Product details
Overview
MAX6070DAUT30/V+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 2.5V - scaled to 10µVP-P at 3.0V per datasheet - enabling high-accuracy ADC/DAC biasing in industrial process control systems.
For engineers reviewing the MAX6070DAUT30/V+T datasheet, MAX6070DAUT30/V+T pinout, MAX6070DAUT30/V+T application, or MAX6070DAUT30/V+T equivalent, this device supports wideband noise filtering via dedicated FILTER pin, operates from 3.5V to 5.5V input, sinks/sources ±10mA, and maintains stability with 0.1–10µF capacitive loads - critical for precision sensor signal chains and automotive-grade instrumentation.
Technical Context
The MAX6070DAUT30/V+T implements a bandgap-based series voltage reference architecture with force-sense output topology (OUTF/OUTS) and integrated enable/shutdown control. Its dual-ground structure (GNDF/GNDS) separates force and sense paths to minimize PCB trace resistance errors, while the FILTER pin accepts an external 0.1µF capacitor to suppress high-frequency noise beyond 10kHz.
This variant is the A-grade, 3.0V output version of the MAX6070 family, specified over –40°C to +125°C, with 150µA typical supply current, 65–150mV dropout (at 10mA), and 78dB ripple rejection at 60Hz - optimized for low-power, high-stability applications where long-term drift (<40ppm over 1000 hours) and thermal hysteresis (85ppm) are tightly controlled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000V ±0.04% at +25°C - ensures direct compatibility with 3.0V ADC reference inputs without calibration. |
| Temp Drift (max) | 6ppm/°C (A grade) - limits output variation to ±0.72mV over –40°C to +125°C ambient range. |
| 1/f Noise (0.1–10Hz) | 10µVP-P - measured per Electrical Characteristics table for MAX607__AUT30, directly impacts 24-bit ADC effective resolution. |
| Supply Current | 160µA typical at +25°C - enables battery-powered instrumentation with >1-year runtime on coin cell. |
| Load Current | ±10mA sourcing/sinking - supports driving 10kΩ DAC reference inputs or 100Ω precision current sources. |
| Dropout Voltage | 65mV min at 10mA - allows operation from 3.065V supply, compatible with LDOs delivering 3.3V ±3%. |
| Ripple Rejection | 78dB at 60Hz - attenuates power-supply hum to <12µV residual on 3.0V output. |
Pinout & Package
Package: 6-pin SOT23 (package code U6+5A), 2.9mm × 1.6mm footprint, JEDEC MO-178AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - FILTER | High-frequency bypass input | Accepts 0.1µF capacitor to GND; enables 10Hz–10kHz noise reduction without affecting DC accuracy. |
| 2 - GNDF | Force ground reference | Return path for internal reference core; must be connected to clean system ground near IN pin. |
| 3 - EN | Enable control input | Logic-high (>0.7×VIN) activates output; logic-low (<0.3×VIN) reduces supply current to ≤6µA. |
| 4 - IN | Positive supply input | Operates from 3.5V to 5.5V; requires local 0.1µF decoupling to GNDF. |
| 5 - OUTS | Sense output terminal | Connects to load ground point; closes feedback loop to reject trace IR drop errors. |
| 6 - OUTF | Force output terminal | Delivers regulated 3.0V; bypass with 0.1–10µF capacitor to GNDF for stability and noise filtering. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6071AUT30/V+T | No FILTER pin; single-output (OUT) instead of force-sense (OUTF/OUTS); same 3.0V output, 6ppm/°C drift, but 9µVP-P 1/f noise. | Lacks high-frequency noise filtering capability and trace-resistance compensation - suitable only for non-critical, low-impedance loads. | Select when board space is constrained and noise/trace resistance are not design-limiting factors. |
| ADR4530BRZ | 3.0V, 3ppm/°C max drift, 3.5µVP-P noise, SOIC-8 package; no enable or filter pins; higher 850µA supply current. | Higher accuracy and lower noise, but larger footprint and no shutdown mode - incompatible with ultra-low-power or space-constrained designs. | Choose for metrology-grade accuracy where power and size are secondary to long-term stability. |
Compared with MAX6071AUT30/V+T, the MAX6070DAUT30/V+T provides superior noise filtering and force-sense accuracy at identical drift; versus ADR4530BRZ, it trades absolute precision for 5.3× lower supply current and integrated enable control in half the footprint.

FAQ
What is the output voltage tolerance of the MAX6070DAUT30/V+T at room temperature?
The MAX6070DAUT30/V+T has an output voltage tolerance of ±0.04% at +25°C, corresponding to ±1.2mV around its nominal 3.000V output. This specification is guaranteed for the A-grade variant and is fully tested in production, ensuring consistent performance across units without post-manufacturing calibration.
Does the MAX6070DAUT30/V+T require external capacitors, and if so, what values are recommended?
Yes - the MAX6070DAUT30/V+T requires three external capacitors: a 0.1µF ceramic capacitor from IN to GNDF, a 0.1µF capacitor from FILTER to GND (if noise filtering is used), and a 0.1–10µF capacitor from OUTF to GNDF. These values are validated in the datasheet for stability, noise reduction, and transient response across the full operating temperature range.
How does the force-sense (OUTF/OUTS) configuration improve accuracy in the MAX6070DAUT30/V+T?
The force-sense configuration in the MAX6070DAUT30/V+T separates the output drive path (OUTF) from the feedback sensing path (OUTS), allowing the device to regulate voltage precisely at the load point. This compensates for voltage drop across PCB traces or connectors - up to 100mΩ - eliminating a key source of system-level error in precision measurement circuits.
Can the MAX6070DAUT30/V+T operate from a 3.3V supply, and what is its minimum input voltage?
Yes - the MAX6070DAUT30/V+T operates from a minimum input voltage of 3.5V (per Electrical Characteristics for VOUT = 3.000V), so a nominal 3.3V supply is insufficient. The required headroom is defined by dropout voltage: at 10mA load, dropout is 65–150mV, meaning VIN must be ≥3.065V, but the absolute minimum specified VIN is 3.5V to guarantee all parameters across temperature.
Is the MAX6070DAUT30/V+T AEC-Q100 qualified, and which grade does it meet?
Yes - the MAX6070DAUT30/V+T is AEC-Q100 qualified per the manufacturer's ordering information, meeting Grade 1 requirements (–40°C to +125°C operating temperature). This qualification covers stress testing for automotive reliability, including temperature cycling, humidity bias, and ESD robustness - making it suitable for battery monitoring and ADAS subsystems.
