The power supply voltage needs to be in the allowed range for the installed operational
amplifiers. Any of Microchip’s op amps that operate below 5.5V can be used. Moreover,
the power supply is protected by a zener diode with nominal voltage 6.2V and
bypassed by a 1.0 µF capacitor. (See Figure 2-3: “Power Supply Block.”)
The output load consists of a capacitor (CL) and two resistors (RL, RISO). RISO is used
to stabilize the amplifier when it drives a large capacitive load. RISO is a short circuit
(0Ω) when CL is small.
The non-inverting comparator provides two trip points which are at 0.8VDD and 0.2VDD.
(See Section Figure 2-4: “Non-Inverting Comparator Block.”)
The resistors that are part of an amplifier are placed in pin sockets which are labeled.
The op amps are bypassed by 0.1 µF capacitors and the single op amp U1 can have
either a PDIP-8 or SOIC-8 package.
• PDIP-8 packages are inserted into the DIP-8 socket to the right of the U1 label.
• SOIC-8 packages can be accommodated; see Section 2.4.3 “Amplifier
Modifications Using 8-Pin SOIC Op Amps”.
The (surface mount) test points for power supply, ground, input signal and output signal
allow lab equipment to be connected to the board. The MCP6XXX Amplifier Evaluation
Board 4 top view is shown in Figure 2-2.

2.3.2 Inverting Integrator
• It integrates and inverts a voltage with an integrating frequency ω =1/R1C1
(rad/s). Additional components control output clipping (wind-up) and initialization
of the integrating capacitor (C1). Refer to Figure 2-1.
• Figure 2-5 shows the circuit diagram for the inverting integrator block.

2.4.3 Amplifier Modifications Using 8-Pin SOIC Op Amps
There are two options available when using single op amps in SOIC-8 packages
(150 mil wide):
• Soldering onto the MCP6XXX Amplifier Evaluation Board 4, or
• Soldering it onto a separate board which is connected to the DIP-8 socket
Figure 2-10 shows a SOIC-8 op amp soldered onto the MCP6XXX Amplifier Evaluation
Board 4.
FIGURE 2-10: Op Amp in SOIC-8 package soldered onto MCP6XXX Amplifier
Evaluation Board 4.
Figure 2-11 shows a SOIC-8 op amp and a DIP-8 socket, soldered onto the 8-Pin
SOIC/MSOP/TSSOP/DIP Evaluation Board available from Microchip Technology Inc.
(order # SOIC8EV). The two interconnect strips on the bottom are Samtec part #
BBS-14-T-B or equivalent and are soldered into the through holes for the DIP-8 socket.
Figure 2-12 shows this board plugged into the MCP6XXX Amplifier Evaluation Board
4.
Note: The DIP-8 socket must be empty; only one op amp can be used at a time.
Solder an SOIC-8
Op Amp onto the
board
Note: Insert the interconnect strips into the DIP-8 socket on the MCP6XXX Ampli-
fier Evaluation Board 4. Place the SOIC8EV board on the top of the inter-
connect strips with the same pin orientation. Now solder the strips to the top
board; this procedure ensures correct alignment of the strips. Clip the pins
flush with the top surface of the SOIC8EV board, then solder the SOIC-8
op amp on the top.

TABLE B-2: BILL OF MATERIALS – UNPOPULATED PARTS (102-00154R1)
The BOM in Table B-3 corresponds to the collection of resistors, capacitorys, jumpers
and MCP6021 op amps that come in the Accessory Bag which is shipped in the
MCP6XXX Amplifier Evaluation Board 4 Kit. These components are placed in an
separate ESD bag. They support the circuit in Section 2.4.1 “Building the Amplifier”.
Customers need to provide the resistors and capacitors for more amplifier circuits.
