TDA1517/N3,112

Overview

The TDA1517/N3,112 is a stereo power amplifier manufactured by NXP Semiconductors. It operates on a supply voltage (VP) ranging from 6.0 V to 18.0 V with a typical value of 14.4 V. The device delivers an output power of 5 W at 4 Ω load with 0.5% THD, and up to 6 W at 10% THD. Key electrical parameters include a closed-loop voltage gain of 20 dB, total quiescent current of 40 mA, and standby current under 100 μA. It features a repetitive peak output current of 2.5 A and input impedance of 50 kΩ.

Feature Summary

• Integrated class-B dual output amplifier designed for multimedia applications
• Mute/standby switch functionality with low standby current consumption
• Protection mechanisms including AC/DC short-circuit safety, thermal protection, and reverse polarity safety
• Fixed voltage gain with high ripple rejection capabilities

Applications

• Multimedia audio systems
• Stereo power amplification circuits
• Low-voltage audio playback devices

Procurement Notes

Verify the specific package variant required, as the TDA1517/N3 corresponds to the SIL9MPF plastic single in-line medium power package with fin (SOT110-1). Confirm compatibility with through-hole mounting methods such as wave or dip soldering. Ensure design safeguards are in place for operating conditions within the specified absolute maximum ratings to prevent permanent damage.

Selection Notes

Select this component for applications requiring a fixed-gain stereo amplifier with minimal external components. The device supports supply voltages between 6 V and 18 V. Consider the thermal resistance characteristics when designing heat dissipation strategies. Verify that the required output power aligns with the 4 Ω load specifications provided in the datasheet.
