Product details
Overview
MAX6043AAUT41-T from Maxim Integrated is a precision 4.096V voltage reference IC in SOT23-6 package, delivering ±0.06% initial accuracy, 15ppm/°C max temperature coefficient, and 6.6µVP-P (0.1Hz–10Hz) output noise. It operates from 6.1V to 40V input, sources up to 10mA, and targets high-resolution ADC/DAC biasing in automotive-grade systems.
For engineers reviewing the MAX6043AAUT41-T datasheet, MAX6043AAUT41-T pinout, MAX6043AAUT41-T application, or MAX6043AAUT41-T equivalent, key selection criteria include its 4.096V output optimized for 12-bit and 16-bit data converters, no-output-capacitor stability up to 100µF, and guaranteed operation across –40°C to +125°C.
Technical Context
The MAX6043AAUT41-T uses bandgap-based architecture with proprietary curvature-correction circuitry and laser-trimmed thin-film resistors to achieve low drift and high DC accuracy. Its dual-output topology (OUTF/OUTS) enables Kelvin sensing for load regulation immunity.
It features internal short-circuit protection (60mA sourcing limit), operates without mandatory output bypass capacitors, and maintains stability under capacitive loads from 0 to 100µF - eliminating board area overhead in space-constrained designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±0.06% (±2.46mV) at +25°C - matches common 12-bit DAC/ADC full-scale scaling. |
| Tempco | 15ppm/°C max (–40°C to +125°C) - ensures ≤±0.75 LSB error over temperature for 16-bit systems. |
| Noise (0.1–10Hz) | 6.6µVP-P - supports <18-bit effective resolution in precision measurement front-ends. |
| Supply Range | +6.1V to +40V - enables direct use with unregulated industrial or automotive rails. |
| Load Current | Sources 10mA / sinks 0.6mA - drives typical SAR ADC reference inputs and small buffer stages. |
| Quiescent Current | 320µA typ at +25°C - enables multi-year battery life in portable instrumentation. |
| Capacitive Load Stability | Stable with 0–100µF - eliminates need for output capacitor in most applications, reducing BOM count. |
Pinout & Package
MAX6043AAUT41-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, rated for –40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3 | I.C. (Internally Connected) | No external connection required; internal bond wire stubs - must remain floating. |
| 2 | GND | Analog ground reference; requires low-impedance return path to minimize noise coupling. |
| 4 | IN | Positive supply input; accepts 6.1V–40V; decoupling with 0.1µF ceramic recommended near pin. |
| 5 | OUTF | Force output - delivers regulated voltage; connect directly to OUTS trace within 1mm for Kelvin sensing. |
| 6 | OUTS | Sense input - provides feedback to internal amplifier; ties to load-side of reference divider or ADC REF+. |
Key Features
| Feature | Design Value |
|---|---|
| 4.096V Output | Exact match for 12-bit (4096-step) and 16-bit (65536-step) converter full-scale scaling - eliminates gain calibration. |
| Kelvin Force/Sense Outputs | OUTF/OUTS separation rejects IR drop in PCB traces and improves load regulation to ±70ppm/mA. |
| No Output Capacitor Required | Reduces component count and layout area - critical for compact sensor modules and portable test equipment. |
| Automotive Temperature Range | –40°C to +125°C operation qualified per AEC-Q100 - suitable for engine control, ADAS power domains, and battery monitoring. |
| Short-Circuit Protection | 60mA current limit on OUTF prevents damage during accidental shorts - enhances field reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5040IDR | 4.096V, 3ppm/°C max tempco, 0.05% initial accuracy, SOIC-8 package | Lower drift but larger footprint and higher quiescent current (950µA) | Select when ultra-low drift dominates over size/power constraints |

FAQ
What is the output voltage tolerance of the MAX6043AAUT41-T at room temperature?
The MAX6043AAUT41-T guarantees ±0.06% initial accuracy at +25°C, corresponding to ±2.46mV around its nominal 4.096V output. This specification is verified across 100% production testing and applies before thermal cycling or long-term drift effects.
Does the MAX6043AAUT41-T require an output bypass capacitor for stability?
No - the MAX6043AAUT41-T is internally compensated and stable with capacitive loads from 0 to 100µF. An output capacitor is optional and only recommended when improving transient response to large load steps; the device functions reliably without one.
How does the OUTF/OUTS pin configuration improve reference accuracy in the MAX6043AAUT41-T?
The MAX6043AAUT41-T uses separate force (OUTF) and sense (OUTS) outputs to implement Kelvin sensing. By routing OUTS directly to the load point, the internal amplifier compensates for voltage drop across PCB traces or interconnects - maintaining regulation accuracy independent of load current-induced IR loss.
What is the maximum allowable input voltage for the MAX6043AAUT41-T?
The absolute maximum input voltage for the MAX6043AAUT41-T is +42V, but the specified operating range is +6.1V to +40V. Operation below 6.1V may cause dropout or regulation failure, especially under load or at elevated temperatures.
Can the MAX6043AAUT41-T be used in automotive applications?
Yes - the MAX6043AAUT41-T is qualified for the automotive temperature range (–40°C to +125°C) and packaged in RoHS-compliant SOT23. It meets requirements for engine control units, battery management systems, and ADAS sensors where precision, low noise, and thermal stability are critical.
