RLAD (RF+RG in Figure 4-1) connects VSS, VOUT, and the inverting input of the internal amplifier. Thus, VSS is coupled
to the internal amplifier and the PSRR spec describes PSRR+ only. It is recommended that the VSS pin be tied directly
to ground to avoid noise problems.
IQ includes current in RLAD (typically 0.6 µA at VOUT = 0.3V), and excludes digital switching currents.

DC Output Voltage Specs / Model
1.1.1
IDEAL MODEL
The ideal SGA output voltage (VOUT) is (see Figure 1-3):
The DC Gain Drift (ΔG/ΔTA) can be calculated from the
change in gE across temperature. This is shown in the
following equation:
EQUATION 1-4:
EQUATION 1-1:
Δg E
ΔG ⁄ ΔT A = G ⋅ ---------- ,
ΔT A
V O_ID = GV IN
in units of V/V/°C
Δg E
ΔG ⁄ ΔT A = 100% ⋅ ---------- ,
ΔT A
Where:
G is the nominal gain
in units of %/°C
V REF = V SS = 0V
VOUT (V)
This equation holds when there are no gain or offset
errors.
1.1.2
LINEAR MODEL
The SGA’s linear region of operation is modeled by the
line VO_LIN shown in Figure 1-3. VO_LIN includes offset
and gain errors, but does not include non-linear effects.

Figure 1-4 shows the Integral Non-Linearity (INL) of the
output voltage. INL is the output non-linearity error not
explained by VO_LIN:
This line’s endpoints are 0.3V from the supply rails
(VO_ID = 0.3V and VDD – 0.3V). The gain error and
input offset voltage specifications (in the electrical
specifications) relate to Figure 1-3 as follows:
EQUATION 1-3:
V2 – V1
g E = 100% ⋅ ----------------------------V DD – 0.6V
V1
V OS = ------------------------- ,
G ( 1 + gE )
OUTPUT NON-LINEARITY
EQUATION 1-5:
INL = V OUT – V O_LIN
The output non-linearity specification (in the Electrical
Specifications, with units of % of FSR) is related to
Figure 1-4 by:
EQUATION 1-6:
G = +1
Where:
V 1 = V OUT – V O_ID ,
V O_ID = 0.3V
V 2 = V OUT – V O_ID ,
V O_ID = V DD – 0.3V
The input offset specification describes VOS at
G = +1 V/V.

V ONL = 100% ⋅ ------------------------------V DD – 0.6V
Where:
V 3 = max ( – INL )
V 4 = max ( INL )
Note that the Full Scale Range (FSR) is VDD – 0.6V
(0.3V to VDD – 0.3V).

Description
Analog Output
The output pin (VOUT) is a low impedance voltage
source. The selected gain (G) and input voltage (VIN)
determine its value.
3.2
Analog Input
The analog inputs (VIN) are high impedance CMOS
inputs with low bias currents. Only three fixed, noninverting gains are available through these inputs.
3.3
Power Supply (VSS and VDD)
The Positive Power Supply Pin (VDD) is 1.8V to 5.5V
higher than the Negative Power Supply Pin (VSS). For
normal operation, the other pins are at voltages
between VSS and VDD.
DS22004B-page 18
Description
Typically, these parts are used in a single (positive)
supply configuration. In this case, VSS is connected to
ground, and VDD is connected to the supply. VDD will
need a local bypass capacitor (typically 0.01 µF to
0.1 µF) within 2 mm of the VDD pin. These parts need
to use a bulk capacitor (typically 1.0 µF to 10 µF) within
100 mm of the VDD pin; it can be shared with nearby
analog parts.
3.4
Digital Inputs
The Chip Select (CS) input is a Schmitt-triggered,
CMOS logic input.
The Gain Select (GSEL) inputs are tri-level digital
inputs. They function similar to normal logic inputs at
low (G = +10) and high voltages (G = +50). The pin can
also be set to mid-supply (G = +1) by a low impedance
source, or by leaving this pin open.

COMPENSATION CAPACITORS
The internal op amp has three compensation
capacitors (comp. caps.) connected to a switching
network. They are selected to give good small signal
bandwidth at high gains, and good slew rate (full power
bandwidth) at low gains. The change in bandwidth as
gain changes is between 250 and 900 kHz. Refer to
Table 4-1 for more information.

G x BW is approximately the Gain Bandwidth
Product of the internal op amp.
FPBW is the Full Power Bandwidth at
VDD = 5.5V, which is based on slew rate (SR).
BW is the closed-loop, small signal –3 dB
bandwidth.
RAIL-TO-RAIL INPUTS
The input stage of the internal op amp uses two
differential input stages in parallel; one operates at low
VIN (input voltage), while the other operates at high VIN.
With this topology, the internal inputs can operate to
0.3V past either supply rail, although the output will clip
the signal before that happens.
The inputs need to be kept within a smaller range to
prevent output clipping. The input offset voltage also
reduces the range; most designs will need the following
for normal operation:

The transition between the two input stage occurs

region of operation.

