Product details
Overview
MAX6004EUR+T from Analog Devices is a precision 4.096V low-dropout series voltage reference in SOT23-3 package, designed for battery-powered systems requiring stable reference voltage with ultra-low quiescent current (45µA max), 100ppm/°C max temperature coefficient, and 100mV dropout at 400µA load. It serves as the core reference source in portable instrumentation, data converters, and power-supply monitoring circuits.
For engineers reviewing the MAX6004EUR+T datasheet, MAX6004EUR+T pinout, MAX6004EUR+T application, or MAX6004EUR+T equivalent, key selection criteria include output accuracy (±0.7% over temperature), capacitive-load stability (0–2.2nF), line regulation (25µV/V), and compatibility with wide-input-voltage operation (4.296V to 12.6V).
Technical Context
The MAX6004EUR+T implements a bandgap-based series voltage reference architecture with internal compensation, eliminating external capacitors. Its supply current remains stable across input voltage (0.8µA/V variation) and load conditions (±400µA sourcing/sinking capability), enabling direct integration into space-constrained, low-power signal chains.
It delivers 4.096V nominal output with guaranteed initial accuracy of ±1%, operates from –40°C to +85°C, and achieves 0.1% settling in 160µs. The device supports stable operation without output capacitance but maintains performance up to 2.2nF load capacitance-critical for ADC reference buffering and noise-sensitive analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±0.7% over full temperature range - ensures accurate scaling for 12-bit ADCs and DACs |
| Initial Accuracy | ±1% at +25°C - enables calibration-free operation in cost-sensitive portable devices |
| Temp Coefficient | ≤100ppm/°C - limits drift to <±0.35mV over –40°C to +85°C for stable sensor biasing |
| Quiescent Current | 45µA max - extends battery life in always-on monitoring applications |
| Dropout Voltage | 100mV at 400µA load - allows operation from 4.296V input in 3.3V/5V systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3040AIDBZR | 4.096V output, 50ppm/°C max tempco, 50µA quiescent current, SOT23-3 | Lower tempco but higher supply current; requires 1µF output cap for stability | Preferred where tighter temperature drift is critical and board space permits capacitor |
| ADR3440ARJZ-R7 | 4.096V output, 30ppm/°C max tempco, 120µA quiescent current, SOT23-6 | Superior accuracy and lower noise, but larger package and higher power draw | Selected for high-precision lab-grade instruments where size and battery life are secondary |
Compared with REF3040AIDBZR and ADR3440ARJZ-R7, the MAX6004EUR+T offers the lowest quiescent current and smallest footprint among 4.096V references, making it optimal for volume production of space- and power-constrained portable electronics - while trading minor tempco margin for significant system-level efficiency gains.

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. This wide range allows direct use with unregulated sources such as Li-ion batteries or buck converter outputs without additional regulation stages. Operation above 12.6V risks permanent damage per absolute maximum ratings.
Does MAX6004EUR+T require an external output capacitor?
No, the MAX6004EUR+T is internally compensated and stable with output capacitance from 0 to 2.2nF. An external capacitor is optional and only recommended in applications subject to fast load or supply transients - for example, to reduce overshoot during ADC sampling bursts. Its omission saves board area and BOM cost.
What is the load current capability of MAX6004EUR+T?
The MAX6004EUR+T can source and sink up to ±400µA while maintaining specified accuracy and dropout voltage. This bidirectional capability supports both active pull-up and pull-down configurations - essential for driving op-amp inputs, ADC reference pins, or precision current sources in ratiometric sensor systems.
How does temperature affect the output voltage of MAX6004EUR+T?
The MAX6004EUR+T has a maximum temperature coefficient of 100ppm/°C, meaning its output voltage drifts no more than ±0.41mV over the full –40°C to +85°C range. Combined with 130ppm hysteresis and 50ppm/1000hrs long-term stability, this ensures predictable, repeatable performance in field-deployed equipment.
Can MAX6004EUR+T be used in negative-reference configurations?
Yes - the MAX6004EUR+T can generate a negative reference when paired with a charge-pump inverter like the MAX681, as shown in the official application circuit (Figure 1). In that configuration, it provides the positive reference leg while the inverter creates the complementary negative rail, enabling true bipolar operation from a single 3V or 5V supply.
