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, featuring ±0.4% initial accuracy, 75ppm/°C max temperature coefficient, and no external capacitor requirement-designed for precision ADC/DAC biasing in portable battery-powered instrumentation.
For engineers reviewing the MAX6104EUR-T datasheet, MAX6104EUR-T pinout, MAX6104EUR-T application, or MAX6104EUR-T equivalent, this page delivers verified electrical specs, thermal stability data, load/source regulation behavior, dropout performance across temperature, and real-world design implications for space-constrained, low-quiescent-current systems.
Technical Context
The MAX6104EUR-T employs a proprietary curvature-correction circuit with laser-trimmed thin-film resistors to achieve 75ppm/°C max temperature coefficient and ±0.4% max initial accuracy over –40°C to +85°C. It operates as a three-terminal series-mode reference, eliminating dependency on external bias resistors unlike shunt-mode alternatives.
Internally compensated and stable with any capacitive load when sourcing <200µA, it draws only 90µA quiescent current with just 4µA/V supply-voltage variation-enabling direct integration into high-precision, ultra-low-power signal chains without output capacitance overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±0.4% (±16.4mV) at +25°C-matches standard 12-bit full-scale reference for SAR ADCs. |
| Temperature Coefficient | 75ppm/°C max (–40°C to +85°C)-ensures ≤±3.5mV total drift over full industrial range. |
| Dropout Voltage | 50mV at 1mA load-supports operation from 4.146V input, enabling use with single Li-ion or regulated 4.2V rails. |
| Quiescent Current | 90µA typical, 125µA max-minimizes battery drain in always-on sensor nodes and portable DMMs. |
| Load Regulation | 0.9mV/mA (source), 8mV/mA (sink)-maintains stability under dynamic load shifts in mixed-signal SoCs. |
| Noise (0.1–10Hz) | 50µVP-P-low enough for 16-bit ADC reference without additional filtering. |
| Ripple Rejection | 72dB at 120Hz-rejects line-frequency artifacts in AC-powered test equipment. |
Pinout & Package
MAX6104EUR-T is housed in a 3-pin SOT23-3 package (JEDEC MO-178AA), with 1.3mm × 2.9mm footprint and 1.0mm height-optimized for high-density PCB layouts in handheld instruments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input Voltage Supply | Accepts 4.296V to 12.6V; dropout headroom defined relative to VOUT; requires no series resistor. |
| 2 (OUT) | Reference Output | 4.096V precision node; stable without external capacitor; sinks up to 2mA or sources up to 5mA. |
| 3 (GND) | Analog Ground Reference | Low-impedance return path; must be tied directly to system analog ground plane for optimal PSRR. |
Key Features
| Feature | Design Value |
|---|---|
| No output capacitor required | Eliminates 1–10µF ceramic cap, saving >1mm² board area and reducing BOM count in wearables and medical sensors. |
| Stable with capacitive loads | Operates reliably with any CLOAD when IOUT < 200µA; avoids oscillation risk in DAC buffer stages. |
| Ultra-low supply current | 90µA typical, independent of VIN-enables multi-year battery life in remote IoT nodes using coin cells. |
| Low 50mV dropout | Permits direct connection to 4.2V Li-ion batteries even at end-of-discharge (3.4V nominal), extending usable runtime. |
| ±0.4% initial accuracy | Reduces or eliminates factory calibration steps in production test for portable DMMs and data loggers. |

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, ±0.1% initial accuracy, 30ppm/°C TC, 125µA IQ, SOT23-3 | Higher accuracy and lower TC, but 39% higher quiescent current | Select for metrology-grade calibration where long-term stability outweighs battery life impact. |
| REF3040AIDBZR | 4.096V, ±0.2% initial accuracy, 50ppm/°C TC, 50µA IQ, SOT23-3 | Lower IQ and TC, but requires 1µF output capacitor for stability | Select when board area allows capacitor placement and ultra-low IQ is critical for >5-year battery life. |
Compared with ADR3440ARJZ-R7, MAX6104EUR-T trades 0.3% initial accuracy and 45ppm/°C higher TC for 30µA lower IQ and zero-output-capacitor operation; versus REF3040AIDBZR, it sacrifices 0.1% accuracy and 25ppm/°C TC to eliminate capacitor dependency and simplify layout in size-constrained designs.

FAQ
What is the minimum input voltage required for stable operation of the MAX6104EUR-T?
The MAX6104EUR-T requires an input voltage ≥ (VOUT + 200mV) = 4.296V for guaranteed specification compliance across –40°C to +85°C. At 1mA load, its 50mV dropout allows operation down to 4.146V, but full parameter guarantees begin at 4.296V per the datasheet's input voltage range specification.
Does the MAX6104EUR-T require an output capacitor for stability?
No, the MAX6104EUR-T is internally compensated and does not require an external output capacitor for stability. It remains stable with any capacitive load when sourcing less than 200µA. For loads >200µA, avoid 0.5nF–50nF capacitance unless transient response testing confirms stability in the target application.
How does the MAX6104EUR-T compare to shunt-mode references like the TL431 in terms of supply current efficiency?
Unlike the TL431-which requires a series bias resistor and draws constant current regardless of load-the MAX6104EUR-T draws only 90µA quiescent current independent of load. Its supply current varies by just 4µA/V with input voltage, making it significantly more efficient in battery-powered systems where load current is intermittent or variable.
Can the MAX6104EUR-T sink current, and what is its maximum sink capability?
Yes, the MAX6104EUR-T can sink up to 2mA while maintaining output regulation. This bidirectional current capability supports applications such as programmable current sources, active load circuits, and precision bias networks where the reference must absorb current during certain operating phases.
What is the long-term stability specification for the MAX6104EUR-T, and how is it measured?
The MAX6104EUR-T exhibits 50ppm/1000hr long-term stability at +25°C, measured as output voltage drift after 1000 hours of continuous operation. This parameter reflects silicon-level aging behavior and is critical for applications requiring uncalibrated accuracy over extended deployment periods, such as remote environmental monitors.
