Ordering number : EN4343A Thick Film Hybrid IC STK401-050 AF Power Amplifier (Split Power Supply) (30 W + 30 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 6/3 drive in order to support the low impedance of modern speakers. Package Dimensions unit: mm 4134 [STK401-050] 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 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.
