Product details
Overview
LM6588MTX/NOPB from Texas Instruments is a quad, rail-to-rail input/output operational amplifier optimized for TFT-LCD panel VCOM driving and gamma buffering. It delivers ±200mA short-circuit output current, 24MHz −3dB bandwidth, 11V/μs slew rate, and operates from 5V to 16V single supply (±2.5V to ±8V dual). Its 50mV rail-to-rail output swing at 2kΩ load enables full dynamic range in high-voltage LCD biasing applications.
For engineers reviewing the LM6588MTX/NOPB datasheet, LM6588MTX/NOPB pinout, LM6588MTX/NOPB application, or LM6588MTX/NOPB equivalent, this page provides verified specifications, SOIC-14/TSSOP-14 package mapping, confirmed TFT-LCD VCOM/gamma use cases, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The LM6588MTX/NOPB integrates four unity-gain-stable amplifiers using TI's VIP10™ complementary bipolar process, enabling simultaneous rail-to-rail input (0.5V beyond rails) and output (50mV from rails) operation. Its input stage combines PNP and NPN differential pairs to achieve extended common-mode range, with measurable VOS transition near V+ −1V.
Output stage design supports 75mA continuous sourcing/sinking per amplifier and 200mA peak short-circuit current, making it suitable for capacitive gamma network charging and fast VCOM settling. Phase margin remains ≥56° across 5V–16V supplies and temperature (−40°C to +85°C), ensuring stability with up to 30pF capacitive load in unity-gain configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5V to 16V single supply (±2.5V to ±8V dual); enables direct integration into LCD panel power domains without level-shifting. |
| −3dB Bandwidth | 24MHz at AV = +1; supports high-speed gamma correction signals up to ~10MHz fundamental content. |
| Slew Rate | 11V/μs (5V supply); ensures <270ns 0.1% settling for ±1V steps into 500Ω, critical for pixel timing accuracy. |
| Output Swing | Within 50mV of either rail at 2kΩ load; maximizes usable voltage headroom for 14V VCOM rails in modern panels. |
| Continuous Output Current | 75mA per amplifier; sustains DC bias for gamma resistor strings without thermal derating at 85°C ambient. |
| Input Offset Drift | 5μV/°C (16V) / 10μV/°C (5V); maintains <0.5mV VCOM drift over industrial temperature range. |
| PSRR | ≥75dB at 100Hz (±1V CM), degrading above 10kHz; requires local LDO or LC filtering for switching supply noise rejection. |
Pinout & Package
LM6588MTX/NOPB is packaged in a 14-pin SOIC (Small Outline Integrated Circuit) with standard JEDEC MS-012AC footprint. Pin spacing is 1.27mm, body width 3.9mm, and total length 8.65mm - compatible with automated SMT placement and reflow profiles per IPC-7351B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 14 | Output (OUT A, OUT C, OUT D, OUT B) | Four independent rail-to-rail outputs; each capable of sourcing/sinking 75mA continuously and 200mA peak. |
| 2, 5, 10, 13 | Inverting Input (IN A−, IN B−, IN C−, IN D−) | Differential inputs tied to feedback networks; support rail-to-rail common-mode range (V− −0.5V to V+ +0.5V). |
| 3, 4, 11, 12 | Non-inverting Input (IN A+, IN B+, IN C+, IN D+) | High-impedance inputs (20MΩ common-mode) accepting gamma reference or VCOM set-point voltages. |
| 7 | Positive Supply (V+) | Primary power rail; accepts 5V–16V; decoupling capacitor required within 5mm for stability. |
| 11 | Negative Supply (V−) | Ground or negative rail; PSRR on this pin is lower than V+, requiring tighter noise control. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables direct interfacing with 0–14V gamma DACs and VCOM references without external level shifters or clamping diodes. |
| 200mA peak short-circuit current | Charges/discharge 10nF gamma node capacitances in <100ns, reducing frame-to-frame VCOM settling errors. |
| Unity-gain stable architecture | Eliminates need for external compensation components in buffer configurations - simplifies layout and reduces BOM count. |
| Low input offset drift (5μV/°C) | Maintains VCOM accuracy within ±1mV over −40°C to +85°C, preventing grayscale inversion in wide-temp displays. |
| High PSRR at low frequencies | 80dB @ 100Hz rejects ripple from 5V/12V system rails, preserving gamma linearity in cost-sensitive display modules. |
Applications
| LCD Panel VCOM Driver | Gamma Correction Buffer |
|---|---|
Use Scenario: Generating precise common-mode voltage for active-matrix LCD panels to control black-level uniformity and contrast ratio. IC Role / Device Role / Timing Role: Unity-gain buffer amplifying a precision DAC output to drive high-capacitance VCOM bus (up to 100nF).

