XR-1001

The XR-1001 is a kind of fourth order switched capacitor low pass filter providing 24 dB/octave (butterworth) of roll off outside of the pass band.The typical applications include mechanical processes, telecommunications, instrumentation, anti-alias filters, reconstruction filters, digital signal processing and musical effects.There are some features as follows.First is single 5 V operation.The second is low power consumption.Then is precise filter positioning.Next is stand alone mode with RC or crystal.The fifth is low noise which is -78 dBm (typical).The last one is corner frequency adjustable to 40 kHz.

What comes next is the absolute maximum ratings of XR-1001.The power supply is 14 V.The input signal level is from V+-0.7 to V-+0.7 V.The power dissipation is 385 mW and the derate factor is 5 mW/ above TA=25 for ceramic package.The power dissipation is 300 mW and the derate factor is 6 mW/ above TA=25 for plastic package.The storage temperature is from -65 to +150.The operating temperature is from 0 to +70.

The following is the electrical characteristics of XR-1001(V+=5 VDC,V-=-5 VDC,fCLOCK=1 MHz,RLOAD=1 M,CLOAD=40 pF,TA=25).The minimum VDD (single supply) is 4.5 VDC and the maximum is 11.0 VDC referenced to VSS (Pin 4).The minimum VDD (split supply) is +2.25 VDC and the maximum is 5.5 VDC referenced to AGND (Pin 6).The minimum VSS (split supply) is -5.5 VDC and the maximum is -2.25 VDC referenced to AGND (Pin 6).The minimum IDD (single supply current) is 2.5 mA and the maximum is 3.5 mA at VDD=10.0 VDC.The minimum IDD (split supply current) is 2.5 mA and the maximum is 3.5 mA at VDD=5.0 VDC.The minimum IDD (split supply current) is 1.50 mA and the maximum is 2.25 mA at VDD=2.25 VDC.
