Typical Applications
3.6.1
ANALOG FILTERS
Examples of two second order low pass filters are
shown in Figure 3-10 and Figure 3-11. The filter in Fig-
ure 3-10 can be configured for gain of +1V/V or greater.
The filter in Figure 3-11 can be configured for inverting
gains.

Pass
The MCP601/602/603/604 family of operational ampli-
fiers are particularly well suited for these types of filters.
The low input bias current, which is typically 1pA (up to
60pA at temperature), allows the designer to select
higher value resistors, which in turn reduces the capac-
itive values. This allows the designer to select surface
mount capacitors, which in turn can produce a compact
layout.
The rail-to-rail output operation of the MCP601/602/
603/604 family of amplifiers make these circuits well
suited for single supply operation. Additionally, the wide
bandwidth allows low pass filter design up to 1/10 of the
GBWP or 300kHz.
These filters can be designed using the calculations
provided in the Figures or with Microchip’s interactive
FilterLab
software.
FilterLab
will calculate capacitor
and resistor values, as well as, determine the number
of poles that are required for the application. Finally, the
program will generate a SPICE macromodel, which can
be used for spice simulations.
3.6.2
INSTRUMENTATION AMPLIFIER
CIRCUITS
The instrumentation amplifier has a differential input,
which subtracts one analog signal from another and
rejects common mode signals. This amplifier also pro-
vides a single ended analog output signal. The three op
amp instrumentation amplifier is illustrated in Figure
3-12 and the two op amp instrumentation amplifier is
shown in Figure 3-13.

An instrumentation amplifier can be
built using three operational amplifiers and seven
resistors.

An instrumentation amplifier can also
be built using two operational amplifiers and five
resistors.