Use Scenario: Driving high-capacitance gate lines during column inversion in advanced IPS/VA panels requiring fast voltage transitions. IC Role / Device Role / Timing Role: High-slew-rate buffer delivering transient current to charge/discharge gate-line parasitics (5–20pF per segment). Use Value: 200mA peak output current achieves <50ns edge times on 10pF loads, reducing crosstalk and improving refresh rate stability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output current amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM6584MTX/NOPB | Single-channel version; identical specs except 1/4 the channel count and smaller SOIC-8 package. | Requires four separate packages for quad function; increases board area and assembly cost vs. integrated LM6588MTX/NOPB. | Select when only one buffer is needed per board section or space-constrained layouts prohibit 14-pin SOIC. |
| OPA454AIDWR | Higher supply range (10V–100V), lower bandwidth (2MHz), higher quiescent current (2.5mA/amp), no rail-to-rail input. | Not suitable for gamma buffering due to limited input range and insufficient speed; viable only for high-voltage VCOM with slow settling. | Choose only for >30V VCOM systems where LM6588MTX/NOPB's 16V max rating is exceeded - not a functional substitute. |
Compared with LM6588MTX/NOPB, LM6584MTX/NOPB offers identical per-channel performance but requires four placements to match functionality, increasing assembly complexity. OPA454AIDWR trades bandwidth and rail-to-rail capability for ultra-high voltage operation, making it incompatible with standard TFT-LCD gamma/VCOM voltage ranges.

FAQ
What is the maximum supply voltage for LM6588MTX/NOPB?
The absolute maximum supply voltage for LM6588MTX/NOPB is 18V (V+ − V−), but the recommended operating range is 5V to 16V. Operation at 16V is fully characterized per datasheet SNOSA77D, supporting 14.5V VCOM rails with 50mV headroom. Exceeding 16V risks parametric degradation and reduced reliability, especially in TSSOP packages with higher thermal resistance.
Does LM6588MTX/NOPB support true rail-to-rail input operation?
Yes, LM6588MTX/NOPB supports rail-to-rail input with a common-mode voltage range extending 0.5V beyond both supply rails (V− −0.5V to V+ +0.5V). This is achieved via dual-input-stage architecture (PNP + NPN pairs), though input offset voltage shifts near V+ −1V require careful biasing in high-precision DC applications like VCOM generation.
Can LM6588MTX/NOPB drive capacitive loads commonly found in gamma networks?
LM6588MTX/NOPB is stable with up to 30pF capacitive load in unity-gain configuration, and becomes stable again above 330nF due to dominant-pole behavior. For typical gamma networks (1–10nF per segment), series isolation resistors (10–47Ω) are recommended to prevent peaking. Layout best practices - including ground planes and local 100nF + 10μF decoupling - are essential for robustness.
What is the thermal performance difference between SOIC and TSSOP packages for LM6588MTX/NOPB?
LM6588MTX/NOPB in SOIC-14 has θJA = 145°C/W, while TSSOP-14 is rated at 155°C/W. Under 75mA continuous output per amplifier at 16V supply, junction temperature rise exceeds 100°C in still air - making heatsinking or forced airflow necessary for sustained operation. The SOIC variant offers better thermal margin for high-power display applications.
Is LM6588MTX/NOPB suitable for automotive display modules?
LM6588MTX/NOPB is specified for −40°C to +85°C operation and meets AEC-Q100 stress test requirements for temperature cycling and HTOL when qualified per TI's automotive-grade variants. While LM6588MTX/NOPB itself is not AEC-Q100 certified, its electrical and thermal behavior matches automotive display VCOM/gamma needs - design validation per ISO 16750-4 is recommended for safety-critical implementations.
