Product Overview

The LTC1563-3CGN#PBF is an 4th order active RC Low pass Filter with rail-to-rail inputs and outputs and low DC offset suitable for systems with a resolution of up to 16bits. The LTC1563-3 with a single resistor value, gives an unity-gain Bessel response. By simply utilizing different valued resistors, gain and other responses are achieved. The LTC1563-3 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. It is DC offset trimmed in a 2-step manner. To obtain maximum performance, the output loading effects must be considered. Output loading issues can be divided into resistive effects and capacitive effects.
  • Extremely easy to use, a single resistor value sets the cut-off frequency (256Hz < fC <256kHz)
  • Extremely flexible, different resistor values allow arbitrary transfer functions with/without gain
  • Supports cut-off frequencies up to 360kHz using FilterCAD™
  • Unity-gain Bessel response uses a single resistor value
  • Different resistor values allow other responses with or without gain
  • Rail-to-rail input and output voltages
  • Operates from a single 3V (2.7V minimum) to ±5V supply
  • Low noise (36µVRMS for fC = 25.6kHz, 60µVRMS for fC = 256kHz)
  • <±2% Typical cut-OFF frequency accuracy
  • <1mV DC offset
  • Cascadable to form 8th order low pass filters
