PT2322 6-Channel Audio Processor IC - I2C - Arduino Library - Tone/Volume/Mute

PT2322 6-Channel Audio Processor IC This is an ineresting chip and is very flexible for audio control. It's designed as a 5.1 audio processor enabling you to control your audio setup from your Arduino. Oddwires has the only library written for the Arduino for this device. Download it here: Library and Example. You could use the 6 channels to control an active amplifier using 3 channels for hi/mid/lo over two channels. Very cost-effective if you use any of the chip amps we have on the site. There is also a PCB board for LM1875/TDA2030 amps avilable on the site. You'll find the library and example on the documents page.PT2322 is a 6-Channel Audio Processor IC utilizing CMOS Technology specially designed for audio applications. 6-channel individual input, 6-channel master volume control, 6-channel individual volume trim control, 3-band tone control(treble, middle, and bass), mute function, 3D effect function, tone defeat function are all built into a single chip having the highest performance and reliability with few extenal components. Furthermore, the pin assignments and application circuit are optimized for easy PCB Layout and cost saving benefits. Housed in a 28 pin DIP Package, PT2322 is a great solution for micro-controller audio applications.
