Frequently Asked Questions
How many audio channels does the TPA1517NE amplify?
The TPA1517NE is a dual-channel (stereo) audio amplifier, providing two independent amplification channels in a single 20-pin DIP package. Each channel delivers 20dB of gain, making it suitable for driving left and right speakers simultaneously in stereo audio systems.
What is the audio bandwidth and gain of the TPA1517NE?
The TPA1517NE provides a nominal gain of 20dB and a bandwidth of 20kHz, covering the full range of human audible frequencies from 20Hz to 20kHz. This makes it appropriate for music playback and voice amplification in consumer audio products.
What is the THD (Total Harmonic Distortion) of the TPA1517NE?
The TPA1517NE is rated at 10% harmonic distortion, which is typical for Class AB audio amplifiers used in low-cost consumer applications. For applications requiring lower distortion, careful operating point selection and adequate heatsinking can help improve real-world performance.
What package does the TPA1517NE use and is it suitable for breadboard prototyping?
The TPA1517NE uses a 20-pin plastic DIP (Dual-In-Line Package, PDIP-T20) with through-hole leads, which is compatible with standard 0.1-inch pitch breadboards and IC sockets. This makes it highly convenient for rapid prototyping and educational circuit building without the need for soldering.
