Product details
Overview
MAX6071BAUT50+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 (0.1Hz–10Hz) noise - enabling high-resolution ADC/DAC biasing and automotive sensor signal conditioning.
For engineers reviewing the MAX6071BAUT50+T datasheet, MAX6071BAUT50+T pinout, MAX6071BAUT50+T application, or MAX6071BAUT50+T equivalent, this page provides verified electrical specs, thermal performance over –40°C to +125°C, enable-controlled shutdown, and design-critical output stability under 10mA load sourcing/sinking.
Technical Context
The MAX6071BAUT50+T implements a bandgap-based series reference architecture with force-sense output topology (OUTF/OUTS pins), supporting Kelvin sensing for load regulation accuracy. It features an integrated enable input (EN) with logic-level thresholds (VIH = 0.7×VIN, VIL = 0.3×VIN) and operates from 5.2V to 5.5V supply.
Unlike the filter-capable MAX6070 variant, the MAX6071BAUT50+T omits the FILTER pin and uses separate GNDF/GNDS grounds to minimize ground-bounce-induced error - critical for sub-16-bit measurement systems requiring <10ppm total error budget.
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) - contributes ≤±0.75mV error across –40°C to +125°C ambient range. |
| Noise (0.1–10Hz) | 4.8µVP-P - enables <18-bit effective resolution in precision data acquisition systems. |
| Supply Current | 150µA typical - supports low-power battery-operated instrumentation with minimal quiescent burden. |
| Load Current | ±10mA sourcing/sinking - drives 500Ω loads directly, eliminating external buffers in most sensor front-ends. |
| Dropout Voltage | 60–150mV at 10mA - allows operation with only 5.15V input when VOUT = 5.0V, easing LDO selection. |
| Ripple Rejection | 74dB at 60Hz - suppresses line-frequency coupling in industrial power-supply monitoring circuits. |
Pinout & Package
Package: 6-pin SOT23 (U6+5A), 2.9mm × 1.6mm footprint, JEDEC MS-012 compliant, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GNDF | Ground Force | Reference ground return path for internal bandgap circuitry; must be tied to clean system ground near IC body. |
| 2 - GNDS | Ground Sense | Sense ground connection at remote load point; separates reference ground from high-current return paths. |
| 3 - EN | Enable Control | Active-high digital input (VIH ≥ 0.7×VIN); asserts internal reference on rising edge with 75µs settling to 0.01%. |
| 4 - IN | Supply Input | Input voltage range 5.2V–5.5V; requires local 0.1µF ceramic bypass capacitor to GNDF. |
| 5 - OUTS | Reference Sense Output | High-impedance sense node connected to load ground; used with OUTF for 4-wire Kelvin regulation. |
| 6 - OUTF | Reference Force Output | Low-impedance output driving load; shorted to OUTS near load to cancel trace resistance error. |
Key Features
| Feature | Design Value |
|---|---|
| Force-sense output topology | Eliminates voltage drop error from PCB trace resistance up to 100mΩ between IC and load. |
| AEC-Q100 qualified | Validated for automotive applications including engine control modules and ADAS sensor interfaces. |

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, 1.8µVP-P noise, SOIC-8 package, no enable pin | Lacks shutdown control; larger footprint; superior noise but higher cost and power (950µA) | Select when ultra-low noise dominates over power and size constraints. |
| REF5050AIDR | 5.0V, 3ppm/°C max drift, 5.5µVP-P noise, SOIC-8, enable pin, 1.2mA supply current | Higher quiescent current; same force-sense capability; wider VIN range (4.5–18V) | Select when wide input voltage range and legacy SOIC compatibility are required. |

FAQ
What is the maximum input voltage for the MAX6071BAUT50+T?
The MAX6071BAUT50+T specifies a guaranteed operating input voltage range of 5.2V to 5.5V for its 5.0V output version. Absolute maximum rating is +6V on the IN pin relative to GNDF/GNDS. Exceeding 5.5V may degrade long-term stability or increase dropout-related error; operation above 5.5V is not characterized or recommended.
Does the MAX6071BAUT50+T support force-sense (Kelvin) connections?
Yes, the MAX6071BAUT50+T supports true 4-wire Kelvin sensing via dedicated OUTF (force) and OUTS (sense) pins. This configuration cancels voltage drop across PCB traces or connectors, maintaining output accuracy even with 100mΩ series resistance - essential for high-precision load regulation in metrology-grade systems.
What is the enable settling time for the MAX6071BAUT50+T?
The MAX6071BAUT50+T requires 75µs to settle to 0.01% of final 5.0V output after EN transitions high, measured with COUT = 0.1µF. This fast wake-up enables duty-cycled operation in portable instruments, reducing average power while preserving measurement integrity during active sampling windows.
Is the MAX6071BAUT50+T qualified for automotive use?
Yes, the MAX6071BAUT50+T is AEC-Q100 qualified (Grade 1: –40°C to +125°C), with full parametric validation across temperature, lifetime reliability testing, and failure mode analysis per automotive standards - making it suitable for engine control, transmission, and ADAS subsystems.
How does the noise performance of the MAX6071BAUT50+T compare to the MAX6070?
The MAX6071BAUT50+T delivers 4.8µVP-P (0.1–10Hz) and 6µVRMS (10Hz–10kHz) noise at 5.0V output. The MAX6070 variant achieves lower broadband noise (e.g., 3µVRMS) when its external FILTER pin is used with a 0.1µF capacitor - but the MAX6071BAUT50+T trades that capability for simplified layout and reduced BOM count in fixed-noise-tolerance applications.
