CA3290AE [INTERSIL]

The CA3290A and CA3290 types consist of a dual voltage comparator on a single monolithic chip. The common mode input voltage range includes ground even when operated from a single supply. The low supply current drain makes these comparators suitable for battery operation; their extremely low input currents allow their use in applications that employ sensors with extremely high source impedances. Key features include MOSFET Input Stage, Very High Input Impedance (Z IN) 1.7T (Typ), Very Low Input Current at V+ = 5V 3.5pA (Typ), Wide Common Mode Input Voltage Range (V ICR) Can Be Swung 1.5V (Typ) Below Negative Supply Voltage Rail, Virtually Eliminates Errors Due to Flow of Input Currents, and Output Voltage Compatible with TTL, DTL, ECL, MOS, and CMOS Logic Systems in Most Applications.
