Product details

Dual op-amp for high-temp signal conditioning

It delivers a 1.1 MHz gain bandwidth product and a 0.6 V/µs slew rate, making it suitable for sensor signal buffering, active filtering, and control-loop conditioning in systems where the junction temperature reaches 150°C.

Each channel sources or sinks 40 mA, enough to drive an ADC input, a comparator, or a small relay coil through a transistor buffer. Input bias current is 20 nA typical, and input offset voltage is 2 mV — adequate for DC-accurate sensing in motor drives, battery monitors, and pressure-transducer interfaces.

Frequently asked questions

What is the replacement for LM2904WHD?

No official replacement part is listed on the STMicroelectronics record for the LM2904WHD. A functionally similar dual op-amp in the same family, such as the LM2904 series variants, may be considered, but pin-compatibility and temperature grade should be verified against the original BOM requirements.
