The MAX280/MXL1062 are 5th-order all-pole instrumentation lowpass filters with no DC error. The filter uses an external resistor and capacitor to isolate the integrated circuit from the DC signal path, thus providing excellent DC accuracy.
The resistor and capacitor, along with the on-chip 4th-order switched capacitor filter, form a 5th-order lowpass filter. Two MAX280/MXL1062s can be cascaded to form a 10th-order lowpass filter. The filter cutoff frequency is set by an internal clock which can be externally driven. The clock to cutoff-frequency ratio is 100: 1, allowing clock ripple to be easily removed.
The MAX280 is an enhanced version of the MXL1062. Enchancements include tighter specifications on the internal clock oscillator frequency and the buffer amplifier offset voltage.
