SSM2040

The SSM2040 is a four section fifter whose cutoff frequency can be exponentially voltage controlled over a 10000 to 1 range.This flexible building-block can be used in virtually any active filter design including lowpass,bandpass and notch.

Features of the SSM2040  are:(1)+/- 15V supplies;(2)exponetial frequency control response;(4)4 filter sections in one package;(5)low noise;(6)low distortion;(7)guaranteed control rejection characteristics;(8)10000:1 sweep range.

The electrical specifications of the SSM2040 can be summarized as:(1):the parameter is functional range,the Min is 10000:1;(2):the parameter is input offset,each cell,the Max is 2,the Max is 5,the unit is mV;(3):the parameter is input offset,4 cell in series,the Typ is 0.6,the Max is 3,the unit is mV;(4):the parameter is transconductance,the Min is 1/10k,the Typ is 1/5k,the Max is 1/3k,the unit is mhos;(5):the parameter is equiv. input noise,each cell,the Typ is 0.5,the unit is uV RMS;(6):the parameter is distortion,Ein=30 mVpp,the Typ is 0.1,the unit is %;(7):the parameter is tempco of transconductance,the Typ is +0.5,the unit is %/;(8):the parameter is control sensitivity,the Typ is -18,the unit is mV/oct;(9):the parameter is tempco of control sensitivity,the Typ is 0.33,the unit is %/;(10):the parameter is power supply current,the Min is 2,the Typ is 4,the Max is 7,the unit is mA;(11):the parameter is buffer slew rate,the Typ is 2,the unit is V/usec;(12):the parameter is buffer output sink current,the Min is 425,the Typ is 560,the Max is 750,the unit is A.
