Typical Applications
4.4.1
HIGH INPUT IMPEDANCE
DIFFERENCE AMPLIFIER
Figure 4-11 shows the MCP6N11 used as a difference
amplifier. The inputs are high impedance and give good
CMRR performance.

Difference Amplifier.
4.4.2
DIFFERENCE AMPLIFIER FOR
VERY LARGE COMMON MODE
SIGNALS
Figure 4-12 shows the MCP6N11 INA used as a
difference amplifier for signals with a very large
common mode component. The input resistor dividers
(R1 and R2) ensure that the voltages at the INA’s inputs
are within their range of normal operation. The
capacitors C1, with the parasitic capacitances C2 (the
resistors’ parasitic capacitance plus the INA’s input
common mode capacitance, CCM), set the same
division ratio, so that high-frequency signals (e.g., a
step in voltage) have the same gain. Select the INA
gain to compensate for R1 and R2’s attenuation. Select
R1 and R2’s tolerances for good CMRR.

4.4.3
HIGH SIDE CURRENT DETECTOR
Figure 4-13 shows the MCP6N11 INA used as to detect
and amplify the high side current in a battery powered
design. The INA gain is set at 21 V/V, so VOUT changes
210 mV for every 1 mA of IDD current. The best GMIN
option to pick would be a gain of 10 (MCP6N11-010).

4.4.4
WHEATSTONE BRIDGE
shows
the
MCP6N11
single
instrumentation amp used to condition the signal from
a Wheatstone bridge (e.g., strain gage). The overall
INA gain is set at 201 V/V. The best GMIN option to pick,
for this gain, is 100 V/V (MCP6N11-100).
