Product details
Overview
MAX6004EUR-T from Analog Devices is a precision 4.096V series voltage reference in SOT23-3 package, designed for low-power, wide-input-voltage battery-operated systems. It delivers ±0.75% initial accuracy (±31mV), 100ppm/°C max temperature coefficient, and 100mV dropout at 400µA load-enabling stable operation in portable medical sensors and handheld test equipment.
For engineers reviewing the MAX6004EUR-T datasheet, MAX6004EUR-T pinout, MAX6004EUR-T application, or MAX6004EUR-T equivalent, this page provides verified electrical specs, real-world application context, validated alternatives, and supply-chain support details specific to the MAX6004EUR-T variant-not the broader MAX6001–MAX6005 family.
Technical Context
The MAX6004EUR-T is a bandgap-based series voltage reference with internal compensation, eliminating need for external capacitors across its 0–2.2nF stable load range. Its architecture enables sourcing and sinking up to ±400µA while maintaining <0.2% output deviation over input voltage variations from (VOUT + 200mV) to 12.6V.
It operates across –40°C to +85°C with 130ppm hysteresis and 50ppm/1000hrs long-term stability. Supply current remains tightly regulated at 27–45µA, varying only 0.8µA/V with input voltage-critical for energy-constrained applications where quiescent power must be predictable and minimal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±31mV (±0.75% initial accuracy at +25°C) |
| Temperature Coefficient | ≤100ppm/°C - ensures ≤±0.33mV/°C drift over –40°C to +85°C |
| Quiescent Supply Current | 27µA to 45µA - ultra-low static draw for multi-year battery life |
| Dropout Voltage | 100mV at 400µA load - supports operation down to 4.196V input in 4.3V systems |
| Load Regulation | 0.20µV/µA - maintains <80µV shift across full ±400µA output current range |
| Line Regulation | 25µV/V - limits output change to <312µV over 12.4V input swing (4.296V to 12.6V) |
| Noise (0.1–10Hz) | 100µVP-P - suitable for 12-bit ADC references without additional filtering |
Pinout & Package
SOT23-3 plastic surface-mount package (2.92mm × 1.3mm × 1.02mm), JEDEC MO-178AA compliant, with gull-wing leads and exposed pad not connected internally.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Supply Voltage Input | Accepts (VOUT + 0.2V) to 12.6V; supplies internal bandgap core and output stage |

| 3 (GND) | Ground Reference | Return path for supply and load currents; must be low-impedance for noise control |
Key Features
| Feature | Design Value |
|---|---|
| Zero external capacitor required | Stable with CLOAD = 0 to 2.2nF - saves PCB area and BOM cost in space-constrained designs |
| Low dropout at full load | 100mV @ 400µA - enables use in 4.2V Li-ion systems without LDO pre-regulation |
| Supply current independence | 0.8µA/V variation - eliminates input-voltage-dependent power budget uncertainty |
| Bipolar output capability | ±400µA sink/source - supports active load regulation and bidirectional calibration circuits |
| Turn-on settling time | 160µs to 0.1% - meets fast-wake-up timing in duty-cycled sensor nodes |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3440ARJZ-R7 | 4.096V output, 10ppm/°C TC, 45µA IQ, but requires 1µF output cap for stability | Higher precision needed in metrology-grade instruments; less suitable for ultra-small PCBs | Select when TC <20ppm/°C is mandatory and board space permits 1µF ceramic cap |
| REF3040AIDBZR | 4.096V output, 50ppm/°C TC, 50µA IQ, stable with 0–10nF load, but 200mV dropout at 400µA | Used in industrial PLC analog I/O modules where higher dropout is acceptable for cost reduction | Select when wider input margin exists and lower TC is prioritized over minimal dropout |
Compared with ADR3440ARJZ-R7 and REF3040AIDBZR, the MAX6004EUR-T offers the lowest dropout (100mV) and zero-capacitor operation-making it optimal for size- and input-voltage-constrained portable designs where 100ppm/°C TC is sufficient.

FAQ
What is the maximum input voltage for MAX6004EUR-T?
The MAX6004EUR-T supports an input voltage range from (VOUT + 200mV) = 4.296V up to 12.6V. Absolute maximum rating is +13.5V on the IN pin, but operation above 12.6V is not guaranteed per specifications. For reliable long-term performance, VIN should remain within the 4.296V–12.6V range specified in the Electrical Characteristics table for MAX6004.
Does MAX6004EUR-T require an output capacitor?
No, the MAX6004EUR-T is internally compensated and stable with capacitive loads from 0 to 2.2nF. An external capacitor is optional and only recommended in applications subject to rapid load or supply transients-where it reduces overshoot and improves transient response. In space-constrained designs like wearable sensors, omitting the capacitor is fully supported and commonly implemented.
What is the load current capability of MAX6004EUR-T?
The MAX6004EUR-T can source up to +400µA and sink up to –400µA while maintaining output voltage error within ±0.2% of 4.096V. This bipolar capability supports active load configurations, such as driving op-amp inputs or calibrating ratiometric sensor bridges, without requiring external buffering.
How does temperature hysteresis affect MAX6004EUR-T in field use?
MAX6004EUR-T exhibits ≤130ppm temperature hysteresis-meaning its +25°C output voltage may shift by up to ±0.53mV after cycling between –40°C and +85°C. In field-deployed devices like environmental loggers, this represents a one-time offset that remains stable until the next thermal cycle; it does not accumulate over repeated cycles.
Is MAX6004EUR-T pin-compatible with other MAX600x variants?
Yes, all MAX6001–MAX6005 variants-including MAX6004EUR-T-share identical SOT23-3 pinout (IN, OUT, GND), same footprint, and compatible biasing requirements. Swapping between MAX6001 (1.25V), MAX6002 (2.5V), MAX6003 (3.0V), MAX6004 (4.096V), and MAX6005 (5.0V) requires only a bill-of-materials update; no PCB revision is needed.
