2-Channel Audio Processor IC
PT2315A
DESCRIPTION
PT2315A 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 and SOP, PT2315A is pin-to-pin compatible with TDA7315 and is very similar
in performance with the later.
