LM324N Quad Operational Amplifier IC DIP-14 – Pack of 5

LM324N Quad Operational Amplifier IC — DIP-14 (5-Pack)

The LM324N contains four independent, high-gain operational amplifiers in a single DIP-14 package. Designed for single-supply operation from 3V to 32V (or ±1.5V–16V dual supply), it is one of the most widely used op-amps in analog circuit design — from comparators and filters to signal conditioning and oscillators.

Why Choose LM324N?

• Single-Supply Operation — Input common-mode range includes ground; works from a single 5V or 12V rail
• Quad Package — 4 op-amps in one DIP-14 IC reduces component count and board space
• Ultra-Low Power — 1.4mA total for all 4 amplifiers; ideal for battery-powered designs
• Wide Supply Range — 3V–32V covers virtually all common supply voltages
• Industry Standard — Pin-compatible with LM2902, MC3403, TL084 (JFET input variant)

Typical Applications

• Voltage comparator circuits (with or without hysteresis)
• Active low-pass, high-pass, and band-pass filters
• Transimpedance amplifier for photodiode current sensing
• Summing amplifier for audio mixing
• Precision rectifier and peak detector
• Oscillator and waveform generator circuits
• Sensor signal conditioning (temperature, pressure, light)

LM324 vs LM358 vs LM741

IC	Channels	Single Supply	Package

LM358N	2	✅ Yes (3–32V)	DIP-8
LM741	1	❌ Dual only	DIP-8

FAQ

Q: Can LM324N output rail-to-rail?
A: No — output swings to within ~1.5V of VCC. For true rail-to-rail output, use LMV324 or MCP6004.

Q: Is LM324N suitable for audio applications?
A: For low-frequency audio (below 10kHz) yes. The 1MHz GBW limits high-frequency performance. Use NE5532 or TL072 for audio-grade applications.
