LTC1069-1CS8#PBF

LTC1069-1 is a monolithic 8th order low pass filter featuring clock-tunable cut-off frequency. The cut-off frequency (fCUTOFF) of the device is equal to the clock frequency divided by 100. The gain at fCUTOFF is -0.7dB and the typical passband ripple is ±0.15dB upto 0.9fCUTOFF. F. The stopband attenuation of the device features a progressive elliptic response reaching 20dB attenuation at 1.2fCUTOFF, 52dB attenuation at 1.4fCUTOFF and 70dB attenuation at 2fCUTOFF. It is widely used in application such as telecommunication filters, antialiasing filters etc.
