Op-Amps — Operational Amplifier ICs

About

Operational Amplifier ICs — Single, Dual & Quad Op-Amps Operational amplifiers (op-amps) are the most versatile analog ICs ever made — a single op-amp can amplify, filter, compare, integrate, differentiate, or buffer any analog signal. This collection covers the complete range of general-purpose and audio op-amps, from the classic UA741 (the original op-amp, ideal for education) to high-performance audio op-amps like the NE5532 and NJM4580 used in professional audio equipment. Available in DIP (through-hole) and SOP (SMD) packages. General-Purpose Op-Amps UA741 / LM741C: Single, 1MHz GBW, ±15V — the original op-amp, ideal for electronics education and legacy repair LM358 / AS358M: Dual, single-supply 3V–32V, input to GND — most popular op-amp for battery-powered circuits and sensor amplification LM324N / LM224: Quad, single-supply 3V–32V — four op-amps in one package for multi-channel signal conditioning JFET Op-Amps (Low Noise, High Slew Rate) TL072 / TL082: Dual JFET, 3MHz GBW, 13V/μs — the standard audio op-amp for guitar effects, synthesizers, and active filters TL074 / TL084: Quad JFET, 3MHz GBW — four JFET channels for audio mixing and multi-stage filter banks TL064: Quad JFET, low-power — battery-powered audio circuits Audio Op-Amps (High Performance) NE5532: Dual, 10MHz GBW, 9nV/√Hz noise — the industry standard for professional audio preamplifiers NJM4580 / NJM4560: Dual JRC audio op-amps — found in CD players, DACs, and headphone amplifiers NJM4562 / NJM4585: High-performance JRC audio op-amps for DAC output buffering and headphone driving Audio Power Amplifier ICs LM386: 0.25W–1W, 4V–12V — portable speaker driver for Arduino and battery-powered audio 8002A / MD8002A: 3W BTL, 5V — compact speaker driver for USB-powered and IoT audio Op-Amp Selection Guide Education / legacy repair: UA741, LM741C Battery-powered / sensor circuits: LM358, LM324 (single-supply, input to GND) Audio / guitar effects / synthesizers: TL072, TL074, NE5532 Professional audio /
