Op Amp Parameters
What parameters are normally applied to op amps?
There are usually three main sections of electrical tables in op amp data sheets. The
absolute maximum ratings table and the recommended operating conditions table list
constrains placed upon the circuit in which the part will be installed. Electrical
characteristics tables detail device performance.
Absolute maximum ratings are those limits beyond which the life of individual devices may
be impaired and are never to be exceeded in service or testing. Limits, by definition, are
maximum ratings, so if double-ended limits are specified, the term will be defined as a
range (e.g., operating temperature range).
Recommended operating conditions have a similarity to maximum ratings in that operation
outside the stated limits could cause unsatisfactory performance. Recommended operating
conditions, however, do not carry the implication of device damage if they are exceeded.
Electrical characteristics are measurable electrical properties of a device inherent in its
design. They are used to predict the performance of the device as an element of an electrical
circuit. The measurements that appear in the electrical characteristics tables are
based on the device being operated within the recommended operating conditions.
