2-Channel Audio Processor IC
Description
PT2315
PT2315 is a two-channel digital audio processor utilizing CMOS Technology. Volume,
Bass, Treble and Balance Controls are incorporated into a single chip. Loudness
Function is also provided to build a highly effective electronic audio processor having
the highest performance and reliability with the least external components. All functions
are programmable using the I
2
C Bus. The pin assignments and application circuit are
optimized for easy PCB layout and cost saving advantage for audio application. Housed
in a 20-pin DIP/SO Package, PT2315 is pin-to-pin compatible with TDA7315 and is very
similar in performance with the later.
