TSG85 series

The TSG85 series is one kind of switched capacitor mask programmable filter,it has some features such as:(1)cauer type;(2)7th order;(3)stopband attenuation:85 dB(typ);(4)passband ripple:0.15 dB(typ);(5)clock to cut-off freq.ratio:60;(6)clock frequency range:1 TO 1500 Khz;and (7)cut-off frequency range:16 Hz to 25 kHz.Note:for general characteristics,see TSG85XX specifications.For non standard quality level,consult SGS-THOMSON general ordering information.

The filter specifications of TSG85 series can be summerized as:(1)external clock frequency:1 KHz(min) or 1500 KHz(max);(2)internal sampling freq.:0.5 KHz(min) or 750 KHz(max);(3)clock to cutoff fr.ratio:60%;(4)cutoff frequency:0.016 KHz(min) or 25 KHz(max);(5)passband gain:-0.3 dB(min) or 0 dB(max);(6)passband ripple:0.15 dB;(7)level gain:-2.5;(8)PWF resistance:10 to 72 k;(9)input current on PWF:50 to 250 uA;(10)input resistance:3 M;(11)input capacitance:20 pF;(12)signal to noise ratio:85 dB;(13)stopband attenuation:69 dB(min).
