Audio Special Purpose is now focusing on BD3490FV-E2 which is used for applications involving sound control, such as recording, amplifier control, mixer control, and more. This semiconductor is designed to be incorporated into audio equipment, meeting the requirements for optimal sound quality and precision control.

BD3490FV-E2 is a voltage-controlled amplifier (VCA) that is commonly used to achieve fine-grained control over level adjustment, tone adjustment, equalization, and more. A VCA uses an input signal as a control source to regulate the voltage level of an audio signal. This amplifier offers an optimal ±0.6dB gain accuracy, low noise, and low distortion, making it suitable for a wide range of applications.

The BD3490FV-E2 utilizes a differential amplifier as its core circuit for superior noise and distortion characteristics. This amplifier has a gain-bandwidth product (GBW) of 320MHz, allowing it to achieve high-speed response and low-power consumption. This feature makes this high-performance audio circuit suitable for applications such as active noise control, equalization, and reverberation.

In addition, the BD3490FV-E2 includes a variety of built-in functions such as an analog mute circuit, thermal shut down, OVP (Over Voltage Protection) circuit, and AGC (Automatic Gain Control) circuit. The AGC circuit allows the amplifier to automatically adjust the gain to keep the output signal within a certain level, providing optimal sound quality at all volume levels.

The BD3490FV-E2 is designed to meet the requirements of the latest audio equipment, providing superior sound quality and precision control. It is a versatile semiconductor chip suited for applications requiring sound control, such as recording, amplifier control, mixer control, and more.
