Appendix A. Schematics and Layouts
A.1 INTRODUCTION
This appendix contains the schematics and layouts for the MCP6V01 Input Offset
Demo Board.
The Gerber files for this board are available on the Microchip website
(www.microchip.com) and are contained in the “00227R3_Gerbers.zip” zip file .
A.2 SCHEMATIC
See below the circuit diagram. On the left is the DUT (U1), which produces the common
mode voltage plus the DUT’s input offset (V
OS
) times a gain. In the middle is the
difference amplifier that amplifies and level shifts the DUT’s output minus the
mid-supply reference voltage. On the top right is the mid-supply reference (V
DD
/2) and
buffer. On the middle right is the common mode voltage reference (VCM) with buffer.
On the bottom are the supply bypass capacitors and filter resistors.
