“Typical”—what does it mean in a data sheet specification?
Bruce Trump
Designers sometimes find op amp data sheet specifications perplexing
because not all performance characteristics have minimum or maximum
specifications. You must occasionally rely on “typical” values in the
specification table or typical performance graphs. But what does typical
mean? How much can it vary?
There are no easy answers and it depends on the specification. Here are
some guidelines on three characteristics which seem to get frequent
questions:
Bandwidth—The gain-bandwidth product (GBW) of an op amp is primarily
controlled by the current in the input stage and the on-chip capacitance
values. The variance of these two variables could mean that GBW could v
