LM324 overview
LM324 is a component documented by NXP Semiconductors. The PDF description identifies it as "Low power quad op amps 1995 Nov 27." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- UNIQUE FEATURES In the linear mode, the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from only a single power supply voltage.
- The unity gain crossover frequency and the input bias current are temperature-compensated.
- Internally frequency-compensated for unity gain Large DC voltage gain: 100dB Wide bandwidth (unity gain): 1MHz (temperature-compensated) Wide power supply range Single supply: 3VDC to 30VDC or dual supplies: ±1.5VDC to ±15VDC Very low supp.
- Pin Configuration** DESCRIPTION TEMPERATURE RANGE ORDER CODE DWG # 14-Pin Plastic Dual In-Line Package (DIP) -55°C to +125°C LM124N SOT27-1 14-Pin Ceramic Dual In-Line Package (CERDIP) -55°C to +125°C LM124F 0581B 14-Pin Plastic Dual In-Li.
- Derate above 25°C at the following rates: F package at 9.5mW/°C N package at 11.4mW/°C D package at 8.3mW/°C 2.
- The maximum output current is approximately 40mA, independent of the magnitude of VCC .
- At values of supply voltage in excess of +15VDC continuous short-circuits can exceed the power dissipation ratings and cause eventual destruction.

Engineering review checklist
- Verify supply range, input common-mode range and output swing at the required load.
- Check offset, bias current, noise, bandwidth, slew rate and stability for the intended feedback network.
- Review supply decoupling, source impedance, capacitive-load behavior and thermal limits in the final layout.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
