Product details
Overview
LMC6062IM from Texas Instruments is a dual-channel, precision CMOS micropower operational amplifier optimized for single-supply operation at 4.5V–15V, delivering 100μV typical offset voltage, 16μA per amplifier quiescent current, and rail-to-rail output swing within 10mV of supply rails under 100kΩ load - enabling high-accuracy signal conditioning in battery-powered medical sensors and portable instrumentation.
For engineers reviewing the LMC6062IM datasheet, LMC6062IM pinout, LMC6062IM application, or LMC6062IM equivalent, key selection considerations include ultra-low input bias current (10fA), input common-mode range extending to V−, high open-loop gain (140dB), and SOIC-8 packaging with verified dual-channel isolation and crosstalk rejection >155dB.
Technical Context
The LMC6062IM employs TI's double-poly silicon-gate CMOS process to achieve true rail-to-rail output stage operation while maintaining stability across capacitive loads up to 1nF when compensated with external resistors. Its input stage includes guarded p-channel MOSFETs enabling 10fA bias current and >10TΩ input resistance.
It supports precision single-supply configurations with input common-mode voltage spanning from V− to (V+ − 1.9V) and delivers 100kHz gain-bandwidth product with 20–35V/ms slew rate - balancing micropower efficiency against usable bandwidth for sensor front-ends and low-frequency instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset voltage | ±100μV typical - enables sub-mV DC accuracy in transducer amplifiers without trimming |
| Supply current per amp | 16μA at +25°C - allows >1-year battery life in coin-cell-powered portable analyzers |
| Input bias current | 10fA typical - preserves signal integrity in photodiode and piezoelectric charge amplifiers |
| Output swing | Within 10mV of rails at 100kΩ - maximizes dynamic range in 5V single-supply systems |
| Open-loop gain | 140dB - ensures <0.01% gain error in unity-gain buffers and precision integrators |
| Crosstalk | 155dB - prevents inter-channel coupling in dual-sensor differential measurement setups |
| Gain-bandwidth | 100kHz - supports stable closed-loop operation up to ~10kHz with 10× gain |
Pinout & Package
LMC6062IM is packaged in an 8-pin SOIC (D package) with exposed pad not present; thermal resistance RθJA = 193°C/W. Pin functions are electrically isolated between channels A and B, supporting independent dual-amplifier configurations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT A | Output channel A | Delivers rail-to-rail buffered signal; requires no pull-up for most loads ≤100kΩ |
| 2: –IN A | Inverting input channel A | High-impedance node; guard ring routing essential for <100fA leakage applications |
| 3: +IN A | Noninverting input channel A | Accepts common-mode voltages down to V−; enables ground-referenced sensor interfacing |
| 4: V− | Negative supply | Reference for both channels; must be decoupled locally with 0.1μF ceramic capacitor |
| 5: +IN B | Noninverting input channel B | Independent of channel A; supports dual-sensor or differential pair topologies |
| 6: –IN B | Inverting input channel B | Electrically isolated from channel A inputs; crosstalk < −155dB at 100Hz |
| 7: OUT B | Output channel B | Full rail-to-rail swing capability identical to OUT A; no shared internal nodes |
| 8: V+ | Positive supply | Supports 4.5V–15V range; internal ESD protection rated ±2000V HBM |
Key Features

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 |
|---|---|---|---|
| LMC6042IM | Lower quiescent current (12μA), reduced GBW (20kHz), same SOIC-8 package | Better suited for ultra-low-power (<10μA system budget) but lower-bandwidth (<1kHz) sensing | Select LMC6042IM only if bandwidth demand is <5kHz and offset tolerance allows ±250μV |
| OPA2333AIDR | Zero-drift architecture, 0.1μV/°C drift, higher IQ (17μA), same SOIC-8 | Superior long-term DC stability in thermally varying environments; no 1/f noise | Choose OPA2333AIDR when drift-critical applications (e.g., lab-grade pH meters) require <0.5μV/°C max drift |
Compared with LMC6062IM, LMC6042IM trades bandwidth and offset for lower power, while OPA2333AIDR replaces micropower CMOS topology with zero-drift chopper design - offering superior DC stability at the cost of higher EMI susceptibility and 10× higher input current noise.

FAQ
What is the maximum supply voltage rating for LMC6062IM?
The absolute maximum supply voltage (VS = V+ − V−) for LMC6062IM is 16V. Recommended operating range is 4.5V to 15V for single-supply use or ±2.25V to ±18V for dual-supply configurations. Exceeding 16V risks permanent damage per TI's Absolute Maximum Ratings table in SNOS631E.
Does LMC6062IM support true rail-to-rail input operation?
No - LMC6062IM features rail-to-rail *output* swing but its input common-mode range extends only to V− and up to (V+ − 1.9V) at 25°C. It does *not* accept signals at the positive rail, distinguishing it from full rail-to-rail input/output op amps like the TLV2462.
Can LMC6062IM drive capacitive loads directly?
LMC6062IM is not unity-gain stable into pure capacitive loads. Driving >100pF requires external compensation: either a series resistor (≥100Ω) between output and load, or a parallel RC network (e.g., 90kΩ + 20pF) as shown in Figure 6-2 of SNOS631E to maintain phase margin.
What is the thermal resistance (RθJA) of LMC6062IM in SOIC-8 package?
The junction-to-ambient thermal resistance RθJA for LMC6062IM in D (SOIC-8) package is 193°C/W, as specified in Section 5.5 of the datasheet. This value assumes standard JEDEC 2-layer board layout; actual performance improves with copper pour and thermal vias.
Is LMC6062IM suitable for photodiode transimpedance applications?
Yes - LMC6062IM is explicitly recommended for photodiode preamplifiers due to its 10fA typical input bias current, >10TΩ input resistance, and low input voltage noise (83nV/√Hz). For optimal performance, guard rings and low-leakage PCB layout per Section 6.3.1.1 are mandatory.
