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 I2C 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.
