TS321:Single LM324, LM358 enhanced version in sot23-5 package

The TS321 device is intended for cost-sensitive applications where space-saving is of great importance. This bipolar operational amplifier (op amp) offers the benefits of a reduced component size (SOT23-5 package) with specifications that match (or are better than) industry standard devices (such as the popular LM358A, LM324, and other similar devices). The TS321 device has an input common mode range (Vicm) that includes ground and therefore can be employed in single supply applications.
