Frequently Asked Questions
What are the key electrical specifications of the LM2904DR?
The LM2904DR features a dual voltage-feedback op-amp with a maximum bias current (IIB) of 0.25µA at 25°C, a minimum common-mode rejection ratio (CMRR) of 50dB (80dB typical), and is available in a Small Outline (SOIC) package. It supports a wide supply voltage range making it suitable for both single and dual supply designs.
What are the typical applications for the LM2904DR?
The LM2904DR is commonly used in active filter designs, signal conditioning for sensors, audio preamplification, voltage comparator circuits, and industrial instrumentation. Its dual-amplifier configuration and low bias current make it especially useful in high-impedance sensor interfaces and precision analog front-ends.
What package does the LM2904DR come in and what are the alternatives?
The LM2904DR is available in an SOIC (Small Outline Integrated Circuit) package, which is a standard surface-mount format offering reliable PCB mounting and good thermal performance. Compatible alternatives with similar pinouts include the LM358DR and TL072 series, though specific electrical parameters may differ.
How does the LM2904DR compare to the LM358?
The LM2904DR and LM358 are functionally similar dual general-purpose op-amps from Texas Instruments with comparable pinouts and supply voltage ranges. The LM2904DR is specified to operate over an extended temperature range and may offer slightly different bias current and CMRR characteristics, making it preferable in certain industrial temperature environments.
