It is the tape-and-reel variant of the industry-standard LM324, offering four independent op-amps in a single 3.90 mm-wide SOIC body. Each of the four amplifiers delivers a 1.3 MHz gain-bandwidth product with a 0.4 V/µs slew rate, drawing 1.5 mA total supply current. The supply span runs from 3 V to 30 V, making it a single-supply part that also handles split rails. This means STMicroelectronics has flagged the part for eventual discontinuation — it is still available for existing BOM lines but should not be selected for new product introductions. For a production BOM already using the LM324DT, the NRND status means the window for last-time-buy planning is open. ## 14-SOIC footprint and temperature grade The package is a 14-SOIC (0.154-inch body width, 3.90 mm width), supplier device package 14-SO. Surface-mount only — no DIP variant here. ## Where the LM324DT fits and where it does not The 1.3 MHz GBP and 0.4 V/µs slew rate place this squarely in the general-purpose signal-conditioning class — sensor buffers, active filters below 100 kHz, DC level shifting, and comparator duty. It is not a high-speed or precision part; the 20 nA input bias and 2 mV offset are typical for this class, not competitive with precision op-amps.","metaTitle":"STMicroelectronics LM324DT Op-Amp, 1.3 MHz, 14-SOIC","metaDescription":"STMicroelectronics LM324DT quad general-purpose op-amp. 1.3 MHz GBP, 0.4 V/µs slew rate, 3 V to 30 V supply.
