SPICE MODELS
Computer simulation 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. SPICE models using MicroSim
Corporation’s PSpice are available for the OPA644. Con-
tract Burr-Brown applications departments to receive a SPICE
Diskette.
DEMONSTRATION BOARDS
Demonstration boards to speed prototyping are available.
Refer to the DEM-OPA64X data sheet for details.
