Product details
Overview
LM6584MAX/NOPB from Texas Instruments is a quad, rail-to-rail input/output operational amplifier optimized for TFT-LCD panel VCOM driving, gamma buffering, and repair amplification. It delivers ±310/−410mA peak output current, 24MHz −3dB bandwidth, and 11V/μs slew rate while operating from 5V to 13V supply. Its 0.5V beyond-rail input common-mode range and 50mV-from-rail output swing enable full dynamic range in single-supply LCD biasing applications.
For engineers reviewing the LM6584MAX/NOPB datasheet, LM6584MAX/NOPB pinout, LM6584MAX/NOPB application, or LM6584MAX/NOPB equivalent, key selection criteria include verified 75mA continuous output per channel, SOIC-14 package compatibility, −40°C to +85°C industrial temperature rating, and confirmed suitability for high-capacitive-load gamma buffer stages requiring fast settling (270ns, 0.1%) and low THD (−53dBc, 2nd harmonic).
Technical Context
The LM6584MAX/NOPB integrates four independent unity-gain-stable amplifiers using TI's VIP10 complementary bipolar process. Its dual-input-stage architecture-PNP pair for V− to ~1V below V+, NPN pair for ~1V below V+ to V+ +0.5V-enables true rail-to-rail input operation but introduces measurable VOS transition at the crossover point.
Output stage employs high-current bipolar transistors capable of sourcing/sinking up to 310/410mA peak, with thermal derating enforced by θJA = 145°C/W (SOIC) and strict junction temperature limits (TJ ≤ 150°C). Stability is maintained across 0–30pF capacitive loads in unity gain and remains robust up to 330nF at higher gains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5V to 13V - supports both single-supply (e.g., +12V) and split-supply (±2.5V to ±6.5V) LCD bias configurations |
| −3dB Bandwidth (AV = +1) | 24MHz - sufficient for gamma correction signal fidelity up to ~10MHz fundamental content in high-refresh panels |
| Slew Rate | 11V/μs - enables fast transient response during pixel voltage transitions without slew-induced distortion |
| Continuous Output Current | 75mA per amplifier - sustainable DC drive for VCOM line stabilization under typical panel leakage and capacitance |
| Input Common-Mode Range | V− −0.5V to V+ +0.5V - allows direct connection to digital logic references or mid-supply bias networks |
| Output Swing (RL = 2kΩ) | Within 50mV of either rail - maximizes usable voltage headroom for 12-bit gamma DAC interfaces |
| Settling Time (0.1%) | 270ns - meets timing budgets for multi-channel gamma calibration sequences in automated test equipment |
Pinout & Package
LM6584MAX/NOPB is housed in a 14-pin SOIC package (package code: D), with exposed pad not present. Pin assignments follow standard quad op-amp topology with independent inputs/outputs per channel and shared power rails.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Output A/B/C/D | Amplifier outputs - each drives dedicated VCOM segment or gamma tap; capable of 75mA continuous sink/source |
| 2, 6, 10, 12 | Inverting Input A/B/C/D | Negative feedback node - connected to resistive divider or DAC output in buffer configuration |
| 3, 7, 11, 14 | Non-inverting Input A/B/C/D | Reference input - accepts DC bias or AC-coupled video signal for repair amp function |
| 4 | V+ | Positive supply rail - must be decoupled with ≥1μF ceramic + 10μF tantalum near pin |
| 11 | V− | Negative supply or ground - low-impedance return path critical for stability under high-current transients |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM6582MX/NOPB | Dual-channel version; identical electrical specs per amplifier but half channel count | Requires two devices for quad-channel VCOM/gamma systems; increases board area and BOM count | Select when only two high-current buffers are needed or space-constrained designs favor dual-SOIC over quad-SOIC |
| OPA454AIDWR | Higher supply range (10–100V), lower bandwidth (2MHz), higher quiescent current (4.5mA/amp) | Over-specified for LCD biasing; better suited for piezo drivers or high-voltage industrial analog outputs | Choose only if system requires >13V operation or >100mA continuous output; not drop-in compatible due to pinout and bias differences |
Compared with LM6582MX/NOPB, LM6584MAX/NOPB reduces component count and interconnect complexity in quad-channel LCD biasing. Against OPA454AIDWR, it offers 12× higher bandwidth and 6× lower supply current at 13V, making it purpose-fit for cost-sensitive, power-constrained TFT display subsystems.

FAQ
What is the maximum continuous output current per channel for LM6584MAX/NOPB?
The LM6584MAX/NOPB provides 75mA continuous output current per amplifier under SOIC-14 package conditions at TA = 25°C. This rating assumes proper PCB thermal management and is derated at elevated ambient temperatures per the device's θJA = 145°C/W specification. Exceeding this current continuously risks junction temperature exceeding 150°C, triggering thermal protection or permanent damage.
Does LM6584MAX/NOPB support single-supply operation at 5V?
Yes, LM6584MAX/NOPB is fully specified for 5V single-supply operation. At VS = 5V, it delivers rail-to-rail input range (−0.2V to +5.2V), output swing within 150mV of rails (0.15V to 4.85V), 24MHz −3dB bandwidth, and 270ns 0.1% settling time. These parameters are validated in the 5V DC and AC Electrical Characteristics tables of the official datasheet (SNOSA44C).
What is the recommended decoupling strategy for LM6584MAX/NOPB?
TI recommends placing a 0.1μF ceramic capacitor and a 10μF tantalum (or low-ESR electrolytic) capacitor between V+ (pin 4) and V− (pin 11), located within 5mm of the SOIC package. Additional 100nF ceramics should be placed at each V+/V− pair if multiple supplies feed adjacent channels. Ground plane implementation is mandatory to suppress inductive coupling from 310mA peak output transients.
Can LM6584MAX/NOPB drive capacitive loads greater than 30pF?
Yes - LM6584MAX/NOPB remains stable with up to 30pF in unity-gain configuration, but becomes unconditionally stable again above ~330nF due to dominant-pole roll-off. For loads between 30pF and 330nF, phase margin degrades; TI recommends adding a small series resistor (10–50Ω) in the feedback path or using gain ≥ +2 to restore stability. This behavior is documented in Figure 15 (Stability vs. Capacitive Load).
Is LM6584MAX/NOPB pin-compatible with other TI quad op amps like LM324?
No, LM6584MAX/NOPB is not pin-compatible with LM324 or other legacy quad op amps. It uses a unique 14-pin SOIC pinout (D package) with V+ on pin 4 and V− on pin 11, whereas LM324 places V+ on pin 4 and V−/GND on pin 11 only in single-supply mode. Direct substitution would cause incorrect power routing and potential device damage. Always verify pin mapping against the LM6584MAX/NOPB connection diagram (Figure 2).
