Product details
Overview
MAX6070AAUT33+T from Analog Devices is a precision 3.3V series voltage reference IC with ultra-low 1/f noise (9.6µVP-P, 0.1Hz–10Hz), 6ppm/°C max temperature drift (A grade), and ±0.04% initial accuracy. It operates from 4.3V to 5.5V input, delivers ±10mA load current, and features integrated noise filtering for wideband instrumentation applications.
For engineers reviewing the MAX6070AAUT33+T datasheet, MAX6070AAUT33+T pinout, MAX6070AAUT33+T application, or MAX6070AAUT33+T equivalent, this device supports high-resolution ADC/DAC biasing, precision current sourcing, and automotive-grade sensor signal conditioning where low thermal hysteresis (85ppm) and long-term stability (35ppm/1000h) are critical.
Technical Context
The MAX6070AAUT33+T implements a bandgap-based series reference architecture with separate force (OUTF) and sense (OUTS) outputs enabling Kelvin sensing for improved load regulation. Its dedicated FILTER pin accepts an external 0.1µF capacitor to suppress high-frequency noise without affecting DC accuracy.
It integrates enable control (EN) with logic-level compatible thresholds (VIH = 0.7×VIN, VIL = 0.3×VIN), shutdown current of ≤6µA, and operates across –40°C to +125°C. The device achieves 80dB ripple rejection at 60Hz and maintains stability with capacitive loads from 0.1µF to 10µF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.300V ±0.04% at +25°C - enables direct interface with 3.3V ADC references and digital logic supply rails |
| Temp Drift (max) | 6ppm/°C (A grade) - ensures <±0.0008V output variation over –40°C to +125°C industrial range |
| 1/f Noise | 9.6µVP-P (0.1Hz–10Hz) - minimizes low-frequency error in precision weigh scales and strain gauge bridges |
| Supply Current | 150µA typical - supports battery-powered portable instrumentation with multi-year runtime |
| Dropout Voltage | 75mV min at 10mA load - allows operation with only 3.375V input, easing LDO selection in tight supply margins |
| Ripple Rejection | 80dB at 60Hz - rejects power-supply hum in industrial PLC analog input modules |
| Enable Settling | 10ms to 0.01% with 0.1µF filter cap - provides deterministic wake-up timing for power-gated systems |
Pinout & Package
MAX6070AAUT33+T uses a 6-pin SOT23 package (package code U6+5A, outline 21-0058), optimized for space-constrained PCB layouts in industrial sensors and automotive ECUs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FILTER | Noise filter input | Accepts 0.1µF bypass cap to ground; disables internal high-frequency noise path when left open |

| EN | Enable control | Active-high logic input; draws ≤1µA, supports microcontroller GPIO direct drive without level shifters |
| IN | Supply input | Accepts 4.3V–5.5V; includes internal overvoltage protection up to +6V |
| OUTS | Sense output | Connects to load ground point for remote sensing-eliminates IR drop error in long trace applications |
| OUTF | Force output | Delivers regulated 3.3V; must be shorted to OUTS near load to close Kelvin loop |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5033IDR | Higher initial accuracy (±0.02%), lower noise (4.5µVP-P), but no FILTER pin or Kelvin outputs | Lacks noise filtering and remote sensing-requires external RC network for EMI suppression | Select when ultimate DC accuracy outweighs need for integrated noise mitigation |
| ADR4533BRZ | Lower temp drift (3ppm/°C max), higher quiescent current (950µA), same SOT23-6 package | Not AEC-Q100 qualified; unsuitable for automotive under-hood deployment | Choose for lab-grade instrumentation where ultra-low drift justifies higher power and cost |
Compared with REF5033IDR and ADR4533BRZ, the MAX6070AAUT33+T uniquely combines Kelvin sensing, integrated noise filtering, and automotive qualification in a 150µA, 6-pin SOT23 package-making it optimal for space- and noise-constrained embedded systems requiring production-grade reliability.

FAQ
What is the maximum input voltage for MAX6070AAUT33+T?
The absolute maximum input voltage for MAX6070AAUT33+T is +6V, but its specified operating range is 4.3V to 5.5V for the 3.3V output variant. Exceeding 5.5V may degrade long-term stability or trigger internal protection circuits. Always maintain VIN ≥ VOUT + dropout (75mV min) to ensure regulation-so 3.375V is the practical minimum for 10mA loads. MAX6070AAUT33+T data confirms this across all electrical characteristics tables.
Does MAX6070AAUT33+T require an external capacitor on the FILTER pin?
No, the FILTER pin on MAX6070AAUT33+T is optional: connect a 0.1µF capacitor to ground only when suppressing high-frequency noise (e.g., in switch-mode power supply environments); leave it unconnected for pure low-noise DC applications. The device functions correctly without it, and the 9.6µVP-P 0.1Hz–10Hz noise spec applies regardless. MAX6070AAUT33+T's pin description explicitly states "Leave unconnected, if not used."
Can MAX6070AAUT33+T drive a 10µF output capacitor?
Yes, MAX6070AAUT33+T is stable with output capacitance from 0.1µF to 10µF per its datasheet, supporting both ceramic and tantalum types. This wide range accommodates bulk decoupling for noisy loads while preserving 0.01% settling in ≤10ms. However, larger capacitors increase turn-on time-e.g., 10µF extends settling beyond 10ms-so verify timing constraints in your specific application. MAX6070AAUT33+T's capacitive-load stability range is explicitly rated to 10µF.
Is MAX6070AAUT33+T pin-compatible with other MAX607x variants?
Yes, all MAX6070/MAX6071 devices-including MAX6070AAUT33+T-share identical 6-pin SOT23 pinouts and footprint (U6+5A), enabling voltage-output variants (1.25V–5.0V) to be swapped without PCB changes. Pin functions (FILTER, GNDF, EN, IN, OUTS, OUTF) and electrical tolerances are consistent across the family. MAX6070AAUT33+T's pin configuration diagram confirms full mechanical and functional compatibility within the series.
What is the thermal hysteresis specification for MAX6070AAUT33+T?
The thermal hysteresis for MAX6070AAUT33+T is 85ppm, defined as the change in +25°C output voltage before and after cycling between –40°C and +125°C. This value is guaranteed across all grades (A/B/D) and output voltages, ensuring repeatability in calibration-critical systems like portable test equipment. MAX6070AAUT33+T's Electrical Characteristics table on page 5 lists this parameter unconditionally for the 3.3V variant.
