MC3405
Dual Operational Amplifier
and Dual Comparator
The MC3405 contains two differential–input operational amplifiers and
two comparators, each set capable of single supply operation. This
operational amplifier–comparator circuit fulfills its applications as a general
purpose product for automotive and consumer circuits as well as an
industrial building block.
www.DataSheet4U.cTohme MC3405 is specified over the commercial operating temperature
range of 0° to +70°C.
Operational Amplifier Equivalent in Performance to MC3403
Comparator Similar in Performance to LM339
Single Supply Operation: 3.0 V to 36 V
Split Supply Operation: ±1.5 V to ±18 V
Low Supply Current Drain
Operational Amplifier is Internally Frequency Compensated
Comparator TTL and CMOS Compatible
