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. A SPICE model using
MicroSim Corporation’s PSpice is available for the OPA620.
This simulation model is available through the Burr-Brown
web site at www.burr-brown.com or by contacting the Burr-
Brown Applications Department.
RELIABILITY DATA
Extensive reliability testing has been performed on the
OPA620. Accelerated life testing (2000 hours) at maximum
operating temperature was used to calculate MTTF at an
ambient temperature of 25
°
C. These test results yield MTTF
of: Cerdip package = 1.31E+9 Hours, Plastic DIP = 5.02E+7
Hours, and SO-8 = 2.94E+7 Hours. Additional tests such as
PCT have also been performed. Reliability reports are avail-
able upon request for each of the package options offered.
DEMONSTRATION BOARDS
Demonstration boards are available to speed protyping. The
8-pin DIP packaged parts may be evaluated using the DEM-
OPA65XP board while the SO-8 packaged part may be
evaluated using the DEM-OPA65XU board. Both of these
boards come partially assembled from your local distributor
(the external resistors and the amplifier are not included).
