Product details
Overview
LM6132AIM 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-powered instrumentation and portable displays.
For engineers reviewing the LM6132AIM datasheet, LM6132AIM pinout, LM6132AIM application, or LM6132AIM 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 driving capacitive loads-critical for TFT LCD gamma reference buffering and single-supply instrumentation amps.
Technical Context
The LM6132AIM integrates complementary NPN/PNP input stages 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 architecture achieves 12V/μs slew rate while maintaining stability into ≥1000pF capacitive loads without external compensation.
Designed for wide-supply flexibility, it operates from 2.7V to 24V with 100dB CMRR and 82dB PSRR at 5V, supporting precision DC-coupled amplification and AC signal paths in mixed-voltage systems-from 3V portable scanners to 24V industrial analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10MHz at 20kHz - enables stable unity-gain buffer or 10× closed-loop amplification up to 1MHz. |
| Slew rate | 12V/μs - supports clean 10VPP signals up to ~200kHz without slew-induced distortion. |
| Supply current per amp | 360μA at 5V - allows dual-channel operation on coin-cell batteries for >1-year portable instrument life. |
| Rail-to-rail input range | −0.25V to 5.25V at 5V supply - accepts inputs 0.25V below V− and 0.25V above V+, simplifying sensor interfacing. |
| Output swing (RL = 10kΩ) | Within 48mV of V+ and 32mV of V− at 5V - preserves >98% dynamic range for low-voltage ADC drivers. |
| CMRR | 100dB - rejects 100μV of common-mode error per volt of interference in noisy environments. |
| PSRR | 82dB - attenuates 12.6× power-supply ripple, critical for clean biasing in shared-rail systems. |
Pinout & Package
LM6132AIM is packaged in an 8-pin SOIC (D package) with 4.90mm × 3.91mm body size, rated for −40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT A (Pin 1) | Amplifier A output | Drives loads down to 5kΩ while maintaining rail-to-rail swing; stable into ≥1000pF. |
| −IN A (Pin 2) | Amplifier A inverting input | Accepts signals from −0.25V to +5.25V at 5V supply; high-impedance (104MΩ) node. |
| +IN A (Pin 3) | Amplifier A noninverting input | Same rail-to-rail CMVR as −IN A; matched offset and bias for precision differential gain. |
| V− (Pin 4) | Negative supply rail | Reference for both amplifiers; supports ground-referenced or split-supply operation. |
| +IN B (Pin 5) | Amplifier B noninverting input | Electrically identical to +IN A; enables independent dual-channel configuration. |
| −IN B (Pin 6) | Amplifier B inverting input | Matched performance to −IN A; supports fully differential or dual-single-ended topologies. |
| OUT B (Pin 7) | Amplifier B output | Independent output stage; no crosstalk with OUT A under typical load conditions. |
| V+ (Pin 8) | Positive supply rail | Accepts 2.7V–24V; internal regulation ensures consistent GBW and slew across full range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with over-rail tolerance | Accepts inputs 0.25V beyond V−/V+ rails-enables direct connection to sensors or DACs without level-shifting. |
| Slew-boosted output architecture | Delivers 12V/μs slew while remaining stable into 1nF loads-eliminates need for isolation resistors in LCD gamma buffers. |
| Wide supply range (2.7V–24V) | Single BOM item serves 3V portable, 5V embedded, and 24V industrial designs-reduces inventory complexity. |
| Low input bias current (110nA typ) | Minimizes voltage error across high-impedance sources like pH electrodes or photodiode transimpedance feedback networks. |
| High open-loop gain (100dB @ 10kΩ) | Ensures <0.1% gain error in unity-gain buffers and <0.01% error in 10× inverting amplifiers at DC–1kHz. |

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 (150μA/amp), same SOIC-8 package | Optimized for ultra-low-power (<100μA) microcontroller IO buffering-not suitable for >100kHz signal paths | Select LM6132AIM when bandwidth >1MHz or slew rate >1V/μs is required; LMV358IDR only for DC/low-frequency sensing. |
| TLV2462CDR | Higher IQ (550μA/amp), wider GBW (6.4MHz), same rail-to-rail I/O | Superior drive strength (30mA short-circuit) but consumes 53% more current at 5V | Choose TLV2462CDR for heavier loads (>10mA) or tighter THD+N specs; LM6132AIM preferred for battery runtime-critical designs. |
Compared with LMV358IDR and TLV2462CDR, LM6132AIM uniquely balances 10MHz bandwidth, 12V/μs slew, and 360μA/amp consumption-making it the only dual RRIO op amp in its class capable of driving 1nF loads at >100kHz while sustaining multi-year battery life.

FAQ
What is the minimum supply voltage for LM6132AIM?
The LM6132AIM requires a minimum supply voltage of 2.7V, as confirmed in Section 5.3 "Recommended Operating Conditions" of the official TI datasheet (SNOS751F, Rev F). Operation below 2.7V is not guaranteed-unlike earlier die versions that supported 1.8V, the current LM6132AIM uses the new RFB die with 2.7V absolute minimum. This ensures specified rail-to-rail input range and 10MHz GBW performance.
Does LM6132AIM support rail-to-rail input beyond the supply rails?
Yes, LM6132AIM supports rail-to-rail input with over-rail capability: its common-mode input voltage range extends to (V−) − 0.25V and (V+) + 0.25V at 5V supply, per Section 5.6 Electrical Characteristics. This allows direct interfacing with sensors or DACs whose outputs exceed the op amp's own supply rails-critical for single-supply systems where external level-shifting would add cost and error.
Can LM6132AIM drive large capacitive loads without oscillation?
Yes, LM6132AIM is specifically characterized to drive ≥1000pF capacitive loads stably without external compensation, as stated in the "Description" section and verified in Figure 5-17 through 5-22 of the TI datasheet. Its slew-boosted output architecture provides inherent phase margin preservation-making it ideal for TFT LCD gamma reference buffering where trace capacitance often exceeds 1nF.
What is the typical quiescent current of LM6132AIM at 3.3V supply?
At 3.3V supply, LM6132AIM draws 330μA per amplifier (660μA total), per Section 5.7 "Electrical Characteristics: VS = 2.7V" in the TI datasheet. This value is measured at TA = 25°C with RL > 1MΩ and VCM = V+/2. The current remains stable across temperature (−40°C to +85°C), with max 450μA/amp over full range-enabling predictable battery-life estimation in portable designs.
Is LM6132AIM pin-compatible with other LM613x variants like LM6132BIN?
Yes, LM6132AIM is pin-compatible with all LM6132 variants (e.g., LM6132BIN, LM6132BIM) in the same SOIC-8 (D) or PDIP-8 (P) packages, as confirmed by identical Pin Functions tables in Section 4 of the TI datasheet. Differences are limited to grade (A = ±2mV VOS, B = ±6mV VOS) and temperature range (I = −40°C to +85°C), not pinout or electrical interface-allowing drop-in replacement within the same package footprint.
