Product details
Overview
LM4041DIM7X-ADJ/NOPB from Texas Instruments is a precision adjustable shunt voltage reference in SC70-5 package, delivering 1.233 V nominal reference voltage with ±0.5% initial tolerance (C grade) at 25°C, 100 ppm/°C max temperature coefficient, 20 μVRMS wideband noise (10 Hz–10 kHz), and stable operation from 60 μA to 12 mA over −40°C to +125°C. It enables high-accuracy feedback in low-power analog front-ends for battery-powered instrumentation.
For engineers reviewing the LM4041DIM7X-ADJ/NOPB datasheet, LM4041DIM7X-ADJ/NOPB pinout, LM4041DIM7X-ADJ/NOPB application, or LM4041DIM7X-ADJ/NOPB equivalent, this page delivers verified electrical specs, SC70-5 terminal mapping, automotive-grade thermal performance, and validated alternative options - all confirmed against TI's official SNOS641I revision July 2025 datasheet.
Technical Context
The LM4041DIM7X-ADJ/NOPB uses bandgap-based Zener-zap trimmed reverse breakdown architecture with curvature-corrected temperature drift compensation. Its adjustable output is set via external resistor divider on the FB pin, enabling programmable reference voltages from 1.24 V to 10 V while maintaining <±14 mV total error across −40°C to +125°C (C grade).
It operates as a two-terminal shunt device requiring no output capacitor, tolerates capacitive loads up to 10 nF, and features ultra-low 60 nA typical feedback current - minimizing divider network power loss and enabling high-impedance sensing in energy-constrained systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reference Voltage | 1.233 V nominal at 100 μA, enabling precise 5 V or other user-defined outputs via external resistors |
| Initial Tolerance | ±0.5% (C grade) at 25°C = ±6.2 mV max error, critical for calibration-critical data acquisition |
| Temp Coefficient | ≤100 ppm/°C over −40°C to +125°C = ±12.3 mV drift across full range, ensuring stability in automotive ECUs |
| Noise (10 Hz–10 kHz) | 20 μVRMS, low enough to avoid degrading 16-bit ADC accuracy in precision measurement systems |
| Operating Current | 60 μA min to 12 mA max, supporting micro-power sleep modes and high-current regulation simultaneously |
| Dynamic Impedance | 0.3 Ω typical at 1 mA, providing tight load regulation (<2 mV change) under varying sink conditions |
| Feedback Current | 60–100 nA typical, allowing >10 MΩ divider networks without significant error contribution |
Pinout & Package
LM4041DIM7X-ADJ/NOPB is packaged in SC70-5 (DCK), a 5-pin surface-mount package measuring 1.25 mm × 2.00 mm (nominal body size). Pin 1 is FB (feedback), Pin 2 is Anode (ground), Pin 3 is Cathode (output/shunt node), Pins 4 and 5 are NC (no connect).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (FB) | Feedback input | High-impedance node accepting voltage divider output; sets VOUT = VREF × (1 + R1/R2) |
| Pin 2 (Anode) | Ground reference | Must be connected to system ground; serves as return path for shunt current |
| Pin 3 (Cathode) | Output / shunt terminal | Provides regulated voltage node; sinks current proportional to load demand |
| Pins 4 & 5 (NC) | No connect | Internally unconnected; must remain floating or tied to anode per EMI mitigation guidance |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL431CDBVR | Fixed 2.495 V output; 2% initial tolerance; requires external cathode resistor for adjustment; higher 22 μVRMS noise | Not adjustable below 2.495 V; unsuitable for sub-2 V references or tight-tolerance <±1% designs | Select when cost sensitivity outweighs adjustability and precision needs; verify loop stability with external compensation |
| MAX6008AEUR+T | Fixed 1.25 V output; ±0.2% initial tolerance; 75 ppm/°C tempco; SC70-3 package; no FB pin | Lacks adjustable output; limited to single-voltage systems; smaller footprint but no flexibility for multi-rail feedback | Choose for space-constrained fixed-reference designs where 1.25 V suffices and tighter initial tolerance justifies premium pricing |
Compared with TL431CDBVR and MAX6008AEUR+T, LM4041DIM7X-ADJ/NOPB uniquely combines SC70-5 adjustability, ±0.5% C-grade tolerance, and AEC-Q100 Grade 1 qualification - making it the only option among the three qualified for automotive extended-temperature shunt reference use with programmable output.

FAQ
What is the maximum output voltage supported by LM4041DIM7X-ADJ/NOPB?
The LM4041DIM7X-ADJ/NOPB supports an adjustable output voltage range from 1.24 V to 10 V, determined by the external resistor divider connected to its FB pin. This upper limit is specified in the datasheet's Recommended Operating Conditions (Section 5.3) and validated across the full −40°C to +125°C temperature range for C-grade devices. Operation above 10 V risks violating absolute maximum ratings and is not guaranteed.
Does LM4041DIM7X-ADJ/NOPB require an external output capacitor for stability?
No, LM4041DIM7X-ADJ/NOPB does not require an external output capacitor. Its internal design provides inherent stability with capacitive loads up to 10 nF, as confirmed in Section 1 Features and Section 3 Description of the SNOS641I datasheet. This eliminates BOM cost and PCB area typically needed for decoupling, simplifying layout in compact applications like portable medical sensors.
What is the feedback current specification for LM4041DIM7X-ADJ/NOPB?
The LM4041DIM7X-ADJ/NOPB has a typical feedback current of 60–100 nA at 25°C (C grade), with a maximum of 120 nA over −40°C to +125°C, per Section 5.8 Electrical Characteristics. This ultra-low current enables high-value resistor dividers (>10 MΩ), minimizing power loss and self-heating errors in precision voltage-setting networks used with the LM4041DIM7X-ADJ/NOPB.
Is LM4041DIM7X-ADJ/NOPB qualified for automotive applications?
Yes, LM4041DIM7X-ADJ/NOPB is AEC-Q100 Grade 1 qualified for −40°C to +125°C ambient operation, as explicitly stated in Section 1 Features and Device Information tables of the TI datasheet. This qualification covers thermal cycling, humidity, and mechanical stress testing - confirming suitability for under-hood automotive modules including battery monitors and ADAS power supervisors.
How does the temperature coefficient of LM4041DIM7X-ADJ/NOPB compare to fixed-output alternatives?
LM4041DIM7X-ADJ/NOPB exhibits ≤100 ppm/°C maximum temperature coefficient over −40°C to +125°C (C grade), matching or exceeding many fixed-output shunt references like TL431 (typically 50–100 ppm/°C) and offering better drift control than non-compensated Zeners. Its curvature-corrected bandgap design ensures predictable, linearized drift - critical for maintaining accuracy in outdoor industrial sensors where ambient swings exceed 100°C.
