Product details
Overview
LM6132AIN from Texas Instruments is a dual, rail-to-rail input/output operational amplifier optimized for low-power, high-speed precision signal conditioning. It delivers 10MHz gain-bandwidth, 12V/μs slew rate, and 360μA per amplifier quiescent current at 5V supply, operating from 2.7V to 24V. It supports battery-operated instrumentation and flat-panel display gamma reference buffering where rail-to-rail swing and capacitive load drive are critical.
For engineers reviewing the LM6132AIN datasheet, LM6132AIN pinout, LM6132AIN application, or LM6132AIN equivalent, this page provides verified technical context, package-specific pin functions, real-world application mappings, and validated alternative options - all grounded in TI's SNOS751F production data sheet (Rev F, June 2026).
Technical Context
The LM6132AIN uses a complementary bipolar input stage enabling true rail-to-rail input common-mode range (−0.25V to 5.25V at 5V supply) and rail-to-rail output swing with <50mV headroom into 100kΩ loads. Its slew-boosted architecture ensures stable 12V/μs response without oscillation into large capacitive loads typical of TFT LCD column drivers.
It features 100dB CMRR and 82dB PSRR at 5V, supporting precision DC-coupled amplification in single-supply systems. The device maintains ≥7MHz GBW and ≥23° phase margin across 2.7V–24V supplies, enabling robust performance in portable scanners and wireless front-end signal chains.
Key Specifications

|---|---|
| Gain-bandwidth product | 10MHz at 20kHz - enables stable unity-gain buffer or 10× closed-loop amplification up to 1MHz. |
| Slew rate | 12V/μs - supports fast settling of 4V step signals in ≤0.34μs, critical for VGA/SVGA display gamma correction. |
| Supply current per amp | 360μA at 5V - allows dual-channel operation on coin-cell or Li-ion batteries for >1-year runtime in portable instrumentation. |
| Input voltage range | −0.25V to 5.25V at 5V supply - accepts inputs beyond rails, eliminating level-shifting in sensor front-ends. |
| Output swing (100kΩ) | Within 30mV of both rails - maximizes dynamic range in 3.3V or 5V systems, preserving SNR in low-voltage ADC interfaces. |
| CMRR | 100dB - rejects common-mode noise from shared ground paths in multi-sensor industrial modules. |
| PSRR | 82dB - suppresses ripple from switching regulators powering mixed-signal PCBs. |

LM6132AIN is packaged in an 8-pin SOIC (D package), 4.90mm × 3.91mm body size, rated for −40°C to +85°C operation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives capacitive loads up to 1nF without compensation; rail-to-rail swing supports full-scale DAC reference buffering. |
| 2 | −IN A | Amplifier A inverting input - high-impedance node (10⁴ MΩ) for precision feedback networks in instrumentation amps. |
| 3 | +IN A | Amplifier A noninverting input - accepts signals down to −0.25V below V−, enabling ground-referenced sensor interfacing. |
| 4 | V− | Negative supply terminal - connects to system ground or negative rail; supports dual-supply (±12V) or single-supply (0V/5V) configurations. |
| 5 | +IN B | Amplifier B noninverting input - electrically isolated from Channel A; enables independent dual-path signal conditioning. |

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 (130μA/amp), no rail-to-rail input - limited to 0.2V above V− min. | Acceptable for low-bandwidth sensor buffers but unsuitable for gamma DAC or IF filtering requiring >5MHz BW. | Select LMV358IDR only for cost-sensitive, low-speed applications where rail-to-rail input is not required. |
| TLV2462CDR | Higher IQ (550μA/amp), same 10MHz GBW, rail-to-rail I/O, but narrower supply range (2.7V–6V). | Valid for 3.3V/5V systems but cannot replace LM6132AIN in 12V/24V industrial or display backlight circuits. | Choose TLV2462CDR when operating strictly within 2.7V–6V and higher drive strength is needed over temperature. |
Compared with LMV358IDR and TLV2462CDR, the LM6132AIN uniquely balances 10MHz bandwidth, rail-to-rail input/output, ultra-low power, and 2.7V–24V flexibility - making it irreplaceable in multi-voltage portable instrumentation and wide-range display subsystems.

FAQ
What is the maximum capacitive load the LM6132AIN can drive without instability?
The LM6132AIN is characterized to drive ≥1nF capacitive loads stably without external compensation, as confirmed in TI's SNOS751F datasheet Figure 5-17 through 5-22. This capability eliminates series isolation resistors in TFT LCD gamma reference buffering, reducing board space and component count while maintaining <4μs settling for VGA/SVGA timing. The LM6132AIN achieves this via internal slew-boosted architecture and optimized output stage design.
Does the LM6132AIN support true rail-to-rail input at 2.7V supply?
Yes - at 2.7V supply, the LM6132AIN maintains rail-to-rail input common-mode range from 0V to 2.7V (per Section 5.7, VCM = 0 to 2.7V), enabling direct interface with ground-referenced sensors and 0–2.7V DAC outputs. This is distinct from "beyond-the-rails" behavior seen at higher supplies; at 2.7V, it reaches exactly to both rails with no headroom penalty, preserving full dynamic range in low-voltage systems.
What is the guaranteed output voltage swing for LM6132AIN into a 10kΩ load at 5V supply?
At 5V supply and 25°C, the LM6132AIN guarantees output swing within 48mV of the positive rail and 32mV of the negative rail into a 10kΩ load (Section 5.6, VO parameter). Over temperature (−40°C to +85°C), swing degrades to within 150mV of the positive rail and 90mV of the negative rail - still sufficient for 10-bit resolution in 5V systems where 1LSB = 4.88mV.
How does the LM6132AIN differ from the LM6132BIN in terms of input offset voltage?
The LM6132AIN has a tighter input offset voltage specification: 0.25mV (typ), 2mV (max) at 25°C, versus LM6132BIN's 0.25mV (typ), 6mV (max) at 25°C (Section 5.6). Over temperature (−40°C to +85°C), LM6132AIN max VOS is 4mV vs. 8mV for LM6132BIN. This makes LM6132AIN preferred for precision DC-coupled applications like medical sensor amplifiers where offset drift directly impacts measurement accuracy.
Is the LM6132AIN pin-compatible with other dual op amps in SOIC-8 packages?
No - the LM6132AIN pinout (OUT A, −IN A, +IN A, V−, +IN B, −IN B, OUT B, V+) is specific to the LM613x family and differs from industry-standard dual op amp pinouts (e.g., LM358, TLV2372). Substituting requires PCB layout revision. Always verify pin functions using Figure 4-1 in SNOS751F; mismatched pinouts risk supply shorting or signal inversion.
