Features & Applications
The TS321ILT 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 (SOT-23-5 package) with specifications that match (or are better than) industry standard devices (such as the popular LM358A, LM324, and as such).

The TS321 has an input common-mode range (Vicm) that includes ground and therefore can be employed in single-supply applications.


  • Large output voltage swing: 0 to 3.5 V min. (VCC = 5 V)
