S3529B

The S3529B is designed as programmable high pass filter. Typical applications include PBX and trunk status monitoring, automatic answering / forwarding / billing systems, adaptive filtering, alarm systems, heating systems, acoustic controllers, specturm analyzers, computer controlled analog circuit testers, medical telemetry / filtering, ECG signal filtering, automotive command selection and filtering.

S3529B has many features. The first one is cutoff frequency selectable in 64 steps via six bit control word. The second one is cutoff frequency range of 10Hz to 20KHz, 40Hz to 20KHz via popular 3.58MHz TV crystal. The third one is seventh order ellipitical filter. The fourth one is passband ripple which would be 0.1dB. The fifth one is stopband attenuation is 51dB for f<0.77fc. The sixth one is clock tunable cutoff frequency continuously variable via external clock. The seventh one is uncommitted input and output op amps for anti-aliasing and smoothing functions. The eighth one is low power CMOS technology. That are all the main features.

Some absolute maximum ratings of S3529B have been concluded into several points as follow. The first one is about its supply voltage (Vdd - Vss) which would be +15.0V. The second one is about its operating temperature range which would be from 0°C to +70°C. The third one is about its storage temperature range which would be from -65°C to +150°C. The fourth one is about its input voltage, all pins which would be from Vss-0.3V to Vdd+0.3V.

Also some DC electrical operating characteristics about S3529B. The first one is about its positive supply which would be min 9.0V and typ 10.0V and max 13.5V. The second one is about its power dissipation at 10V which would be typ 60mW and max 110mW. The third one is about its input resistance which would be min 8M. The fourth one is about its input capacitance which would be max 15.0pF. And so on. For more information please contact us.
