Product details
Overview
LM10CLN/NOPB from Texas Instruments is a monolithic linear IC integrating a precision voltage reference and an independent operational amplifier, designed for ultra-low-voltage single-supply operation down to 1.2 V and up to 6.5 V. It delivers 20–70 V/mV large-signal voltage gain, ±20-mA output drive capability, and 200-mV minimum reference output with 0.003%/°C drift. It is used in battery-level indicators and thermocouple transmitters where supply headroom is constrained.
For engineers reviewing the LM10CLN/NOPB datasheet, LM10CLN/NOPB pinout, LM10CLN/NOPB application, or LM10CLN/NOPB equivalent, this page provides verified electrical parameters, package-specific terminal mapping, real-world use scenarios, and two confirmed alternative parts for low-voltage reference-amplifier applications requiring <6.5-V operation and floating-mode capability.
Technical Context
The LM10CLN/NOPB implements a dual-function architecture: a trimmed bandgap reference buffer (200 mV nominal output) and a high-output-drive op amp sharing no internal bias paths-enabling true floating-mode operation. Its input common-mode range extends from V− to (V+ − 0.85 V), and it supports shunt-regulator configurations via feedback sense at 190–211 mV.
Unlike standard op amps, the LM10CLN/NOPB uses complementary PNP/NPN output stages with thermal overload protection, allowing rail-to-rail swing within 15 mV under light load and ±20-mA sourcing/sinking at ±0.4-V saturation. Its reference section features second-order nonlinearity compensation for improved temperature stability over conventional references.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 6.5 V - enables direct operation from single Li-ion cell or low-voltage industrial rails without boost circuitry. |
| Reference Output Voltage | 190–211 mV - stable, low-drift buffered reference usable as precision shunt regulator threshold or bias source. |
| Op Amp Large-Signal Gain | 20–70 V/mV - sufficient for closed-loop gain ≥1000 in sensor signal conditioning with minimal external components. |
| Input Offset Voltage | 0.5–4 mV (max) - supports accurate DC-coupled amplification in battery monitoring and thermocouple interfaces. |
| Supply Current | 280–570 μA - ultra-low quiescent draw suitable for always-on portable instrumentation with multi-year battery life. |
| Reference Drift | 0.003%/°C - ensures <±0.2% reference error over 0°C to 70°C operating range (LM10CL grade). |
| Input Bias Current | 12–30 nA (typ) - permits high-impedance sensor interfacing (e.g., thermistors, pH electrodes) without significant loading error. |
Pinout & Package
LM10CLN/NOPB is supplied in an 8-pin PDIP package (9.81 mm × 6.35 mm body size) with through-hole mounting. Pin functions are electrically identical to the SDIP variant and validated per TI SNOSBH4E Rev E.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V− (Pin 4) | Negative supply terminal | Reference and op amp ground node; must be connected directly to low-impedance return path to avoid reference regulation error. |
| Op Amp Input (–) (Pin 2) | Inverting input | Differential input node for op amp; common-mode range extends to V−, enabling true single-supply operation. |
| Op Amp Input (+) (Pin 3) | Noninverting input | High-impedance input for sensor signals or reference-derived thresholds; bias current ≤30 nA minimizes offset error. |
| Op Amp Output (Pin 6) | Amplifier output | Capable of ±20-mA drive into loads; swings within 15 mV of V− or V+ under light load for rail-to-rail signal delivery. |
| Reference Output (Pin 1) | Reference voltage source | 200-mV nominal buffered output; used directly as shunt regulator reference or as precision bias for external circuitry. |
| Reference Feedback (Pin 8) | Reference sense input | Connects to shunt resistor node in regulator configurations; senses 190–211 mV to maintain regulated output. |
| V+ (Pin 7) | Positive supply terminal | Accepts 1.2–6.5 V; supplies both reference and op amp sections independently-no shared bias dependency. |
| Balance (Pin 5) | Offset null adjustment | Allows external trimming of op amp input offset voltage using 10-kΩ potentiometer for <1-mV residual error. |
Key Features
| Feature | Design Value |
|---|---|
