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.
The 10 bands version using the double by the cascade
connection is prepared.
