Product details
Overview
MAX6071AAUT50+T from Analog Devices is a precision 5.0V series voltage reference IC in a 6-pin SOT23 package, delivering ±0.04% initial accuracy, 6ppm/°C max temperature drift (A grade), and ultra-low 4.8µVP-P 1/f noise (0.1Hz–10Hz) at 5V output. It sources/sinks ±10mA, operates from 5.2V to 5.5V input, and targets high-resolution ADC/DAC biasing in industrial process control systems.
For engineers reviewing the MAX6071AAUT50+T datasheet, MAX6071AAUT50+T pinout, MAX6071AAUT50+T application, or MAX6071AAUT50+T equivalent, key selection criteria include its 5.0V fixed output, A-grade drift spec, SOT23-6 thermal performance (θJA = 230°C/W), and enable-controlled low-power operation (150µA quiescent, 6µA shutdown).
Technical Context
The MAX6071AAUT50+T implements a bandgap-based series voltage reference with force-sense architecture: OUTF delivers regulated 5.0V output while OUTS provides remote sensing for load regulation correction, minimizing IR-drop errors. Its dual-ground structure (GNDF/GNDS) isolates filter and sense paths to preserve noise integrity.
Unlike the MAX6070, it omits the FILTER pin-eliminating external capacitor dependency for high-frequency noise suppression-and uses a simplified 6-pin SOT23 layout optimized for stability with 0.1–10µF capacitive loads. It achieves 80dB ripple rejection at 60Hz and 30µs turn-on settling to 0.01%.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±0.04% at +25°C - ensures direct compatibility with 5V ADC reference inputs without trimming. |
| Temp Drift (max) | 6ppm/°C (A grade) - limits full-scale error to ≤±75ppm over –40°C to +125°C industrial range. |
| Noise (0.1–10Hz) | 4.8µVP-P - enables 20-bit+ effective resolution in precision data acquisition systems. |
| Supply Current | 150µA typical - supports battery-powered instrumentation with <1mW total dissipation at 5.5V. |
| Load Current | ±10mA sourcing/sinking - drives 500Ω minimum load directly, eliminating need for external buffers. |
| Dropout Voltage | 60–150mV at 10mA - allows operation with only 5.2V input, easing LDO selection in 5V rail designs. |
| Ripple Rejection | 80dB at 60Hz - suppresses power-supply hum to <0.1% of reference output amplitude. |
Pinout & Package
Package: 6-pin SOT23 (U6+5/U6+5A), 2.9mm × 1.6mm × 1.1mm body, JEDEC MO-178AC compliant, θJA = 230°C/W on 4-layer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GNDF | Ground Force | Reference ground return for internal bandgap circuitry; must be tied to system ground near device. |
| 2 - GNDS | Ground Sense | Remote sense point for load ground connection; minimizes ground-path error in force-sense topology. |
| 3 - EN | Enable Input | Active-high digital control (VIH ≥ 0.7×VIN); enables 150µA operation or disables to 6µA shutdown current. |
| 4 - IN | Supply Input | Input voltage range 5.2–5.5V; dropout as low as 60mV enables tight-margin 5V system integration. |
| 5 - OUTS | Voltage Sense Output | Feedback node for remote sensing; connects directly to load ground to correct trace resistance errors. |
| 6 - OUTF | Voltage Force Output | Main 5.0V output; bypassed with 0.1–10µF capacitor to GNDF for stability and noise filtering. |
Key Features
| Feature | Design Value |
|---|---|
| Force-sense output architecture | Separates OUTF (power delivery) and OUTS (feedback sensing) to eliminate PCB trace IR-drop errors in remote loads. |
| A-grade temperature stability | 6ppm/°C max drift ensures <±0.075% output variation across –40°C to +125°C, critical for uncalibrated field instruments. |
| Ultra-low 1/f noise | 4.8µVP-P (0.1–10Hz) enables sub-16-bit noise floor in DC-coupled sensor signal chains without post-filtering. |
| Enable-controlled power gating | Reduces supply current from 150µA to 6µA, extending battery life >20× in portable test equipment. |
| Capacitive-load stability | Stable with 0.1–10µF output capacitance, accommodating ceramic, tantalum, or polymer caps for EMI robustness. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR4550BRZ | 5.0V, 3ppm/°C max drift, 1.5µVP-P noise, SOIC-8 package, 950µA supply current | Lower drift/noise but 6× higher power; requires larger PCB area and heatsinking | Select when ultimate precision outweighs power/size constraints (e.g., lab-grade calibrators) |
| REF5050AIDR | 5.0V, 3ppm/°C max drift, 5.5µVP-P noise, SOIC-8, 1mA supply current | Similar noise, lower drift, but no enable pin and higher quiescent current | Choose for fixed-on applications needing tighter drift spec without shutdown capability |
Compared with ADR4550BRZ and REF5050AIDR, the MAX6071AAUT50+T trades 3ppm/°C drift for 150µA operation and SOT23 footprint-making it optimal for space-constrained, battery-aware industrial sensors where 6ppm/°C meets system-level accuracy budgets.

FAQ
What is the maximum input voltage for MAX6071AAUT50+T?
The MAX6071AAUT50+T specifies an absolute maximum input voltage of +6V, but its operational supply range is 5.2V to 5.5V for guaranteed 5.0V output accuracy and 60–150mV dropout performance. Exceeding 5.5V may degrade long-term stability or increase quiescent current beyond 235µA.
Does MAX6071AAUT50+T require an external filter capacitor like the MAX6070?
No, the MAX6071AAUT50+T does not include a FILTER pin and is not designed for external high-frequency noise filtering. Its internal architecture optimizes noise performance without external capacitors, unlike the MAX6070 which requires a 0.1µF capacitor on the FILTER pin for wideband noise reduction.
Can MAX6071AAUT50+T drive a 100Ω load?
No-MAX6071AAUT50+T is rated for ±10mA output current, limiting its minimum resistive load to 500Ω at 5.0V (V/I = 5V/10mA). Driving a 100Ω load would demand 50mA, exceeding its safe operating area and causing output droop or thermal shutdown.
Is MAX6071AAUT50+T qualified for automotive applications?
Yes, the MAX6071AAUT50+T is AEC-Q100 qualified for automotive use, supporting operation from –40°C to +125°C and meeting stress-test requirements for temperature cycling, humidity, and mechanical shock-making it suitable for battery monitoring, engine control, and ADAS subsystems.
How does the force-sense (OUTF/OUTS) configuration improve accuracy in MAX6071AAUT50+T?
The force-sense topology in MAX6071AAUT50+T separates OUTF (high-current output path) from OUTS (low-current sense feedback), allowing OUTS to connect directly to the load ground. This eliminates voltage drop errors caused by PCB trace resistance between the IC and load, maintaining <0.01% gain accuracy even with 100mΩ interconnects.