| Floating-mode operation | Op amp output tied to V+ disables PNP stage, enabling operation powered solely by signal-line voltage drop-ideal for 2-wire transmitters. |
| Ultra-low minimum supply | 1.2 V operation allows direct interface with depleted alkaline or single LiFePO₄ cells without voltage boosting. |
| Integrated reference + op amp | Monolithic integration eliminates inter-device matching errors and PCB layout sensitivity between reference and amplifier sections. |
| Thermal overload protection | Internal thermal limiting prevents destructive failure during sustained short-circuit or high-power dissipation conditions. |
| Second-order reference compensation | Eliminates curvature in reference vs. temperature curve, delivering flat 0.003%/°C drift across 0°C to 70°C. |
Applications
| Battery-Level Indicators | Thermocouple Transmitters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar reference-amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM10CN/NOPB | Wider supply range (1.2–40 V), higher max offset voltage (5 mV), 0.003%/°C reference drift, 0°C–70°C temp range. | Supports high-voltage regulator designs but lacks low-voltage optimization; less suitable for sub-2-V battery monitoring. | Select LM10CN/NOPB when system supply exceeds 6.5 V or requires full 40-V tolerance; LM10CLN/NOPB preferred for strict low-voltage portables. |
| MAX4040ASA+ | Single 2.048-V reference + rail-to-rail op amp; 1.8–5.5 V supply; 25-μA supply current; no floating-mode support. | Optimized for ultra-low-power microcontroller interfaces-not suitable for 2-wire transmitters or shunt regulation. | Choose MAX4040ASA+ only for low-quiescent, fixed-reference applications where floating operation and shunt regulation are unnecessary. |
Compared with LM10CN/NOPB, LM10CLN/NOPB trades maximum supply voltage for tighter low-voltage performance and guaranteed 1.2-V start-up; versus MAX4040ASA+, it offers integrated shunt-regulator functionality and true floating-mode operation at the cost of higher quiescent current-making it uniquely suited for 2-wire industrial sensors and battery-critical portable systems.

FAQ
What is the minimum operating voltage for LM10CLN/NOPB?
The LM10CLN/NOPB is specified to operate down to 1.2 V supply voltage, with functional operation possible as low as 1.1 V per TI SNOSBH4E. This enables direct use with partially discharged alkaline or single LiFePO₄ cells without voltage boosting. The 1.2 V lower limit applies across its 0°C to 70°C commercial temperature range.
Can LM10CLN/NOPB operate in floating mode, and how is it configured?
Yes, LM10CLN/NOPB supports floating-mode operation: connect the op amp output (Pin 6) to V+ (Pin 7) to disable the PNP output stage. In this configuration, the device draws only quiescent supply current (280–570 μA) when idle and delivers signal current on the same line used for power-enabling true 2-wire transmitter designs without local ground reference.
What is the purpose of the Balance pin (Pin 5) on LM10CLN/NOPB?
The Balance pin (Pin 5) provides access to the op amp's internal offset-null network. Connecting a 10-kΩ potentiometer between Pins 1 (Ref Out) and 8 (Ref Feedback), with wiper to Pin 5, allows manual trimming of input offset voltage to <1 mV. This is critical for precision DC-coupled applications like thermocouple amplification where residual offset directly impacts measurement accuracy.
How does the reference section of LM10CLN/NOPB differ from standard bandgap references?
The LM10CLN/NOPB reference uses second-order nonlinearity compensation to flatten the temperature vs. voltage curve-achieving 0.003%/°C drift over 0°C to 70°C. Unlike basic bandgap references exhibiting parabolic curvature, this compensation eliminates "bowing," ensuring consistent regulation across temperature without external calibration or software correction.
Is LM10CLN/NOPB pin-compatible with other LM10 variants like LM10CN/NOPB?
Yes, LM10CLN/NOPB is pin-compatible with all 8-pin PDIP variants of the LM10 family-including LM10CN/NOPB and LM10BN/NOPB-as confirmed by TI's pin function tables in SNOSBH4E. All share identical pin numbering, terminal roles, and mechanical footprint; differences are limited to electrical specifications (supply range, drift, offset) and temperature grading-not physical or logical connectivity.
