LTC1563-2 is a family of extremely easy-to-use, active RC low pass filters with rail-to-rail inputs and outputs and low DC offset suitable for systems with a resolution of up to 16 bits. The LTC1563-2, with a single resistor value, gives a unity-gain Butterworth response. The proprietary architecture of these parts allows for a simple resistor calculation: R = 10K (256KHz/fC); fC = cut-off frequency, For many applications, this formula is all that is needed to design a filter. By simply utilizing different valued resistors, gain and other responses are achieved. The device features a low power mode, for the lower frequency applications, where the supply current is reduced by an order of magnitude and a near zero power shutdown mode. Applications includes discrete RC active filter replacement, antialiasing filters, smoothing or reconstruction filters, linear phase filtering for data communication and phase locked loops.
- Extremely easy to use, a single resistor value sets the cut-off frequency (256Hz < fC < 256KHz)
- Extremely flexible, different resistor value allow arbitrary transfer functions with or without gain
- Supports cut-off frequencies up to 360KHz using FilterCAD�
- Unity-gain butterworth response uses a single resistor value
- Rail-to-rail input and output voltages, operates from a single 3V (2.7V min) to ±5V supply
- Low noise of 36µVRMS for fC = 25.6KHz, 60µVRMS for fC = 256KHz
- fC accuracy of < ±2% (typ), DC offset of < 1mV
- Cascadable to form 8th order low pass filters
- 16-lead plastic SSOP package
- Operating temperature range from 0°C to 70°C
