Product details
Overview
MAX6070AAUT50/V+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-accuracy ADC/DAC biasing in industrial process control systems.
For engineers reviewing the MAX6070AAUT50/V+T datasheet, MAX6070AAUT50/V+T pinout, MAX6070AAUT50/V+T application, or MAX6070AAUT50/V+T equivalent, key selection criteria include its filter-enabled wideband noise suppression, 10mA bidirectional load drive, 2.7V to 5.5V input range, and AEC-Q100 qualification for automotive-grade reliability.
Technical Context
The MAX6070AAUT50/V+T implements a bandgap-based series 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 150µA typical supply current and features enable-controlled shutdown (6µA ISD), 10mA sourcing/sinking capability, and 80dB ripple rejection at 60Hz-optimized for low-drift, low-noise analog signal chains in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±0.04% at +25°C - ensures direct compatibility with 5V ADC full-scale ranges without calibration. |
| Temp Drift (max) | 6ppm/°C (A grade) - limits output error to ≤±750µV over –40°C to +125°C, critical for uncalibrated industrial sensors. |
| 1/f Noise | 4.8µVP-P (0.1Hz–10Hz) - enables 20-bit+ effective resolution in precision data acquisition systems. |
| Supply Current | 150µA typical - allows battery-powered instrumentation with multi-year runtime on coin cells. |
| Load Drive | ±10mA - supports direct driving of SAR ADC reference inputs and precision current sources without buffers. |
| Dropout Voltage | 150mV max at 10mA - permits operation from 5.15V rails, easing LDO selection in 5V systems. |
| Ripple Rejection | 80dB at 60Hz - rejects power-supply hum in AC-powered test equipment and PLC modules. |
Pinout & Package
Package: 6-pin SOT23 (package code U6+5A), 2.9mm × 1.6mm footprint, JEDEC MS-012 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - FILTER | High-frequency noise filter input | Accepts 0.1µF capacitor to ground; enables >10kHz noise attenuation without affecting DC accuracy. |
| 2 - GNDF | Force ground return | Carries reference output current return path; must be routed separately from GNDS to avoid IR drop errors. |
| 3 - EN | Enable control input | Logic-high (>0.7×VIN) activates reference; logic-low (<0.3×VIN) reduces quiescent current to 6µA. |
| 4 - IN | Positive supply input | Accepts 2.7V–5.5V; internal regulation maintains stable 5.0V output independent of input ripple. |
| 5 - OUTS | Sense output | Provides feedback to internal amplifier; connects directly to load ground to compensate trace resistance. |
| 6 - OUTF | Force output | Delivers regulated 5.0V; must be shorted to OUTS near the load to close Kelvin loop and ensure accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| 6-pin SOT23 package | Reduces board area by >50% vs. SO-8 references while maintaining thermal performance (θJA = 230°C/W). |

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, SO-8 package, no enable or filter pin | Lacks shutdown and noise filtering; requires larger PCB area; better drift but higher cost | Preferred when ultimate drift performance is prioritized over size, power, and noise flexibility |
| REF5050AIDR | 5.0V, 3ppm/°C max drift, 4.5µVP-P noise, SO-8, no enable, no filter, 10mA drive | No enable/shutdown; no FILTER pin; same force-sense architecture but larger package | Chosen for legacy SO-8 layouts where space is not constrained and lowest possible drift is required |
Compared with ADR4550BRZ and REF5050AIDR, the MAX6070AAUT50/V+T trades minor drift penalty (6ppm vs. 3ppm) for critical system-level advantages: 6-pin SOT23 footprint, integrated enable for power cycling, and configurable high-frequency noise filtering-making it optimal for space-constrained, battery-aware, and wideband-sensitive designs.

FAQ
What is the output voltage tolerance of the MAX6070AAUT50/V+T at room temperature?
The MAX6070AAUT50/V+T has an output voltage accuracy of ±0.04% at +25°C, meaning its 5.000V nominal output falls within 4.998V to 5.002V under standard test conditions. This tight tolerance eliminates need for post-production trimming in most high-precision applications and is guaranteed for the A-grade variant specified in the part number.
How does the FILTER pin on the MAX6070AAUT50/V+T improve system performance?
The FILTER pin on the MAX6070AAUT50/V+T accepts an external 0.1µF capacitor to ground, reducing thermal noise density to 30nV/√Hz at 1kHz and lowering wideband RMS noise to 5.0µVRMS (10Hz–10kHz). This directly enhances effective resolution in fast-sampling ADCs and mitigates switching noise coupling in mixed-signal PCBs.
Can the MAX6070AAUT50/V+T operate from a 3.3V supply rail?
No-the MAX6070AAUT50/V+T requires a minimum supply voltage of 2.7V, but its 5.0V output necessitates a headroom of at least 150mV dropout. With 5.0V output, the absolute minimum input is 5.15V; therefore, it cannot operate from a 3.3V rail. It is designed for 5.5V or 5.0V systems with appropriate pre-regulation.
What is the purpose of the separate GNDF and GNDS pins on the MAX6070AAUT50/V+T?
The MAX6070AAUT50/V+T uses separate GNDF (force ground) and GNDS (sense ground) pins to implement a Kelvin-connected reference output. GNDF carries load current return, while GNDS provides feedback to the internal amplifier. Routing them independently eliminates voltage error caused by PCB trace resistance, preserving the ±0.04% accuracy at the load point.
Is the MAX6070AAUT50/V+T qualified for automotive applications?
Yes-the MAX6070AAUT50/V+T is AEC-Q100 qualified for Grade 1 (–40°C to +125°C), making it suitable for automotive applications including battery monitoring systems, engine control sensor interfaces, and ADAS power domain references where extended temperature operation and reliability are mandatory.
