The LTC6256 circuit shown here is a 2nd order, 100kHz, Butterworth lowpass filter. The filter’s differential output maximizes the dynamic range in very low voltage operation. The LTC6255/LTC6256/LTC6257 are single/dual/quad operational amplifiers with low noise, low power, low supply voltage, rail-to-rail input/output. They are unity gain stable with capacitive load up to 100nF. They feature 6.5MHz gain-bandwidth product, 1.8V/μs slew rate while consuming only 65μA of supply current per amplifier operating on supply voltages ranging from 1.8V to 5.25V
