PHOTODIODE PGA PICTAIL™ DAUGHTER BOARD
The following name and assembly number are found on the Photodiode PGA PICtail™
Daughter Board’s Printed Circuit Board (PCB):
• MCP6SX2DM-PICTLPD
• 102-00029
This PCB goes by the following titles:
• Photodiode PGA PICtail™ Daughter Board
• MCP6SX2 Photodiode-PGA Demo Board
This board supports the photodiode AN951, “Amplifying High-Impedance Sensors –
Photodiode Example” (DS00951). It uses the PNZ334 photodiode as a light detector.
Its output is conditioned by the MCP6001U op amp, which is set up as a
transimpedance amplifier. The output is then amplified (and buffered) by either the
MCP6S22 or the MCP6S92 Programmable Gain Amplifier (PGA).

The Photodiode PGA PICtail™ Daughter Board contains the analog circuitry
represented in Figure 1-1. Light incident to the photodiode is converted to current. The
op amp converts current to voltage (transimpedance amplifier). This voltage is sent to
the CH0 input of the PGA. The PGA gains and buffers this output, which is sent
off-board (V
makes it possible to control the PGA; its gain and input channel can be set as desired
from the software.
