PT2325
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.
