MAXIM INTEGRATED / ANALOG DEVICES MAX297CPA Elliptic Lowpass Filter
The MAX297CPA+ is an 8th order, low-pass, elliptic switched capacitor filter housed in an 8-pin DIP package. It offers configurable corner frequencies from 0.1Hz to 50kHz and provides -80dB stopband rejection with a sharp transition ratio of 1.5. The device features a fixed response, simplifying filter design by adjusting the clock frequency, which can be generated internally via an oscillator with an external capacitor or an external clock signal. An uncommitted op-amp (with the non-inverting input grounded) is included for additional filtering or anti-aliasing applications. Its steep roll-off and high order make it suitable for anti-aliasing, signal filtering in close frequency proximity, and communication systems. It operates on a single +5V supply or dual ±5V supplies, with an operating temperature range of 0°C to 70°C. The clock-to-corner frequency ratio is 50:1, with a typical supply current of 15mA at dual ±5V or 7mA at 5V. Passband ripple is 0.23dB, total harmonic distortion plus noise is -77dB, and the internal clock oscillator runs at 35kHz.
