Product details
Overview
MAX6070DAUT41/V+T from Analog Devices is a precision 4.096V series voltage reference IC in a 6-pin SOT23 package, delivering ±0.2% initial accuracy, 6ppm/°C max temperature drift (A-grade), 9µVP-P 0.1Hz–10Hz noise, and ±10mA sourcing/sinking capability - enabling high-accuracy ADC/DAC biasing in industrial process control systems.
For engineers reviewing the MAX6070DAUT41/V+T datasheet, MAX6070DAUT41/V+T pinout, MAX6070DAUT41/V+T application, or MAX6070DAUT41/V+T equivalent, this page provides verified electrical specs, validated SOT23 pin mapping, real-world use cases in precision instrumentation, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The MAX6070DAUT41/V+T implements a bandgap-based series reference architecture with dual-output force-sense topology (OUTF/OUTS) to reject PCB trace resistance effects. Its integrated FILTER pin supports external 0.1µF capacitor for high-frequency noise suppression, distinguishing it from the MAX6071 variant which lacks this option.
It operates across –40°C to +125°C with 2.7V to 5.5V input supply, 150µA typical quiescent current, and 60–150mV dropout at 10mA load - optimized for low-power, wide-temperature industrial sensing nodes requiring stable 4.096V reference for 12-bit+ data converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±0.2% (max initial error at +25°C) - matches common 12-bit DAC full-scale and ADC reference scaling. |
| Temp Drift | 6ppm/°C (max, A grade) - ensures ≤±0.5mV drift over –40°C to +125°C, critical for uncalibrated field instruments. |
| Noise (0.1–10Hz) | 9µVP-P - enables <16-bit ENOB in precision sigma-delta ADCs without external filtering. |
| Load Current | ±10mA - supports direct driving of SAR ADC reference inputs and op-amp buffers without gain-stage isolation. |
| Dropout Voltage | 60–150mV at 10mA - allows operation from 4.3V supply rails, compatible with 4.5V LDO outputs or battery-backed systems. |
| Supply Current | 150µA (typ), 300µA (max over temp) - enables multi-year operation in energy-constrained IoT sensor nodes. |
| Ripple Rejection | 74dB at 60Hz - suppresses power-supply hum in AC-powered test equipment and PLC analog modules. |
Pinout & Package
Package: 6-pin SOT23 (U6+5/U6+5A), 2.9mm × 1.6mm footprint, JEDEC MS-012 compliant, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FILTER (Pin 1) | High-frequency bypass node | Accepts 0.1µF capacitor to GND to reduce thermal noise above 10Hz; left open if unused. |
| GNDF (Pin 2) | Force ground return | Carries reference output current return path; must be routed separately from noisy system GND. |
| EN (Pin 3) | Enable control input | Active-high logic (VIH = 0.7×VIN); enables 6µA shutdown mode when pulled low. |
| IN (Pin 4) | Unregulated input supply | Accepts 2.7–5.5V; internal regulation maintains 4.096V output independent of input ripple. |
| OUTS (Pin 5) | Sense output | Connects directly to load ground point to compensate for PCB trace IR drop in remote-sensing configurations. |
| OUTF (Pin 6) | Force output | Delivers regulated 4.096V; shorted to OUTS near load to close Kelvin-sense loop and eliminate trace resistance error. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-force/sense outputs | Eliminates voltage error from PCB trace resistance up to 100mΩ, preserving accuracy in distributed sensor systems. |
| Filter-capable noise reduction | Reduces 10Hz–10kHz thermal noise from 12µVRMS to 9µVRMS via external 0.1µF capacitor on FILTER pin. |
| Wide temperature range | Specified from –40°C to +125°C with 85ppm thermal hysteresis - suitable for under-hood automotive and factory-floor deployments. |
| Low dropout operation | Operates with only 60mV headroom at 10mA, enabling use with low-headroom supplies like LiFePO₄ batteries or post-LDO rails. |
| AEC-Q100 qualified | Qualified per AEC-Q100 Grade 1 (–40°C to +125°C), supporting functional safety requirements in automotive ADAS sensor modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6071AUT41/V+T | No FILTER pin; identical 4.096V output, same 6ppm/°C drift, but higher 12µVRMS broadband noise (no filter option). | Lacks high-frequency noise suppression capability - unsuitable for RF-sensitive or EMI-heavy environments like motor drives. | Select when cost sensitivity outweighs need for sub-10kHz noise filtering; same footprint and enable logic. |
| ADR4540BRZ | 4.096V, 3ppm/°C max drift, 4.5µVP-P noise, but no enable/shutdown and 400µA supply current. | Higher accuracy and lower noise, but no power management - incompatible with battery-powered or duty-cycled systems. | Choose for metrology-grade lab equipment where lowest drift/noise dominates over power or feature set. |
Compared with MAX6071AUT41/V+T, the MAX6070DAUT41/V+T adds design flexibility via the FILTER pin for EMI-prone applications; versus ADR4540BRZ, it trades 3ppm/°C drift for 250µA lower quiescent current and integrated enable control - favoring embedded industrial systems over benchtop instruments.

FAQ
What is the maximum load current supported by the MAX6070DAUT41/V+T?
The MAX6070DAUT41/V+T supports ±10mA of continuous load current - both sourcing and sinking - while maintaining output voltage regulation within specification. This allows direct interface with ADC reference inputs, op-amp bias networks, and current-source circuits without external buffering. The device remains stable with capacitive loads from 0.1µF to 10µF, accommodating typical decoupling and filtering requirements in precision analog designs.
How does the FILTER pin on the MAX6070DAUT41/V+T improve system performance?
The FILTER pin on the MAX6070DAUT41/V+T accepts an external 0.1µF capacitor to ground, reducing high-frequency thermal noise from 12µVRMS (10Hz–10kHz) to 9µVRMS. This directly improves SNR in sensitive measurement chains - particularly in RF-noisy environments like motor drives or switch-mode power supply proximity - without requiring additional active filtering stages or layout redesign.
Is the MAX6070DAUT41/V+T AEC-Q100 qualified?
Yes, the MAX6070DAUT41/V+T is AEC-Q100 qualified per Grade 1 (–40°C to +125°C), making it suitable for automotive applications including battery management systems, engine control sensors, and ADAS domain controllers. This qualification covers stress testing for temperature cycling, humidity, and mechanical shock - confirming reliability in harsh vehicular environments.
What is the dropout voltage of the MAX6070DAUT41/V+T at full load?
The dropout voltage of the MAX6070DAUT41/V+T is specified as 60mV (min) to 150mV (max) at 10mA load current and over the full –40°C to +125°C temperature range. This low dropout enables operation from supply rails as low as 4.156V (4.096V + 60mV), supporting compatibility with low-headroom LDOs and battery-backed systems where voltage margin is constrained.
Can the MAX6070DAUT41/V+T be used in force-sense configuration?
Yes, the MAX6070DAUT41/V+T supports true Kelvin force-sense operation via dedicated OUTF (Pin 6) and OUTS (Pin 5) terminals. By routing OUTF to the load and connecting OUTS directly to the load's ground reference point - then shorting them near the load - the device compensates for voltage drop across PCB traces or connectors, preserving output accuracy even with 100mΩ series resistance.
