Product details
Overview
MAX6034BEXR41+T from Maxim Integrated is a precision, micropower, low-dropout series voltage reference delivering 4.096V output with ±0.4% initial accuracy, 75ppm/°C max temperature coefficient, and 200mV max dropout at 1mA load-designed for high-accuracy data acquisition in battery-powered industrial sensors and portable instrumentation.
For engineers reviewing the MAX6034BEXR41+T datasheet, MAX6034BEXR41+T pinout, MAX6034BEXR41+T application, or MAX6034BEXR41+T equivalent, this page delivers verified specifications, SC70-3 package layout, real-world load/transient behavior, and validated alternative options for precision analog signal chains requiring stable 4.096V reference voltage.
Technical Context
The MAX6034BEXR41+T uses a proprietary curvature-corrected bandgap core with laser-trimmed thin-film resistors to achieve tight initial tolerance and low thermal drift across –40°C to +85°C. Its series-mode architecture eliminates external bias resistors and supports supply-independent quiescent current (95–125µA).
Internally compensated for capacitive loads up to 1µF, it operates without an output capacitor while maintaining stability-critical for space-constrained PCBs. Dropout voltage remains ≤200mV at 1mA sourcing or 200µA sinking, enabling operation from as low as 4.296V input.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±0.4% (max initial error = ±16.4mV at +25°C) |
| Temp Coefficient | 75ppm/°C max (output drift ≤ ±0.026V over –40°C to +85°C) |
| Dropout Voltage | 200mV max at 1mA load (minimum VIN = 4.296V for full regulation) |
| Supply Current | 95–125µA typical (varies ≤16µA/V with input voltage) |
| Load Drive | Sources 1mA / sinks 200µA (supports ADC bias, DAC reference, sensor excitation) |
| Noise (0.1–10Hz) | 90µVP-P (enables 16-bit+ resolution in low-frequency measurement systems) |
| Capacitive Load | Stable with 0–1µF (no mandatory output capacitor saves board area) |
Pinout & Package
MAX6034BEXR41+T is housed in a 3-pin SC70 surface-mount package (2.0mm × 2.1mm × 0.9mm), optimized for ultra-compact layouts in portable and embedded systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Supply Voltage Input | Accepts 4.296V to 5.5V; requires local 0.1µF ceramic bypass for optimal line transient rejection |
| 2 - OUT | Reference Voltage Output | Provides regulated 4.096V; directly drives ADC REF pins, op-amp references, or sensor bridges |
| 3 - GND | Ground Reference | Low-impedance return path; must be connected to clean analog ground plane for noise control |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small SC70-3 package | 2.0mm × 2.1mm footprint enables placement adjacent to high-resolution ADCs without routing congestion |
| No external compensation required | Eliminates output capacitor and associated layout constraints-reduces BOM count and assembly cost |
| Supply-current independence | Quiescent current varies ≤16µA/V across input range-simplifies power budgeting in variable-voltage systems |
| Low 200mV dropout | Enables operation from single Li-ion cell (3.0–4.2V) with LDO pre-regulation or direct use with ≥4.3V rails |
| ±0.4% initial accuracy | Meets calibration-grade requirements for portable multimeters and handheld test equipment without factory trimming |
Applications
| Portable Data Loggers | Industrial Sensor Transmitters |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3040AIDBZR | 4.096V, ±0.2% initial accuracy, 50ppm/°C TC, 120µA IQ, SOT23-3 | Higher accuracy and lower drift-but requires 1µF output cap for stability and has higher 250mV dropout | Select when tighter initial tolerance and lower TC outweigh board space and dropout constraints |
| ADR3440ARJZ-R7 | 4.096V, ±0.1% initial accuracy, 30ppm/°C TC, 120µA IQ, SOT23-3 | Superior accuracy and TC, but 300mV dropout and mandatory 1µF output capacitor limit low-voltage operation | Choose for lab-grade instruments where long-term stability and minimal drift dominate design priorities |
Compared with REF3040AIDBZR and ADR3440ARJZ-R7, the MAX6034BEXR41+T trades minor initial accuracy and TC for significantly lower dropout (200mV vs. ≥250mV), no mandatory output capacitor, and smaller SC70 footprint-making it optimal for space- and voltage-constrained portable systems.

FAQ
What is the maximum input voltage for MAX6034BEXR41+T?
The absolute maximum input voltage for MAX6034BEXR41+T is +6.0V referenced to GND. However, the recommended operating range is VOUT + 0.2V (i.e., 4.296V) to 5.5V. Exceeding 5.5V may degrade long-term reliability or trigger internal protection mechanisms not specified in the datasheet.
Does MAX6034BEXR41+T require an output capacitor?
No, MAX6034BEXR41+T is internally compensated and stable with 0–1µF output capacitance. An output capacitor is optional and only recommended to improve transient response in applications with fast load steps-such as multiplexed ADC sampling or digital switching near the reference node.
What is the load current capability of MAX6034BEXR41+T?
MAX6034BEXR41+T can source up to 1mA and sink up to 200µA while maintaining regulation within specification. At 1mA sourcing, dropout remains ≤200mV; at 200µA sinking, output voltage change is ≤6.2mV (based on 31mV/mA load regulation spec).
How does temperature hysteresis affect MAX6034BEXR41+T performance?
MAX6034BEXR41+T exhibits ≤100ppm temperature hysteresis-meaning its output voltage at +25°C may shift by up to ±0.41mV after cycling between –40°C and +85°C. This is critical for systems requiring repeatable calibration points after thermal stress, such as field-deployed instrumentation.
Can MAX6034BEXR41+T be used with a 3.3V supply rail?
No-MAX6034BEXR41+T requires minimum input voltage of VOUT + 0.2V = 4.296V. A 3.3V rail is insufficient for regulation. It must be powered from ≥4.3V, such as a boosted 3.3V supply, a 4.5V LDO, or direct connection to a 4.5–5.5V system rail.
