STK400-020

Ordering number : EN4830A Thick Film Hybrid IC STK400-020 3-Channel AF Power Amplifier (Split Power Supply) (15 W + 15 W +15 W min, THD = 0.4 %) Overview 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 IC, even changes from 3-channel amplifier to 2-channel amplifiers are possible using the same PCB. In addition, this new series of ICs has a 6/3 Ω drive in order to support the low impedance of modern speakers. Package Dimensions unit : mm 4086A [STK400-020] Features Pin-compatible STK400-000 series (3-channel, single package) STK401-000 series (2-channel, single package) Output load impedance RL=6 Ω/3 Ω 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. ¥ Specifications Maximum Ratings at Ta = 25°C Parameter Maximum supply voltage Thermal resistance Junction temperature Operating substrate temperature Storage temperature range Permissible load short time Symbol VCC max ...
