3D Effect IC Pr eliminary PT2386
DESCRIPTION
PT2386 is an enhanced 3DAudio Effect IC utilizing CMOS Technology specially designed for the new
generation of audio equipments. PT2386 features a bass booster function as well as the latest PTC 3D
Audio T echnology, thereby, guaranteeing highly powerful, extensive and true-to-life stereo sound stage
effect. Furthermore, it does not need any additional complex external circuits making it very easy to
design into any audio equipment products. Housed in 28 pins DIP package, PT2386 can operate at a
wide operating voltage range and has low power consumption. Pin assignments and application circuit
are optimized for easy PCB layout and cost saving benefits.
