4 Mode Preset Equalizer IC Preliminary 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.
