DC417B - Demo Manual

DEMO MANUAL DC417B
Multi-Footprint
Single Op Amp Prototyping Boards
DESCRIPTION
The DC417B demo board set gives maximum flexibility for
prototyping single op amp circuits. This demo manual lists
which components to use for common op amp circuits
and an example is given for a standard pinout single op
amp circuit.
Design files for this circuit board are available at

OPERATING PRINCIPLES
The DC417B demo board comes as a two board set; one
board for DIP8, S8, DFN8, and MS8 packages and the
other board for SOT23-5 and SOT23-6 packages. Each
board is laid out such that most of the general op amp
circuits can be easily built. Both boards have decoupling
cap positions included.
Component positions are included for common circuit
configurations. Take your schematic and identify component positions on the board which correspond to the
components in the schematic. Air-wire other components
as needed, taking advantage of the exposed ground planes
as desired. Terminal posts at the sides of both boards give
easy access to power, ground, inputs, and outputs. Access
is provided to all IC pins. Pins 1, 5, and 8 are brought
out to terminals for easy access on the DIP8, S8, DFN8,
and MS8 board. Pin 5 is brought out to a terminal on the
SOT23-5 and SOT23-6 board. These pins are typically
used for offset adjustment, trimming VOS , or shutdown.
The layout includes positions for BNC connectors for both
inputs and outputs. Although component pads are marked
as C for capacitors and R for resistors, any component
that fits any footprint can be placed on the board.

CIRCUIT EXAMPLE
To build a noninverting amp using the DIP8/S8/MS8/DFN8
board use the R3 component position for the feedback
resistor and R11 for the gain set resistor. C6 and C2 are
the decoupling caps located close to the IC package and
C3 and C5 the bulk decoupling caps located next to the
power input terminals at the edge of the board. Jumper
wires or 0Ω resistors would be used for the R8 component
position on the input path to use the BNC connector J3,
or R8 and R13 to use input terminal TP11 and at R7 on
the output path to use BNC J2 or output terminal TP9 for
connection input and output signals.
