Product details
Overview
LMC6062IM/NOPB from Texas Instruments is a dual-channel precision CMOS micropower operational amplifier optimized for battery-powered instrumentation and low-leakage signal conditioning. It delivers 100 μV typical input offset voltage, 16 μA per amplifier quiescent current, rail-to-rail output swing within 10 mV of supply rails (at 100 kΩ), ultra-low 10 fA input bias current, and 140 dB open-loop voltage gain - enabling high-accuracy DC-coupled amplification in portable medical sensors and photodiode preamplifiers.
For engineers reviewing the LMC6062IM/NOPB datasheet, LMC6062IM/NOPB pinout, LMC6062IM/NOPB application, or LMC6062IM/NOPB equivalent, this page provides verified package mapping (SOIC-8), channel-specific pin functions, confirmed electrical specifications across temperature, real-world layout guidance for high-impedance nodes, and two validated alternative op amps with documented functional trade-offs.
Technical Context
The LMC6062IM/NOPB employs TI's double-poly silicon-gate CMOS process to achieve ultra-low input bias current while maintaining stable rail-to-rail output drive into 100 kΩ loads. Its input common-mode range extends to V−, supporting true single-supply operation down to 4.5 V.
Internal compensation ensures stability across wide capacitive load conditions when used with pull-up resistors or feedback capacitance, and its latchup-immune design withstands 100 mA I/O surge currents - critical for interfacing with transducers and piezoelectric elements in field-deployed equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input offset voltage | ±100 μV typical - enables sub-millivolt DC accuracy without trimming in sensor front-ends. |
| Quiescent current per amplifier | 16 μA at 25°C - supports >1-year battery life in continuous-monitoring portable instruments. |
| Input bias current | 10 fA typical - preserves signal integrity from high-impedance sources like photodiodes and pH electrodes. |
| Rail-to-rail output swing | Within 10 mV of V+ and V− at 100 kΩ - maximizes dynamic range in 3.3 V or 5 V single-supply systems. |
| Open-loop voltage gain | 140 dB typical - ensures <0.01% gain error in precision instrumentation amplifier configurations. |
| Gain bandwidth product | 100 kHz - sufficient for low-frequency transducer signals (e.g., strain gauges, thermopiles) up to ~10 kHz. |
| Common-mode rejection ratio | 75–85 dB - maintains accuracy in noisy industrial environments with ground-referenced bridge sensors. |
Pinout & Package
LMC6062IM/NOPB is housed in an 8-pin SOIC (D package) with exposed pad not present; thermal resistance RθJA = 193.0 °C/W. Pin numbering follows standard SOIC top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Output of amplifier channel A - drives external load or next-stage input with rail-to-rail swing. |
| 2 | –IN A | Inverting input of channel A - connects to feedback network in inverting configurations. |
| 3 | +IN A | Noninverting input of channel A - interfaces directly with high-Z sources (e.g., sensor outputs). |
| 4 | V− | Negative supply terminal - referenced to ground in single-supply operation; must be decoupled. |
| 5 | +IN B | Noninverting input of channel B - electrically isolated from channel A; supports dual-sensor conditioning. |
| 6 | –IN B | Inverting input of channel B - independent signal path; no crosstalk above 155 dB at 100 Hz. |
| 7 | OUT B | Output of amplifier channel B - fully buffered; capable of sourcing/sinking ≥16 mA short-circuit current. |
| 8 | V+ | Positive supply terminal - accepts 4.5 V to 15 V single supply or ±2.25 V to ±18 V dual supply. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output stage | Delivers full supply-voltage swing into 100 kΩ loads - eliminates need for level-shifting in low-voltage data acquisition. |
| Input common-mode range includes V− | Accepts signals down to ground in single-supply mode - simplifies interface with 0–VREF transducer outputs. |
| Ultra-low input bias current (10 fA) | Minimizes voltage error across high-value feedback resistors (>1 GΩ) used in charge amplifiers and integrators. |
| Improved latchup immunity | Withstands 100 mA transient current on I/O pins - enhances reliability in ESD-prone portable medical devices. |
| High open-loop gain (140 dB) | Enables precise closed-loop gain control with standard 0.1% resistors - reduces calibration burden in production test. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision micropower operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMC6042IM/NOPB | Lower quiescent current (12 μA), reduced GBW (20 kHz), same SOIC-8 package. | Better suited for ultra-low-power (<10 μA/channel) applications where bandwidth <5 kHz is acceptable. | Select when extending battery life is prioritized over response time in static sensor measurements. |
| OPA333AIDR | Zero-drift architecture, 0.1 μV/°C offset drift, higher IQ (17 μA), same SOIC-8 footprint. | Preferred for DC-critical applications requiring <1 μV total offset drift over –40°C to +125°C. | Choose when long-term calibration stability outweighs cost sensitivity in industrial sensor modules. |
Compared with LMC6062IM/NOPB, LMC6042IM/NOPB trades bandwidth for lower power, while OPA333AIDR replaces micropower CMOS topology with zero-drift auto-zeroing to eliminate 1/f noise and drift - making it superior for precision DC measurements but less optimal for high-impedance AC-coupled photodiode circuits due to increased input current noise.

FAQ
What is the maximum supply voltage for LMC6062IM/NOPB?
The absolute maximum supply voltage (VS = V+ − V−) for LMC6062IM/NOPB is 16 V. Recommended operating range is 4.5 V to 15 V for single-supply use or ±2.25 V to ±18 V for dual-supply configurations. Exceeding 16 V risks permanent damage per the Absolute Maximum Ratings table in the SNOS631E datasheet. LMC6062IM/NOPB must never be operated above this limit, even momentarily.
Does LMC6062IM/NOPB support true rail-to-rail input?
No, LMC6062IM/NOPB does not support rail-to-rail input - its input common-mode voltage range extends to V− (including ground) but only up to (V+ − 1.9 V) at 25°C. However, it does provide rail-to-rail output swing within 10 mV of both supply rails under 100 kΩ load. This makes LMC6062IM/NOPB ideal for single-supply systems where the signal references ground but requires full output utilization.
Can LMC6062IM/NOPB drive capacitive loads directly?
LMC6062IM/NOPB is not optimized for direct capacitive load driving; stability degrades with >100 pF loads. The datasheet recommends using a series isolation resistor (e.g., 20 Ω to 100 Ω) between the output and capacitive load, or adding a pull-up resistor to V+ conducting ≥10 μA. These techniques preserve phase margin and prevent oscillation. LMC6062IM/NOPB's internal compensation is tuned for resistive loads up to 100 kΩ.
What is the input impedance of LMC6062IM/NOPB?
The differential input resistance of LMC6062IM/NOPB exceeds 10 TΩ, and its input bias current is specified at ±10 fA typical - confirming effective input impedance in the teraohm range. This value is derived from CMOS gate-isolated inputs and is validated across temperature. For practical PCB layouts, surface leakage and guard ring implementation dominate actual system-level impedance - not the device itself. LMC6062IM/NOPB's specification enables accurate modeling of >1 GΩ feedback networks.
Is LMC6062IM/NOPB suitable for photodiode transimpedance applications?
Yes, LMC6062IM/NOPB is explicitly recommended for photodiode and infrared detector preamplifiers per its official Applications list. Its 10 fA input bias current minimizes dark-current error, and its rail-to-rail output accommodates wide photocurrent ranges. Layout best practices - including guard rings, low-leakage PCB materials, and shielding - are essential to realize this performance. LMC6062IM/NOPB has been validated in production photodiode circuits with 1 GΩ feedback resistors and sub-picoamp sensitivity.
