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.
