One External R Sets Cutoff Frequency Root Raised Cosine Response Up to 300kHz Cutoff on a Single 5V Supply Up to 150kHz Cutoff on a Single 3V Supply 10th Order, Linear Phase Filter in an SO-8 DC Accurate, VOS(MAX) = 5mV Low Power Modes Differential or Single-Ended Inputs 80dB CMRR (DC) 80dB Signal-to-Noise Ratio, VS = 5V Operates from 3V to ±5V Supplies
Furthermore, its root raised cosine response offers the optimum pulse shaping for PAM data munications. The filter attenuation is 50dB at 1.5
- fCUTOFF, 60dB at 2
- fCUTOFF, and in excess of 80dB at 6
- fCUTOFF....