PHASE REVERSAL
The MCP6G01/1R/1U/2/3/4 amplifier family is
designed with CMOS input devices. It is designed to
not exhibit phase inversion when the input pins exceed
the supply voltages. Figure 2-7 shows an input voltage
exceeding both supplies with no resulting phase
inversion.

INPUT VOLTAGE AND CURRENT
LIMITS
The ESD protection on the inputs can be depicted as
shown in Figure 4-2. This structure was chosen to
protect the input transistors, and to minimize input bias
current (IB). The input ESD diodes clamp the inputs
when they try to go more than one diode drop below
VSS. They also clamp any voltages that go too far
above VDD; their breakdown voltage is high enough to
allow normal operation, and low enough to bypass ESD
events within the specified limits.
VDD Bond
Pad
current into the input pin (VIN) should be very small.
A significant amount of current can flow out of the
inputs when the common mode voltage (VCM) is below
ground (VSS); see Figure 2-17. Applications that are
high impedance may need to limit the useable voltage
range.
4.1.5
RAIL-TO-RAIL OUTPUT
The maximum output voltage swing is the maximum
swing possible under a particular amplifier load current.
The amplifier load current is the sum of the external
load current (IOUT) and the current through the ladder
resistance (ILAD); see Figure 4-4.

Simplified Analog Input ESD
VIN
In order to prevent damage and/or improper operation
of these amplifiers, the circuits they are in must limit the
currents (and voltages) at the VIN pins (see Section
“Absolute Maximum Ratings †” at the beginning of
Section 1.0 “Electrical Characteristics”). Figure 4-3
shows the recommended approach to protecting these
inputs. The internal ESD diodes prevent the input pins
(VIN) from going too far below ground, and the resistor
R1 limits the possible current drawn out of the input pin.
Diode D1 prevents the input pin (VIN) from going too far
above VDD. When implemented as shown, resistor R1
also limits the current through D1.

(RLAD = RF + RG) sets the gain. Placing the gain
switches in series with the inverting input reduces the
parasitic capacitance, distortion, and gain mismatch.
RLAD is an additional load on the output of the SGA and
causes additional current draw from the supplies.
When CS is high, the SGA is shut down (low power).
RLAD is still attached to the VOUT and VSS pins. Thus,
these pins and the internal amplifier’s inverting input
are all connected through RLAD and the output is not
high-Z (unlike the internal op amp).
RLAD contributes to the output noise; see Figure 2-9.

MCP6G01/1R/1U/2/3/4
RLAD is intended to be driven at the VSS pin by a low
impedance voltage source. The power supply driving
the VSS pin should have an output impedance less than
0.1Ω to maintain reasonable gain accuracy.

Gain Select (GSEL)
The amplifier can be set to the gains +1 V/V, +10 V/V,
and +50 V/V using one input pin (GSEL). At the same
time, different compensation capacitors are selected to
optimize the bandwidth vs. slew rate trade-off (see
Table 4-1). Table 4-2 shows how to change the gain
using a GPIO pin on a microcontroller and Table 4-3
shows how to hard wire the gain (i.e., using PCB
wiring).

Capacitive Load and Stability
Large capacitive loads can cause stability problems
and reduced bandwidth for the MCP6G01/1R/1U/2/3/4
family of SGAs (Figure 2-30 and Figure 2-34). As the
load capacitance increases, there is a corresponding
increase in frequency response peaking and step
response overshoot and ringing. This happens
because a large load capacitance decreases the
internal amplifier’s phase margin and bandwidth.
When driving large capacitive loads with these SGAs
(i.e., > 60 pF), a small series resistor at the output
(RISO in Figure 4-5) improves the internal amplifier’s
stability by making the load resistive at higher
frequencies. The bandwidth will be generally lower
than the bandwidth with no capacitive load.

MCP6G03 Chip Select (CS)
The MCP6G03 is a single amplifier with chip select
(CS). When CS is high, the internal op amp is shut
down and its output placed in a high-Z state. The
resistive ladder is always connected between VSS and
VOUT; even in shutdown. This means that the output
resistance will be 350 kΩ (typ.), with a path for output
signals to appear at the input. The supply current at
VSS includes the current through the load resistor and
ladder resistors; it also includes current from the CS pin
to VSS. When CS is low, the amplifier is enabled. If CS
is left floating, the amplifier may not operate properly.

