... Bessel), while at three times the cutoff frequency, the filter attains 68dB attenuation (vs 30dB for Bessel). The cutoff frequency of the LTC1064-7 is tuned via an external TTL or CMOS clock. The LTC1064-7 features wide dynamic range. With single 5V supply, the S/N + THD is 76dB. Optimum 92dB S/N is obtained with ± ...
