NJM2512
47µF AC-Coupling Capacitor
Low Voltage Video Driver with LPF
■GENERAL DESCRIPTION
■PACKAGE OUTLINE
The NJM2512 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.
NJM2512RB1
No worrying about beat noise caused by charge-pump circuit, and
over-current caused by circuit short out than Capacitor-less video
driver.
The NJM2512 is suitable for any video application.

■APPLICATION NOTE
NJM2512 has possibilities that decrease in the capacitance in low-frequency band when the ceramic capacitor is
used(pin7). It is a possibility that the sag is generated when the ceramic capacitor decreases capacity.
Please verify it in consideration of the capacity drop of the ceramic capacitor.
