Product details
Overview
LM6134BIMX from Texas Instruments is a quad, rail-to-rail input/output operational amplifier optimized for low-power, wide-supply applications. It delivers 10MHz gain-bandwidth, 12V/μs slew rate, and 360μA/amp quiescent current at 5V, enabling high-speed signal conditioning in battery-powered instrumentation and flat-panel display drivers.
For engineers reviewing the LM6134BIMX datasheet, LM6134BIMX pinout, LM6134BIMX application, or LM6134BIMX equivalent, key selection criteria include its −0.25V to 5.25V rail-to-rail input common-mode range, 30mV output swing from rails (RL = 100kΩ), 100dB CMRR, 82dB PSRR, and operation across 2.7V–24V supplies - critical for single-supply portable systems requiring dynamic range and stability.
Technical Context
The LM6134BIMX employs a dual-input-stage architecture (NPN + PNP) enabling true rail-to-rail input operation beyond supply rails (−0.25V to V+ + 0.25V), eliminating common-mode headroom constraints. Its slew-boosted output stage supports stable 12V/μs transient response into capacitive loads up to several nF without external compensation.
Designed for wide-voltage operation (2.7V–24V), it maintains 7–11MHz gain-bandwidth across supply extremes and sustains >100dB open-loop gain (RL = 10kΩ) with <6mV input offset voltage over −40°C to +85°C - making it suitable for precision analog front-ends in variable-supply industrial and portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10MHz at 20kHz - enables stable unity-gain buffers and 2nd-order filters up to ~1.6MHz with phase margin ≥23°. |
| Slew rate | 12V/μs - supports full-scale 10V step response in ≤0.83μs, critical for gamma correction settling in TFT LCD column drivers. |
| Supply current per amp | 360μA - allows four-channel operation at <1.44mA total, extending battery life in handheld scanners and portable medical sensors. |
| Input common-mode range | −0.25V to 5.25V (at 5V supply) - accepts signals below ground or above V+, simplifying sensor interfacing without level-shifting. |
| Output swing (RL = 100kΩ) | 30mV from each rail - delivers >99% of full-scale dynamic range at low supply voltages, maximizing ADC utilization in 3V systems. |
| CMRR / PSRR | 100dB / 82dB - rejects power-supply noise and common-mode interference in noisy embedded environments like wireless transceivers. |
| Operating supply range | 2.7V to 24V - permits direct use across battery (3.3V/5V), industrial (12V/24V), and mixed-rail subsystems without redesign. |
Pinout & Package
LM6134BIMX is packaged in a 14-pin SOIC (D package), 8.65mm × 3.91mm body size, with exposed pad not present. Pin functions are validated per TI SNOS751F Rev F (2026).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A/B/C/D | Amplifier output terminals - rail-to-rail capable, drive ≥100kΩ loads within 30mV of rails; stable into ≥1nF capacitive loads. |
| 2, 5, 6, 9, 10, 12, 13 | IN+ / IN− A–D | Differential inputs per channel - accept common-mode voltages beyond rails (−0.25V to V+ + 0.25V), enabling direct sensor connection. |
| 4, 11 | V− | Negative supply terminal - referenced to system ground in single-supply configs; supports split-rail operation down to −12V. |
| 8, 4 | V+ | Positive supply terminal - shared across all four amplifiers; decoupling required within 1cm for stability at 10MHz. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with beyond-rail tolerance | Accepts signals from −0.25V to V+ + 0.25V - eliminates need for external biasing networks in single-supply sensor interfaces. |
| Slew-boosted output stage | 12V/μs slew rate with inherent capacitive-load stability - avoids external isolation resistors in LCD gamma buffer designs. |
| Low-noise, low-drift architecture | 27nV/√Hz input voltage noise and 5µV/°C offset drift - preserves signal integrity in 16-bit data acquisition front-ends. |
| Wide-supply operation (2.7V–24V) | Single BOM item covers 3.3V IoT nodes, 5V instrumentation, and 12V/24V industrial controls - reduces inventory complexity. |
| High open-loop gain (100dB) | Ensures <0.1% gain error in unity-gain configurations with 10kΩ feedback - critical for precision reference buffering. |

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 | Less suitable for >1MHz filtering; better DC precision (0.6mV VOS max) | Select when ultra-low offset dominates over speed and power. |

FAQ
What is the maximum supply voltage rating for LM6134BIMX?
The absolute maximum supply voltage (V+ − V−) for LM6134BIMX is 33V, but the recommended operating range is 2.7V to 24V per TI SNOS751F Rev F. Operation above 24V risks exceeding thermal limits and degrading long-term reliability, even if within absolute ratings. LM6134BIMX is rated for continuous operation at 24V with junction temperature maintained ≤150°C using standard SOIC thermal design practices.
Does LM6134BIMX support rail-to-rail input beyond the supply rails?
Yes, LM6134BIMX supports rail-to-rail input with common-mode voltage range from (V−) − 0.25V to (V+) + 0.25V at 5V supply - confirmed in Section 4 and Table 5.6 of the datasheet. This allows direct connection of sensors or signals that swing slightly below ground or above V+, eliminating level-shifters in single-supply systems. LM6134BIMX achieves this via complementary NPN/PNP input stage architecture.
What is the typical output voltage swing for LM6134BIMX at 3.3V supply?
At 3.3V supply, LM6134BIMX delivers typical output swing within 30mV of each rail (i.e., 0.03V to 3.27V) with RL = 100kΩ, based on interpolation from VS = 2.7V and VS = 5V test data in Sections 5.7 and 5.6. This rail-to-rail capability ensures >98% dynamic range utilization in 3.3V systems - critical for maximizing resolution in 10–12-bit ADC interfaces driven by LM6134BIMX.
Can LM6134BIMX drive capacitive loads without oscillation?
Yes, LM6134BIMX is explicitly characterized for stable operation into large capacitive loads due to its slew-boosted output stage. The datasheet confirms stable behavior with ≥1nF loads in typical applications like LCD gamma buffers (Section 6.2.2). For loads >1nF, a small series isolation resistor (e.g., 10–50Ω) at the output is recommended to dampen potential peaking - a proven technique validated in TI's flat-panel display reference designs using LM6134BIMX.
What is the input offset voltage specification for LM6134BIMX over temperature?
LM6134BIMX ('B' grade) has a maximum input offset voltage of 8mV over the full operating temperature range of −40°C to +85°C at 5V supply, per Table 5.6. At 2.7V supply, the max VOS increases to 12mV over temperature (Section 5.7). This is consistent with its bipolar input architecture and aligns with the 6mV typical value at 25°C - making LM6134BIMX suitable for medium-precision applications where <1% gain error is acceptable in unity-gain configurations.
