Product details
Overview
LM6134AIMX from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-power, wide-supply, high-bandwidth applications. It delivers 10 MHz gain-bandwidth, 12 V/μs slew rate, and 360 μA/amp quiescent current at 5 V, operating from 2.7 V to 24 V. It supports battery-operated instrumentation and flat-panel display buffering with true rail-to-rail CMVR (−0.25 V to 5.25 V) and output swing.
For engineers reviewing the LM6134AIMX datasheet, LM6134AIMX pinout, LM6134AIMX application, or LM6134AIMX equivalent, key selection criteria include its 10 MHz GBW at ultra-low supply current, rail-to-rail I/O performance across 2.7–24 V, thermal stability in SOIC-14 packaging, and verified drive capability into capacitive LCD loads without oscillation.
Technical Context
The LM6134AIMX employs a dual-input-stage architecture (NPN and PNP) enabling rail-to-rail common-mode input voltage range beyond the supply rails (−0.25 V to V+ + 0.25 V), eliminating input clipping concerns in single-supply systems. Its slew-boosted output stage ensures stable 12 V/μs transient response even under capacitive loading.
It maintains ≥7 MHz GBW down to 2.7 V supply and sustains >100 dB CMRR and PSRR over 0–4 V input range at 5 V, supporting precision signal conditioning in noisy environments. The device drives ≥100 kΩ loads with ≤50 mV headroom to either rail at 25°C and remains stable driving typical TFT gamma reference bus capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10 MHz at 20 kHz - enables stable unity-gain buffers and 2nd-order filters up to ~1.6 MHz in portable systems. |
| Slew rate | 12 V/μs - supports fast settling of 20 VPP signals within <4 μs, critical for VGA/SVGA display gamma correction. |
| Supply current per amp | 360 μA at 5 V - extends battery life in dual-cell (3 V) or Li-ion (3.7 V avg) instrumentation without sacrificing bandwidth. |
| Common-mode input range | −0.25 V to V+ + 0.25 V - accepts inputs below ground or above V+, simplifying sensor interfacing in single-supply designs. |
| Rail-to-rail output swing | ≤35 mV from rails (100 kΩ load, 5 V) - maximizes dynamic range and ADC utilization in low-voltage data acquisition. |
| CMRR / PSRR | 100 dB / 82 dB - rejects power-supply ripple and common-mode noise in precision analog front-ends. |
| Operating supply range | 2.7 V to 24 V - allows single-part reuse across 3 V sensors, 5 V logic, and 12–24 V industrial I/O modules. |
Pinout & Package
LM6134AIMX is packaged in a 14-pin SOIC (D package), body size 8.65 mm × 3.91 mm, with standard JEDEC MS-012AC footprint and 1.27 mm pitch. Thermal resistance RθJA = 82.48 °C/W enables operation at full spec up to +85°C ambient without forced airflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A–D | Amplifier outputs; each drives ≥100 kΩ with rail-to-rail swing and remains stable into ≥1 nF capacitive loads. |
| 2, 5, 9, 12 | +IN A–D | Noninverting inputs; high-impedance (>100 MΩ) nodes compatible with high-Z sensors and resistor-divider networks. |
| 3, 6, 10, 13 | −IN A–D | Inverting inputs; matched to +IN pins for precision differential gain configurations and instrumentation amps. |
| 4 | V− | Negative supply terminal; accepts ground or negative rail; supports true single-supply (0 V to V+) or split-rail operation. |
| 11 | V+ | Positive supply terminal; operates up to 24 V; internal ESD protection clamps ±0.5 V beyond rails. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input beyond supply rails | Accepts −0.25 V to V+ + 0.25 V - eliminates level-shifting circuitry for ground-referenced or overvoltage sensor signals. |
| Slew-boosted output architecture | Delivers 12 V/μs while maintaining phase margin >33° into 10 kΩ || 100 pF - enables robust gamma buffer response in TFT column drivers. |
| Low-voltage operation from 2.7 V | Guarantees 10 MHz GBW and rail-to-rail output at 2.7 V - supports next-gen 3 V display panels and energy-harvesting systems. |
