HSH8927 is PHILIPS out of the company's new two-channel audio circuit (Circuit), which arranged to enter squelch function (Function), the current on/off machine (electric current) rushing sound, overload and short circuit protection (Protection/conservancy/guardianship), suitable for Hi-Fi amplifier for home theater package.ANaservice manual download site
The IC is a single column 9-pin package, the main electrical parameters: voltage typical for 16V, limits to 20V, when output power VCC= 18V, 4 ohm load per channel on 30W,BTL connection up to 80W; total distortion factor is 0. 15%, true stereo separation is 65dB; quiescent current is 70mA; closed loop voltage gain 31dB. PIN function: ¢Ù r-Mono-phase end; II r-inverting input c neutral about r channel output ¢Ý Dianyuan power supply negative pole; f l channel output; sadly Dianyuan positive power supply; h l-inverting input; Krispy Kreme l noninverting input. Figure 1 is a HSH8927 two-channel power amplifier for simple circuit using double Dianyuan power supply, suitable for connection of desktop cassette recorder, if VCD audio signal, you must add front-drive amplifier. If you need greater power output, the choice of BTL circuit of Figure 2, the output power up to 80W. IC1 is an integrated 5-band equalizer, adjust the potentiometer can be 70Hz, 330Hz, 1kHz, 3. 3kHz, 10kHz, an audio upgrade or attenuation of frequencies.ANaservice manual download site
