NJU7505A

NJU7505A BAND PASS FILTER FOR AUDIO SPECTRUM ANALYZER DISPLAY GENERAL DESCRIPTION The NJU7505A is a band pass filter for audio spectrum analyzer display. It consists of high and low band pass filters, CR oscillation circuit, control circuit and DC transfer circuit. Each band pass filter using the switched capacitor filter technology operates at the shared time by 5 bands which filter constant is switched by the internal clock. Therefore, the audio signal shared of 5 bands is output from a serial output terminal. The 10 bands version using the double by the cascade connection is prepared.
