TS321
DESCRIPTION
The TS321 is intended for cost sensitive applications where space saving is of great importance.
This bipolar Op-Amp offers the benefits of a reduced component size (SOT23-5package), with
specificationsthat match(orbetter)industrystandard devices (like the popular LM358A, LM324,
etc.).TheTS321hasaninputcommonmoderange
(Vicm) that includes ground, thereforecan beemployed in singlesupplyapplications.
