NJM2525
4CH VIDEO AMPLIFIER WITH SW&SD/ HD LPF
s GENERAL DESCRIPTION The NJM2525 is 4ch video amplifier with SD/HD LPF. The NJM2525 includes 2in-1out selector for the composite and component signal. The isolation amplifier eliminates the common mode noise from external equipment. The NJM2525 is suitable for the AV equipment such as the home theater systems and AV receivers that switch the internal Video signal and the external Video signal. s FEATURES q Operating Voltage q SD/ HD LPF q 6dB amplifier q 75Ω Driver Circuit q Y/C MIX Circuit q Isolation amplifier q Power Save Circuit q Bipolar Technology q Package Outline s BLOCK DIAGRAM
