Product details
Overview
LMC6062AIM/NOPB from Texas Instruments is a dual-channel precision CMOS micropower operational amplifier optimized for battery-powered instrumentation and sensor signal conditioning. It delivers 100 µV typical input offset voltage, 16 µA per amplifier quiescent current, ultra-low 10 fA input bias current, rail-to-rail output swing within 10 mV of supply rails (at 100 kΩ load), and 140 dB open-loop voltage gain - enabling high-accuracy, low-power analog front-ends in portable medical and analytical devices.
For engineers reviewing the LMC6062AIM/NOPB datasheet, LMC6062AIM/NOPB pinout, LMC6062AIM/NOPB application, or LMC6062AIM/NOPB equivalent, key selection criteria include micropower operation under 4.5–15 V single-supply conditions, femtoampere-level input bias current for photodiode and piezoelectric transducer interfacing, and guaranteed rail-to-rail output performance across –40°C to +125°C.
Technical Context
The LMC6062AIM/NOPB employs TI's double-poly silicon-gate CMOS process to achieve ultra-low input bias current and high input impedance (>10 TΩ), making it suitable for high-impedance source amplification without significant DC error. Its internal compensation ensures stability with capacitive loads when used with appropriate external resistive isolation or pull-up networks.
It supports true single-supply operation with input common-mode range extending to V− (ground) and rail-to-rail output swing - critical for maximizing dynamic range in low-voltage systems. The device features improved latchup immunity and operates reliably across –40°C to +125°C, meeting industrial and portable medical equipment requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input offset voltage | ±100 µV typical - enables sub-millivolt DC accuracy in precision transducer amplifiers without trimming. |
| Quiescent current per amplifier | 16 µA at +25°C - allows >1-year battery life in coin-cell-powered portable instruments. |
| Input bias current | 10 fA typical - preserves signal integrity when amplifying picoamp-level currents from photodiodes or pH electrodes. |
| Output swing | Within 10 mV of V+ and V− at 100 kΩ load - maximizes usable dynamic range in 3.3 V or 5 V systems. |
| Open-loop voltage gain | 140 dB (10⁷ V/V) - ensures <0.01% gain error in unity-gain buffers and low-gain instrumentation stages. |
| Gain bandwidth product | 100 kHz - supports stable DC-coupled amplification up to ~10 kHz with adequate phase margin. |
| Common-mode rejection ratio | 75 dB minimum (AI grade) - rejects power supply ripple and EMI in single-ended sensor interfaces. |
Pinout & Package
LMC6062AIM/NOPB is packaged in an 8-pin SOIC (D package) with exposed pad not present; thermal resistance RθJA = 193.0°C/W. Pin functions are validated per TI SNOS631E (Rev. March 2025).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT A | Output channel A | Amplified signal output for first op amp; rail-to-rail capable into ≥100 kΩ. |
| 2: –IN A | Inverting input channel A | High-impedance node (≥10 TΩ) for feedback network connection; sensitive to leakage. |
| 3: +IN A | Noninverting input channel A | DC-coupled input accepting common-mode voltages down to V− (ground) in single-supply mode. |
| 4: V− | Negative supply | Reference terminal for single-supply (0 V) or split-supply (e.g., –5 V) operation. |
| 5: +IN B | Noninverting input channel B | Independent second input; requires guard ring layout for femtoamp-level signal integrity. |
| 6: –IN B | Inverting input channel B | Second high-Z input; shares same ultra-low bias current spec as channel A. |
| 7: OUT B | Output channel B | Second independent rail-to-rail output; crosstalk rejection >155 dB at 100 Hz. |
| 8: V+ | Positive supply | Accepts 4.5 V to 15 V; absolute max 16 V; output short-circuit protection active. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full-scale signal headroom within 10 mV of both supply rails at 100 kΩ - eliminates need for level-shifting in low-voltage data acquisition. |
| Ultra-low input bias current | 10 fA typical enables direct coupling to high-impedance sources (e.g., glass pH electrodes, piezoelectric sensors) without measurable DC error. |
| Single-supply operation | Input common-mode range includes V− (0 V), allowing ground-referenced sensor interfaces without dual supplies or charge pumps. |
| High open-loop gain | 140 dB ensures <0.01% gain nonlinearity in unity-gain buffers and low-gain configurations - critical for precision reference buffering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision micropower op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMC6082IDR | Higher GBW (1.3 MHz vs. 100 kHz), 125 µA IQ per amplifier - trades micropower for speed. | Better suited for active filters or higher-frequency sensor interfaces (>10 kHz), not ultra-low-power portable use. | Select LMC6082IDR only if bandwidth >100 kHz is required and battery life is secondary. |
| OPA333AIDR | Zero-drift architecture; 0.1 µV/°C offset drift vs. 1 µV/°C for LMC6062AIM/NOPB; 17 µA IQ - similar power, superior DC stability. | Preferred for long-duration DC measurements (e.g., environmental logging) where drift dominates error budget. | Choose OPA333AIDR when offset drift <0.2 µV/°C is mandatory; accept slightly higher cost and different pinout. |
Compared with LMC6062AIM/NOPB, LMC6082IDR offers 13× more bandwidth at 8× higher supply current, while OPA333AIDR provides near-zero drift but lacks the same femtoampere input bias - making LMC6062AIM/NOPB uniquely balanced for high-Z, low-power, moderate-bandwidth sensor front-ends.

FAQ
What is the maximum supply voltage for LMC6062AIM/NOPB?
The absolute maximum supply voltage (VS = V+ − V−) for LMC6062AIM/NOPB is 16 V. Operation beyond this risks permanent damage. The 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 13 V on V+ while sinking output current may affect reliability per TI SNOS631E Section 5.1.
Does LMC6062AIM/NOPB support true rail-to-rail input?
No - LMC6062AIM/NOPB supports rail-to-rail *output* swing (within 10 mV of V+ and V−), but its input common-mode range extends only to V− (ground) and up to (V+) − 1.9 V at +25°C. It does not accept signals at the positive rail. This makes it ideal for ground-referenced inputs in single-supply systems but unsuitable for sensing near V+ without attenuation.
Can LMC6062AIM/NOPB drive capacitive loads directly?
Direct capacitive loading degrades phase margin and may cause oscillation. LMC6062AIM/NOPB requires external compensation - such as a series resistor (e.g., 10–100 Ω) between output and load, or a pull-up resistor to V+ conducting ≥10 µA - to stabilize operation with >100 pF loads. Figure 6-2 and 6-3 in TI SNOS631E provide validated compensation topologies.
What is the input bias current specification for LMC6062AIM/NOPB over temperature?
LMC6062AIM/NOPB specifies ±10 fA typical input bias current at +25°C, rising to ±4 pA maximum over –40°C to +85°C. This remains among the lowest published for dual op amps in SOIC packaging and is critical for preserving accuracy in high-impedance sensor interfaces like piezoelectric or ion-selective electrodes.
Is LMC6062AIM/NOPB pin-compatible with other dual op amps in SOIC-8?
No - LMC6062AIM/NOPB uses a nonstandard pinout: OUT A (pin 1), –IN A (pin 2), +IN A (pin 3), V− (pin 4), +IN B (pin 5), –IN B (pin 6), OUT B (pin 7), V+ (pin 8). It is not pin-compatible with industry-standard dual op amps (e.g., LM358, TL072, MCP6022). PCB layout must follow TI's validated SOIC-8 mapping in SNOS631E Figure 4-2.
