Overview
The LM258ADRG4 is a dual operational amplifier produced by Texas Instruments. It consists of two independent, high-gain frequency-compensated operational amplifiers designed to operate from a single supply or split supply over a wide range of voltages. This device is particularly useful in systems where a single supply voltage is available, and it can easily provide the required interface electronics without the need for additional ±5-V supplies.
