D2025 dual-channel audio amplifier circuit diagram

The D2025 is a dual audio power amplifier circuit designed as a stereo audio power amplifier integrated circuit. It comes in a DIP16 package and is applicable for various portable devices, such as tape recorders or portable stereo systems. It is suitable for dual symmetrical or BTL (Bridge-Tied Load) wide-range supply voltage connections, ranging from 3V to 12V. The maximum voltage gain is 45dB, and the low voltage operation can be adjusted using an external resistor, enabling normal functionality under 3V. The circuit diagram for the D2025 dual-channel audio amplifier is illustrated in the accompanying figure.

The D2025 dual audio power amplifier is engineered to deliver high-quality audio amplification in compact electronic devices. This integrated circuit is particularly advantageous for portable applications due to its low power requirements and versatility in voltage supply. The DIP16 package facilitates easy integration into various circuit designs, allowing for straightforward soldering onto printed circuit boards (PCBs).

The amplifier operates efficiently within a supply voltage range of 3V to 12V, making it suitable for battery-operated devices. The ability to function at lower voltages is critical for portable applications, where power conservation is essential. The external resistor adjustment feature allows designers to fine-tune the amplifier's performance, ensuring optimal operation even at reduced voltages.

With a maximum voltage gain of 45dB, the D2025 provides robust amplification, making it suitable for driving speakers in portable audio systems. The dual symmetrical configuration supports stereo sound output, enhancing the listening experience by providing clear and balanced audio reproduction.

The BTL connection mode is particularly noteworthy, as it enables the amplifier to drive a load with higher efficiency by utilizing both outputs of the amplifier. This configuration can lead to improved sound quality and power output, making it ideal for applications where space is limited, and performance is paramount.

In summary, the D2025 dual audio power amplifier circuit is a versatile and efficient solution for enhancing audio performance in portable devices, with features that cater to modern design requirements in the electronics industry.D2025 Dual audio power amplifier circuit D2025 is a stereo audio power amplifier integrated circuits, power amplifier for use DIP16 package applicable to all types of portable tape recorders or portable stereo.
