LA6557H Datenblatt(HTML) 5 Page - Sanyo Semicon Device |
5 / 8 page No. 6350-5/8 LA6557H Continued from preceding page. Pin No. Pin Function Equivalent circuit Regulator input (base of the external pnp transistor) 19 REG-IN Regulator output (collector of the external pnp transistor) 20 REG-OUT Reference voltage input 21 VREF-IN Signal system power supply (shorted to VCC1 and VCC2) 22 VCC-S Output on/off control for channels 1 to 4 (the BTL amplifiers) 25 MUTE MUTE S-GND 100 k Ω 100 k Ω VCC 25 26 1 (12) HM0004 Signal system ground 26 S-GND Channel 5 (VLO) output switching (FWD), logic input to the loading block Channel 5 (VLO) output switching (REV), logic input to the loading block 27 28 FWD REV FWD 27 HM0005 Notes: The center frame (FR) functions as the power system ground. It must be, along with S-GND, at the lowest potential in the system. The power supply pins, VCC-S, VCC1, and VCC2 must be shorted together externally to the IC. |
