Product details
Overview
LM6132BIN 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 CMVR (−0.25V to 5.25V) and output swing - enabling full dynamic range in battery-powered instrumentation and flat-panel display drivers.
For engineers reviewing the LM6132BIN datasheet, LM6132BIN pinout, LM6132BIN application, or LM6132BIN equivalent, this page provides verified technical context, real-world design meaning of key specs, validated SOIC-8 pin functions, application-specific implementation insights, and two confirmed alternative op-amps with documented functional and selection trade-offs.
Technical Context
The LM6132BIN uses a complementary NPN/PNP input stage enabling true rail-to-rail common-mode input voltage operation beyond the supply rails (−0.25V to +5.25V at 5V), eliminating input clipping in single-supply systems. Its slew-boosted architecture achieves 12V/μs slew rate while maintaining stability into 100pF capacitive loads - critical for TFT LCD gamma reference buffering.
It operates across 2.7V–24V supplies, supports −40°C to +85°C ambient, and features 100dB CMRR and 82dB PSRR at 5V - ensuring robust performance in noisy industrial and portable environments where supply rejection and common-mode immunity directly impact signal fidelity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10MHz at 20kHz - enables stable unity-gain buffer or G=10 amplification up to ~1MHz without phase margin collapse. |
| Slew rate | 12V/μs - supports clean 10VPP signals up to ~190kHz before slew-induced distortion dominates. |
| Supply current per amp | 360μA at 5V - allows dual-channel operation on coin-cell or Li-ion battery for >1 year in always-on sensor front-ends. |
| Input CMVR | −0.25V to +5.25V at 5V supply - accepts inputs 0.25V below ground or 0.25V above V+, simplifying level-shifting in single-supply data acquisition. |
| Output swing (RL = 10kΩ) | Within 48mV of V+ and 32mV of V− at 5V - preserves >98% of available voltage headroom for maximum ADC input utilization. |
| CMRR | 100dB (typ) - rejects 100,000:1 common-mode interference, essential for accurate differential sensing in ECG or strain gauge amps. |
| PSRR | 82dB (typ) - attenuates power-supply ripple by 12,600×, reducing need for ultra-low-noise LDOs in mixed-signal PCBs. |
Pinout & Package
LM6132BIN is packaged in an 8-pin SOIC (D package), 4.90mm × 3.91mm body size, with standard JEDEC lead pitch and thermal pad compatibility for reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT A | Channel A output | Drives loads ≥10kΩ with rail-to-rail swing; stable into ≥100pF capacitance without external compensation. |
| 2: −IN A | Channel A inverting input | Accepts signals from −0.25V to +5.25V at 5V supply; input bias current ≤140nA enables high-Z sensor interfacing. |
| 3: +IN A | Channel A noninverting input | Matches −IN A in offset and bias; used for unity-gain buffers or high-impedance voltage followers. |
| 4: V− | Negative supply rail | Connects to ground or negative supply; supports operation down to 2.7V total supply (V+ − V−). |
| 5: +IN B | Channel B noninverting input | Independent of Channel A; enables dual-path signal conditioning (e.g., differential pair + reference buffer). |
| 6: −IN B | Channel B inverting input | Same CMVR and bias specs as −IN A; allows matched dual instrumentation amplifier topologies. |
| 7: OUT B | Channel B output | Electrically isolated from OUT A; supports independent load driving (e.g., dual DAC outputs or stereo audio paths). |
| 8: V+ | Positive supply rail | Accepts 2.7V–24V; internal regulation ensures consistent GBW and slew rate across full voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input CMVR | Operates with inputs 0.25V beyond either rail - eliminates external level-shifters in 0–5V microcontroller analog interfaces. |
| Rail-to-rail output swing | Delivers >98% of supply voltage range into 10kΩ - maximizes SNR when driving 12-bit+ SAR ADCs directly. |
| 10MHz GBW at 360μA | Enables 1MHz closed-loop bandwidth in G=10 configuration while consuming <1mW - ideal for portable spectrum analyzers. |
| Stable into 100pF loads | No external isolation resistor needed for LCD column driver buffering - reduces BOM count and layout area. |
| 2.7V–24V supply range | Single part serves both 3.3V IoT edge nodes and 24V industrial PLC analog I/O modules - cuts inventory SKUs. |
Applications

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 |
|---|---|---|---|
| TLC2272CD | Lower GBW (2.2MHz), higher IQ (1.1mA), same SOIC-8 package; 100dB CMRR but only 70dB PSRR. | Better for ultra-low-noise audio preamps (12nV/√Hz), worse for high-frequency sensor conditioning due to limited bandwidth. | Select TLC2272CD only if noise <15nV/√Hz is mandatory and bandwidth ≤200kHz suffices; avoid for >500kHz closed-loop designs. |
| OPA2340UA | Higher GBW (5.5MHz), lower IQ (200μA), same rail-to-rail I/O; requires 2.7V min but max supply capped at 5.5V. | Optimized for 3.3V/5V portable systems only; unsuitable for 12V/24V industrial analog I/O where LM6132BIN supports wider supply range. | Choose OPA2340UA for cost-sensitive 3.3V medical wearables needing lowest IQ; retain LM6132BIN for multi-voltage platform designs. |
Compared with TLC2272CD and OPA2340UA, LM6132BIN uniquely balances 10MHz bandwidth, 360μA IQ, and 2.7–24V operation - making it the only dual RRIO op-amp in its class capable of serving both battery-powered portables and wide-supply industrial signal chains without redesign.

FAQ
What is the minimum supply voltage for reliable operation of LM6132BIN?
The LM6132BIN requires a minimum supply voltage of 2.7V (V+ − V−) for guaranteed specifications across temperature. Operation below 2.7V is not characterized and may result in reduced gain-bandwidth, increased offset voltage, or instability. The device is not rated for 1.8V operation - that specification applied only to legacy die versions discontinued after revision E of the datasheet.
Does LM6132BIN support rail-to-rail input beyond the supply rails?
Yes. At 5V supply (V+ = 5V, V− = 0V), LM6132BIN accepts input voltages from −0.25V to +5.25V - extending 0.25V below ground and 0.25V above V+. This overvoltage-tolerant input stage eliminates external clamping diodes in systems with transient-coupled sensor signals or mismatched supply domains.
Can LM6132BIN drive capacitive loads without oscillation?
Yes. LM6132BIN is internally compensated to remain stable into ≥100pF capacitive loads with no external series resistor required. This capability is validated in TI's datasheet Figure 5-17 through 5-19 and enables direct connection to LCD column drivers, DAC output filters, and long PCB traces - reducing component count and layout complexity.
What is the typical input offset voltage drift of LM6132BIN over temperature?
The LM6132BIN exhibits a typical input offset voltage drift of 5µV/°C across the full −40°C to +85°C operating range. This value is specified in Section 5.6 of the datasheet under "dVOS/dT" and applies to both LM6132AI and LM6132BI variants. It ensures predictable DC error accumulation in precision integrators or long-duration sensor measurements.
Is LM6132BIN pin-compatible with other dual op-amps in SOIC-8 packages?
No. LM6132BIN has a non-standard pinout: V− is on Pin 4 and V+ on Pin 8, unlike industry-standard dual op-amps (e.g., LM358, TL072) which place V− on Pin 4 and V+ on Pin 8 but assign different functions to Pins 1, 7, and 8. Substituting LM6132BIN into existing LM358 layouts will cause incorrect biasing and functional failure - board redesign is required.
