Product details
Overview
LM6134AIM/NOPB 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, with rail-to-rail CMVR (−0.25 V to 5.25 V) and output swing - enabling full dynamic range in single-supply battery-powered instrumentation and display driver circuits.
For engineers reviewing the LM6134AIM/NOPB datasheet, LM6134AIM/NOPB pinout, LM6134AIM/NOPB application, or LM6134AIM/NOPB equivalent, this page provides verified specifications, SOIC-14 package mapping, functional pin roles, real-world use cases in TFT LCD gamma buffering and portable instrumentation amps, and two validated alternative parts with documented electrical and application-level differences.
Technical Context
The LM6134AIM/NOPB employs a dual-input-stage architecture (NPN and PNP) enabling true rail-to-rail input operation beyond the supply rails (V– −0.25 V to V+ +0.25 V), eliminating common-mode voltage constraints in single-supply systems. Its slew-boosted output stage supports stable 12 V/μs transient response into capacitive loads up to several nF without oscillation.
Designed for supply flexibility, it operates from 2.7 V to 24 V with consistent 10 MHz GBW across voltage range and maintains >100 dB CMRR and 82 dB PSRR at DC - critical for precision signal conditioning in noisy industrial or portable environments where supply rejection and common-mode immunity directly impact measurement fidelity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10 MHz at 20 kHz - enables stable unity-gain buffer or gain-of-10 amplification up to ~1 MHz without phase margin collapse. |
| Slew rate | 12 V/μs - supports fast settling of 20 VPP signals in ≤1.7 μs, suitable for gamma reference buffering in SVGA TFT displays. |
| Supply current per amp | 360 μA at 5 V - allows four-channel operation at <1.5 mA total, extending battery life in portable scanners and handheld meters. |
| Input CMVR | −0.25 V to 5.25 V (at 5 V supply) - accepts inputs 0.25 V below ground or 0.25 V above V+, simplifying sensor interfacing without level-shifting. |
| Output swing (RL = 10 kΩ) | Within 48 mV of V+ and 32 mV of V− - preserves >98% of available voltage headroom for maximum SNR in low-voltage systems. |
| CMRR | 100 dB (typical, 0–4 V CM range) - rejects 100,000:1 of common-mode interference, essential for high-precision instrumentation amplifier front-ends. |
| PSRR | 82 dB - suppresses supply ripple by 126×, reducing need for ultra-clean LDOs in mixed-signal display subsystems. |
Pinout & Package
LM6134AIM/NOPB is housed in a 14-pin SOIC (D package) with 8.65 mm × 3.91 mm body size and standard 1.27 mm pitch. Pin functions are electrically isolated per channel and support independent configuration of each op-amp section.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A/B/C/D | Amplifier output terminals - each drives its own load; rail-to-rail swing enables direct interface to ADC references or LCD column drivers. |
| 2, 6, 9, 13 | −IN A/B/C/D | Inverting inputs - matched for low offset drift; accept signals down to V− − 0.25 V, supporting ground-referenced sensor outputs. |
| 3, 5, 10, 12 | +IN A/B/C/D | Noninverting inputs - high-impedance (>100 MΩ) nodes ideal for passive filter taps or high-Z transducer connections. |
| 4 | V− | Negative supply rail - shared across all four amplifiers; must be decoupled locally to minimize crosstalk in multi-channel filtering. |
| 11 | V+ | Positive supply rail - supports 2.7–24 V operation; internal ESD protection clamps ±0.5 V beyond rails. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal handling on single 3.3 V or 5 V supplies - eliminates external level shifters in portable medical sensors and data loggers. |
| 10 MHz GBW at 360 μA/amp | Delivers bandwidth previously requiring >2 mA per amp - reduces system power by >80% in battery-operated wireless sensor nodes. |
| Stable driving of large capacitive loads | Operates without external compensation into ≥1 nF loads - simplifies gamma voltage distribution in 1080p LCD panels without series resistors. |
| Wide 2.7 V to 24 V supply range | Allows one BOM item across multiple subsystems - e.g., same LM6134AIM/NOPB used for 3.3 V analog front-end and 12 V display biasing in industrial HMIs. |
| 100 dB CMRR and 82 dB PSRR | Maintains accuracy in noisy environments - critical for strain gauge amplifiers in motor control feedback loops where supply ripple and EMI coexist. |

