LM358AP

LM358AP Description

The LM358AP from Texas Instruments is a general-purpose dual operational amplifier housed in an 8-pin DIP package. Designed for low-power, wide-voltage-range applications, it operates from 3V to 30V and features a low supply current of 500µA per channel, making it ideal for battery-powered systems. With a gain bandwidth product of 700 kHz and a slew rate of 0.3V/µs, it balances performance and efficiency for DC amplification, filtering, and signal conditioning. The device exhibits low input bias current (15 nA) and moderate input offset voltage (2 mV), ensuring stable operation in precision circuits. Its ROHS3 compliance and REACH-unaffected status make it suitable for environmentally conscious designs.
