Product details
Overview
LMC6001AIN/NOPB from Texas Instruments is an ultra-low-input-current CMOS operational amplifier designed for high-impedance signal conditioning in electrometer-grade applications. It delivers 25 fA maximum input bias current (100% tested at 25°C), 22 nV/√Hz input voltage noise, 750 μA supply current, and rail-to-rail output swing - enabling precision amplification of photodiode, ion detector, and pH probe signals with minimal leakage or added noise.
For engineers reviewing the LMC6001AIN/NOPB datasheet, LMC6001AIN/NOPB pinout, LMC6001AIN/NOPB application, or LMC6001AIN/NOPB equivalent, key selection criteria include verified 25-fA input current limit, 0.13 fA/√Hz input current noise, guaranteed operation from 4.5 V to 15.5 V supply, ±2000-V HBM ESD rating, and compatibility with transimpedance configurations up to 2000 MΩ feedback resistance.
Technical Context
The LMC6001AIN/NOPB uses a proprietary CMOS input stage with tightly controlled molding compound to achieve industry-leading 25-fA input current specification - verified via triple testing within the first minute of power-up to reject units exhibiting drift. Its internal integrator-based output stage eliminates conventional push-pull buffers, enabling rail-to-rail swing while maintaining low output impedance and high open-loop gain.
This architecture supports stable operation with capacitive loads when paired with external compensation (e.g., pull-up resistor or feed-forward network), and incorporates latch-up prevention circuitry rated for 100-mA I/O surge current. The device operates across –40°C to +85°C junction temperature with no minimum load requirement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Bias Current | 25 fA max (100% tested at 25°C); enables accurate measurement of picoamp-level currents from high-Z sources like photodiodes or ion detectors. |
| Input Current Noise | 0.13 fA/√Hz at 1 kHz; contributes negligible noise when amplifying signals from sources >10 MΩ. |
| Supply Current | 750 μA typical; supports battery-powered portable instrumentation without compromising input performance. |
| Input Voltage Noise | 22 nV/√Hz at 1 kHz; ensures superior signal-to-noise ratio vs. JFET-input electrometer amps in low-frequency sensing. |
| Gain-Bandwidth Product | 1.3 MHz; sufficient for DC–100 kHz transimpedance amplification with stability margins maintained up to 100 pF load. |
| ESD Rating | ±2000 V HBM; protects against handling damage during PCB assembly and field service in lab-grade equipment. |
| Common-Mode Range | 0 V to V+ − 1.9 V (at 25°C); supports single-supply operation with inputs near ground in pH probe and leakage test circuits. |
| Output Swing | Rail-to-rail (e.g., 0.17 V to 4.87 V on 5 V supply); maximizes dynamic range for low-voltage microcontroller ADC interfacing. |
Pinout & Package
LMC6001AIN/NOPB is supplied in an 8-pin PDIP package (9.81 mm × 6.35 mm) with through-hole mounting. The package includes internal ESD protection diodes and is qualified for industrial temperature operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN (Pin 3) | Noninverting Input | High-impedance CMOS node; connects directly to sensor anode or guarded trace in electrometer designs. |
| –IN (Pin 2) | Inverting Input | High-impedance CMOS node; used for feedback connection in transimpedance or unity-gain buffer configurations. |
| OUTPUT (Pin 6) | Amplifier Output | Rail-to-rail capable; drives ADC inputs, analog meters, or downstream signal chains without level-shifting. |
| V+ (Pin 7) | Positive Supply | Accepts 4.5 V to 15.5 V; powers internal bias networks and output stage; requires local 0.1-μF ceramic decoupling. |
| V– (Pin 4) | Negative Supply | Ground or negative rail (e.g., –5 V); establishes reference for dual-supply operation; must be stable and low-noise. |
| NC (Pins 1, 5, 8) | No Connection | Unbonded die pads; must remain unconnected and unstubbed to avoid parasitic coupling or leakage paths. |
