LM2904DR in LM358 / LM324 Op-Amps Family
The LM2904DR is a dual-channel, high-gain general-purpose operational amplifier designed by Texas Instruments and other major manufacturers. A part of the industry-standard LM358/LM324 lineage, it is engineered to operate from a single power supply across a wide voltage range or from split supplies. Known for its cost-effectiveness and versatility, this IC is a staple in low-frequency analog signal processing, sensor conditioning, and basic mathematical operations in both industrial and consumer electronics environments.
Variants in This Sub-Family
Variants within the LM2904 family primarily differ by operating temperature range, packaging, and specific qualification standards. For instance, the LM2904-Q1 is AEC-Q100 qualified for automotive applications, while the LM2904B offers improved specifications like lower offset voltage and higher supply voltage (up to 40V). Packaging options range from SOIC and TSSOP to smaller VSSOP footprints, allowing designers to balance PCB space constraints against thermal dissipation requirements.
