TDA7563APD

Overview

The TDA7563APD is a multifunction quad power amplifier designed for automotive applications. It operates within an 8V to 18V supply voltage range and utilizes a PowerSO-36 surface-mount package with 36 pins. The device supports a junction temperature range from -55°C to 150°C. It is classified as a Class AB audio amplifier with a nominal bandwidth of 22 kHz and a gain of 30 dB. The component is RoHS compliant and lead-free, though it is currently marked as obsolete.

Feature Summary

• Multifunction quad power amplifier architecture
• Built-in diagnostic features
• Automotive-grade thermal stability

Applications

• Car radio amplifiers
• Automotive audio systems

Procurement Notes

Verify the obsolete status before procurement planning. Confirm availability through secondary distributors or surplus channels. Ensure compatibility with existing PowerSO-36 footprints. Check for RoHS compliance documentation if required by specific regional regulations. Validate that the 8V to 18V operating range matches the target vehicle's electrical system specifications.

Selection Notes

Select this component for designs requiring a quad bridge configuration in a compact PowerSO-36 package. Consider its Class AB operation and 30 dB gain characteristics for standard automotive audio requirements. Evaluate the -55°C to 150°C junction temperature range against the expected thermal environment. Note that the obsolete status may impact long-term supply chain stability.
