Filter off-the-shelf series
4th and 8th– order, Butterworth, Low-Pass Filter Series
Our standard range below consists of 3 filters/decade with cut-off frequencies from 1Hz to 20kHz with values spaced 1,2,5/decade.
These boards support 1, 8th-order filter or 2, 4th-order filters. The two 4th-order filters can have different cut-off frequencies but both must be from the table below.
If you want cut-off frequencies not in the table below, please enter it in the relevant field at the end of this page. There will be a small customisation charge and we may have to buy-in some of the components.
Module order numbers:
The Quad Op-amp
Filters will be supplied with the MCP6L94 op-amp, therefore will work with supply voltages from 2.4V to 6V. The MCP6L94 has a gain-bandwidth product of 10MHz and a slew-rate of 7V/us.
The MCP6L94 op-amp is CMOS, therefore normal anti-static handling precautions should be observed.
Capacitors are 0805, MLCC, 10%, X7R and at least 25V working voltage. R’s are 0805, 1%, E24 series.
