Quad op-amp with 150°C rating — the temperature-driven choice
The STMicroelectronics LM2902HDT is a quad general-purpose operational amplifier in a 14-SOIC package. The 1.3 MHz gain-bandwidth product and 0.4 V/µs slew rate are typical for a general-purpose op-amp — adequate for DC-level shifting, signal conditioning below 30 kHz, and low-speed filter stages. The 3 V to 30 V supply span covers single 5 V logic rails up to 24 V industrial buses without a separate regulator.
Pin-compatible alternatives and the LM324 family
The LM2902HDT shares the same quad op-amp pinout as the industry-standard LM324 family. If your application does not require the full 150°C ceiling, a standard LM2902 or LM324 variant in the same 14-SOIC footprint is a drop-in replacement for new-design qualification — but no official cross-reference is recorded for the LM2902HDT specifically.
