Is there a 5V audio amplifier for a PC?
USB 5V Audio Amplifier for PC Speakers. Audio amplifiers which are designed to work with a 5 V supply from a USB socket such as from a computer USB are called an USB amplifiers. In this article we will learn how to build a simple 3 watt amplifier circuit which can be powered directly from a computer 5V USB port for driving an 8 ohm 3 watt speaker.
What’s the maximum voltage for a USB speaker?
Maximum supply voltage is 6V, typical working voltage is 5V The minimum and maximum tolerable temperature levels are -65 and 150 degrees Celsius respectively. The input music signal from the USB could be anywhere between -0.3V and 5.3 V Maximum power dissipation is internally limited so no need to worry about this issue.

What’s the rejection ratio for a 5V amplifier?
THD+N indicates the total harmonic distortion which is within 0.13 to 0.25% with a frequency range of 20Hz to 20kHz. PSRR gives us the power supply rejection ratio for Vdd at 5V typical, and this is around 60dB.
What kind of amplifier do I need for multiple TVs?
When you have multiple TV units, it is much advisable to install multi-output versions of the masthead amplifier. As an alternative, you may also opt to use a single-output masthead amplifier and install a splitter to connect to your other TVs.
