LTC1062 is a 5th order all pole maximally flat low pass filter with no DC error. Its unusual architecture puts the filter outside the DC path so DC offset and low frequency noise problems are eliminated. This makes the device very useful for low pass filters where DC accuracy is important. The filter input and output are simultaneously taken across an external resistor. It is coupled to the signal through an external capacitor. This RC reacts with the internal switched capacitor network to form a 5th order roll off at the output. The filter cut-off frequency is set by an internal clock that can be externally driven. The clock-to-cut-off frequency ratio is typically 100:1, allowing the clock ripple to be easily removed. It is widely used in application such as 60Hz low pass filters, antialiasing filter, low level filtering, rolling off AC signals from High DC voltages, digital voltmeters, scales, strain gauges etc.
