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.

The 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
