MINI ANALOG SERIES
LOW INPUT OFFSET VOLTAGE CMOS OPERATIONAL AMPLIFIER
S-89713B Series
The mini-analog series is a group of ICs that incorporate a general
purpose analog circuit in a small package.
The S-89713B Series is an auto-zero operation, zero-drift operational
amplifier that has I/O of low input offset voltage and Rail-to-Rail
*1
. This
IC is suitable for applications requiring less offset voltage.
The S-89713B Series is dual operational amplifier (with 2 circuits).
*1.
