TDA1517P/N3,112

Overview

The TDA1517P is an integrated Class-B dual output stereo power amplifier designed for multimedia applications. It operates within a supply voltage range of 6.0 V to 18.0 V, delivering up to 6 W of output power into a 4 Ω load at 10% THD. The device features a fixed closed-loop voltage gain of 20 dB and includes a mute/standby switch with low standby current consumption. It incorporates comprehensive protection mechanisms, including thermal shutdown, reverse polarity safety, and short-circuit tolerance to both ground and the positive supply rail.

Feature Summary

• Integrated Class-B dual output amplifier architecture optimized for multimedia audio applications
• Built-in mute and standby switching functionality with minimal quiescent current draw
• Robust protection against thermal overload, reverse polarity connection, and AC/DC output short circuits
• High capability to handle high energy on outputs even when the supply voltage is zero

Applications

• Multimedia audio systems
• Car radio power amplification
• Hi-fi stereo power amplifiers

Procurement Notes

Verify the specific package variant required, as the TDA1517 family includes SIL9MPF, RBS9MPF, and HDIP18 options. Confirm that the application does not require automotive qualification, as this product is explicitly stated as non-automotive qualified. Ensure design safeguards are implemented for any life-critical or safety-critical systems, as the manufacturer accepts no liability for such uses. Check for the most recent datasheet updates before finalizing the design.

Selection Notes

Select the TDA1517P when a simple, high-power stereo amplifier solution with minimal external components is needed. The fixed 20 dB gain simplifies circuit design by removing the need for external feedback resistors for gain setting. Consider the HDIP18 package for superior heat dissipation in enclosed environments due to its lower thermal resistance compared to single-inline variants. Ensure the load impedance matches the 4 Ω specification for optimal power delivery and distortion performance.

Part Context

The TDA1517 series belongs to NXP's portfolio of integrated power amplifiers tailored for consumer electronics and multimedia devices. It serves as a cost-effective alternative to discrete amplifier designs, offering high output power in a compact plastic package. The device complements other audio interface and processing components by providing robust final-stage amplification with built-in protection features suitable for battery-powered and mains-operated systems.

Replacement Considerations

The TDA1517A and TDA1517ATW are listed as similar parts with comparable BTL or SE power amplifier capabilities. Verify pin compatibility and thermal requirements when substituting, as package types may differ. No direct cross-reference is officially confirmed in the provided documentation beyond these similar part numbers.
