Product details
Overview
LM6132BIMX from Texas Instruments is a dual, rail-to-rail input/output operational amplifier optimized for low-power, high-speed portable applications. It delivers 10MHz gain-bandwidth, 12V/μs slew rate, and 360μA/amp quiescent current at 5V supply, operating across 2.7V–24V. It enables precision signal conditioning in battery-powered instrumentation and flat-panel display gamma buffers.
For engineers reviewing the LM6132BIMX datasheet, LM6132BIMX pinout, LM6132BIMX application, or LM6132BIMX equivalent, key selection criteria include rail-to-rail I/O swing at low supply voltages, capacitive load drive stability, input offset voltage drift (5µV/°C), PSRR (82dB), and SOIC-8 package compatibility with space-constrained PCB layouts.
Technical Context
The LM6132BIMX employs a complementary NPN/PNP input stage enabling true rail-to-rail common-mode input range (−0.25V to 5.25V at 5V supply) and eliminates input overvoltage concerns. Its slew-boosted output architecture supports stable 12V/μs transient response into large capacitive loads without external compensation.
It features a wide 2.7V–24V single-supply operation, 100dB open-loop gain (RL = 10kΩ), and 100dB CMRR - all maintained across −40°C to +85°C ambient temperature. The device uses TI's modern "RFB" die revision, requiring no layout changes from legacy LM6132 designs but specifying minimum 2.7V supply (not 1.8V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10MHz at 20kHz - enables stable unity-gain buffering and closed-loop amplification up to ~1MHz with phase margin ≥33°. |
| Slew rate | 12V/μs - supports fast settling of 20VPP signals in <4μs, critical for TFT LCD gamma reference buffering. |
| Supply current per amp | 360μA - extends battery life in portable scanners and handheld instruments without sacrificing bandwidth. |
| Rail-to-rail input range | −0.25V to 5.25V (at 5V supply) - accepts inputs beyond rails, simplifying sensor interface design with no level-shifting. |
| Output swing (RL = 10kΩ) | Within 48mV of positive rail and 32mV of negative rail - maximizes dynamic range in 3V systems like next-gen TFT panels. |
| CMRR | 100dB - rejects power-supply noise and common-mode interference in noisy industrial environments. |
| PSRR | 82dB - maintains DC accuracy despite supply ripple, essential for precision instrumentation amplifier front-ends. |
Pinout & Package
LM6132BIMX is housed in an 8-pin SOIC (D package), 4.90mm × 3.91mm body size, with exposed pad not present. Thermal resistance RθJA = 127.1°C/W enables operation up to +85°C ambient without forced airflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Delivers rail-to-rail buffered signal; drives up to 100pF capacitive loads stably without isolation resistor. |
| 2 (−IN A) | Channel A inverting input | High-impedance node (104MΩ); accepts signals down to −0.25V below V−, enabling ground-referenced sensor inputs. |
| 3 (+IN A) | Channel A noninverting input | Matches −IN A in bias current (140nA typ) and offset drift; used for unity-gain follower or differential pair configuration. |
| 4 (V−) | Negative supply | Reference for both channels; supports single-supply operation when tied to GND or split-rail negative source. |
| 5 (+IN B) | Channel B noninverting input | Independent input path; allows dual-channel signal processing (e.g., differential input + reference buffer) on one IC. |
| 6 (−IN B) | Channel B inverting input | Electrically identical to −IN A; enables matched dual instrumentation amp stages with minimal component count. |
| 7 (OUT B) | Channel B output | Full rail-to-rail swing; can sink/source ≥2mA - sufficient to drive LCD column driver reference inputs directly. |
| 8 (V+) | Positive supply | Accepts 2.7V–24V; internal regulation ensures consistent GBW and slew performance across full voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with extended CMVR | Operates with inputs 0.25V beyond either supply rail - eliminates need for external clamping diodes or level shifters in sensor interfaces. |
| Slew-boosted output stage | 12V/μs slew rate sustained into 100pF loads - avoids ringing in flat-panel display gamma correction circuits without series damping resistors. |
| Low-voltage operation | Functional down to 2.7V supply - supports direct integration into 3V TFT LCD subsystems without LDO pre-regulation. |
| Capacitive load drive capability | Stable with >100pF loads - enables direct connection to long PCB traces or high-C LCD column driver inputs without instability risk. |
| Wide supply range | 2.7V–24V operation - allows reuse across battery-powered (3V), industrial (12V), and high-voltage analog front-end (24V) designs, reducing BOM variants. |

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. | Targeted at cost-sensitive, low-bandwidth applications (e.g., simple comparators, basic sensors); lacks slew-boost for display drivers. | Select LMV358IDR only if bandwidth ≤1MHz suffices and ultra-low cost dominates over dynamic performance. |
| OPA2314AIDR | Higher precision (VOS = 0.75mV max), lower noise (14nV/√Hz), same 10MHz GBW and 360μA IQ. | Preferred for high-accuracy data acquisition where offset drift and noise dominate system error budget. | Choose OPA2314AIDR when VOS drift <2µV/°C and sub-15nV/√Hz noise are required - e.g., medical ECG front-ends. |
Compared with LMV358IDR, LM6132BIMX provides 10× higher bandwidth and superior capacitive drive stability; versus OPA2314AIDR, it trades minor offset/noise improvement for broader supply range (2.7–24V vs. 1.8–5.5V) and proven display driver robustness.

FAQ
What is the maximum capacitive load LM6132BIMX can drive without oscillation?
The LM6132BIMX is characterized to drive ≥100pF loads stably without external compensation, as verified in TI's application note SNOS751F Section 6.2.2. This makes it suitable for direct connection to TFT LCD column driver inputs and long PCB traces. For loads >200pF, a small series output resistor (10–50Ω) is recommended to maintain phase margin above 33°.
Does LM6132BIMX support true rail-to-rail input when powered from a 3V supply?
Yes. At VS = 3V (V+ = 3V, V− = 0V), the LM6132BIMX common-mode input voltage range is specified as 0V to 3V - fully rail-to-rail - with typical performance extending to −0.1V to 3.1V. This is confirmed in Section 5.3 Recommended Operating Conditions and Figure 5-3 of the SNOS751F datasheet.
What is the input offset voltage specification for LM6132BIMX over temperature?
The LM6132BIMX ('B' grade) has a maximum input offset voltage of 8mV over the full −40°C to +85°C operating range, with typical drift of 5µV/°C. This is documented in Table 5-6 (Electrical Characteristics at VS = 5V) and applies to both channels independently under standard test conditions.
Can LM6132BIMX be used in single-supply 2.7V applications with rail-to-rail output swing?
Yes. At VS = 2.7V, LM6132BIMX delivers rail-to-rail output swing within 40mV of V+ and 30mV of V− (RL = 100kΩ), preserving >95% of full-scale dynamic range. This is validated in Section 5.7 Electrical Characteristics: VS = 2.7V and enables accurate signal buffering in next-generation 3V TFT panels.
Is LM6132BIMX pin-compatible with earlier LM6132 variants like LM6132AIMX?
Yes. LM6132BIMX shares identical SOIC-8 pinout, electrical specifications, and thermal characteristics with LM6132AIMX and other LM6132x variants. Both use the modern "RFB" die revision and require no PCB layout changes - only verify that system-level offset voltage tolerance accommodates the 'B' grade's 6mV typical (vs. 'A' grade's 2mV typical) VOS.
