Product details
Overview
LMC6082AIM from Texas Instruments is a precision dual CMOS operational amplifier optimized for low-offset, ultra-low-input-bias-current applications operating from 4.5 V to 15 V single supply. It delivers 150 μV typical input offset voltage, 10 fA typical input bias current, rail-to-rail output swing within 20 mV of supply rails (at 100 kΩ load), and 130 dB open-loop voltage gain - enabling high-accuracy signal conditioning in medical instrumentation, photodiode preamplifiers, and transducer interfaces.
For engineers reviewing the LMC6082AIM datasheet, LMC6082AIM pinout, LMC6082AIM application, or LMC6082AIM equivalent, key selection considerations include its guaranteed −40°C to +85°C operating junction temperature range, SOIC-8 package with 193°C/W thermal resistance, input common-mode range extending to V−, and compatibility with single-supply precision topologies such as instrumentation amplifiers and charge amplifiers.
Technical Context
The LMC6082AIM uses TI's Double-Poly Silicon-Gate CMOS process to achieve ultra-low input bias current without compromising speed or stability. Its output stage draws directly from the internal integrator - not a conventional push-pull buffer - enabling rail-to-rail swing under heavy loads while maintaining low output impedance and high large-signal gain.
This architecture supports stable operation with capacitive loads when paired with external compensation (e.g., pull-up resistor or feedback capacitor), and includes improved latchup immunity rated for 100 mA I/O surge current. Input common-mode range includes ground, and PSRR exceeds 75 dB across both supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 150 μV typical - enables sub-mV error budgets in precision DC-coupled sensor front-ends |
| Input Bias Current | 10 fA typical - preserves signal integrity in high-impedance sources like photodiodes and piezoelectric transducers |
| Supply Voltage Range | 4.5 V to 15 V single supply - supports battery-powered and industrial 5 V/12 V systems without split supplies |
| Output Swing | Within 20 mV of rails at 100 kΩ - maximizes dynamic range in low-voltage ADC interfacing |
| Open-Loop Gain | 130 dB - ensures <0.01% gain error in unity-gain buffers and high-precision closed-loop configurations |
| Slew Rate | 1.5 V/μs typical - supports >10 kHz bandwidth in unity-gain follower applications |
| Gain-Bandwidth Product | 1.3 MHz - defines usable small-signal bandwidth for gain ≥10 configurations |
| Input Common-Mode Range | Includes V− (ground) - allows direct sensing of signals referenced to system ground in single-supply designs |
Pinout & Package
LMC6082AIM is housed in an 8-pin SOIC (Package Drawing D), 3.91 mm × 4.90 mm body, 1.75 mm max height, with standard JEDEC MS-012AA footprint and 1.27 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 5 | Non-Inverting Input (Amplifier B) | Independent high-Z input for second channel; identical specs to Pin 2 |
| 6 | Inverting Input (Amplifier B) | Independent high-Z input for second channel; identical specs to Pin 1 |
| 7 | Output (Amplifier B) | Second rail-to-rail output; amp-to-amp isolation >140 dB minimizes crosstalk |
| 8 | V+ (Positive Supply) | Single-supply rail; supports 4.5–15 V; ESD tolerance 2 kV HBM |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMC6082IMX/NOPB | Same die, same electrical specs, but rated for −40°C to +85°C industrial temp range and offered in SOIC-8 tape-and-reel (2500 pcs) | Identical functional use; differs only in packaging format and ordering part number - no design change required | Select LMC6082IMX/NOPB for volume production requiring reel delivery; LMC6082AIM is tube-packaged (95 pcs) and NRND status indicates limited new-design use |
| OPA2182 | Lower 0.02 μV/°C offset drift, 5.7 nV/√Hz voltage noise, but higher 550 μA supply current and 10 pA input bias current | Better DC precision and noise, but unsuitable for ultra-low-power or ultra-high-impedance (>100 MΩ) applications | Choose OPA2182 where ultra-low drift dominates over input bias current; retain LMC6082AIM where fA-level bias current is mandatory |
Compared with LMC6082IMX/NOPB, the LMC6082AIM shares identical performance but differs in packaging and lifecycle status; versus OPA2182, the LMC6082AIM trades higher noise and drift for 55× lower input bias current - making it irreplaceable in femtoampere-sensitivity applications.

FAQ
What is the operating temperature range for the LMC6082AIM?
The LMC6082AIM is specified for −40°C to +85°C junction temperature operation, matching the LMC6082AI grade. This range supports deployment in industrial control panels, portable diagnostic equipment, and automotive cabin-sensing modules where ambient temperatures remain within commercial limits.
Does the LMC6082AIM support true rail-to-rail input?
No - the LMC6082AIM features rail-to-rail *output* swing and an input common-mode range that *includes V−*, but its input does not extend to V+. The maximum input voltage is V+ − 1.9 V (typical), so it is not a full rail-to-rail input device. This limitation must be observed in high-side sensing applications.
Can the LMC6082AIM drive capacitive loads directly?
The LMC6082AIM can drive moderate capacitive loads (≤100 pF) stably in unity-gain configuration, but larger loads require external compensation per Figures 26–27 in the datasheet - such as a pull-up resistor to V+ or feedback capacitor Cf. Uncompensated direct driving of >500 pF may cause ringing or oscillation.
What is the difference between LMC6082AIM and LMC6082AIMX/NOPB?
The LMC6082AIM is tube-packaged (95 units), while LMC6082AIMX/NOPB is tape-and-reel packaged (2500 units), both in SOIC-8. Electrically identical, both are RoHS-compliant and rated for −40°C to +85°C. The "X" suffix denotes reel packaging; "/NOPB" confirms lead-free finish. LMC6082AIM carries NRND status, whereas LMC6082AIMX/NOPB is ACTIVE.
Is the LMC6082AIM suitable for photodiode transimpedance applications?
Yes - the LMC6082AIM is explicitly recommended for photodiode and infrared detector preamplifiers due to its 10 fA typical input bias current, which minimizes error across high-value feedback resistors (e.g., 1 GΩ). Its low input voltage noise (22 nV/√Hz) and stable phase margin further support high-gain, wide-dynamic-range optical sensing.