| CAN (Pin 8, TO-99 only) | Case Connection | Not present in PDIP variant; omitted from LMC6001AIN/NOPB pinout per datasheet Pin Functions table. |
Key Features
| Feature | Design Value |
|---|---|
| 100% tested input current | Guarantees ≤25 fA at 25°C via triple-in-minute screening - critical for production-critical electrometer calibration. |
| Rail-to-rail output stage | Delivers full supply swing without external level-shifting, preserving SNR in low-voltage battery systems. |
| Ultra-low current noise | 0.13 fA/√Hz enables <0.01 dB gain error at 1000 MΩ source impedance - essential for long-interval integrators. |
| Integrated ESD protection | ±2000 V HBM rating eliminates need for external TVS diodes in lab instrument front-end stages. |
| Latch-up immunity | Withstands 100-mA transient current on I/O pins - prevents failure during probe insertion or ESD events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-input-current amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC6078IS8#PBF | Max input bias current = 1 fA (typ), higher supply current (1.1 mA), dual-channel, SO-8 package. | Better input current spec but higher power; suited for multi-channel low-leakage monitoring where board space is constrained. | Select LTC6078IS8#PBF when sub-10-fA performance is mandatory and dual-channel integration reduces system component count. |
| OPA128SM | Max input bias current = 40 fA (typ), JFET input, TO-99 metal can, higher voltage noise (15 nV/√Hz). | Superior EMI immunity due to hermetic metal package; preferred in high-noise industrial environments despite higher Vn. | Select OPA128SM when operating near RF sources or in unshielded enclosures where electromagnetic interference dominates noise budget. |
Compared with LTC6078IS8#PBF and OPA128SM, the LMC6001AIN/NOPB offers the lowest cost-per-channel PDIP solution with verified 25-fA limit and integrated ±2000-V HBM protection - making it optimal for single-channel, cost-sensitive electrometer designs requiring production traceability.

FAQ
What is the maximum verified input bias current for LMC6001AIN/NOPB?
The LMC6001AIN/NOPB has a maximum input bias current of 25 fA at 25°C, 100% tested and screened via triple measurement within the first minute of operation. Units exceeding this limit - or showing drift during initial stabilization - are rejected. This specification is confirmed in Section 6.5 of the SNOS694I datasheet for the LMC6001AI grade.
Does LMC6001AIN/NOPB support single-supply operation?
Yes, LMC6001AIN/NOPB supports true single-supply operation from 4.5 V to 15.5 V. Its input common-mode range extends from 0 V to V+ − 1.9 V (at 25°C), and output swings rail-to-rail - enabling use in battery-powered pH probes and handheld field instruments without negative rails.
How does LMC6001AIN/NOPB achieve stability with high-value feedback resistors?
LMC6001AIN/NOPB maintains stability with feedback resistors up to 2000 MΩ by minimizing input capacitance sensitivity. TI recommends guarding the input traces and adding a feedback capacitor (Cf) such that R1CIN ≤ R2Cf. This compensates for phase margin loss caused by photodiode or PCB parasitics, as detailed in Section 8.1.1 of the datasheet.
Is LMC6001AIN/NOPB pin-compatible with other LMC6001 variants?
Yes, LMC6001AIN/NOPB shares identical 8-pin PDIP pinout and electrical behavior with LMC6001BIN/NOPB and LMC6001CIN/NOPB. Differences lie only in input current grading (25 fA / 4000 fA / 4000 fA max), not pin function or package footprint - allowing drop-in replacement where performance margins permit.
What thermal derating applies to LMC6001AIN/NOPB in PDIP package?
LMC6001AIN/NOPB in PDIP has a junction-to-ambient thermal resistance (RθJA) of 100°C/W. At 85°C ambient and 750 μA supply current (≈11 mW dissipation), junction temperature rises ~1.1°C above ambient - well within the 150°C absolute maximum. No derating is required below 100°C ambient per Section 6.4 of the datasheet.