| High capacitive load drive | Stable with ≥1 nF load without external compensation - removes need for isolation resistors in LCD reference voltage distribution. |
| Wide supply range (2.7–24 V) | Single BOM item replaces multiple op-amps across battery, logic, and industrial rails - reduces inventory and design validation effort. |

Use Value: Input offset drift ≤5 µV/°C ensures stable baseline over body temperature variation; rail-to-rail output fully utilizes 16-bit ADC input range. |
| Flat-Panel Display Driver | Wireless Communications Baseband |
Use Scenario: Gamma correction voltage buffering for 1080p TFT-LCD source driver ICs requiring 4 μs settling to 0.1% on 12 reference voltages. IC Role / Device Role / Timing Role: One LM6134AIMX buffers four gamma reference DAC outputs; output drives 500 pF + 10 kΩ column line impedance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Lower GBW (6.4 MHz), higher IQ (550 μA/amp), same SOIC-14 package | Not suitable for >1 MHz filter or fast-settling display buffers | Select when lower bandwidth suffices and cost is primary; verify PSRR (70 dB) meets noise immunity requirements. |
| OPA4340UA | Higher precision (50 μV VOS max), lower GBW (5.5 MHz), 1.8–5.5 V supply only | Unsuitable for 12–24 V industrial or high-voltage display bias rails | Prefer for ultra-low-offset sensor conditioning at ≤5 V; avoid where wide supply or high speed is required. |
Compared with TLV2464IDR and OPA4340UA, LM6134AIMX uniquely balances 10 MHz bandwidth, 360 μA/amp efficiency, and 2.7–24 V operation - making it the only option among the three capable of serving both battery-powered instrumentation and high-voltage display subsystems with identical layout and BOM.

FAQ
What is the maximum supply voltage rating for LM6134AIMX?
The absolute maximum supply voltage (V+ − V−) for LM6134AIMX is 33 V, but the recommended operating range is 2.7 V to 24 V. Operation above 24 V is not characterized and may degrade long-term reliability or parametric performance. All electrical specifications in the datasheet are guaranteed only within the 2.7–24 V range, including 10 MHz GBW and rail-to-rail output swing.
Does LM6134AIMX support true rail-to-rail input beyond the supply rails?
Yes, LM6134AIMX supports common-mode input voltage from (V−) − 0.25 V to (V+) + 0.25 V - verified at 5 V supply. This allows direct connection of ground-referenced sensors or overvoltage transients without external level-shifting circuitry. Input protection diodes clamp currents to ≤10 mA if voltage exceeds rails by >0.5 V, preserving integrity under fault conditions.
Can LM6134AIMX drive large capacitive loads without oscillation?
Yes, LM6134AIMX is explicitly characterized for stability with ≥1 nF capacitive loads and remains unconditionally stable into 10 kΩ || 1 nF - a typical TFT gamma reference bus impedance. Its slew-boosted architecture and internal compensation eliminate need for external series resistors or feedback capacitors, simplifying layout and improving settling time in display driver applications.
What is the typical input offset voltage drift of LM6134AIMX over temperature?
The typical input offset voltage drift (dVOS/dT) of LM6134AIMX is 5 µV/°C over the full −40°C to +85°C operating range. This low drift ensures minimal baseline shift in precision DC-coupled applications such as medical sensor interfaces or strain gauge bridges, where thermal gradients can otherwise introduce significant measurement error.
Is LM6134AIMX pin-compatible with other LM613x variants like LM6134BIN?
Yes, LM6134AIMX is pin-compatible with all LM6134 variants (e.g., LM6134BIN, LM6134BIMX) in the same SOIC-14 package. Differences lie only in grade-specific parameters: LM6134AIMX guarantees ≤2 mV input offset voltage (max) and ≤5 µV/°C drift, whereas LM6134BIN specifies ≤6 mV VOS and same drift. Electrical pin functions, thermal characteristics, and layout requirements are identical across all LM6134 SOIC-14 versions.
