MCP6XXX Amplifier Evaluation Board 4 User’s Guide
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 (C
) and two resistors (R
, R
). R
is used

to stabilize the amplifier when it drives a large capacitive load. R
is a short circuit

The non-inverting comparator provides two trip points which are at 0.8V
and 0.2V
.

(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.
