DESCRIPTION
PT2351 is an 8-pin subwoofer cross-over low pass filter chip utilizing CMOS Technology having a slope rate of -12dB/oct or -18 dB/oct. Using an external capacitor, the roll-off point can be adjusted to meet your needs or taste. PT2351 has low distortion, high input impedance and low output impedance design. The application circuit and pin assignments are optimized for easy PCB Layout and cost saving benefits.
