What the LM158 does
The LM158, LM258, LM358, and LM2904 are dual operational amplifiers designed for single or split supply operation. These devices span commercial, industrial, and military temperature grades with supply ranges from 3V to 32V. Key parameters include 0.7MHz unity gain bandwidth, 100dB open-loop gain, and 20nA typical input bias current. The family supports differential input voltages up to the maximum rated supply voltage. Engineers typically use these amplifiers in applications such as digital multimeters, temperature sensors, motor control circuits, and audio equipment like Blu-ray players and home theaters.
