Product details

These specs place it in the slow-to-moderate speed tier — adequate for filtering, sensor conditioning, and level-shifting below 100 kHz, but not for fast ADC drivers or video buffers.

3 V to 26 V supply — single-rail flexibility across industrial and automotive rails

The supply span covers 3 V minimum to 26 V maximum, so this op-amp runs directly off a 5 V logic rail, a 12 V automotive battery, or a 24 V industrial supply without a separate regulator. Each of the two channels draws 500 µA supply current, keeping the total quiescent draw under 1 mA for the whole package — a fit for loop-powered transmitters and battery-backed sensor nodes.

Obsolete — plan your BOM around surplus or a replacement

The base product LM2904 family remains widely available in other package and temperature variants (e.g. LM2904DR, LM2904P) — check the pin-compatible SOIC-8 options from TI or second-source equivalents from STMicroelectronics (LM2904DT) and On Semiconductor (LM2904DMR2G).

40 mA output drive per channel — enough for modest loads

Each amplifier can source or sink 40 mA. That drives a typical 5 V relay coil through a transistor, biases an LED indicator, or charges the sample-and-hold cap on a successive-approximation ADC. For heavier loads — solenoids, motors, or long cables — buffer the output with a discrete transistor stage.

Frequently asked questions

Where can I buy LM2904DRE4?

The LM2904DRE4 is obsolete and no longer in factory production. We source it through independent distribution and surplus channels.

What is the replacement for LM2904DRE4?

Texas Instruments has not published a direct successor for the LM2904DRE4 suffix. The base LM2904 family is still active in other package options (SOIC-8, DIP-8) and temperature grades. Pin-compatible alternatives include the LM2904DR (TI, same SOIC-8 footprint) or second-source parts like the STMicroelectronics LM2904DT or On Semiconductor LM2904DMR2G. Confirm the operating temperature range and supply voltage match your design before substituting.

Is LM2904DRE4 obsolete?

Yes, Texas Instruments lists the LM2904DRE4 as obsolete. Plan your BOM around surplus stock or a pin-compatible alternative from the LM2904 family.

Does LM2904DRE4 have an equivalent from other manufacturers?

Yes. The LM2904 is a standard dual op-amp second-sourced by multiple manufacturers. STMicroelectronics offers the LM2904DT (SOIC-8), and On Semiconductor lists the LM2904DMR2G. Verify pin-compatibility and temperature range against your design before substituting.
