BAND PASS FILTER FOR AUDIO SPECTRUM ANALYZER DISPLAY

! GENERAL DESCRIPTION

! PACKAGE OUTLINE

The NJU7505 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.

NJU7505XD

NJU7505XM

The 10 bands version using the double by the cascade

connection is prepared.
