The MC1458, C was designed for use as a summing amplifier, integrator,
or amplifier with operating characteristics as a function of the external
feedback components.

• No Frequency Compensation Required

• Short Circuit Protection

• Wide Common Mode and Differential V oltage Ranges

• Low Power Consumption

• No Latch–Up
