TPA1517NE application field and working principle

The TPA1517NE is a low-power audio amplifier primarily intended for use in portable and residential audio devices such as phones, mp3 players, and television sets. It is capable of driving 1.5 A of peak current output and fuses a low-noise preamplifier and a high-efficiency Class-D output stage into a single, compact device. Thanks to its high efficiency, the TPA1517NE has a very low heat dissipation and can be configured to operate from a single supply, instead of the usual dual-supply topology.

Application field

The TPA1517NE audio amplifier integrates a low-noise pre-amplifier and a high-efficiency Class-D output stage into one very compact package, making it ideal for applications where space is limited. It is suitable for uses both in portable and residential audio products, such as phones, music players, and televisions. Furthermore, its single-supply configuration makes it all the more flexible and can be used to power various music and sound systems.

Working Principle

At the heart of the TPA1517NE audio amplifier is a low-noise pre-amplifier with band-gap reference. This amplifies the input signal and provides an output that can be further amplified and switched on and off using the integrated N-channel MOSFETs. In this way, the amplifier can achieve a very low-noise output with high efficiency.

The amplifier also comes with a resonance free output and adjustable gain, allowing it to noticeably improve the performance of audio systems in both low- and high-frequency ranges. Furthermore, its integrated protection circuit helps protect it against short circuits, thermal and overload conditions.

Conclusion

The TPA1517NE is a low-power, low-cost audio amplifier intended for use in portable and residential audio devices such as phones, mp3 players, and television sets. Its single-supply configuration, low-noise pre-amplifier, high-efficiency Class-D output stage and integrated protection circuit make it a perfect choice for many audio applications. Thanks to its high efficiency and low heat dissipation, the TPA1517NE can provide a great performance with minimum power consumption.
