Product details
Overview
LM6132BIM from Texas Instruments is a dual, 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-operated instrumentation and flat-panel display drivers.
For engineers reviewing the LM6132BIM datasheet, LM6132BIM pinout, LM6132BIM application, or LM6132BIM equivalent, key selection criteria include its rail-to-rail I/O capability across 2.7V–24V supply, −0.25V to 5.25V common-mode input range at 5V, and stable operation into large capacitive loads - critical for portable scanner front-ends and TFT gamma reference buffering.
Technical Context
The LM6132BIM employs a dual-input-stage architecture (NPN + PNP) enabling true rail-to-rail input voltage range beyond the supply rails (−0.25V to +5.25V at 5V), eliminating common-mode headroom constraints. Its slew-boosted output stage supports 12V/μs transient response while maintaining stability with ≥100pF capacitive loads without external compensation.
It operates across a 2.7V–24V single-supply or ±1.35V–±12V dual-supply range, with guaranteed performance over −40°C to +85°C ambient. Input offset voltage is 6mV typical (8mV max over temperature), and open-loop gain reaches 100dB into 10kΩ load - supporting precision closed-loop configurations in instrumentation amplifiers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10MHz at 20kHz - enables stable unity-gain and moderate-gain (e.g., G=10) configurations up to ~1MHz without phase margin degradation. |
| Slew rate | 12V/μs - supports full-scale 4V output transitions in ≤333ns, suitable for video-rate gamma correction buffering. |
| Supply current per amp | 360μA - allows dual-channel operation at <720μA total, extending battery life in portable scanners and handheld instruments. |
| Input CMVR (5V) | −0.25V to 5.25V - accepts signals beyond rails, simplifying level-shifting in single-supply sensor interfaces. |
| Output swing (100kΩ) | Within 30mV of rails - preserves >99% dynamic range at low 3V–5V supplies, critical for LCD reference voltage fidelity. |
| CMRR | 100dB - rejects power-supply noise and ground bounce in noisy embedded systems like wireless comms basebands. |
| PSRR | 82dB - maintains DC accuracy despite supply ripple, essential for precision analog front-ends in battery-powered instrumentation. |
Pinout & Package
LM6132BIM is packaged in an 8-pin SOIC (D package), 4.90mm × 3.91mm body size, with standard dual-op-amp pinout compatible with industry layout practices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT A (Pin 1) | Channel A output | Delivers rail-to-rail buffered signal; capable of sourcing/sinking ≥2mA into 10kΩ loads. |
| −IN A (Pin 2) | Channel A inverting input | High-impedance node (104MΩ) accepting signals down to −0.25V below V−. |
| +IN A (Pin 3) | Channel A noninverting input | Same rail-to-rail CMVR as inverting input; used for unity-gain buffers or noninverting stages. |
| V− (Pin 4) | Negative supply | Reference for both inputs and output; supports ground-referenced or split-supply operation. |
| +IN B (Pin 5) | Channel B noninverting input | Independent high-Z input identical in specs to +IN A; enables dual-channel signal processing. |
| −IN B (Pin 6) | Channel B inverting input | Matches −IN A performance; supports differential pair or independent feedback networks. |
| OUT B (Pin 7) | Channel B output | Electrically isolated from OUT A; drives separate loads without crosstalk. |
| V+ (Pin 8) | Positive supply | Accepts up to 24V; internal regulation ensures consistent biasing across full supply range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with beyond-rail tolerance | Accepts −0.25V to (V+)+0.25V signals - eliminates external level shifters in single-supply sensor interfaces. |
| Slew-boosted output stage | 12V/μs rate with inherent stability into ≥100pF - removes need for isolation resistors in LCD column driver buffering. |
| Wide 2.7V–24V supply range | Single BOM item serves 3V portable, 5V industrial, and 24V test equipment - reduces inventory complexity. |
| Low 360μA/amp quiescent current | Enables always-on signal monitoring in battery devices with multi-year runtime (e.g., handheld DMMs). |
| 100dB CMRR & 82dB PSRR | Maintains µV-level DC accuracy in electrically noisy environments like motor-driven wireless transceivers. |

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 |
|---|---|---|---|
| LMV358IDR | Lower GBW (1MHz), higher IQ (120μA/amp), same SOIC-8 package. | Not suitable for >100kHz signal paths; better for ultra-low-power sensor biasing than active filtering. | Select when bandwidth <1MHz suffices and sub-250μA total current is mandatory. |
| TLV2462CDR | Higher GBW (6.4MHz), higher IQ (550μA/amp), rail-to-rail I/O, same SOIC-8. | Superior AC performance but consumes 53% more current; less optimal for long-life battery use. | Select when 6MHz bandwidth meets requirement and extra current budget allows faster settling. |
Compared with LMV358IDR and TLV2462CDR, LM6132BIM uniquely balances 10MHz bandwidth and 360μA/amp consumption - making it the only dual RRIO op amp in SOIC-8 that supports both video-rate gamma buffering and multi-year battery life in portable instrumentation.

FAQ
What is the maximum supply voltage rating for LM6132BIM?
The absolute maximum supply voltage (V+ to V−) for LM6132BIM is 33V, but the recommended operating range is 2.7V to 24V. Operation above 24V is not characterized and may impact long-term reliability or parametric guarantees. The device is fully specified and tested at 24V, where it delivers 11MHz GBW and 390μA/amp quiescent current.
Does LM6132BIM support rail-to-rail input beyond the supply rails?
Yes, LM6132BIM supports common-mode input voltages from (V−) − 0.25V to (V+) + 0.25V - confirmed at 5V supply (−0.25V to 5.25V). This beyond-rail capability eliminates external level-shifting circuitry in single-supply sensor interfaces and allows direct connection to transducers with negative offset voltages.
Can LM6132BIM drive large capacitive loads without oscillation?
Yes, LM6132BIM is explicitly characterized for stable operation into ≥100pF capacitive loads without external compensation. Its slew-boosted output stage and internal compensation ensure ≥33° phase margin into 10kΩ || 100pF, making it suitable for TFT LCD gamma reference buffering and other high-capacitance analog routing.
What is the input offset voltage specification for LM6132BIM over temperature?
LM6132BIM has a maximum input offset voltage of 8mV over the full −40°C to +85°C operating range, with 6mV typical at 25°C. Its offset drift is 5µV/°C typical, ensuring predictable DC error accumulation in precision measurement circuits across industrial temperature extremes.
Is LM6132BIM pin-compatible with other dual op amps in SOIC-8?
LM6132BIM uses the industry-standard dual-op-amp SOIC-8 pinout (OUT A, −IN A, +IN A, V−, +IN B, −IN B, OUT B, V+), matching LM358, TLV2372, and LMV358. However, electrical differences - especially rail-to-rail I/O and 10MHz GBW - require verification of loop stability and signal swing margins in replacement designs.
