the effect of AC flicker noise.
