DESCRIPTION
The DEM-OPA65x AND DEM-OPA265x evaluation
fixtures are pre-assembled printed circuit boards designed to provide an optimized environment when
evaluating the wideband operational amplifiers of the
OPA65x series. The DEM-OPA65x is used for the
single op amps, where the DEM-OPA265x is designed
for dual op amps. A variety of different op amps can
be evaluated with the same board. For example the
voltage-feedback op amp OPA650/OPA651 or the
current-feedback op amp OPA658. Similarly for the
duals, the OPA2650 or the OPA2658 will fit on the
DEM-OPA265x demonstration board. Since the boards
are universal, the actual operational amplifier is not
included with the evaluation board. Boards are available for both package types, the DIP and the SOIC
package.

These demonstration boards have surface-mount resistors and ceramic bypass capacitors soldered on the
board. A collection of gain setting resistors is included
with the board. The feedback resistor is placed directly
between the input and the output pins. This is necessary to achieve the maximum bandwidth. The power
supply bypass capacitors consist of a tantalum and a
ceramic chip capacitor pair on each of the power
supplies. They are placed directly at the pins to maintain low harmonic distortion. For more detailed information on the operational amplifiers, refer to the
individual datasheets.
The demoboards have been designed to support a
variety of different circuit configurations. Also included are resistors for termination and isolation of
load capacitance. Slight degradation of the ac-performance is the tradeoff. However, the number of required components depends on the selected configuration.
