(DM) signals. They are fast enough to follow supply variations and to let the MCP6N16 reject CM mains noise (e.g., harmonics of 50 or 60 Hz). In its default setting, it is set to a gain of +101V/V; using jumper J9, it can be reconfigured for gain of +301V/V. -

3. Measure the DC voltage V at TP5 with a voltmeter: it is suggested to set this to +2.5V (adjust with R23 if necessary) to level shift the output of the MCP6N16 centered between the supply rails. 4. Connect an oscilloscope to the output at either TP1 (V ) or J7 and observe the output signal of the MCP6N16. -

Use this to reference V pin of the MCP6N16 to ground 2 - 3 Closed In this setting the output of the MCP6N16 will be level shifted by the external V voltage. 1 - 2 Open Use this setting in conjunction with the DigiPot MCP4018. -
Page 18: Detailed Circuit Descriptions
Removing jumper J1 will necessitate a second external power supply to maintain full operation of the evaluation board. This will allow the MCP6N16 to be operated over its full supply range of +1.8V to +5.5V. The VS+ supply should not be lower than +2.7V, in order to maintain operation of the +2.5V precision reference IC MCP1525. -
Page 19: Sensor Connection
To facilitate a quick noise test, install a jumper on J6 that will shorten the AIN+ and AIN- lines together. The evaluation board comes with the MCP6N16 device set for a gain of Note: 101V/V; when operating with a +5.0V supply rail the typical full-scale input... -
Page 20: Instrumentation Amplifier
The gain of the instrumentation amplifier is set by two external resistors, but unlike most INAs, the gain accuracy of the MCP6N16 is only determined by the relative match of those external resistors (R and R ). - Page 21 2.4.3.2 INPUT AND OUTPUT FILTERING The MCP6N16 features internal EMI filters on all four of its inputs that are very effective suppressing high-frequency signals from interfering and causing unwanted offset voltages. Those internal filters may already be sufficient for some applications and the sensor can be connected directly to the inputs of the MCP6N16.
- Page 22 RC filters of the MCP6N16. The RC output filter is similar to the input filter with the exception that the common-mode pole is set at about 1.59 kHz and the differential pole is at about 756 Hz.
- Page 23 2.4.3.3 INA GAIN SELECTION The evaluation board allows users to quickly set the gain on the MCP6N16 to either 101V/V or 301V/V by setting the jumper on J9 (labeled Gain Select) accordingly. Note that the feedback resistors R11 and R16 are populated with a tolerance of only 0.1% (instead of the standard 1%) to provide a higher gain accuracy.

Page 24: External Vref Circuit
Included on the evaluation board are various options that deliver an external reference voltage to the MCP6N16, which can be used to level shift the output signal. Since the MCP6N16 is configured in a single-supply configuration on the evaluation board, either the input is biased with an appropriate input DC bias voltage to keep the amplifier within its specified input range, or the output needs to be level shifted. -
