Product details
Overview
LM6132AIMX from Texas Instruments is a dual, rail-to-rail input/output operational amplifier optimized for low-power, high-speed precision applications. It delivers 10MHz gain-bandwidth, 12V/μs slew rate, and 360μA/amp quiescent current at 5V supply, with rail-to-rail input CMVR (−0.25V to 5.25V) and output swing - enabling full dynamic range in battery-powered instrumentation and portable display drivers.
For engineers reviewing the LM6132AIMX datasheet, LM6132AIMX pinout, LM6132AIMX application, or LM6132AIMX equivalent, key selection considerations include its 2.7V–24V wide supply range, 100dB CMRR, 82dB PSRR, ability to drive capacitive loads without oscillation, and SOIC-8 package compatibility with space-constrained PCB layouts.
Technical Context
The LM6132AIMX employs complementary NPN/PNP input stages enabling true rail-to-rail input operation beyond the supply rails (±0.25V), eliminating common-mode voltage range limitations in single-supply systems. Its slew-boosted output architecture supports stable 12V/μs transient response while maintaining phase margin ≥23° across 2.7V–24V supplies.
Designed for unity-gain stable operation with RL ≥ 5kΩ, it achieves 7–11MHz gain-bandwidth depending on supply voltage (7MHz at 2.7V, 11MHz at 24V), and sustains rail-to-rail output swing down to 30mV from each rail into 100kΩ - critical for maximizing signal fidelity in low-voltage TFT LCD gamma reference buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10MHz at 20kHz (enables stable AC-coupled signal conditioning up to ~1MHz closed-loop bandwidth) |
| Slew rate | 12V/μs (supports fast settling of 4μs required in VGA/SVGA display column driver buffering) |
| Supply current per amp | 360μA at 5V (extends battery life in portable scanners and handheld instruments) |
| Input CMVR | −0.25V to 5.25V at 5V supply (accepts inputs beyond rails, simplifying sensor interface design) |
| Output swing (100kΩ) | Within 30mV of both rails (preserves >99% dynamic range at 3.3V or 5V supply) |
| CMRR | 100dB (rejects common-mode noise in noisy industrial or automotive sensor front-ends) |
| PSRR | 82dB (maintains DC accuracy despite supply ripple in battery+LDO systems) |
Pinout & Package
LM6132AIMX is housed in an 8-pin SOIC (D package), 4.90mm × 3.91mm body size, with standard dual-op-amp pinout compatible with industry-layout conventions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT A | Channel A output | Delivers rail-to-rail buffered signal; drives capacitive loads up to 1000pF without compensation |
| 2: −IN A | Channel A inverting input | High-impedance node (104MΩ) accepting signals from −0.25V to +5.25V at 5V supply |
| 3: +IN A | Channel A noninverting input | Same CMVR as inverting input; enables true differential sensing across full supply range |
| 4: V− | Negative supply | Accepts ground or negative rail; input protection diodes clamp to this pin |
| 5: +IN B | Channel B noninverting input | Independent high-Z input identical to Pin 3; supports dual-channel instrumentation topologies |
| 6: −IN B | Channel B inverting input | Matches Pin 2 performance; enables matched gain-setting resistor networks |
| 7: OUT B | Channel B output | Electrically isolated from OUT A; supports independent feedback paths |
| 8: V+ | Positive supply | Accepts 2.7V–24V; internal regulation ensures consistent biasing across voltage range |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input beyond supply rails | CMVR extends 0.25V below V− and 0.25V above V+, removing level-shifting circuitry in sensor interfaces |
| Slew-boosted output stage | 12V/μs rate maintained over full 2.7V–24V supply range, enabling fast settling in display gamma buffers |
| Capacitive load drive stability | Stable with ≥1000pF loads without external compensation - essential for LCD column driver interconnects |
| Wide supply voltage range | Operates from 2.7V (3.3V logic) to 24V (industrial analog backplanes), reducing BOM count across platforms |
| Low input bias current | 110nA typical (25°C) enables high-impedance transducer interfacing without significant offset error |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Lower GBW (6.4MHz), higher IQ (550μA/amp), same SOIC-8 package | Less suitable for >1MHz signal paths; better for ultra-low-noise <10kHz sensor amps | Select TLV2462IDR only when priority is input voltage noise (22nV/√Hz) over speed/power trade-off |
| OPA2314AIDR | Higher precision (VOS = 0.75mV max), lower IQ (250μA/amp), but narrower supply (1.8V–5.5V) | Not viable for 12V/24V industrial systems; ideal for 3.3V-only portable designs | Choose OPA2314AIDR when offset drift <2μV/°C and supply <5.5V constrain the system architecture |
Compared with TLV2462IDR and OPA2314AIDR, LM6132AIMX uniquely balances 10MHz bandwidth, 360μA/amp efficiency, and 2.7V–24V flexibility - making it the only option supporting both battery-powered portables and wide-supply industrial signal chains without redesign.

FAQ
What is the maximum supply voltage rating for LM6132AIMX?
The absolute maximum supply voltage (V+ to V−) for LM6132AIMX is 33V, but the recommended operating range is 2.7V to 24V. Operation above 24V is not characterized and may degrade long-term reliability or parametric performance. The LM6132AIMX datasheet specifies guaranteed operation only within the 2.7V–24V band, including all electrical characteristics and thermal limits.
Does LM6132AIMX support rail-to-rail input beyond the supply rails?
Yes, LM6132AIMX supports rail-to-rail input with common-mode voltage range extending −0.25V below V− and +0.25V above V+ at 5V supply. This feature allows direct connection of sensors or DACs whose outputs exceed the supply rails, eliminating external level-shifting components. The input stage uses complementary NPN/PNP transistors to achieve this extended range.
Can LM6132AIMX drive large capacitive loads without oscillation?
Yes, LM6132AIMX is designed to drive ≥1000pF capacitive loads stably without external compensation. Its slew-boosted output stage and internal frequency compensation maintain ≥23° phase margin even with heavy capacitive loading - a key requirement verified in TI's flat-panel display driver reference designs using LM6132AIMX to buffer gamma reference voltages.
What is the typical input offset voltage for LM6132AIMX?
The typical input offset voltage for LM6132AIMX is 2mV at 25°C and 5V supply, with a maximum of 4mV over the full −40°C to +85°C temperature range. This value applies specifically to the 'AI' grade (LM6132AI), which is the variant designated by the LM6132AIMX part number. The 'BI' grade has higher offset (6mV typ, 8mV max).
Is LM6132AIMX pin-compatible with other dual op-amps in SOIC-8?
LM6132AIMX follows the industry-standard dual op-amp pinout (SOIC-8): Pin 1 = OUT A, Pin 2 = −IN A, Pin 3 = +IN A, Pin 4 = V−, Pin 5 = +IN B, Pin 6 = −IN B, Pin 7 = OUT B, Pin 8 = V+. It is pin-compatible with TL072, TLC272, and OPA234 - but functional substitution requires verification of GBW, input stage type, and output drive capability, as LM6132AIMX uses a unique complementary input stage.
