NJU7505

Note 1) If the IC are used on condition above the absolute maximum ratings, the IC may be destroyed. Using the IC within electric characteristic conditions will cause malfunction and poor reliability.
Note 2) All voltage values are specified as V_SS = 0V.
Note 3) When the voltage of the RST/CLKO terminal is gotten over the VSS level, the diode should be connected between the RST/CLK0 terminal and the external.
Note 4) Decoupling capacitor should be connected between the V_DD terminal and the VSS due to the stabilization of the operation.
Note 5) Applied to the AIN or the OSC2 terminals.
Note 6) Applied to the RST/CLKO terminal.

The NJU7505 is a band pass filter for audio spectrum analyzer display.

NJU7505 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 of NJU7505 is switched by the internal clock.

Therefore, the audio signal of NJU7505 shared of 5 bands is output from a serial output terminal.

The 10 band version of NJU7505 using the double by the cascade connection is prepared.
