TDA1308T/N1,112

Overview

The TDA1308T/N1,112 is a Class-AB stereo headphone driver fabricated in a 1μm CMOS process. It operates on a single supply voltage of 3.0V to 7.0V or dual supplies of ±1.5V to ±3.5V. The device delivers up to 40mW output power into a 32Ω load with less than 0.1% THD+N. Key electrical parameters include a typical signal-to-noise ratio of 110dB and a channel separation of 70dB at 5kΩ. It functions within an ambient temperature range of -40°C to +85°C.

Feature Summary

• Eliminates switch-on/off clicks during operation
• Provides excellent power supply ripple rejection
• Features short-circuit resistant outputs
• Delivers high performance with low distortion

Applications

• Portable digital audio applications
• CD players
• Discman devices

Procurement Notes

Verify the specific ordering suffix against NXP documentation to confirm package type and revision status. Confirm RoHS compliance and REACH status for current manufacturing batches. Check product lifecycle status as older revisions may be discontinued. Ensure compatibility with existing PCB footprints for SO8 packages before procurement.

Selection Notes

Select this component for portable audio designs requiring low voltage operation and high fidelity. The TDA1308A variant supports lower supply voltages compared to the standard TDA1308. Consider thermal resistance characteristics when designing heat dissipation for dense PCB layouts. Verify input offset voltage requirements for specific noise-sensitive applications.
