It features four sound selections, namely: Classical, Pops, Rock and Normal/Flat which may be selected by the 2 control pins (SW1 and SW2). PT2381 has 2 built-in channels - each containing an internal operation amplifier and selectable resistors. Thus, least external components are used. By connecting only 3 capacitors to each channel, the high performance pre-set equalizing function of this IC is achieved. Pin assignments and application circuit are optimized for easy PCB layout and cost saving for audio applications. PT2381 is housed in a 16-Pin DIP or SO Package and is suitable for stereo applications. Features ! CMOS Technology ! Least External Components ! Enhanced Effects of PT2380 !
