Product details
Overview
MAX6070DAUT25/V+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 sensor signal conditioning, and automotive-grade precision power rails.
For engineers reviewing the MAX6070DAUT25/V+T datasheet, MAX6070DAUT25/V+T pinout, MAX6070DAUT25/V+T application, or MAX6070DAUT25/V+T equivalent, this device delivers verified low-noise performance in SOT23-6 packaging with integrated filter input, force-sense output architecture, and AEC-Q100 qualification for harsh-environment reliability.
Technical Context
The MAX6070DAUT25/V+T implements a bandgap-based series voltage reference with dual-output force-sense topology (OUTF/GNDF and OUTS/GNDS) to reject PCB trace resistance errors. Its dedicated FILTER pin supports external 0.1µF capacitor bypassing to suppress wideband noise above 10Hz.
It operates across –40°C to +125°C with 2.8V to 5.0V supply range, 150µA typical quiescent current, and ±10mA load capability while maintaining 230mV max dropout at full sink/source load - enabling stable regulation in low-headroom industrial and automotive power domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500V ±0.04% at +25°C - enables direct interface with 12-/16-bit SAR ADCs requiring tight reference tolerance |
| Temp Drift (max) | 6ppm/°C (A grade) - ensures ≤150µV total drift over –40°C to +125°C for <0.01% system error contribution |
| 1/f Noise | 4.8µVP-P (0.1Hz–10Hz) - critical for DC-coupled precision instrumentation and weigh-scale front-ends |
| Supply Current | 150µA typical - allows battery-powered portable test equipment to achieve >10-year shelf life |
| Load Current | ±10mA sourcing/sinking - supports driving 10kΩ DAC reference inputs or multiple op-amp bias networks |
| Ripple Rejection | 84dB at 60Hz - rejects switching regulator coupling without additional LC filtering |
| Dropout Voltage | 230mV max at 10mA - permits operation from 2.73V supply, compatible with LiFePO₄ or 3.3V LDO rails |
Pinout & Package
Package: 6-pin SOT23 (U6+5A outline, RoHS-compliant). Thermal resistance θJA = 230°C/W on multilayer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - FILTER | High-frequency noise filter input | Accepts 0.1µF capacitor to GND; enables 10Hz–10kHz thermal noise reduction to 3.0µVRMS |
| 2 - GNDF | Force ground return | Carries reference output current return path; must be routed separately from noisy system GND |
| 3 - EN | Enable control input | Logic-high (>0.7×VIN) activates reference; logic-low (<0.3×VIN) reduces supply current to 6µA |
| 4 - IN | Supply input | Accepts 2.8V–5.0V; internal LDO structure provides line regulation of 145µV/V (typ) |
| 5 - OUTS | Sense output | Connects to load-side ground reference point; compensates for trace IR drop in remote sensing |
| 6 - OUTF | Force output | Delivers regulated 2.5V; shorted to OUTS near load to close Kelvin feedback loop |
Key Features

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR4525BRZ | No filter pin; 3ppm/°C max drift; 1.8µVP-P noise; SOIC-8 package | Lacks force-sense outputs and enable control; higher accuracy but larger footprint | Select when ultimate drift performance is prioritized over PCB space and dynamic control |

FAQ
What is the maximum allowable supply voltage for MAX6070DAUT25/V+T?
The MAX6070DAUT25/V+T has an absolute maximum supply voltage of +6V, but its specified operating range is 2.8V to 5.0V. Operation above 5.0V is not characterized and may degrade long-term stability or increase dropout voltage beyond datasheet limits. For reliable 2.5V output regulation with 230mV max dropout, maintain VIN ≤ 5.0V per Electrical Characteristics table on page 5 of the datasheet.
Does MAX6070DAUT25/V+T require external capacitors for stability?
Yes - the MAX6070DAUT25/V+T requires a minimum 0.1µF ceramic capacitor from OUTF to GNDF for stability across its full ±10mA load range. Additionally, a 0.1µF capacitor from FILTER to GND is required to activate the high-frequency noise filter function. The device remains stable with capacitive loads from 0.1µF to 10µF, supporting common decoupling practices without oscillation risk.
How does the force-sense architecture of MAX6070DAUT25/V+T improve accuracy?
The MAX6070DAUT25/V+T uses separate OUTF (force) and OUTS (sense) pins to close a Kelvin feedback loop at the load. This architecture measures voltage directly at the load point via OUTS/GNDS, rejecting voltage drop across PCB traces or connectors between the IC and load. As a result, system-level reference error due to trace resistance is eliminated - critical for applications with long interconnects or high-current sensing paths.
Is MAX6070DAUT25/V+T pin-compatible with other MAX607x variants?
Yes - all MAX6070/MAX6071 devices in SOT23-6 (U6+5A) packaging share identical pinout and footprint, including MAX6070DAUT25/V+T. This allows design reuse across output voltages (1.25V–5.0V) and grades (A/B/D), provided external components (e.g., FILTER capacitor) and enable logic timing are verified per variant-specific settling times.
What is the shutdown current consumption of MAX6070DAUT25/V+T?
When the EN pin is driven low, the MAX6070DAUT25/V+T enters shutdown mode with supply current reduced to 0.6µA to 6µA (typ/max), as specified in the Electrical Characteristics table on page 5. This ultra-low shutdown current enables use in always-on automotive modules or battery-backed instrumentation where standby power budget is constrained to single-digit microamps.
