PT2325

6 Channel Volume Control

DESCRIPTION

FEATURES

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.

•

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

channel

Operating voltage range:

- Volume buffer : 5 ~ 10V

- Volume controller: 3.3 ~ 10V

Low noise, High SNR: Greater than 100dB

(A-Weighted)

•

High channel separation > 100dB

Built-in MUTE function

DC controlled volume attenuation

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.

APPLICATIONS

•

AV surround system

Mini combo

PC multimedia speaker

Other audio applications
