DEM-OPA64x
EVALUATION FIXTURES
FEATURES
● SOIC AND DIP VERSIONS
DESCRIPTION
The DEM-OPA64x evaluation fixtures are fully as-
sembled printed circuit boards, except for the gain
setting resistors, which are included. There are six
different layouts—three for SOICs and three for DIPs.
The three layouts are optimized for different circuits,
which include a voltage follower, an inverting and a
non-inverting configuration.
● SURFACE MOUNT COMPONENTS
FOR OPTIMUM PERFORMANCE
● SMA INPUT AND OUTPUT JACKS
FOR MAXIMUM FREQUENCY RESPONSE
● 2.5" X 2.5" DIMENSIONS
● DIP WITH PIN SOCKETS
These demonstration boards are used to evaluate the
Burr-Brown OPA64x series of operational amplifiers.
Operational amplifiers are not included with the DEM-
OPA64x. These demonstration boards incorporate
surface-mount resistors and surface-mount ceramic
bypass capacitors. The feedback resistor is placed
directly between the input and output pins. This is
necessary to achieve greater than 500MHz bandwidth
performance. The size of the circuit traces and feed-
throughs are minimized to reduce parasitic capaci-
tance, and separate bypass capacitors are placed
directly at each of the four power pins to maintain low
harmonic distortion.
● UNIVERSAL POWER SUPPLY
CONNECTIONS
● INPUT AND OUTPUT TERMINATION
INCLUDED
APPLICATIONS
● EVALUATE OPA64xU (SOIC) AND
OPA64xP (DIP) PERFORMANCE
● EVALUATE HIGH-FREQUENCY,
TWO LAYER PCB LAYOUT
The fixture requires a bipolar ±5V power supply.
Separate power supply paths are required for each

power pin to achieve low even-order harmonic distortion.
This approach minimizes non-linear output stage currents
coupling into the input gain stages. The orientation of the
power traces and the ceramic bypass capacitors have been
empirically determined to give the best harmonic distortion.
The connection from the top side of the board to the bottom
was made as short as possible. Wide power supply traces are
recommended to reduce series impedance at high frequen-
cies.

Solid ground planes are used on both sides of the board and
are connected solidly together. The ground plane is removed
around the feedback resistor and signal paths to reduce
parasitic capacitance and ground plane noise coupling.
