The LM148, LM248, and LM348 are quadruple, independent, high-gain, internally compensated operational amplifiers designed to have operating characteristics similar to the µA741. These amplifiers exhibit low supply-current drain and input bias and offset currents that are much less than those of the µA741.

CIRCUIT060074 — High-side current sensing with comparator circuit

This high-side, current sensing solution uses one comparator with a rail-to-rail input common mode range to create an over-current alert (OC-Alert) signal at the comparator output (COMP OUT) if the load current rises above 1 A. The OC-Alert signal in this implementation is active low. So when the (...)
