Product details
Overview
MAX6070AAUT33/V+ from Analog Devices is a precision 3.3V series voltage reference IC in 6-pin SOT23 package, delivering ±0.04% initial accuracy, 6ppm/°C max temperature drift (A grade), and ultra-low 9.6µVP-P 1/f noise (0.1Hz–10Hz) at 3.3V output. It sources/sinks ±10mA, operates from 4.3V to 5.5V input, and supports high-accuracy industrial data acquisition systems requiring stable excitation for 16-bit+ ADCs.
For engineers reviewing the MAX6070AAUT33/V+ datasheet, MAX6070AAUT33/V+ pinout, MAX6070AAUT33/V+ application, or MAX6070AAUT33/V+ equivalent, key selection criteria include its integrated noise-filter option (FILTER pin), 75–150mV dropout at 10mA, 80dB ripple rejection at 60Hz, and AEC-Q100 qualification for automotive sensor signal conditioning.
Technical Context
The MAX6070AAUT33/V+ implements a bandgap-based series voltage reference architecture with force-sense (OUTF/OUTS) outputs and dedicated filter input (FILTER) to suppress high-frequency noise. Its dual-ground structure (GNDF/GNDS) separates force and sense return paths, enabling Kelvin sensing for load regulation down to 125µV/mA (sink) and 135µV/mA (source).
It features active enable control (EN), shutdown current of ≤6µA, and operates across –40°C to +125°C. The device requires external 0.1µF capacitor on FILTER for noise reduction and supports capacitive loads from 0.1µF to 10µF while maintaining stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.300V ±0.04% at +25°C - enables direct interface with 3.3V logic and ADC reference inputs without scaling. |
| Temp Drift (max) | 6ppm/°C (A grade) - ensures ≤±0.0025V output variation over –40°C to +125°C for <0.1% system error budget. |
| 1/f Noise | 9.6µVP-P (0.1Hz–10Hz) - critical for low-frequency precision measurements in weigh scales and strain gauge bridges. |
| Dropout Voltage | 75–150mV at 10mA - allows operation with minimal headroom from 3.3V supply rails or battery-powered systems. |
| Ripple Rejection | 80dB at 60Hz - suppresses power supply coupling in noisy industrial environments with AC/DC converters. |
| Supply Current | 150–235µA (typ/max at +25°C) - enables ultra-low-power operation in always-on sensor nodes and portable instrumentation. |
| Enable Logic | VIH = 0.7×VIN, VIL = 0.3×VIN - compatible with standard CMOS microcontrollers for dynamic power gating. |
Pinout & Package
Package: 6-pin SOT23 (U6+5/U6+5A), 2.9mm × 1.6mm × 1.1mm, RoHS-compliant, thermal resistance θJA = 230°C/W (multi-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - FILTER | Noise filter input | Accepts 0.1µF bypass capacitor to ground; enables high-frequency noise suppression when used (not required for basic operation). |
| 2 - GNDF | Ground Force | Return path for internal reference core; must be connected to clean system ground near IC body. |
| 3 - EN | Enable control | Active-high digital input; drives device into 6µA shutdown mode when low; compatible with 1.8V–5.5V logic. |
| 4 - IN | Supply input | Input voltage range 4.3V–5.5V; minimum headroom defined by dropout spec (75mV @ 10mA). |
| 5 - OUTS | Voltage sense output | Kelvin sense connection to load ground; minimizes errors from PCB trace resistance in precision applications. |
| 6 - OUTF | Voltage force output | Main reference output; must be shorted to OUTS near load; bypassed with 0.1–10µF capacitor to GNDF. |

FAQ
What is the maximum load current supported by the MAX6070AAUT33/V+?
The MAX6070AAUT33/V+ can source and sink up to ±10mA of load current while maintaining specified accuracy and regulation. At 10mA sink, load regulation is 125µV/mA; at 10mA source, it is 135µV/mA. Exceeding ±10mA may cause output deviation beyond datasheet limits and increased thermal drift.
Does the MAX6070AAUT33/V+ require an external capacitor on the FILTER pin?
No-the FILTER pin on the MAX6070AAUT33/V+ is optional. A 0.1µF capacitor to ground improves high-frequency noise rejection (e.g., switching regulator ripple), but the device operates fully functional without it. When omitted, thermal noise dominates above 10Hz; when used, 10Hz–10kHz noise drops to 9µVRMS.
How does the force-sense (OUTF/OUTS) configuration improve accuracy in the MAX6070AAUT33/V+?
The MAX6070AAUT33/V+ uses separate force (OUTF) and sense (OUTS) outputs to eliminate voltage drop errors caused by PCB trace resistance and load current. By routing OUTS directly to the load's ground reference point, the internal amplifier regulates OUTF to maintain exact 3.300V at the load-even with up to 100mΩ trace resistance-ensuring <0.01% gain error in precision ADC/DAC circuits.
Is the MAX6070AAUT33/V+ qualified for automotive applications?
Yes-the MAX6070AAUT33/V+ is AEC-Q100 qualified (Grade 1: –40°C to +125°C), with full characterization across temperature, lifetime stability (35ppm over 1000 hours), and robust ESD tolerance. It is designed for automotive subsystems including engine control units, battery management sensors, and ADAS radar signal chains where reference stability directly impacts functional safety compliance.
What is the minimum input voltage required for the MAX6070AAUT33/V+ to regulate at 3.3V output?
The MAX6070AAUT33/V+ requires a minimum input voltage of 4.3V to guarantee regulation at 3.3V output across full temperature and load conditions. This is derived from its maximum dropout voltage of 150mV at 10mA and –40°C to +125°C, plus margin for line regulation. Below 4.3V, output accuracy degrades and may fall out of specification.
