• Eliminates switch-on/off clicks during operation
• Provides excellent power supply ripple rejection
• Features high signal-to-noise ratio and low distortion
• Includes integrated short-circuit resistance

Applications

• Portable digital audio applications
• Discman devices
• Optical drive headphone circuits

Procurement Notes

Verify the specific ordering suffix N2,115 against the manufacturer's current product status, as availability may vary. Confirm that the SO8 package dimensions match the SOT96-1 outline specified in the datasheet. Ensure compliance with RoHS3 standards and check for any lead-free soldering requirements relevant to the manufacturing process.

Selection Notes

Select this component for designs requiring low-voltage operation and high performance in portable audio systems. The TDA1308A variant specifically supports lower supply voltages compared to the standard TDA1308. Consider the thermal resistance characteristics of the SO8 package when designing for maximum power dissipation scenarios within the specified ambient temperature limits.
