is low noise, high output-drive capability, high unity-gain and maximum-out-swing bandwidths, low
distortion ,high slew rate, input-protect diodes, and output short-circuit protection. The operational amplifier is
compensated internally for unity-gain operation. The device has specified maximum limits for equivalent input
noise voltage.

3.5.17 function introduction to PT2315
1. Description
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 IIC 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, PT2315is pin-to-pin compatible with TDA7315 and is very similar in performance with
performance with the later.
