PT 2380
Description
PT 2380 is a pre-set equalizer IC utilizing CMOS Technology specially designed for
audio equipment. It features four sound selections, namely: Classical, Pops, Rock
and Normal/Flat which may be selected by the 2 control pins (SW1 and SW2).
PT 2380 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. PT 2380 is housed in a 16-Pin DIP or
SO Package and is suitable for stereo sound applications.
