The LM158/LM258/LM358/LM2904 are low power dual operational amplifiers designed to operate from a single power supply system. The features include: operation from a single power supply; input common-mode voltage range includes ground; output voltage can swing to ground; unity gain cross frequency is temperature compensated; input bias current is temperature compensated.
This document provides a general description and unique characteristics for the LM158 series of low power dual operational amplifiers. These devices consist of two independent, high gain, internally frequency compensated op amps designed to operate from a single power supply over a wide voltage range, eliminating the need for dual supplies. Key advantages include the ability to sense signals near ground and swing the output to ground even when powered by a single supply, making them compatible with standard +5V digital systems.
| Large dc voltage gain | 100 dB |
|---|---|
| Unity gain bandwidth | 1 MHz |
| Single supply voltage range | 3V to 32V |
| Dual supply voltage range | +1.5V to +16V |
| Supply current drain | 500 µA |
| Input offset voltage | 2 mV |
| Output voltage swing (single supply) | 0V to V+ - 1.5V |
Yes, the LM158 series was designed specifically to operate from a single power supply over a wide range of voltages.
Yes, the output voltage can swing to ground even when operated from only a single power supply voltage.
The supply current drain is very low at 500 µA and is essentially independent of the supply voltage.
