• Manufacturer: Burr-Brown

distortion, non-inverting amplifier operation. Order these
boards by the following part numbers from your local Burr-
Brown distributor:
DEM-OPA64XP-N for the OPA643P and OPA643PB (8-pin DIP package)
DEM-OPA64XU-N for the OPA643U and OPA643UB (8-pin SO package)
The SOT23-5 package version of the OPA643 may be
evaluated using a single unpopulated board used for numerous
SOT23-5 packaged amplifiers available from Burr-Brown.
This board is available from the Burr-Brown Literature
department as an unpopulated board attached to a descriptive
document. This board, the DEM-OPA6xxN, is available
free by requesting literature number MKT-348.

MACROMODELS AND APPLICATIONS SUPPORT
Computer simulation of circuit performance using SPICE is
often useful when analyzing the performance of analog
circuits and systems. This is particularly true for video and
RF amplifier circuits where parasitic capacitance and
inductance can have a major effect on circuit performance.
A SPICE model for the OPA643 is available through the
Burr-Brown Internet web page (http://www.burr-brown.com)
or as a disk from the Burr-Brown Applications department
(1-800-548-6132). The Application department is also
available for design assistance at this number. These models
do a good job of predicting small signal AC and transient
performance under a wide variety of operating conditions.
They do not do as well in predicting the harmonic distortion
or dG/dP characteristics. These models do not attempt to
distinguish among the various package types in their small
signal AC performance.
