Stereo Circuit Schematic of The ADAU1592 Audio Power Amplifier

Description: This is a stereo circuit schematic of the ADAU1592, a 2-channel, bridge-tied load (BTL) switching audio power amplifier. The ADAU1592 can be utilized in compact television sets, PC audio systems, and mini-component applications. According to the ADAU1592 datasheet, an external protection circuit is recommended for applications that require a supply voltage (PVDD) greater than 15 V. For this purpose, an RC snubber or Schottky diode may be employed. To avoid the unwanted frequencies of asynchronous clocks (especially when using multiple ADAU1592s) within the audio band, it is advisable to use only one clock source if the ADAU1592s share the same power supply. Additionally, a typical configuration can be created using the ADAU1592 by setting pin 11 (MO/ST) to a high state, as detailed in the datasheet.

The ADAU1592 is designed to deliver high-quality audio amplification in a compact form factor, making it suitable for various consumer electronics. It operates as a bridge-tied load amplifier, which allows it to drive speakers directly without the need for a separate output transformer. This configuration enhances efficiency and reduces the overall size of the audio system.

For applications requiring a power supply voltage exceeding 15 V, the incorporation of an external protection circuit is crucial. The recommended RC snubber circuit can effectively dampen voltage spikes and transients that may occur during operation, thereby protecting the amplifier and connected components. Alternatively, a Schottky diode can be implemented to provide a fast recovery path for any reverse currents, further enhancing the reliability of the circuit.

When deploying multiple ADAU1592 amplifiers in a single audio system, careful attention must be paid to clock management. Utilizing a single clock source mitigates the risk of clock skew and the generation of unwanted frequencies that could interfere with audio quality. This approach ensures synchronized operation of the amplifiers, resulting in a cohesive audio output.

The configuration of the ADAU1592 can be tailored to specific application needs by adjusting pin settings. Setting pin 11 (MO/ST) to a high state enables a particular operational mode, allowing for flexibility in the design of the audio system. The detailed characteristics and operational guidelines for this configuration are outlined in the ADAU1592 datasheet, which serves as an essential resource for engineers and designers working with this amplifier.

Overall, the ADAU1592 is a versatile and efficient solution for audio amplification in various applications, providing designers with the tools necessary to create high-performance audio systems.This is a stereo circuit schematic of the ADAU1592, a 2-channel, bridge-tied amount (BTL) switching audio ability amplifier.
