1.3.2
Sensor Connector
The sensor connector, J5, is a 6-pin screw terminal configured to accommodate a
variety of sensors. Bridge-type sensors can have their excitation voltage connected to
either the VDUT supply of the evaluation board or to another externally-supplied source.
In addition, the connector provides sense line connections.
1.3.3
Instrumentation Amplifier
The MCP6N16 is a zero-drift instrumentation amplifier designed for single-supply
operation with rail-to-rail input (no common mode crossover distortion) and output
performance. The device can be operated over a supply range of +1.8V to +5.5V
(VDUT). The evaluation board is populated with the MCP6N16-100, which is designed
to be operated with a gain of +100V/V and higher. At a gain of +100V/V, the
MCP6N16-100 offers a typical input signal range of 34 mVP-P, with a maximum offset
voltage of only 17 µV. It offers a very low noise of 0.93 µVP-P (0.1 to 10 Hz), and a
voltage noise density of 45 nV/√Hz.
The RC input filter provides a low-pass function for both common mode (CM) and
differential mode (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. The output filter provides a low-pass function for both CM and DM signals.
It is slow in order to minimize noise and interference.
1.3.4
VREF
The evaluation board uses the precision voltage reference IC MCP1525 to provide a
+2.5V reference voltage (VREF) with an accuracy of better than 1%. This voltage can
be adjusted and used as an external reference voltage for the MCP6N16 to level shift
its output voltage to a desired level.
1.3.5
Power Supply Connector
The evaluation board allows for a number of supply configurations using connector J2.
In its default configuration, the board can be operated with just one external lab supply
voltage (Jumper J1 is installed and connects the VDUT and VS+ lines together).
Shown in Figure 1-2 and Figure 1-3 are the 3D views of the evaluation board’s top and
bottom side. The evaluation board measures approximately 4.3'' x 2.4''
(10.9 cm x 6.1 cm).

DETAILED CIRCUIT DESCRIPTIONS
2.4.1
Power Supply
When in its default configuration, the evaluation board requires only one external power
supply, typically a +5.0V single supply voltage applied to pin 3 (or 4) of the 4-pin screw
terminal J2. The ground connection (GND) should be made to pin 1 of J2; see
Figure 2-1.
Note 1:
Jumper J1 is installed by default and therefore shorts the VDUT and VS+
supply voltage connections together. In this configuration, the evaluation
board can be operated with full functionality within a voltage range of
+2.7V to +5.5V.
2:
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.
The LEDs D1 and D2 will indicate that power is applied to the VDUT and VS+ supplies.

Power Supply Circuit and Connections.
The power plane of the evaluation board is separated into two segments: one labeled
VDUT and one VS+. The VDUT supply line mainly powers the MCP6N16 instrumentation
amplifier. It is also connected to be the supply rail for any attached bridge sensor (VB+,
VB-). The VS+ supply powers the precision voltage reference MCP1525, and the
Zero-Drift op-amp MCP6V11.
The evaluation board is also preconfigured to be operated from a +3.3V supply rail
when connected up to a PIC® microcontroller. Jumper 8 is needed to make this
connection, while any external lab supplies must be disconnected from the power
connector J2.
In addition to connecting the supply voltages, pin 2 of terminal J2 can be used to apply
an external common-mode voltage (VCM) for biasing the inputs of the instrumentation
amplifier MCP6N16 (see Figure 2-2). Further details on this function can be found in
Section 2.4.3 “Instrumentation Amplifier”.
DS50002365A-page 18

Installation and Operation
2.4.2
Sensor Connection
The evaluation board provides a 6-pin screw terminal to allow for a variety of sensors
to be connected, and, based on the specific sensor, the user can select either a 2-, 3-,
4- or 6-wire interface configuration. Figure 2-3 shows the screw-terminal with its pin
descriptions: AIN+ and AIN- are the differential signal inputs for the instrumentation
amplifier. To facilitate a quick noise test, install a jumper on J6 that will shorten the AIN+
and AIN- lines together.
Note:
The evaluation board comes with the MCP6N16 device set for a gain of
101V/V; when operating with a +5.0V supply rail the typical full-scale input
range of the MCP6N16-100 is about 34 mVP-P.
VB+ and VB- are the two connections for the excitation voltage for the sensor (usage
depends on sensor type). In its standard configuration, a jumper is installed at J3,
connecting the supply voltage VDUT to VB+ (typically +5.0V). Resistor R1 and R17
allow for any additional series resistance to be added into the sensor excitation lines.
An additional option for providing excitation is through the DAC1 line by using an
external supply (e.g. current source) or stimulus. For this, jumper J3 needs to be
adjusted accordingly. Another option for the user is to superimpose an AC signal
(through C4) onto a DC excitation voltage to simulate an AC error signal that the sensor
might pick up and examine the common-mode rejection behavior of the filters and
instrumentation amplifier.

Instrumentation Amplifier
The MCP6N16 is a zero-drift instrumentation amplifier designed for single-supply
operation with rail-to-rail input (no common mode crossover distortion) and output
performance. Its design is based on a current feedback architecture which allows for
the output voltage to be independently set regardless of the input common-mode
voltage. 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 (RF and RG). Refer to the MCP6N16 data sheet for
more details on its operation and specifications.

