NJU7507

The NJU7507 is designed as a band pass filter for audio spectrum analyzer display. It contains high and low band pass filter, CR oscillation circuit, control circuit and DC transfer circuit.

NJU7507 has seven features. (1) Band pass filter for audio spectrum analyzer display. (2) 14 bands extension is available by the cascade connection (version of A: for 7 bands application by the single and version of B is for 14 bands application by the double). (3) BPF using the switched capacitor filter technology. (4) CR oscillation circuit on chip. (5) Power-on initialization circuit on chip. (6) CMOS technology. (7) Package outline - DIP8 / DMP8. That are all the main features.

Some absolute maximum ratings have been concluded into several points of NJU7507 as follow. (1) Its supply voltage is from -0.3V to +7V. (2) Its input voltage is from -0.3V to Vdd+0.3V for Vin and is from -0.3V to 0V for Vio. (3) Its output voltage is from -0.3V to Vdd+0.3V. (4) Its power dissipation is 500mW for DIP and 300mW for DMP. (5) Its operating temperature range is from -30 to +85°C. (6) Its storage temperature range is from -55°C to +125°C.
