Amplifiers — Manufactured by onsemi

The LM358/LM2904 series consists of two independent, high-gain, internally frequency-compensated operational amplifiers designed to operate from a single power supply over a wide range of voltages. These amplifiers are particularly suited for applications where the common-mode input voltage range includes ground, eliminating the need for external biasing in many circuits. They feature low power consumption and stable operation across a broad temperature range, making them an industry-standard choice for general-purpose analog signal processing. The device is robust, offering short-circuit protection and the flexibility to operate from either single or split power supplies.

❓ Frequently Asked Questions

Can this operational amplifier operate from a single 5V supply?

Yes, the LM358/LM2904 series is specifically designed for single-supply operation and can operate with a supply as low as 3.0V.

What is the main difference between the LM358 and the LM2904?

The primary difference is the operating temperature range; the LM2904 is rated for a wider range (-40°C to +105°C) suitable for industrial and automotive environments, whereas the LM358 is typically rated for commercial use (0°C to +70°C).

Does the input range include ground?

Yes, one of the distinct advantages of this amplifier is that its common-mode input voltage range includes the negative supply (ground), which simplifies biasing in single-supply applications.
