NJM2512A

NJM2512A 47µF AC-Coupling Capacitor Low Voltage Video Driver with LPF sGENERAL DESCRIPTION The NJM2512A is a Low Voltage Video Amplifier featuring small AC-coupling Capacitor. The NJRC original Technology “ASC(Advanced SAG Correction)” realizes 47µF AC-Coupling Capacitor which enables to downsize mounting space. No worrying about beat noise caused by charge-pump circuit, and over-current caused by circuit short out than Capacitor-less video driver. The NJM2512A is suitable for any video application.
