What are the key features of TPA1517NEG4?
- Stereo 6 W per channel output power driving 4-ohm or 8-ohm speakers from a single 5 V to 8 V supply
- Integrated thermal shutdown and short-circuit protection reducing the need for external protection components in consumer audio designs
- 20-pin DIP package enabling breadboard prototyping and easy integration into battery-powered portable audio systems
What is TPA1517NEG4 used for?
The TPA1517NEG4 is suited for portable speaker systems, desktop multimedia speakers, and battery-powered audio applications requiring 6 W per channel stereo output from a compact IC. It is commonly used in educational electronics kits, AM/FM radio designs, and small home audio devices where a simple, low-component-count amplifier solution is needed. The through-hole DIP package simplifies assembly in low-volume production and classroom prototyping scenarios.

Frequently Asked Questions
What supply voltage range does the TPA1517NEG4 support, and how does this affect loudspeaker power output?
The TPA1517NEG4 operates from a supply voltage range of approximately 4 V to 8 V. At 5 V with a 4-ohm speaker load, it delivers up to 6 W per channel stereo audio output, while at higher supply voltages closer to 8 V the output power increases further, making it versatile for USB-powered (5 V) as well as alkaline battery pack (6 V) applications.
How do the built-in thermal shutdown and short-circuit protection features of the TPA1517NEG4 reduce BOM complexity?
The integrated thermal shutdown activates when the die temperature exceeds approximately 150°C, protecting the device without requiring an external thermistor or protection circuit. Short-circuit protection limits output current during fault conditions on the speaker terminals, eliminating the need for external fuses or current-sense resistors and reducing the bill of materials by at least 2 to 4 passive components.
For a classroom or hobbyist audio project, how quickly can the TPA1517NEG4 DIP package be evaluated on a breadboard?
The 20-pin DIP package with 2.54 mm pin pitch fits directly into a standard breadboard. A basic evaluation circuit requires a power supply of 5 V to 8 V, two 0.1 µF bypass capacitors, two 1 µF input coupling capacitors, and 4-ohm or 8-ohm speakers, enabling a working stereo amplifier prototype to be built in under 30 minutes without any soldering.
How does the TPA1517NEG4 compare to the TPA1517 for procurement when the bridged load output configuration is needed?
The TPA1517NEG4 is the tape-and-reel packaged variant of the TPA1517 family in a 20-pin DIP, suitable for automated pick-and-place assembly in moderate volumes. Both variants share the same 6 W per channel stereo specifications and 4-ohm minimum speaker impedance. Designers requiring bridged-mode (BTL) output for higher power levels may consider the TPA1516 or TPA1519 variants, which are optimized for 8-ohm bridged speaker loads.
