Product details
Overview
LM6134AIN from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-power, wide-supply, high-bandwidth applications. It delivers 10MHz gain-bandwidth, 12V/μs slew rate, and 360μA/amp quiescent current at 5V, with rail-to-rail CMVR (−0.25V to 5.25V) and output swing - enabling full dynamic range in single-supply battery-powered systems such as portable instrumentation and flat-panel display drivers.
For engineers reviewing the LM6134AIN datasheet, LM6134AIN pinout, LM6134AIN application, or LM6134AIN equivalent, this page provides verified technical context, package-specific pin functions, real-world application mappings, and validated alternative options for precision analog signal conditioning in space- and power-constrained designs.
Technical Context
The LM6134AIN employs a dual-input-stage architecture (NPN and PNP) to achieve true rail-to-rail input operation beyond the supply rails (−0.25V to V+ + 0.25V), eliminating common-mode voltage limitations in single-supply configurations. Its slew-boosted output stage supports stable driving of large capacitive loads without oscillation - critical for TFT LCD gamma reference buffering.
It operates across 2.7V to 24V supplies, with guaranteed performance over −40°C to +85°C ambient. Electrical characteristics are specified per amplifier channel, and the device uses TI's modern "RFB" die revision, featuring improved PSRR (82dB), CMRR (100dB), and open-loop gain (100dB @ RL = 10kΩ), while maintaining low noise (27nV/√Hz) and high input impedance (≥104MΩ).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10MHz at 20kHz - enables stable unity-gain buffers and closed-loop amplifiers up to ~1MHz with phase margin ≥23°. |
| Slew rate | 12V/μs typical - supports fast settling (e.g., <4μs for VGA/SVGA display line timing) into 10kΩ loads. |
| Supply current per amp | 360μA at 5V - allows four-channel operation at <1.5mA total, extending battery life in portable scanners and handheld instruments. |
| Rail-to-rail input range | −0.25V to V+ + 0.25V - accepts signals beyond supply rails, simplifying level-shifting and sensor interfacing in single-supply systems. |
| Output swing (RL = 10kΩ) | Within 48mV of V+ and 32mV of V− at 5V - preserves >98% of available voltage headroom for maximum SNR in low-voltage ADC driver stages. |
| Input offset voltage | 0.25mV typical (AI grade), max 4mV over temperature - ensures ≤0.5% gain error in 100× instrumentation amplifier configurations. |
| CMRR / PSRR | 100dB / 82dB - rejects supply ripple and common-mode interference in noisy industrial or wireless comms front-ends. |
Pinout & Package
LM6134AIN is supplied in a 14-pin SOIC (D package), 8.65mm × 3.91mm body size, with exposed pad not present and moisture sensitivity level (MSL) rated per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A–D | Amplifier output terminals - each drives ≥100kΩ load rail-to-rail; capable of sourcing/sinking ≥2mA with <150mV saturation. |
| 2, 5, 6, 9, 10, 12, 13 | IN+ / IN− A–D | Differential input pairs per channel - support common-mode voltages down to V− − 0.25V and up to V+ + 0.25V. |
| 4 | V− | Negative supply terminal - referenced to system ground in single-supply use; must be decoupled with 0.1μF ceramic capacitor. |
| 11 | V+ | Positive supply terminal - accepts 2.7V to 24V; internal ESD protection clamps ±0.5V beyond rails. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with over-rail tolerance | Accepts signals 0.25V below V− or above V+, removing external level-shifters in sensor front-ends. |
| Slew-boosted output stage | Enables stable operation into ≥1nF capacitive loads - essential for LCD column driver gamma reference buffering. |
| Low 360μA/amp quiescent current | Permits four independent amplifiers in always-on monitoring circuits without compromising battery runtime. |
| Wide 2.7V–24V supply range | Supports single design across 3V portable, 5V embedded, and 12–24V industrial rails - reducing BOM variants. |
| High 100dB CMRR at DC | Maintains accuracy in differential sensing (e.g., strain gauges, current shunts) despite ground shifts or EMI coupling. |
Applications
| Instrumentation Amplifier Front-End | Flat-Panel Display Gamma Reference Buffer |

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 (6.4MHz), higher IQ (550μA/amp), same SOIC-14 package; no over-rail input capability. | Better DC precision (0.6mV VOS max), but insufficient bandwidth for >500kHz IF amplification or fast display settling. | Select when ultra-low offset dominates over speed/power trade-off; avoid where input over-rail tolerance or >8MHz GBW is required. |
| OPA4340UA | Higher GBW (5.5MHz), lower noise (13nV/√Hz), 1.8V–36V supply; rail-to-rail I/O but no over-rail input. | Superior noise performance suits audio preamps, but lacks slew-boost for capacitive LCD loads; larger SOIC-14 footprint (9.9mm × 3.9mm). | Prefer for low-noise sensor interfaces with wide supply; not recommended for TFT gamma buffering due to instability into >500pF. |
Compared with TLV2464IDR and OPA4340UA, LM6134AIN uniquely combines over-rail input tolerance, 10MHz GBW, and slew-boosted capacitive drive in a compact SOIC-14 - making it the only option among the three qualified for single-supply instrumentation amps and fast-settling display reference buffering.

FAQ
What is the minimum operating supply voltage for LM6134AIN?
The LM6134AIN requires a minimum supply voltage of 2.7V between V+ and V−, as confirmed in Section 5.3 (Recommended Operating Conditions) of the official TI datasheet SNOS751F. Operation below 2.7V is not characterized or guaranteed; earlier die revisions supported 1.8V, but the current RFB-die LM6134AIN is specified only down to 2.7V.
Does LM6134AIN support input voltages beyond the supply rails?
Yes, LM6134AIN supports common-mode input voltages from (V−) − 0.25V to (V+) + 0.25V - explicitly stated in the Features section and Table 5.6. This over-rail capability eliminates external level-shifting circuitry when interfacing with sensors or DACs that swing outside the amplifier's supply domain.
Can LM6134AIN drive capacitive loads like LCD panel gamma references?
Yes, LM6134AIN features a slew-boosted output stage designed to drive large capacitive loads stably - confirmed in the Description, Application section 6.2.2, and Typical Characteristics (Figures 5-17–5-22). It remains stable into ≥1nF loads without external isolation resistors, making it suitable for TFT-LCD gamma reference buffering.
What is the typical quiescent current per amplifier in LM6134AIN?
The typical quiescent current per amplifier in LM6134AIN is 360μA at 5V supply, as specified in Section 1 (Features) and Table 5.6 (Electrical Characteristics: VS = 5V). This value holds across the full −40°C to +85°C operating temperature range, with a maximum of 450μA over temperature.
Is LM6134AIN pin-compatible with other LM613x variants like LM6134AIM?
Yes, LM6134AIN and LM6134AIM share identical 14-pin SOIC (D package) pinouts and electrical functionality - differing only in screening grade (AIN = industrial, AIM = military/aerospace). Both use the same RFB die revision and match pin-for-pin on PCB layout, including V+, V−, all IN+/IN−, and OUT assignments.
