Product details
Overview
LM833DR from Texas Instruments is a dual high-speed audio operational amplifier designed for preamplification and signal conditioning in HiFi, PCM, and RIAA phono stages. It delivers 7 V/μs slew rate, 16 MHz gain-bandwidth product, 0.002% THD at 20 Hz–20 kHz, ±14.6 V output swing (±15 V supply), and 4.5 nV/√Hz input voltage noise - enabling low-distortion, wide-dynamic-range analog audio paths.
For engineers reviewing the LM833DR datasheet, LM833DR pinout, LM833DR application, or LM833DR equivalent, this page provides verified specifications, SOIC-8 package layout, real-world audio use cases, and validated alternative op-amps for preamp, filter, and line-driver designs requiring low noise, high slew, and stable unity-gain operation.
Technical Context
The LM833DR implements two independent high-fidelity op-amp channels with fully differential input stages, rail-to-rail output capability limited by saturation margins (±14.6 V at ±15 V), and internal compensation optimized for unity-gain stability with capacitive loads up to 100 pF. Its architecture supports dual-supply operation from ±5 V to ±18 V and maintains >40° phase margin across temperature and load variations.
It features matched channel characteristics (e.g., <0.15 mV input offset voltage, <2 μV/°C drift), symmetrical sink/source short-circuit current (±29 mA), and excellent AC performance: 800 V/V open-loop gain at 20 kHz, –120 dB amp-to-amp isolation, and 120 kHz power bandwidth at ≤1% THD into 2 kΩ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±18 V - supports standard audio rails (±12 V, ±15 V) and enables flexible headroom design without external regulators. |
| Slew Rate | 7 V/μs - ensures faithful reproduction of fast transients (e.g., drum attacks, percussive peaks) without slew-induced distortion. |
| THD + N | 0.002% at 3 Vrms, 20 Hz–20 kHz - meets HiFi-grade audio fidelity requirements for preamp and line-stage applications. |
| Input Noise | 4.5 nV/√Hz at 1 kHz - enables low-noise microphone and phono preamplifier designs without requiring additional gain-stage optimization. |
| Output Swing | –14.6 V to +14.1 V (±15 V supply, RL = 10 kΩ) - delivers >28 VPP dynamic range, minimizing clipping risk in high-fidelity signal chains. |
| Gain Bandwidth | 16 MHz - supports stable unity-gain and moderate-gain configurations (e.g., AV = 10–100) with adequate phase margin. |
| Input Offset | 0.15 mV (typ), 3 mV (max, –40°C to 85°C) - reduces DC error in DC-coupled audio paths and minimizes audible "pop" on power-up. |
Pinout & Package
LM833DR is supplied in an 8-pin SOIC (Small Outline Integrated Circuit) package measuring 4.90 mm × 3.91 mm, with standard 1.27 mm pitch and gull-wing leads suitable for automated assembly and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1 (Pin 1) | Output 1 | First amplifier's buffered, low-impedance output node - drives downstream filters, tone controls, or power amplifiers. |
| IN1– (Pin 2) | Inverting Input 1 | High-impedance differential input for feedback network connection - sets closed-loop gain and frequency response. |
| IN1+ (Pin 3) | Noninverting Input 1 | High-impedance reference input - accepts audio source signals (e.g., phono cartridge, line-level inputs) with minimal loading. |
| VCC– (Pin 4) | Negative Supply | Ground-referenced negative rail connection - must be decoupled with ≥47 µF electrolytic + 0.1 µF ceramic for low-impedance return path. |
| IN2+ (Pin 5) | Noninverting Input 2 | Second amplifier's signal input - used for stereo channels, dual-filter paths, or cascaded gain stages (e.g., RIAA equalization). |
| IN2– (Pin 6) | Inverting Input 2 | Second amplifier's feedback node - enables independent configuration of second channel without crosstalk interference. |
| OUT2 (Pin 7) | Output 2 | Second amplifier's output - supports stereo preamp, balanced driver, or active crossover implementations. |
| VCC+ (Pin 8) | Positive Supply | Ground-referenced positive rail connection - requires local 0.1 µF ceramic + bulk 47 µF capacitor to suppress supply ripple and HF noise. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel matching | Channel-to-channel input offset voltage mismatch <0.5 mV - ensures consistent gain and DC bias across stereo or multi-path circuits. |
