DESCRIPTION
The DEM-OPA628 evaluation fixtures are
preassembled printed circuit boards designed for a
quick and easy evaluation of the OPA628 in a variety
of gain configurations. Burr-Brown offers one board
for the SOIC version of the OPA628 (AU model) and
a second one for the DIP package (AP model).
ceramic chip capacitors for local bypassing of all four
supply leads, are used to maintain the low harmonic
distortion the OPA628. The demonstration boards are
designed for use of surface-mount resistors to keep the
parasitic capacitance as low as possible by showing a
layout for multiple circuit configuration.
The use of the demoboards is recommended to evalu-
ate the performance of the OPA628. The optimized
and flexible layout provides the user with a selection
of various non-inverting and inverting gain configura-
tions. A combination of dipped tantalum capacitors to
bypass the power supplies at the board level, and
The fixture requires a bipolar ±5V power supply.
Separate power supply paths are used for the input-
stage and the output-stage supply. This approach mini-
mizes the coupling of non-linear output stage currents
into the input gain stages.
