Product details
Overview
MAX6070AAUT25+T from Analog Devices is a precision 2.5V series voltage reference IC with ultra-low 1/f noise (4.8µVP-P, 0.1Hz–10Hz), 6ppm/°C max temperature drift (A grade), and ±0.04% initial accuracy - designed for high-resolution ADC/DAC biasing, industrial process control, and automotive sensor signal conditioning.
For engineers reviewing the MAX6070AAUT25+T datasheet, MAX6070AAUT25+T pinout, MAX6070AAUT25+T application, or MAX6070AAUT25+T equivalent, key selection criteria include its dual-output force/sense architecture, integrated noise-filter option, 10mA sourcing/sinking capability, and AEC-Q100 qualification for automotive use.
Technical Context
The MAX6070AAUT25+T implements a bandgap-based series voltage reference with separate force (OUTF) and sense (OUTS) outputs to eliminate PCB trace resistance errors. Its internal filter pin enables external capacitor configuration (e.g., 0.1µF to ground) to suppress high-frequency noise above 10Hz.
It operates over –40°C to +125°C with 2.8V to 5.0V supply input, delivers stable 2.5V output under ±10mA load, and features enable-controlled shutdown (6µA ISD) and 80–150mV dropout at full load - supporting low-voltage, high-accuracy analog front-ends in space-constrained SOT23-6 layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500V ±0.04% at +25°C - ensures direct compatibility with 2.5V ADC reference inputs and eliminates calibration offset in precision measurement systems. |
| Temp Drift (max) | 6ppm/°C (A grade) - limits output variation to ±75ppm (±0.188mV) across –40°C to +125°C, critical for uncalibrated industrial sensors. |
| 1/f Noise | 4.8µVP-P (0.1Hz–10Hz) - enables sub-18-bit effective resolution in slow-sampling instrumentation without external filtering. |
| Supply Current | 150µA typical - supports battery-powered portable test equipment with multi-year operation on coin cells. |
| Load Current | ±10mA sourcing/sinking - drives 10kΩ loads directly and interfaces with op-amp buffers or SAR ADC reference inputs without gain-stage overhead. |
| Dropout Voltage | 110–230mV at 10mA - allows operation from 2.73V rails, enabling use with single-cell LiFePO₄ or regulated 3.3V supplies. |
| Ripple Rejection | 84dB at 60Hz - suppresses power-supply hum in AC-mains-powered PLC modules and motor-drive feedback circuits. |
Pinout & Package
Package: 6-pin SOT23 (U6+5/U6+5A), 2.9mm × 1.6mm footprint, RoHS-compliant, thermal resistance θJA = 230°C/W (multi-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FILTER | Noise filter input | Accepts external 0.1µF capacitor to GND; enables high-frequency noise suppression beyond 10Hz - essential for RF-sensitive applications like radar signal chains. |
| GNDF | Force ground | Provides dedicated return path for OUTF current; separates high-current reference output return from sensitive sense node to avoid ground bounce errors. |
| EN | Enable control | Active-high logic input (VIH = 0.7×VIN); enables fast 75µs turn-on settling - supports power-gating in energy-harvesting IoT nodes. |
| IN | Supply input | Accepts 2.8V–5.0V input; internal regulation maintains 2.5V output despite rail droop during microcontroller wake-up surges. |
| OUTS | Sense output | High-impedance feedback node connected to load ground; used with OUTF to compensate for PCB trace IR drop in remote-sensing configurations. |
| OUTF | Force output | Low-impedance 2.5V source driving the load; shorted to OUTS near the load to achieve <0.01% accuracy under varying PCB copper resistance. |
Key Features
| Feature | Design Value |
|---|---|
| Force/Sense architecture | Eliminates voltage error from PCB trace resistance up to 100mΩ - preserves ±0.04% accuracy even with 2-inch routing to ADC reference pins. |
| Integrated filter pin | Enables configurable wideband noise reduction: 30nV/√Hz spectral density with 0.1µF CFILTER - cuts switching regulator noise in DC-DC powered data loggers. |
| AEC-Q100 qualified | Validated for automotive Grade 1 (–40°C to +125°C) operation - supports engine control unit (ECU) sensor biasing without derating. |
| Low long-term drift | 16ppm drift over 1000 hours - reduces annual recalibration frequency in medical infusion pump pressure transducer circuits. |
| Capacitive-load stability | Stable with 0.1µF–10µF output capacitors - accommodates ceramic decoupling at ADC inputs and eases layout for mixed-signal SoCs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5025IDR | Higher 3ppm/°C max drift, no filter pin, 100µA IQ, SOIC-8 package | Lacks force/sense outputs and AEC-Q100 rating; better for lab-grade bench instruments than automotive | Select when lowest possible drift outweighs size and automotive compliance needs. |

FAQ
What is the maximum load current supported by the MAX6070AAUT25+T?
The MAX6070AAUT25+T supports ±10mA load current - meaning it can both source and sink up to 10mA while maintaining 2.5V output within specification. This capability allows direct drive of op-amp inputs, ADC reference pins, and small-signal transducers without external buffering, reducing bill-of-materials cost and board area in compact designs.
Does the MAX6070AAUT25+T require an external capacitor on the FILTER pin?
No, the FILTER pin on the MAX6070AAUT25+T is optional: connect a 0.1µF capacitor to ground only if high-frequency noise suppression is needed (e.g., in switch-mode power supply environments). Leaving it unconnected disables the filter function and retains the device's native 4.8µVP-P 1/f noise performance - ideal for low-frequency precision applications like strain gauge bridges.
How does the force/sense (OUTF/OUTS) architecture improve accuracy in the MAX6070AAUT25+T?
The MAX6070AAUT25+T uses separate OUTF (force) and OUTS (sense) pins to eliminate voltage drop errors caused by PCB trace resistance. 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 actively compensates for IR losses up to ~100mΩ, preserving ±0.04% output accuracy regardless of board layout parasitics.
Is the MAX6070AAUT25+T qualified for automotive applications?
Yes, the MAX6070AAUT25+T is AEC-Q100 qualified for automotive Grade 1 (–40°C to +125°C), with full characterization across temperature, lifetime stability (16ppm/1000h), and thermal hysteresis (85ppm). Its force/sense topology and 6ppm/°C max drift make it suitable for engine control, battery management, and ADAS sensor signal chains where reference integrity directly impacts functional safety compliance.
What is the typical startup time for the MAX6070AAUT25+T after enable assertion?
The MAX6070AAUT25+T achieves 0.01% output settling in 75µs when the FILTER pin is left unconnected, or 9.6ms when a 0.1µF capacitor is installed on FILTER. This dual-mode settling behavior allows designers to optimize between speed (for fast-sampling systems) and noise performance (for high-resolution DC measurements), with the enable pin supporting dynamic power gating in battery-operated devices.