Use Value: 12 V/μs slew rate and capacitive-load stability ensure monotonic settling without overshoot, meeting TFT column driver timing specs. |
| Battery-Powered Scanner Signal Chain | Low-Voltage Industrial Sensor Interface |
Use Scenario: Analog signal conditioning in handheld barcode scanner with photodiode array and 12-bit SAR ADC. IC Role / Device Role / Timing Role: Transimpedance amplifier + programmable gain stage - two LM6134AIM/NOPB channels used per scan line. Use Value: 360 μA/amp current draw extends AA battery life to >10 hours; 10 MHz GBW supports >500 kSPS sampling with anti-alias filtering. |
Use Scenario: Signal conditioning for 4–20 mA loop-powered pressure transmitter operating from 9–36 V supply. IC Role / Device Role / Timing Role: I/V conversion and output buffering - one LM6134AIM/NOPB channel used per transmitter channel in multi-sensor modules.

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. | Less suitable for >500 kHz closed-loop designs; better for ultra-low-noise (<20 nV/√Hz) but lower-speed sensor interfaces. | Choose TLV2464IDR when noise performance outweighs bandwidth needs and supply current budget allows +50% increase. |
| OPA4340UA | Higher precision (50 μV VOS max), lower GBW (5.5 MHz), same rail-to-rail I/O, SOIC-14. | Optimized for DC-critical applications (e.g., weigh scales); insufficient bandwidth for fast gamma settling in HD displays. | Choose OPA4340UA only when offset voltage <50 μV is mandatory and bandwidth requirements are ≤200 kHz. |
Compared with TLV2464IDR and OPA4340UA, LM6134AIM/NOPB uniquely balances 10 MHz bandwidth, 360 μA/amp efficiency, and rail-to-rail operation - making it the only option among the three capable of driving TFT gamma references while maintaining battery life in portable scanners.

FAQ
What is the maximum capacitive load LM6134AIM/NOPB can drive without instability?
LM6134AIM/NOPB is characterized to drive ≥1 nF loads stably without external compensation, as confirmed in TI's application note SNOS751F Section 6.2.2 for TFT LCD gamma buffering. This capability eliminates series output resistors in display driver applications and ensures monotonic settling within 4 μs for SVGA resolution - a key requirement validated across temperature and supply voltage ranges from 2.7 V to 24 V.
Does LM6134AIM/NOPB support true rail-to-rail input beyond the supply rails?
Yes. LM6134AIM/NOPB accepts common-mode inputs from (V− − 0.25 V) to (V+ + 0.25 V) - explicitly verified in Section 5.6 of the datasheet. This "beyond-the-rails" input range allows direct connection of ground-referenced sensors or bipolar signal sources without level-shifting circuitry, a feature critical in single-supply portable instrumentation where V− = 0 V.
What is the typical output voltage swing for LM6134AIM/NOPB at 3.3 V supply?
At VS = 3.3 V, LM6134AIM/NOPB delivers typical output swing within 40 mV of V+ and 30 mV of V− (per extrapolation from 2.7 V and 5 V test data in Sections 5.7 and 5.6). This yields >95% usable dynamic range - essential for maximizing SNR in 12-bit ADC interfaces powered from low-dropout regulators in handheld devices.
Is LM6134AIM/NOPB pin-compatible with earlier LM6134 variants like LM6134ACN/NOPB?
No. LM6134AIM/NOPB uses the SOIC-14 (D) package, while LM6134ACN/NOPB uses PDIP-14 (NFF). Though both share identical pin functions and electrical behavior, the physical packages differ - requiring PCB layout changes. The "M" suffix denotes SOIC packaging per TI's orderable part numbering convention.
How does the slew-boosted architecture in LM6134AIM/NOPB improve performance over legacy die?
The new-die LM6134AIM/NOPB (CSO = RFB) implements a slew-boosted output stage, increasing typical slew rate to 12 V/μs versus 8 V/μs in the old GF6 die - directly improving settling time for large-signal transients. This enhancement is documented in Section 5.10 and enables reliable 20 VPP signal handling in flat-panel display gamma buffers where fast edge fidelity is required.
