The PAM8610 is a 10W (per channel) stereo Class-D audio amplifier with DC Volume Control which offers low THD+N (0.1%), low EMI, and good PSRR thus high-quality sound reproduction. The 32 steps DC volume control has a +32dB to -75dB range. The PAM8610 runs off of a 7V to 15V supply at much higher efficiency than competitors’ ICs.
The PAM8610 only requires very few external components, significantly saving cost and board space. The PAM8610 is available in a 40pin QFN 6mm*6mm package.
An easy to use module for 10 seconds of voice recording. High-quality, natural voice restored. Can be used as propaganda module. With looping, jog playback, single-pass play function. Single-chip control available. This module can directly drive a small speaker 8 ohm 0.5W.
This low voltage audio power amplifier is ideal if you need a small amplifier for your audio experiments and prototypes. This power packed tiny amplifier circuit can amplify your audio upto 200 times. No soldering is required to connect a speaker with the on board screw terminal connectors. The size is sufficiently small to be fitted in a variety of enclosures like as radio, CD/DVD player etc.
This is a small PCB (printed circuit board) mountable buzzer whose small size makes it perfect for all types of DIY and breadboard projects as well as actual electronics production.
This Buzzer emits really loud sound when 5V to 12V DC is applied to it. Unlike a plain piezo, this buzzer does not need an AC signal. Inside is a piezo plus the driver circuitry that makes it oscillate at 2.3 KHz. On one hand, that makes it really great for integrating into projects because you don’t need an oscillating control signal but on the other hand, you cannot change the frequency.
This MP3 decoder circuit board can play MP3 files from a USB pen drive or from a MicroSD memory card. The player has decent sound quality, an on-board 2W mono amplifier, and can be directly connected to a speaker. It also features a 3.5 mm gold plated headphone jack that can connect headphones or give output to an external sound system or amplifier.
The PAM8403 module is a mini digital 2 x 3 Watt class D power amplifier board, which can also work on USB power supply (5V DC). It is a great tool for DIY hobbyists looking to build a small amplifier, portable speaker or even for replacing the amplifier circuit in your old radio, TV or CD/DVD player.
