TS321

Low Power Single Operational Amplifier

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 (SOT23-5

package), with specifications that match (or are

better) industry standard devices (like the popular

LM358A, LM324, etc.). The TS321 has an input

and therefore can be employed in single supply

applications.