Layout Considerations
Good PC board layout techniques will help achieve the
performance shown in Section 1.0 “Electrical
Characteristics”
and
Section 2.0
“Typical
Performance Curves”. It will also help minimize
Electromagnetic Compatibility (EMC) issues.
Because the MCP6G01/1R/1U/2/3/4 SGAs’ frequency
response reaches unity gain at 10 MHz when G = 50, it
is important to use good PCB layout techniques. Any
parasitic coupling at high frequency might cause
undesired peaking. Filtering high frequency signals
(i.e., fast edge rates) can help.
4.6.1
COMPONENT PLACEMENT
Separate different circuit functions: digital from analog,
low speed from high speed, and low power from high
power. This will reduce crosstalk.
Keep sensitive traces short and straight. Separate
them from interfering components and traces. This is
especially important for high frequency (low rise time)
signals.
4.6.2
SUPPLY BYPASS
Use a local bypass capacitor (0.01 µF to 0.1 µF) within
2 mm of the VDD pin for good, high frequency
performance. It must connect directly to ground.
Use a bulk bypass capacitor (i.e., 1.0 µF to 10 µF)
within 100 mm of the VDD pin. It needs to connect to
ground, and provides large, slow currents. This
capacitor may be shared with other nearby analog
parts.
Ground plane is important, and power plane(s) can
also be of great help. High frequency (e.g., multi-layer
ceramic capacitors), surface mount components
improve the supply’s performance.

FIGURE 4-7:
Positive Feedback Path.
Figure 2-10 shows the crosstalk (referred to input) that
results when a hostile signal is connected to the other
inputs (e.g., VINB through VIND), and the input of
interest (e.g., VINA) has RS connected to GND. A gain
of +50 was chosen for this plot because it
demonstrates the worst-case behavior. Increasing RS
increases the crosstalk as expected. At a source
impedance of 10 MΩ, there is noticeable change in
behavior.
Most designs should use a source resistance (RS) no
larger than 10 MΩ. Careful attention to layout parasitics
and proper component selection will help minimize this
effect. When a source impedance larger than 10 MΩ
must be used, place a capacitor in parallel to CP1 to
reduce the positive feedback. This capacitor needs to
be large enough to overcome gain (or crosstalk)
peaking, yet small enough to allow a reasonable signal
bandwidth.
4.6.4
SIGNAL COUPLING
The input pins of the MCP6G01/1R/1U/2/3/4 family of
SGAs are high impedance. This makes them especially
susceptible to capacitively coupled noise. Using a
ground plane helps reduce this problem.
When noise is capacitively coupled, the ground plane
provides additional shunt capacitance to ground. When
noise is magnetically coupled, the ground plane
reduces the mutual inductance between traces.
Increasing the separation between traces makes a
significant difference.
Changing the direction of one of the traces can also
reduce magnetic coupling. It may help to locate guard
traces next to the victim trace. They should be on both
sides of, and as close as possible to, the victim trace.
Connect the guard traces to the ground plane at both
ends. Also connect long guard traces to the ground
plane in the middle.

Unused Amplifiers
4.8.2
An unused amplifier in a quad package (MCP6G04)
should be configured as shown in Figure 4-8. This
circuit prevents the output from toggling and causing
crosstalk. Because the VIN pin looks like an open
circuit, the GSEL voltage is automatically set at VDD/2,
and the gain is 1 V/V. The output pin provides a
buffered VDD/2 voltage and minimizes the supply
current draw of the unused amplifier.
DRIVING THE GAIN SELECT PIN
WITH A PWM SIGNAL
The circuit in Figure 4-10 uses a PWM output on a PIC
microcontroller (100 kHz clock rate) to drive the Gain
Select input (GSEL). Setting the PWM duty cycle to
0%, 50% or 100% gives a GSEL voltage of 0V, VDD/2
or VDD, respectively (G = 10, 1 or 50).

The PWM clock rate needs to be fast so it is easily

and it needs to be slow enough for good accuracy and
low crosstalk. This filter reduces the ripple at the GSEL
pin to about 7 mVP-P at VDD = 5.0V. The 10% settling
time is about 200 µs; the filter limits how quickly the
gain can be changed. Scale the resistors and/or

the gain on the SGA. Just as a hand-held multimeter
uses different measurement ranges to obtain the best
results, this circuit makes it easy to set a high gain for
small signals and a low gain for large signals. As a
result, the required dynamic range at the SGA’s output
is less than at its input (by up to 34 dB).

Figure 4-12 shows a circuit using a MCP6271 at a gain
of +10 in front of a MCP6G01. This shifts the overall
gain range to +10 V/V to +500 V/V (from +1 V/V to
+50 V/V).

ADC DRIVER
This family of SGAs is well suited for driving Analog-toDigital Converters (ADC). The gains (1, 10, and 50)
effectively increase the ADC’s input resolution by a
factor of as large as 50 (i.e., by 5.6 bits). This works
well for applications needing relative accuracy more
than absolute accuracy (e.g., power monitoring); see
Figure 4-14.

SGA with Higher Gain
It is also easy to shift the gain range to lower gains (see
Figure 4-13). The MCP6001 acts as a unity gain buffer,
and the resistive voltage divider shifts the gain range
down to +0.1 V/V to +5.0 V/V (from +1 V/V to +50 V/V).

The low-pass filter in the block diagram reduces the
integrated noise at the MCP6G01’s output and serves
as an anti-aliasing filter. This filter may be designed
using Microchip’s FilterLab® software, available at
www.microchip.com.
