Product details
Overview
LMC6041IN/NOPB from Texas Instruments is a single-channel, micropower CMOS operational amplifier optimized for ultra-low-input-current, rail-to-rail output, and single-supply operation (4.5V–15V). It delivers 2 fA typical input bias current, 10 µA supply current per amplifier, and output swing within 30 mV of both rails at 5V supply - enabling precision signal conditioning in battery-powered pH probes, photodiode preamplifiers, and piezoelectric charge amplifiers.
For engineers reviewing the LMC6041IN/NOPB datasheet, LMC6041IN/NOPB pinout, LMC6041IN/NOPB application, or LMC6041IN/NOPB equivalent, key selection criteria include verified 2 fA input leakage, guaranteed rail-to-rail output swing under 25 kΩ load, −40°C to +85°C operating range, and SOIC-8 package compatibility with legacy low-power analog designs.
Technical Context
The LMC6041IN/NOPB employs TI's double-poly silicon-gate CMOS process to achieve ultra-low input leakage while maintaining stability across capacitive loads and wide supply ranges. Its input stage includes ground-referenced common-mode range and high-impedance (>10 TΩ) differential inputs, eliminating need for external pulldown resistors in single-supply configurations.
Internal compensation ensures stable unity-gain operation with up to 100 pF capacitive load when using recommended layout practices. The device supports true rail-to-rail output sourcing/sinking (≥15 mA short-circuit current) without phase reversal or latch-up, making it suitable for direct interfacing with ADCs and low-voltage logic in portable instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Bias Current | 2 fA typical - enables femtoampere-level current measurement in photodiode and ion-sensing applications without significant error. |
| Supply Current | 14–26 µA at 5V - supports multi-year battery life in always-on sensor nodes and portable analyzers. |
| Rail-to-Rail Output | Swings to within 30 mV of V− and 13 mV of V+ at 100 kΩ load - preserves full dynamic range for 12-bit+ ADC interfacing. |
| Gain Bandwidth Product | 75 kHz - sufficient for DC–10 kHz sensor signal conditioning including pH, temperature, and pressure transducers. |
| Input Common-Mode Range | Includes ground (V−) and extends to (V+) − 2.3 V - allows direct sensing of 0–5 V industrial signals without level-shifting. |
| CMRR | 75 dB minimum - rejects power supply ripple and noise in single-supply battery systems with shared ground references. |
| ESD Rating | ±500 V HBM - meets standard handling requirements for lab and production environments without special ESD controls. |
Pinout & Package
LMC6041IN/NOPB is packaged in an 8-pin PDIP (Plastic Dual In-line Package), pin-compatible with industry-standard SOIC-8 footprints via adapter or board redesign. Thermal resistance RθJA is 101.0°C/W, supporting operation up to +85°C ambient with minimal derating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8 | No Connection (NC) | Must remain unconnected; floating or tied to ground degrades input leakage performance. |
| 2 | Inverting Input (−IN) | Differential input node with 2 fA bias current; requires guarded PCB trace to maintain femtoampere integrity. |
| 3 | Noninverting Input (+IN) | High-impedance input referenced to system ground; compatible with zero-bias transducer interfaces. |
| 4 | Negative Supply (V−) | Ground reference for single-supply operation; must be connected directly to PCB ground plane. |
| 6 | Output (OUT) | Rail-to-rail voltage source capable of sourcing/sinking ≥15 mA; drives 25 kΩ loads with <0.1% gain error. |
| 7 | Positive Supply (V+) | Primary power rail (4.5–15 V); decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low input bias current | 2 fA typical - enables accurate measurement of nanoampere-level photocurrents and electrochemical sensor outputs. |
| Rail-to-rail output swing | Within 30 mV of both rails at 100 kΩ - maximizes usable ADC input range without external level-shifting circuitry. |
| Single-supply operation | 4.5V–15V range with input common-mode including ground - eliminates dual-rail supplies in portable pH meters and smoke detectors. |
| High input impedance | >10 TΩ - prevents loading of high-Z sources like glass pH electrodes and piezoelectric accelerometers. |
| Stable with capacitive loads | Supports ≤100 pF direct capacitive loading - simplifies anti-aliasing filter design without external isolation resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC1050CN8#PBF | Higher input bias current (25 pA), wider supply range (±1.5V to ±18V), no rail-to-rail output. | Requires dual supply; less suitable for single-supply pH buffers but better for bipolar sensor front-ends. | Select when bipolar operation and higher slew rate (0.5 V/µs) outweigh ultra-low-leakage needs. |
| MAX406AESA+ | Lower quiescent current (3.5 µA), same 2 fA input bias, but only 50 kHz GBW and limited to 5.5V max supply. | Optimized for sub-1V coin-cell systems; insufficient for 12V industrial transducers or 15V smoke-detection rails. | Select for ultra-long-life medical wearables where supply voltage never exceeds 5.5V and bandwidth ≤20 kHz. |
Compared with LTC1050CN8#PBF and MAX406AESA+, the LMC6041IN/NOPB uniquely balances femtoampere input leakage, rail-to-rail output, and 4.5–15V single-supply flexibility - making it the only option that satisfies pH probe buffering, piezoelectric charge integration, and battery monitoring in one footprint without trade-offs in supply range or output swing.

FAQ
What is the maximum supply voltage for LMC6041IN/NOPB?
The LMC6041IN/NOPB supports a maximum supply voltage of 15 V for single-supply operation or ±7.75 V for dual-supply use. Absolute maximum rating is 16 V across V+ and V− pins. Exceeding this risks permanent damage, especially when output is shorted to V+ above 13 V. Always observe derating curves in Section 5.1 of the official datasheet for elevated temperature operation.
Does LMC6041IN/NOPB support rail-to-rail input?
No, the LMC6041IN/NOPB does not support rail-to-rail input. Its input common-mode range extends from V− (ground) to (V+) − 2.3 V at room temperature, and to (V+) − 2.5 V over −40°C to +85°C. This allows ground-referenced sensing but excludes direct connection to the positive rail without attenuation or level-shifting.
Can LMC6041IN/NOPB drive capacitive loads directly?
Yes, the LMC6041IN/NOPB can drive up to 100 pF capacitive loads stably in unity-gain configuration when proper PCB layout (guard rings, short traces) and decoupling (0.1 µF ceramic near V+ pin) are applied. For larger loads, external compensation - such as a series resistor between output and capacitor or a pullup to V+ - is required per Section 6.1.3 of the datasheet.
What is the typical input offset voltage of LMC6041IN/NOPB?
The LMC6041IN/NOPB has a typical input offset voltage of ±1 mV, with a maximum of ±3 mV at 25°C for the AI grade (LMC6041AI). Over the full −40°C to +85°C range, the maximum offset is ±3.3 mV. This low drift (1.3 µV/°C) ensures stable DC gain in pH buffers and thermopile amplifiers without frequent recalibration.
Is LMC6041IN/NOPB pin-compatible with other LMC604x variants?
No, LMC6041IN/NOPB is not pin-compatible with LMC6042 or LMC6044. While all share the same SOIC-8 or PDIP-8 package footprint for the single-channel (LMC6041) and dual-channel (LMC6042) versions, the LMC6044 uses a 14-pin SOIC/N package. Pin functions differ across variants - e.g., LMC6042 has dedicated IN+/IN−/OUT for two channels, whereas LMC6041 has only one set plus NC pins.
