PT2325 - 6 Channel Volume Controller

General 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.

Key Features

  • 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 Tel: 886-66296288‧Fax: 886-29174598‧ http://www. princeton. com. tw‧2F, 233-1, Baociao Road, Sindian, Taipei 23145, Taiwan.

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.
