Product Overview
The LM324DR is a Texas Instruments Signal_Chain quad operational amplifier in the LM324 family. It integrates four amplifiers in one D SOIC 14-pin package, with body dimensions of 8.65 mm × 6 mm. The package pinout assigns VCC+ to pin 4 and VCC− to pin 11, with the negative supply pin also used as ground for single-supply operation.
Recommended operation covers a 3 V to 30 V supply range and a 0 V to VCC - 2 V common-mode input voltage range. The recommended operating free-air temperature range is 0°C to 70°C. Absolute maximum ratings include 32 V supply voltage, ±32 V differential input voltage, -0.3 V to 32 V input voltage range, 150°C maximum virtual junction temperature, and -65°C to 150°C storage temperature.
For board and assembly review, the D SOIC thermal data includes 99.3°C/W RθJA, 60.4°C/W RθJC(top), 57.5°C/W RθJB, 19.8°C/W ψJT, and 57.0°C/W ψJB. The quad structure supports multi-channel signal-chain functions where four operational amplifier channels are required in a single 14-pin SOIC footprint.

Procurement Notes
When requesting a quote for LM324DR, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
FAQ
How many amplifiers are integrated in LM324DR?
LM324DR is a quad operational amplifier, so it includes four amplifier channels in one LM324 family device. The D SOIC package pinout lists separate input and output pins for amplifier channels 1 through 4.
What supply voltage range is recommended for LM324DR?
The recommended supply voltage range for LM324DR is 3 V to 30 V. The absolute maximum supply voltage rating is 32 V, which is a limit rating rather than the normal operating range.
Which package and pin count does LM324DR use?
LM324DR uses the D SOIC 14-pin package, with listed package dimensions of 8.65 mm × 6 mm. VCC+ is assigned to pin 4, and VCC− is assigned to pin 11.
What are the LM324DR input voltage limits?
The absolute maximum input voltage range for either input is -0.3 V to 32 V. The absolute maximum differential input voltage rating is ±32 V, measured for IN+ with respect to IN−.
