DC626A-A

DC626A-A is a demo board for the LTC1569-6 linear phase, DC accurate, low power, 10th order low pass filter. LTC1569-6 is monolithic 10th order linear phase low pass filters. This is the first sampled data filter in the industry to provide accurate control of the cutoff frequency without the need for an external clock. Offered in the 8-lead SOIC package, the LTC1569 tunable with a single resistor. The LTC1569’s ease of use, accurate tuning and small package combined with its precision performance and high selectivity is practically impossible to achieve with discrete components. Its root raised cosine gain response and linear phase results in excellent lowpass characteristics with steep selectivity ideal for use in data communication and data acquisition systems. The filter attenuation is 50dB at 1.5 times the filter cutoff and 80dB at 6 times the cutoff frequency.
