CONNECTION
These demonstration boards have surface-mount resis-
tors 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 neces-
sary 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 main-
tain low harmonic distortion. For more detailed infor-
mation on the operational amplifiers, refer to the
individual datasheets.
DESCRIPTION
The DEM-OPA65x AND DEM-OPA265x evaluation
fixtures are pre-assembled printed circuit boards de-
signed 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 avail-
able for both package types, the DIP and the SOIC
package.
The demoboards have been designed to support a
variety of different circuit configurations. Also in-
cluded are resistors for termination and isolation of
load capacitance. Slight degradation of the ac-perfor-
mance is the tradeoff. However, the number of re-
quired components depends on the selected configura-
tion.
