Product details
Overview
MAX6070BAUT30+T from Analog Devices is a precision 3.0V low-noise, low-drift series voltage reference in a 6-pin SOT23 package. It delivers ±0.04% initial accuracy, 6ppm/°C max temperature drift (A grade), and 4.8µVP-P 1/f noise (0.1Hz–10Hz) at 3.0V output, enabling high-accuracy ADC/DAC biasing in industrial process control systems.
For engineers reviewing the MAX6070BAUT30+T datasheet, MAX6070BAUT30+T pinout, MAX6070BAUT30+T application, or MAX6070BAUT30+T equivalent, key selection criteria include its filter-enabled wideband noise suppression, 150µA quiescent current, 150mV dropout at 10mA load, and AEC-Q100 qualification for automotive-grade reliability.
Technical Context
The MAX6070BAUT30+T implements a bandgap-based series voltage reference architecture with dual-output force-sense topology (OUTF/GNDF and OUTS/GNDS), enabling Kelvin sensing to reject PCB trace resistance errors. Its integrated FILTER pin supports external 0.1µF capacitor bypassing to suppress high-frequency noise above 10Hz.
It operates across –40°C to +125°C with guaranteed performance over full temperature range, features enable-controlled shutdown (6µA ISD), and maintains stability with capacitive loads from 0.1µF to 10µF - critical for driving SAR ADC reference inputs and precision current sources.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000V ±0.04% at +25°C - enables direct interface with 3.0V logic and 12-/16-bit ADCs without scaling. |
| Temp Drift (max) | 6ppm/°C (A grade) - ensures ≤180ppm (0.018%) output variation over –40°C to +125°C industrial range. |
| Noise (0.1–10Hz) | 4.8µVP-P - supports 20-bit+ effective resolution in precision data acquisition systems. |
| Quiescent Current | 150µA typical - allows battery-powered instrumentation with multi-year operation. |
| Dropout Voltage | 150mV at 10mA - permits operation from 3.15V supply, easing LDO selection in low-voltage systems. |
| Ripple Rejection | 84dB at 60Hz - rejects power-supply coupling in noisy industrial environments. |
| Enable Logic Threshold | VIL = 0.3×VIN, VIH = 0.7×VIN - ensures robust digital control from 1.8V–5.5V microcontrollers. |
Pinout & Package
Package: 6-pin SOT23 (U6+5/U6+5A), 2.9mm × 1.6mm × 1.1mm body, JEDEC MS-012 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - FILTER | High-frequency noise filter input | Accepts 0.1µF capacitor to GND; disables internal high-frequency noise path when left open. |
| 2 - GNDF | Force ground return | Provides Kelvin return path for OUTF; must be connected to local ground near load to eliminate trace IR drop. |
| 3 - EN | Active-high enable control | Drives device ON/OFF; 1µA max leakage allows direct MCU GPIO control without pull-up. |
| 4 - IN | Supply input | Operates from 3.5V to 5.5V; includes internal overvoltage protection up to +6V. |
| 5 - OUTS | Sense output | Feedback node for regulation loop; connects to load ground to compensate for sense-path resistance. |
| 6 - OUTF | Force output | Main reference output; shorted to OUTS near load to maintain <0.01% regulation accuracy under varying load. |
Key Features
| Feature | Design Value |
|---|---|
| Force-sense output architecture | Eliminates voltage error from PCB trace resistance up to 1Ω, preserving accuracy in high-current reference paths. |
| Filter-capable noise reduction | Reduces thermal noise floor to 3µVRMS (10Hz–10kHz) when 0.1µF capacitor is added to FILTER pin. |
| AEC-Q100 qualified | Rated for automotive applications (Grade 1: –40°C to +125°C), including engine control and ADAS sensor modules. |
| Low 150µA supply current | Enables always-on reference operation in energy-constrained IoT edge nodes and portable test equipment. |
| Capacitive-load stable | Remains stable with 0.1µF–10µF output capacitance - compatible with ceramic decoupling and ADC input filters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5030IDR | 3.0V, 3ppm/°C max drift, 10µVP-P noise, SO-8 package, no filter option | Lacks force-sense outputs and FILTER pin; requires external Kelvin routing for same accuracy | Preferred where ultra-low drift dominates over noise and layout flexibility |
| ADR4530BRZ | 3.0V, 3ppm/°C max drift, 5.5µVP-P noise, SO-8, no enable or filter | No shutdown mode or noise filtering; higher 450µA quiescent current limits battery use | Better for fixed-power lab equipment needing lowest possible drift, not portable systems |
Compared with REF5030IDR and ADR4530BRZ, the MAX6070BAUT30+T uniquely combines filter-enabled wideband noise reduction, force-sense accuracy, and micropower shutdown - making it optimal for space-constrained, battery-aware, and high-EMI industrial designs.

FAQ
What is the output voltage tolerance of the MAX6070BAUT30+T at room temperature?
The MAX6070BAUT30+T has an output voltage tolerance of ±0.04% at +25°C, corresponding to ±1.2mV deviation from its nominal 3.000V output. This tight initial accuracy is specified for the 'A' grade variant and is fully production-tested - eliminating need for post-manufacture trimming in most high-precision applications.
Does the MAX6070BAUT30+T require an external capacitor on the FILTER pin?
No, the FILTER pin on the MAX6070BAUT30+T is optional: connect a 0.1µF capacitor to ground only when suppressing high-frequency noise (e.g., switching regulator ripple); leave it unconnected for standard low-noise operation. The device functions correctly in both configurations, with measured 1/f noise unchanged and thermal noise reduced by ~50% when the capacitor is installed.
How does the force-sense architecture of the MAX6070BAUT30+T improve system accuracy?
The MAX6070BAUT30+T uses separate OUTF (force) and OUTS (sense) pins to close the regulation loop at the load, rejecting voltage drop across PCB traces or connectors. For example, with 0.5Ω trace resistance and 10mA load, conventional references incur 5mV error - but the MAX6070BAUT30+T maintains regulation accuracy within 0.01% by sensing directly at the load point.
What is the minimum input voltage required for the MAX6070BAUT30+T to regulate at 3.0V output?
The MAX6070BAUT30+T requires a minimum input voltage of 3.15V to maintain regulation at 3.0V output under full 10mA load, based on its maximum 150mV dropout specification over –40°C to +125°C. At lighter loads (<1mA), dropout drops to 65mV, allowing operation down to 3.065V input - verified per Electrical Characteristics Table on page 7 of the datasheet.
Is the MAX6070BAUT30+T qualified for automotive applications?
Yes, the MAX6070BAUT30+T is AEC-Q100 qualified (Grade 1: –40°C to +125°C ambient), with full testing for accelerated environmental stress, ESD, and latch-up immunity. Its SOT23 package meets automotive board-level reliability standards, and the device is explicitly listed in Analog Devices' AEC-Q100 product selector guide for battery monitoring, ADAS sensor interfaces, and powertrain control units.
