PT2323 6-Channel Audio Selector IC

The PT2323 is a 6-channel audio selector with CMOS technology built specifically for home theatre systems. It has a built-in 2-Channel to 6-Channel Translator, which combines typical stereo channels to provide a 6-Channel audio output. Furthermore, it has a single 9V power supply, an I2C Bus Interface, and exceptionally low Total Harmonic Distortion (THD 0.005%) built onto a single chip.

As a result, it provides a highly effective electronic audio processor with the best performance and dependability while using the fewest external components possible. The pin assignments and application circuit for this volume controller IC have been improved for ease of PCB layout and cost savings. PT2323 is a 6-channel audio processor IC with 28 pins in a DIP or SO package.

Data is sent to and from the CPU to the PT2323 through the SDA and SCL of this IC. The BUS Interface’s SDA and SCL functions. The pull-up resistors should be linked to the positive supply voltage as much as possible.

Data Validation 

• The data on the SDA line considered stable when the SCL signal is HIGH.
• The HIGH and LOW states of the SDA line change only when the SCL is LOW.

Start and Stop Condition 

A Start Condition is activated when

1.  The SCL set to HIGH and
2. SDA shifts from HIGH to LOW State.

The Stop Condition is activated when

1. SCL set to HIGH and
2. SDA shifts from LOW to HIGH State

To increase and reduce loudness, all audio amplifiers require a mechanism. Mechanical pieces, such as a potentiometer, are used in the majority of such devices. Furthermore, this electrical Volume Controller IC is commonly utilised to produce a digitally controlled audio controller. This is a very basic gadget IC that is used to regulate the audio output from an amplifier electronically.
