DESCRIPTION
The volume controller is a basic function in an audio system, in a modern
multi-channel system always needs a main volume that can adjust volume of all
channels in synchronously. In traditional multi-channel design mostly
utilizing a multi-gang potentiometer, but it’s so expensive and not easy to
achieved well volume attenuation matching between each channel.
Now a better solution is uses the PT2325 to replace the multi-gang
potentiometer. The PT2325 is designed for multi-channel audio purpose, the
chip has 6 groups built-in 48 steps volume attenuator for each channel and
running in synchronous, it only needs an external DC voltage to setting volume
attenuation. In general application, a cheap single-gang potentiometer is work
well to control whole channel’s volume. The DC volume setting also can be
controlled by a PWM signal from the MCU and support 3.3V MCU bus voltage.
The performance of the PT2325 is excellent for the high cost/performance
multi-channel audio system, its wide attenuation range (down to -100dB), high
channel separation characteristics is also suite for other high quality audio
purpose.
