PT2313, with the ingenious application of CMOS technology, has become an excellent four-channel digital audio processor. It combines compact design with powerful features in a small package. Right/left bass and treble balance, pre/rear fader processor, these multiple audio processing tasks are all converged in a single chip, creating a surprisingly comprehensive performance.
In addition to this, the PT2313 also provides a loudness adjustment function and selectable input gain, enabling you to build an efficient electronic audio processor while minimizing the use of external components. This design philosophy seeks the ultimate in performance and reliability while maintaining restraint in external components.
All these functions can be programmed through the serial bus, which provides users with convenient and flexible control methods. The pin assignment and application circuit design of the chip have been carefully optimized, which not only can easily realize the PCB layout, but also can effectively save the cost required for audio applications.
The PT2313 package uses a 28-pin DIP/SO. This design is not only compatible with TDA7313, but also gives users more flexibility. You can effortlessly upgrade or replace without redesigning the entire system.
