Capacitorless Second-Order
Low-Pass filter with Chip Select
The low-pass filter shown in Figure 4-16 does not
require external capacitors and uses only three exter-
nal resistors; the op amp’s GBWP sets the corner
frequency. R
1
and R
2
are used to set the circuit gain
and R
3
is used to set the Q. To avoid gain peaking in
the frequency response, Q needs to be low (lower
values need to be selected for R
3
). Note that the
amplifier bandwidth varies greatly over temperature
and process. However, this configuration provides a
low cost solution for applications with high bandwidth
requirements.

DESIGN TOOLS
Microchip provides the basic design tools needed for
the MCP6291/2/3/4/5 family of op amps.
5.1
SPICE Macro Model
The
MCP6291/2/3/4/5 op amps is available on our web site
at www.microchip.com. This model is intended to be an
initial design tool that works well in the op amp’s linear
region of operation at room temperature. See the
macro model file for information on its capabilities.
Bench testing is a very important part of any design and
cannot be replaced with simulations. Also, simulation
results using this macro model need to be validated by
comparing them to the data sheet specifications and
characteristic curves.

FilterLab
Software
Microchip’s FilterLab software is an innovative tool that
simplifies analog active-filter (using op amps) design.
Available at no cost from our web site at
www.microchip.com, the FilterLab design tool provides
full schematic diagrams of the filter circuit with
component values. It also outputs the filter circuit in
SPICE format, which can be used with the macro
model to simulate actual filter performance.
