Overview
The TPA1517DWPR is a stereo audio power amplifier produced by Texas Instruments. It contains two identical amplifiers capable of delivering 6 W per channel of continuous average power into a 4-Ω load at 10% THD+N or 5 W per channel at 1% THD+N. The amplifier features a fixed gain of 20 dB and includes a mute/standby function for power-sensitive applications. It is available in the PowerPAD 20-pin surface-mount thermally-enhanced package (DWP) and the 20-pin thermally enhanced DIP package (NE), both of which offer exceptional thermal characteristics and facilitate automated assembly.
