STK401-090

Ordering number : EN4344A Thick Film Hybrid IC STK401-090 AF Power Amplifier (Split Power Supply) (50 W + 50 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 is possible using the same PCB. In addition, this new series of ICs has a 6/3Ω drive in order to support the low impedance of modern speakers. Features Pin-compatible STK400-000 series (3-channel/single package) Package Dimensions unit: mm 4134 [STK401-090] ¥ STK401-000 series (2-channel/single package) Output load impedance RL=6Ω/3Ω supported New pin arrangement 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, boot-strap capacitors and boot-strap resistors for external circuits can be greatly reduced.
