Based on CMOS technology, the PT2315 is a 2-channel digital control audio processor. This integrated circuit combines volume, bass, treble, and balance control capabilities into a single chip. With the Loudness function and adjustable input gain, you may create a highly effective electronic audio processor with the best performance and dependability while using the fewest external components possible. The I2C bus may be used to programme all functionalities. Meanwhile, the PT2315 IC, which comes in a 28-pin SOIC package, is marketed as a pin-drop replacement for the TDA7315 and has very similar performance.
The pin assignments and application circuit for this volume controller IC have been improved for ease of PCB layout and cost savings. The DATA and CLK pins on this IC are used to send and receive data from the CPU to the PT2315. The BUS Interface’s DATA and CLK functions. The pull-up resistors should be linked to the positive supply voltage as much as possible.
Data Validation
- The data on the DATA line considered stable when the CLK signal is HIGH.
- The HIGH and LOW states of the DATA line changes only when the CLK is LOW.
Start and Stop Condition
A Start Condition is activated when
- The CLK set to HIGH and
- DATA shifts from HIGH to LOW State.
The Stop Condition activated when
- CLK set to HIGH and
- DATA 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.
Applications
- Car Stereo (Audio)
- Hi-Fi Audio System
- Used in all I2C System Applications
