NJM2512 47µ µF AC-Coupling Capacitor Low Voltage Video Driver with LPF ■GENERAL DESCRIPTION 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. 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. ■FEATURES ● Operating Voltage ● AC-Coupling capacitor ● 6dB Amplifier ● 75Ω Driver ● Internal LPF ● Power-save Circuit ● Bipolar Technology ● Package Outline ■PACKAGE OUTLINE NJM2512RB1 3.0 to 6.0V 47µF 0dBtyp.at 4.5MHz -33dBtyp.at 19MHz TVSP8 ■PIN CONNECTION 1 8 2 7 3 6 4 5 1: SSIGV 2: VSAG 3: SREFV 4: VIN 5: GND 6: Power Save 7: VOUT + 8: V ■BLOCK DIAGRAM GND V+ 6dB VIN 75ΩDRV 4.5MHz LPF 0.1µF VOUT 47µF 75Ω 75Ω + VSAG CLAMP SREFV ASC Ver.0.5 SSIGV PS -1- NJM2512 ■ABSOLUTE MAXIMUM RATINGS (Ta=25°C) PARAMETER SYMBOL RATINGS UNIT + Supply Voltage V 7.0 V Power Dissipation PD 580(Note1) mW Topr Tstg -40 to +85 -40 to +150 °C °C Operating Temperature Range Storage Temperature Range (Note1) At on a board of EIA/JEDEC specification.

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.
