Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the

INTENDED USE
The MCP6V01 Input Offset Demo Board is intended to provide a simple means to
measure the MCP6V01/2/3 op amp’s input offset voltage (VOS) under a variety of bias
conditions. This VOS includes the specified input offset voltage value found in the data
sheet plus changes due to power supply voltage (PSRR), common mode voltage
(CMRR), output voltage (AOL) and temperature (ΔVOS/ΔTA).

This circuit does the following:
• Supports Microchip’s auto-zeroed, single op amps:
- SOIC-8 package
- Used as both Device Under Test (DUT) and in a difference amplifier
• Test points for connecting lab equipment
• Single supply configuration
• The bias inputs VDD, VCM and GND set the conditions for the DUT
• The VDD/2 Reference uses a resistor ladder to divide VDD in half, then buffers that
voltage with an op amp in unity gain
• The VCM Reference:
- Has a resistor divider at the input that sets VCM = VDD/2 when that input is left
open
- When VCM is driven by an external voltage source, the resistor divider has no
effect on VCM
- VCM is buffered
• The High Gain Feedback Network and DUT together:
- Have a noise gain of GN ≈ 10.0 kV/V
- Have a common mode gain of 1 V/V
- Produce an output voltage of GNVOS + VCM
DS51801A-page 6

Product Overview
• The Difference Amplifier (Diff. Amp.):
- Rejects the DUT’s common mode output (VCM)
- Provides additional gain (GDA ≈ 10.0 V/V) to the term GNVOS at the DUT’s
output
- Shifts the output so it is centered on the reference VREF = VDD/2
- Produce an output voltage of GDAGNVOS + VDD/2
The inputs:
• Allow the DUT to be biased at most valid bias points
• Allow VCM to set by the circuit at VDD/2, or set by the user
The outputs:
• Make it easy to measure the important bias voltages VDD/2 and VCM
• Make it easy to measure VM – VDD/2 = GDAGNVOS

2.4
OPERATING CONDITIONS
This board works most effectively at room temperature (near +25°C). Measurements
at other temperatures should be done in an oven where the air velocity is minimal.
The power supply (VDD) should be between 1.8V and 5.5V.
The common mode voltage (VCM) needs to be between 0.3V and VDD – 0.3V for proper
operation of this demo board.
2.5
CALCULATING THE DUT’S INPUT OFFSET VOLTAGE
The DUT’s total input offset voltage (VOST) can be calculated from a measurement as
shown in Equation 2-1.
EQUATION 2-1:
V OST = ( V M – V DD ⁄ 2 ) ⋅ ( 1 ⁄ ( G DA G N ) )
Where:
1/(GDAGN) ≈ 10.0 µV/V
2.6
CONVERTING INPUT OFFSET VOLTAGE TO OTHER PARAMETERS
2.6.1
Theory
Changing the bias voltages changes the input offset voltage. Microchip’s application
note AN1177 discusses in detail how these changes in VOS are related to specifications
found in our data sheets. The following list summarizes the parameters that contribute
to VOST:
• Specified Input Offset Voltage:
- VOS = Input offset at the specified bias point
• DC Common Mode Rejection Ratio:
- CMRR = ΔVCM/ΔVOS
• DC Power Supply Rejection Ratio:
- PSRR = (ΔVDD – ΔVSS)/ΔVOS
• DC Open-Loop Gain:
- AOL = ΔVOUT/ΔVOS
• Input Offset Drift over Temperature:
- ΔVOS/ΔTA
Note:
DS51801A-page 10
The data sheet Input Offset Voltage (VOS) specification applies to one bias
point and temperature only. The total input offset voltage (VOST) includes
VOS and other changes in input offset as bias voltages and temperature
change.
© 2009 Microchip Technology Inc.
Installation and Operation
Example 2-1 gives an example of how VOST changes with the common mode input
voltage (VCM).
EXAMPLE 2-1:
COMMON MODE CHANGE EXAMPLE
Given:
VOST = 0.5 µV,
VCM = 0V
VOST = 1.0 µV,
VCM = 5V
Then:
ΔVOST = 0.5 µV
ΔVCM = 5.0V
CMRR = 5.0V / 0.5 µV
= 10 V/µV
= 140 dB
2.6.2
Application
When the common mode voltage (VCM) is changed on this demo board, the output
voltage (VOUT) is forced to change by the same amount. There is no means provided
to independently change VCM and VOUT. Thus, it is not possible to separate the
Open-Loop Gain (AOL) effect from the CMRR effect using this board.
Note:
VOUT cannot be changed independently of VCM, so AOL and CMRR cannot
be distinguished using this circuit.
Since AOL is usually much better than CMRR for the MCP6V0X op amps, we can
attribute most of the change to CMRR and ignore AOL in most cases. Table 2-1 shows
one possible measurement matrix that will allow the user to estimate key parameters
for the DUT.

2.7
REDUCING THE MEASUREMENT NOISE
The noise seen in the measurements is a result of the design choices made for the
MCP6V01 Input Offset Demo Board. The components R12 and C5 set a lowpass pole
at 0.16 Hz, which gives reasonable noise performance (±0.2 µVPK referred to the input
of the DUT) and settling time (1 to 2 seconds).
To achieve lower noise in your results, average many measurements together. For
instance, measuring the output (VM – VDD/2) once a second for 16 seconds (16
samples) should produce an estimate with noise √16 = 4 times lower (i.e., ±0.05 µVPK).
There is a practical limit on increasing the sample rate; the noise does not improve
significantly after a certain point. The analog lowpass pole at 0.16 Hz causes closely
spaced samples to be correlated. To avoid the overhead caused by sampling too fast,
keep the sampling period near or above the pole’s time constant (1.0s); this gives a
minimum sample rate of 1 sample per second.
Note:
DS51801A-page 12
Sampling much faster than 1 SPS will not improve the averaged noise of
this board’s output significantly.

CHANGING THE DUT
Change the DUT (see Figure 3-1) to the MCP6V06 Op Amp as follows:
1. Remove U1 from the PCB, using a de-soldering tool.
2. Solder a MCP6V06 op amp in its place. Use a MCP6V06 in a SOIC-8 package.
Pin 1 is next to the U1 reference designator on the PCB (not next to the DUT
label)

CONNECTING A CHIP SELECT PIN TO GROUND
The DUT can be changed to the MCP6V03 or MCP6V08 op amps with chip select. If
desired, their Chip Select pin (pin 8) can be forced to ground. This is done as follows
(see Figure 3-2):
1. Solder one end of a wire to the DUT’s pin 8. Pin 8 is next to the U1 reference
designator on the PCB (not next to the DUT label)
2. Solder the other end of the wire the closest ground via on the PCB. The striped
green arrow to the right in the figure shows the location. The solid green curve
represents the wire.
