Product details
Overview
MAX6043CAUT10-T from Maxim Integrated is a precision +10.0V voltage reference IC designed for high-accuracy analog signal conditioning in demanding measurement and conversion systems. It delivers 0.5% initial accuracy, 65ppm/°C max temperature coefficient, and operates from +12V to +40V input over –40°C to +125°C - enabling use in automotive sensor front-ends and industrial data acquisition where stable reference voltage is critical.
For engineers reviewing the MAX6043CAUT10-T datasheet, MAX6043CAUT10-T pinout, MAX6043CAUT10-T application, or MAX6043CAUT10-T equivalent, key selection criteria include its 10V output tolerance, SOT23-6 package footprint, load regulation performance (±900 ppm/mA sinking), stability without output capacitors, and compatibility with high-resolution ADCs requiring low-drift references.
Technical Context
The MAX6043CAUT10-T uses bandgap-based architecture with curvature-correction circuitry to achieve low thermal drift across its full automotive temperature range. Its dual-output topology (OUTF/OUTS) enables Kelvin sensing to reject PCB trace resistance errors, supporting precision applications where layout-induced voltage drop must be minimized.
It features short-circuit protection (60mA sourcing limit), operates without mandatory output bypass capacitance, and maintains stability with capacitive loads up to 100µF. The device draws only 390–650µA quiescent current across temperature, making it suitable for battery-backed instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | +10.000V ±0.5% (±50mV) at TA = +25°C; supports 12-bit to 16-bit ADC accuracy over full temp range |
| Tempco | 65ppm/°C max (–40°C to +125°C); ensures ≤±780ppm total drift across operating range |
| Supply Range | +12.0V to +40.0V input; minimum headroom of 2.0V at 10mA load per typical curves |
| Load Regulation | ±900ppm/mA (sinking), ±170ppm/mA (sourcing); critical for dynamic load rejection in DAC buffer circuits |
| Quiescent Current | 390–650µA (–40°C to +125°C); enables >1-year operation on coin-cell batteries in low-duty-cycle sensors |
| Output Noise | 19µVP-P (0.1Hz–10Hz), 30µVRMS (10Hz–1kHz); low enough for 18-bit SAR ADC reference use |
| Turn-On Settling | 390µs to 0.05% of final value (COUT = 50pF); defines minimum sampling delay after power-up |
Pinout & Package
MAX6043CAUT10-T is housed in a RoHS-compliant 6-pin SOT23 package (outline U6FH-6, land pattern 90-0175), measuring 2.9mm × 1.6mm × 1.1mm. Pins 1 and 3 are internally connected and must remain unconnected on PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3 | I.C. (Internally Connected) | No external connection required; internal tie-off only - floating or tied pins cause no functional impact |
| 2 | GND | Analog ground reference; must be low-impedance path to system AGND to minimize noise coupling |
| 4 | IN | Positive supply input; accepts +12V to +40V; decoupling with 0.1µF ceramic near pin improves line transient immunity |
| 5 | OUTF | Force output; drives load directly; connect to OUTS within 1mm to enable Kelvin sensing and eliminate trace IR drop |
| 6 | OUTS | Sense input; provides feedback to internal amplifier; forms remote-sensing loop with OUTF for <100µV error at load |
Key Features
| Feature | Design Value |
|---|---|
| Kelvin force/sense outputs (OUTF/OUTS) | Enables remote sensing to cancel PCB trace resistance effects - critical for ±0.1% system-level accuracy |
| No output capacitor required for stability | Eliminates 1–10µF tantalum/ceramic at output, saving board space and reducing BOM count in compact modules |
| Stable with 0–100µF capacitive loads | Supports direct connection to noisy digital supplies or large local decoupling without oscillation risk |
| Short-circuit protected (60mA limit) | Prevents latch-up or damage during test, probe contact, or accidental wiring faults in production environments |
| Automotive-grade temp range (–40°C to +125°C) | Qualified for under-hood and chassis-mounted applications without derating or thermal management overhead |
Applications
| Automotive Sensor Signal Conditioning | Industrial Data Acquisition Front-End |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5010IDR | 10ppm/°C max tempco, 0.05% initial accuracy, SO-8 package, 3.6mA quiescent current | Higher accuracy and lower drift, but larger footprint and 11× higher supply current | Select when absolute stability dominates size/power constraints - e.g., lab-grade instruments |
| ADR4510BRZ | 3ppm/°C max tempco, 0.02% initial accuracy, SO-8 package, 950µA quiescent current, 10V output | Superior long-term stability (15ppm/1000hr vs. 150ppm/1000hr) and lower noise (12µVP-P) | Choose for metrology or calibration equipment where 18-bit+ performance justifies cost and size premium |
Compared with REF5010IDR and ADR4510BRZ, the MAX6043CAUT10-T trades higher tempco and accuracy for ultra-low quiescent current, SOT23-6 footprint, and Kelvin sensing - making it optimal for space-constrained, battery-powered, or automotive applications where moderate accuracy suffices.

FAQ
What is the maximum input voltage for MAX6043CAUT10-T?
The MAX6043CAUT10-T supports an absolute maximum input voltage of +42V, with recommended operating range from +12.0V to +40.0V. Operation above +40V risks exceeding absolute maximum ratings and may degrade long-term reliability - always maintain ≥2V headroom above 10V output under full load per typical curves.
Does MAX6043CAUT10-T require an output capacitor?
No, the MAX6043CAUT10-T does not require an output capacitor for stability and remains stable with capacitive loads from 0 to 100µF. An output capacitor is optional and used only to improve transient response - never required for basic functionality or loop stability.
What is the meaning of OUTF and OUTS pins on MAX6043CAUT10-T?
OUTF is the force output that drives the load, while OUTS is the sense input that provides feedback to the internal amplifier. Connecting OUTF to OUTS as close as possible to the MAX6043CAUT10-T enables Kelvin sensing, eliminating voltage drop errors in PCB traces or connectors for high-accuracy applications.
Can MAX6043CAUT10-T sink current?
Yes, the MAX6043CAUT10-T can sink up to –0.6mA while maintaining regulation. Its load regulation specification includes sinking behavior (±900ppm/mA), and it features short-circuit protection limiting sink current to –2mA if output is pulled below GND - ensuring safe operation in bidirectional reference configurations.
What is the top-marking code for MAX6043CAUT10-T?
The top-marking code for MAX6043CAUT10-T is ABDZ, laser-trimmed on the SOT23 package. This marking identifies the 10V output, C-grade accuracy (0.5%), and automotive temperature range - matching the ordering information table in the official MAX6043 datasheet Rev 2.
