Product details
Overview
MAX6104EUR+T from Maxim Integrated is a 4.096V, low-dropout (50mV at 1mA), micropower (90µA typical) series-mode voltage reference in a 3-pin SOT23 package. It delivers ±0.4% initial accuracy, 75ppm/°C max temperature coefficient, and operates across –40°C to +85°C. It serves as a precision analog reference in battery-powered data converters and portable instrumentation.
For engineers reviewing the MAX6104EUR+T datasheet, MAX6104EUR+T pinout, MAX6104EUR+T application, or MAX6104EUR+T equivalent, this page provides verified electrical parameters, real-world load regulation behavior (0.9mV/mA sourcing), dropout performance at temperature extremes, and validated alternatives for 4.096V reference design reuse.
Technical Context
The MAX6104EUR+T uses a proprietary curvature-correction circuit with laser-trimmed thin-film resistors to achieve low drift. Its series-mode architecture eliminates external biasing resistors and enables supply current virtually independent of input voltage (4–8µA/V variation).
Internally compensated and stable with any capacitive load when sourcing <200µA, it requires no output capacitor-reducing board area. Dropout voltage remains ≤200mV across full –40°C to +85°C range and 1mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±0.4% (±16.4mV) - matches standard 12-bit DAC full-scale reference point |
| Temperature Coefficient | 75ppm/°C max - ensures ≤±312µV drift over –40°C to +85°C span |
| Quiescent Current | 90µA typical - enables >1-year operation on a 200mAh coin cell at 100% duty cycle |
| Dropout Voltage | 50mV at 1mA load - supports operation from 4.146V input, critical for single-cell Li-ion systems |
| Load Regulation | 0.9mV/mA sourcing - maintains <±4.5mV error across 0–5mA load range |
| Line Regulation | 430µV/V max - limits output shift to <±520µV over 4.296V–12.6V input range |
| Noise (10Hz–10kHz) | 50µVRMS - contributes <0.5 LSB error in 16-bit ADC systems with 4.096V full scale |
Pinout & Package
MAX6104EUR+T is housed in a 3-pin SOT23-3 package (JEDEC MO-178AA), 2.9mm × 1.6mm × 1.1mm, with gull-wing leads and exposed pad not connected internally.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input Voltage Supply | Accepts 4.296V to 12.6V; internal LDO structure regulates against input ripple |
| 2 (OUT) | Precision Reference Output | Delivers stable 4.096V; capable of sourcing 5mA or sinking 2mA directly |
| 3 (GND) | Analog Ground Reference | Must be tied to clean system ground; separates reference return from power return paths |

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, ±0.1% initial accuracy, 30ppm/°C TC, 125µA IQ, SOT23-3 | Higher accuracy and lower drift, but 38% higher quiescent current | Select when long-term stability and tighter TC outweigh battery life constraints |
| REF3040AIDBZR | 4.096V output, ±0.2% initial accuracy, 50ppm/°C TC, 100µA IQ, SOT23-3 | Lower TC and better line regulation (150µV/V), but requires 1µF output cap for stability | Select when board space allows 1µF cap and 50ppm/°C TC is mandatory for extended temperature operation |
Compared with ADR3440ARJZ-R7 and REF3040AIDBZR, the MAX6104EUR+T trades 0.3% initial accuracy and 25ppm/°C higher TC for 33% lower quiescent current and zero-output-capacitor operation-making it optimal for ultra-low-power, space-constrained designs where ±0.4% absolute accuracy suffices.

FAQ
What is the maximum load current the MAX6104EUR+T can source while maintaining specification?
The MAX6104EUR+T is specified to source up to 5mA while maintaining its load regulation of 0.9mV/mA and output voltage accuracy. At 5mA, total output deviation remains within ±4.5mV of nominal 4.096V. Exceeding 5mA may cause increased dropout voltage and potential thermal derating in SOT23 package.
Does the MAX6104EUR+T require an output capacitor for stability?
No, the MAX6104EUR+T does not require an output capacitor for stability. It is internally compensated and remains stable with any capacitive load when sourcing less than 200µA. For loads >200µA, stability is maintained with 0–1µF capacitance; no minimum value is mandated.
What is the minimum input voltage required for the MAX6104EUR+T to regulate at 4.096V?
The minimum input voltage is VOUT + 200mV = 4.296V, per the datasheet's input voltage range specification. At 1mA load, dropout is typically 50mV, so 4.146V input sustains regulation-but 4.296V guarantees operation across temperature, process, and load extremes.
How does the MAX6104EUR+T compare to shunt-mode references in battery-powered systems?
Unlike shunt-mode references, the MAX6104EUR+T draws only 90µA quiescent current independent of input voltage-no wasted current through external resistors. This reduces average power consumption by >50% in variable-input systems and eliminates resistor heat dissipation, extending battery life significantly.
Is the MAX6104EUR+T pin-compatible with other devices in the MAX6100–MAX6107 family?
Yes, all MAX6100–MAX6107 variants-including MAX6104EUR+T-are pin-compatible in the 3-pin SOT23-3 package. Pin 1 is IN, Pin 2 is OUT, and Pin 3 is GND across the entire family, enabling drop-in replacement for different output voltages (1.25V to 5.0V).
