Operational Amplifiers Series
Ground Sense Low Power
General Purpose Operational Amplifiers
LMR321G, LMR358xxx, LMR324xxx
●General Description
LMR321, LMR358 and LMR324 are single, dual and
quad low voltage operational amplifier with output full
swing.

solutions for applications where low supply current
consumption and low voltage operation.
●Features
Operable with low voltage
Input Ground Sense, Output Full Swing
High open loop voltage gain
Low supply current
Low input offset voltage

*11 Absolute value
*12 Full range: LMR321: Ta=-40℃ to +85℃
*13 Under the high temperature environment, consider the power dissipation of IC when selecting the output current.
When the terminal short circuits are continuously output, the output current is reduced to climb to the temperature inside IC.
