Overview
The LM258AMDREP is a high-reliability, dual operational amplifier produced by Texas Instruments. This component is part of the LM258A series and is designed for operation in harsh environments. It consists of two independent, high-gain, frequency-compensated operational amplifiers that can operate from a single supply over a wide range of voltages (3 V to 30 V) or from dual supplies (±1.5 V to ±15 V). The device is particularly suited for applications requiring extended temperature performance, ranging from -55°C to 125°C.
