6 Channel Volume Control

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.

FEATURES

• 6 channels, volume control range 0 ~ -100dB/per channel

• Operating voltage range: 5 ~ 10V (Volume Buffer)

3.3 ~ 10V (Volume Controller)

• Low noise, High SNR: Greater than 100dB (A-Weighted)

• High channel separation > 100dB

• Built-in MUTE function

• DC controlled volume attenuation

APPLICATIONS

• AV surround system

• Car audio

• Mini combo

• PC multimedia speaker

• Other audio applications
