Audio Special Purpose
BD37541FS-E2 is a special purpose audio product from ROHM Semiconductor. It is a multi-channel amplifier driver IC, integrated with two differential amplifier channels, two single amplifier channels and two outputs for a PWM signal, suitable for power amplifiers, audio amplifiers and PWM amplifiers. It is capable of driving both low impedance and high impedance loads, supporting wide range of audio device applications.
In terms of application field, BD37541FS-E2 could be used in audio equipment such as digital sound field devices, portable systems, sound playground equipment, car audio systems, music centers and audio stages. Because of its excellent high-accuracy, low-noise and low-power performance, BD37541FS-E2 can be also used in electro-acoustic transducers, digital-to-analog (D/A) converters, microphones, headphones, loudspeakers and electro-acoustics related products.
As for the working principle of BD37541FS-E2, the two differential amplifier channels & two single amplifier channels will work cooperatively, providing higher or lower voltage outputs in order to drive the power amplifiers or audio amplifiers. For instance, when two single amplifier channels are operating, one of them takes the role of an amplifier, while the other acts as an equalizer. Meanwhile, both of the two outputs from wider-range PWM signal are controlled in a very low power consumption condition, which can be used in Class-D power amplifiers, PWM amplifiers and other high power output systems.
Apart from that, BD37541FS-E2 is also equipped with several other advanced functional devices which ensure its excellent sound quality and stability. For example, current sensing ensures the amplifier will keep a certain current even if the load impedance changes, while differential input configuration guarantees the prevention of analog and other noises. In addition, the amplifier-protecting circuit protects devices from overload, overheat or even DC current when it happens, which makes it suitable for various power supplying requirements.
In conclusion, BD37541FS-E2 is a kind of special purpose audio product which serves for multiple audio applications with its high-accuracy, low-noise and low-power performance. With its two differential amplifier channels, two single amplifier channels and two outputs for a PWM signal, especially its advanced functional devices, it is certainly an ideal audio device for various power amplifiers, Class-D power amplifiers, PWM amplifiers and other audio devices.