| Unity-gain stability | Stable with CL ≤100 pF and RL ≥2 kΩ - eliminates need for external compensation in most audio buffer and filter applications. |
| Low THD at full swing | 0.002% THD at 3 Vrms output - preserves harmonic integrity in critical preamp stages where distortion accumulates across multiple gain blocks. |
| Wide common-mode range | ±14 V input common-mode range (±15 V supply) - accommodates large-signal AC coupling and DC-biased sensor interfaces without clipping. |
| High open-loop AC gain | 800 V/V at 20 kHz - maintains loop gain for precise frequency shaping (e.g., RIAA equalization) even at upper-audio frequencies. |
Applications
| Microphone Preamplifier | RIAA Phono Equalizer |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual audio op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532DR | Higher input bias current (300 nA vs 750 nA), slightly lower slew rate (9 V/μs), identical THD (0.002%) and noise (5 nV/√Hz). | Better suited for high-source-impedance phono preamps due to lower bias current; wider supply range (±3 V to ±20 V). | Select NE5532DR when sourcing from high-Z cartridges or requiring extended supply flexibility; verify PCB layout for improved PSRR. |
| OPA2134PA | FET-input architecture (1 pA bias), lower noise (8 nV/√Hz), higher cost, 20 V/μs slew rate, but only 8 MHz GBW. | Preferred for ultra-low-bias applications (e.g., piezo sensors); less ideal for wideband RIAA or fast transient handling. | Choose OPA2134PA for DC-coupled, high-impedance sensor interfaces; avoid for high-frequency equalization where LM833DR's 16 MHz GBW is critical. |
Compared with NE5532DR and OPA2134PA, the LM833DR offers optimal balance of low noise, high slew, and unity-gain stability for cost-sensitive HiFi preamp and line-stage designs - delivering superior transient fidelity over OPA2134PA and better thermal stability than NE5532DR under sustained output conditions.

FAQ
What supply voltage range does the LM833DR support?
The LM833DR operates over ±5 V to ±18 V dual supplies, with recommended conditions of ±12 V or ±15 V for audio applications. Absolute maximum ratings allow ±18 V, but thermal dissipation must be managed at higher voltages. The LM833DR maintains specified performance across its full operating temperature range (–40°C to +85°C) within these limits.
Is the LM833DR unity-gain stable?
Yes, the LM833DR is internally compensated for unity-gain stability with resistive loads ≥2 kΩ and capacitive loads ≤100 pF. This allows direct use in non-inverting buffers, active filters, and gain-of-one line drivers without external compensation components - a key advantage over many general-purpose op-amps requiring external nulling networks.
How does the LM833DR compare to the NE5532 in audio performance?
The LM833DR matches the NE5532 in THD (0.002%), offers comparable noise (4.5 nV/√Hz vs 5 nV/√Hz), and provides higher gain-bandwidth (16 MHz vs 10 MHz). Its lower input offset voltage (0.15 mV vs 0.5 mV) improves DC accuracy in cascaded stages. Both are pin-compatible in SOIC-8, making LM833DR a drop-in upgrade for noise- and bandwidth-critical designs.
Can the LM833DR drive 600 Ω professional audio loads?
Yes - the LM833DR delivers ±10.7 V output swing into 600 Ω (at ±15 V supply) with <0.002% THD, supporting professional line-level standards. Its ±29 mA short-circuit current ensures robust drive capability, though continuous operation into 600 Ω requires attention to thermal derating per the SOIC package's 97°C/W junction-to-ambient rating.
What is the typical input bias current of the LM833DR?
The LM833DR exhibits 300 nA typical input bias current at 25°C (750 nA max over temperature), significantly lower than legacy bipolar op-amps like the LM741. This enables high-impedance feedback networks (e.g., >100 kΩ) in RIAA equalizers without introducing gain error or time-constant drift - a critical factor in precision audio filter design.
