BA5406 /BA5417 is a dual OTL monolithic power supply IC with two built-in high output speaker amplifier circuits. High output When VCC = 12V and RL = 3Ω, it can generate 5W × 2; when VCC = 9V and RL = 3Ω, it can generate 2.8W × 2. The BA5406, which uses a high allowable power dissipation package, has a simple heat sink design. Not only does the BA5417 go beyond basic features, it also has built-in soft clip circuitry, thermal shutdown and standby circuitry. General purpose stereo audio amplifier using the BA5406 monolithic power amplifier IC. Can be used alone or in combination with existing equipment. Components available with 28dB (standard) or 46dB (high) gain. The standard gain option is great for general audio applications, more suitable for most preamps or PC sound cards, etc. Volume control is easily achieved by adding an external dual resistor between 10K ohms and 50K to the audio input. Comes with all components including heatsink. Speakers and cables are not included.

Precautions for use

1) The figures and data in the entry are representative design values and are not guaranteed values for the project.

2) While ROHM is confident that the example application circuit reflects the best recommendations, be sure to verify the circuit characteristics for your specific application. Modifying the constants of other externally connected circuits may cause changes in the static and transient characteristics of the external components as well as the Rohm IC. Allows sufficient margin to determine circuit constants.

3) Absolute Maximum Ratings

Using the IC beyond its absolute maximum ratings, such as the applied voltage or operating temperature range (Topr), may cause damage to the IC. No assumption should be made about the state of the IC (short mode or open mode) that such damage is suffered. Physical safeguards should be implemented when ICs are sometimes used, such as where fuses may exceed their absolute maximum ratings.

4) GND potential

Ensure minimum GND pin potential under all operating conditions. Make sure that no pins are at any voltage below GND at any time, whether it is a transient signal or not.

5) Thermal Design

Thermal design is performed by considering the allowable dissipation (Pd), where there is sufficient margin to actually use the state.

6) Short circuit between terminals and wrong installation

Pay attention to the mounting direction of the IC. Mounting orientation between terminals, GND, or other terminals, or short-circuiting components on the wrong circuit can damage the IC.

7) Operation in strong electromagnetic fields

Using the IC in strong electromagnetic fields can cause malfunctions in operation.
