The LTC1569-6 and LTC1569-7 are monolithic 10th order linear phase low pass filters. These are the first sampled data filters 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 family is 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. Thus, the LTC1569 family is an excellent choice in applications with demanding specifications for rejection of frequency components outside the passband. With up to 300kHz cutoff, the LTC1569-7 is intended for systems needing maximum bandwidth whereas the LTC1569-6 offers a low power solution with consumption as low as 8mW (fc = 4kHz). Operating from 3V to ±5V supplies, the LTC1569-6 and LTC1569-7 are available in the 8-pin SOIC package.
