产品概述

The MAX297ESA+ from Maxim Integrated Products is an 8th-order, lowpass, elliptic, switched-capacitor filter in 8 pin NSOIC package. It is easy to use, 8th-order, lowpass, elliptic, switched-capacitor filter that can be set up with corner frequencies from 0.1Hz to 50KHz. The MAX297's 1.5 transition ratio provides sharp roll off and -80dB of stopband rejection. It has fixed response, so the design task is limited to selecting the clock frequency that controls the filter's corner frequency. An external capacitor is used to generate a clock using the internal oscillator or an external clock signal can be used. An uncommitted op amp (noninverting input grounded) is provided for building a continuous-time lowpass filter for post-filtering or anti-aliasing. Steep roll off and high order makes this filter ideal for anti-aliasing applications that require maximum bandwidth and for communication applications that require filtering signals in close proximity within frequency domain.
  • Single supply range from 4.75V to 11V
  • Clock to corner frequency ratio is 50:1
  • Clock to corner frequency tempco is 4ppm/°C
  • Insertion gain relative to DC gain is 0.11dB at fIN=0.996Fo
  • Passband ripple is 0.23dB
  • Output DC swing is ±4V
  • Output offset voltage is ±150mV
  • Total harmonic distortion is -77dB
  • Internal oscillator frequency is 35KHz
  • Operating temperature range from -40°C to 85°C
