ROHM Semiconductor BA7755AF
The BA7755A and BA7755AF are high-voltage switching ICs designed to switch voltages as high as ± 65VDC or AC120VP-P (f = 70Hz). By combining the BA7755A or BA7755AF with the BA7751ALS recording / playback amplifier, it is possible to construct a compact recording / playback audio circuit. In addition, the BA7755A and BA7755AF are an excellent choice for a wide variety of other high-voltage switching applications.| Part No. | BA7755AF |