Installation and Operation
2.4.3.1
INPUT AC-COUPLING
With resistors R6 and R9 (both 0Ω) populated, the signal inputs on the evaluation board
are DC coupled to the inputs of the instrumentation amplifier MCP6N16. Alternatively,
the inputs can be configured for AC coupling. For this, replace resistors R6 and R9 with
ceramic capacitors (0.1 µF, or as required). In this AC-coupling configuration, it is
important to provide a DC bias path for the inputs of the instrumentation amplifier. This
is accomplished with resistors R13 and R14, which are already installed. They can be
either referenced to ground or an external common-mode voltage (VCM) by setting the
jumper J10 accordingly. The resistor along with the coupling capacitors will also result
in a high-pass filter; for example using 0.1 µF capacitors and 200 kΩ resistor will set
the -3 dB frequency at about 8 Hz.
Note:
2.4.3.2
When using resistors R13 and R14, the input impedance at the AIN+ and
AIN- is determined by the value of these resistors. Removing the resistors
will restore the high input impedance provided by the MCP6N16, but will
also eliminate the option of using an external common-mode voltage (VCM)
through J2.
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. The evaluation board
includes additional external RC filtering comprised of common-mode and
differential-mode filters which will limit the input signal bandwidth according to
Equation 2-1.
EQUATION 2-1:
1
1
- = ------------------------------------Common-Mode filter: f CM = -------------------------------- 2 R7 C6 2 R10 C9
Note that capacitors C6 and C9 have been selected with a lower tolerance of 5%,
instead of the typical 10%, to improve time constant matching between R7C6 and
R10C9 and consequently limit the CMRR degradation caused by such mismatches.
The -3 dB frequency for these filters is about 8 kHz. The MCP6N16-100 maintains a
very high common-mode rejection, CMRR of > 100 dB out to 100 kHz. This allows for
a relatively high corner frequency to be chosen for this filter and therefore reduces the
series resistor (i.e. R7 and R10) value, which may otherwise cause unwanted offset
and noise contributions at the input of the high-gain instrumentation amplifier.
It is recommended to keep the value of C7 at least ten times larger than C6 and C9 to
reduce the effects of the time constant mismatch and improve performance.
EQUATION 2-2:
1
Differential-Mode filter: fDIFF = ---------------------------------------------------------------------- 2 R7 + R10 C7 + C6
-------
2
1
with R7 = R10: f DIFF = ---------------------------------------------- 2 R 2C7 + C6
The differential-mode input filter has its -3 dB frequency corner at about 378 Hz. Note
that the filter will start affecting the gain at a much lower frequency, for example the
input signal will be lowered by 1% at about 54 Hz.

MCP6N16 Evaluation Board User’s Guide
The complete frequency response of the signal path consisting of the input filter,
MCP6N16 and the output filter is shown in Figure 2-6. Here, the -3 dB frequency corner
is at approximately 300 Hz with a flat gain out to about 30 Hz.

Figure 2-7 shows the signal path including the input and output 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. Once the actual nature of the sensor/input signal and its bandwidth is known,
the filter poles can be adjusted to limit further the noise-bandwidth and to optimize the
interface to an A/D converter that may follow.

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. The gain is set with two
external resistors and follows the relationship shown in Equation 2-3.
EQUATION 2-3:
Differential Signal Gain:
R11
G1 = 1 + ---------- = 101
R18
1 + R11 + R16
G 2 = ------------------------------------------ = 301
R18
The transfer function of the MCP6N16 is given as shown in Equation 2-4.
EQUATION 2-4:
VOUT = G (VIP - VIM) + VREF
Table 2-3 lists suggested resistor values for the feedback (RF) and gain resistors (RG),
using 1% standard resistor, for a desired gain. Large value resistors should be avoided
as they may start to contribute noise. To keep the output loading minimal and maintain
optimum linearity the selection of the gain setting resistors should take any additional
load resistance into account, according to Equation 2-5.

Note:
The MCP6N16-100 is internally compensated to be used for gains higher
or equal to 100. If lower gains are desired, consider using alternate models,
for example the MCP6N16-010 for gains higher or equal to 10, or the
MCP6N16-001 for gains higher or equal to 1.
Capacitor C11 in combination with R16 can be added to the feedback network to form
an additional low-pass filter of approximately 800 Hz (with C11 = 0.01 µF). This may be
used as an alternate filter option instead of the common/differential-mode RC filter at
the output of the MCP6N16 consisting of R8, R19, C8, C10, C12.

2.4.3.4
ENABLE FUNCTION
The MCP6N16 instrumentation amplifier features an Enable-pin (EN); since there is no
internal pull-up resistor, the MCP6N16 on the evaluation board is placed into the
Enable state (operational) by an external pull-up resistor (R4). The evaluation board
provides two options for the user to examine the part’s performance in its power-down
state: either in a static mode, by inserting a jumper on J4, or through the CS1 line. If
this line is connected to an external stimulus (CMOS levels), the dynamic performance
can be examined.
2.4.4
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. Refer to the MCP6N16
data sheet for further details.
The MCP1525 (U2) is a precision, low-power voltage reference with an output voltage
of +2.5V. Resistor R23 is a 25-turn potentiometer that is used to provide an adjustment
range of +0.025V to +3.0V at the output of the reference buffer U4. The buffer amplifier
uses the MCP6V11, a zero-drift micro-power operational amplifier that is configured for
a gain of +1.2V/V. To minimize noise the bandwidth of this amplifier stage is limited to
about 8 Hz using capacitor C15, which is placed in parallel with the feedback resistor.

An alternate method to adjusting the reference voltage manually with R23 is offered
with the Digital Potentiometer device MCP4018. The use of this device will require the
user to connect the MCP4018 I2C™ interface to an external controller (e.g. a PIC
microcontroller). Jumper J13 is used to switch between the manual option on the
MCP4018.
