MINI-ANALOG SERIES
CMOS SINGLE OPERATIONAL AMPLIFIER
S-8944XA Series
The mini-analog series is a family of standard analog circuits mounted in
ultra-small packages.
The S-8944XA series is a CMOS operational amplifier with a built-in
phase compensation circuit.
The S-8944XA series is suitable for applications in battery powered
compact portable devices due to its lower operation voltage and lower
current consumption compared to bipolar operational amplifiers.
