MCP6S22 PGA PICtail™ Demo Board User’s Guide

When the MCP6S22 PGA PICtail Demo Board is connected to the PICkit 1 Flash
Starter Kit, the gain and channel configuration DIP switch (S
button switch (S
on-board USB PICmicro microcontroller (PIC16C745) are configured as
high-impedance inputs. This prevents a potential serial bus conflict if the
user-developed firmware for the MCP6S22 PGA PICtail Demo Board and the PICmicro
microcontroller on the PGA demo board try to access the PGA at the same time.

Soldering pads are provided on this MCP6S22 Demo Board for SMA connectors and
prototype circuit development. These pads are different from the traditional
through-hole prototype area. In order to measure optimum PGA performance, it is
essential that the analog circuit have a solid ground plane. Therefore, this demo board
is developed on a four-layer board with a minimum number of through-holes through
the analog ground plane. Because of this, the pins may need to be bent accordingly for
soldering purposes.
