CA3290A Features

* MOSFET Input Stage - Very High Input Impedance (ZIN) . . . . . . . . 1.7TΩ (Typ) - Very Low Input Current at V+ = 5V . . . . . . . 3.5pA (Typ) - Wide Common Mode Input Voltage Range (VICR) Can Be Swung 1.5V (Typ) Below Negative Supply Voltage Rail - Virtually Eliminates Errors Due to Flow

CA3290A General Description

The Basic Comparator Figure 4 shows the basic circuit diagram for one of the two comparators in the CA3290. It is generically similar to the industry type “139” comparators, with PMOS transistors replacing PNP transistors as input stage elements. Transistors Q1 through Q4 comprise the differential i.
