MOTOROLA MC3405P

Order this document by MC3405/D
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.
