High performance amplifier CD Walkman -TDA1308

The TDA1308 is a Class AB headphone driver integrated circuit (IC) recently launched by Philips. Its primary features include a compact size and low power consumption, making it particularly suitable for portable CD players and other digital audio devices. The TDA1308 is designed with a small pin package, and its pin functions are detailed in the accompanying documentation. This IC is equipped with short circuit protection and features a sound switch that does not produce any impact noise. It operates within a voltage range of 3 to 7V, with a unity gain and a conversion rate of 5V/μs. The output power is rated at 60mW, with a signal-to-noise ratio (SNR) of 110dB and channel separation of 70dB. An application circuit for the TDA1308 is also provided in the documentation. Audiophiles can utilize this circuit diagram to replace the conventional VCD player, where the TDA1308 serves as a class-level headphone amplification circuit section, yielding satisfactory results.

The TDA1308 integrated circuit is designed for efficient audio amplification in portable devices, specifically targeting applications where size and power efficiency are paramount. The Class AB configuration allows the TDA1308 to deliver high-quality audio output while minimizing power consumption, which is essential for battery-operated devices. The IC's low quiescent current ensures that it does not drain the battery excessively during idle periods.

The pinout of the TDA1308 is optimized for easy integration into existing designs, allowing engineers to implement it in various audio applications without significant redesign. The short circuit protection feature safeguards the device against potential damage from unintended electrical conditions, enhancing the reliability of the circuit in portable applications.

With an output power of 60mW, the TDA1308 is capable of driving headphones with varying impedance levels, making it suitable for a wide range of audio devices. The impressive signal-to-noise ratio of 110dB indicates that the IC can produce clear audio with minimal background noise, which is critical for high-fidelity sound reproduction. The channel separation of 70dB further ensures that the left and right audio channels remain distinct, providing an immersive listening experience.

The application circuit provided in the documentation illustrates how the TDA1308 can be effectively incorporated into audio systems, including those that replace traditional VCD players. By utilizing the TDA1308 in the headphone amplification section, designers can achieve superior audio performance compared to standard integrated circuits like the 4558. This makes the TDA1308 an attractive option for audio enthusiasts looking to enhance their listening experience with portable audio devices.TDA1308 is class AB headphone driver IC Philips recently launched its biggest feature is the small size, low power consumption, is particularly suitable for portable CD players and other digital audio Xin also be used for CD player headphones listening o TDA1308 adopted by pin small package, the pin function as shown in Figure 5-1 perish TDA1308 equipped with short circuit protection, no impact sound switch, operating voltage 3 ~ 7V, unity gain at the conversion rate of 5V / us.U a sv, foot, -32CI, output power 60mW.
