Product details
Overview
MAX6034BEXR41-T from Maxim Integrated is a precision, low-dropout, micropower 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 analog signal chains in space-constrained, battery-powered systems.
For engineers reviewing the MAX6034BEXR41-T datasheet, MAX6034BEXR41-T pinout, MAX6034BEXR41-T application, or MAX6034BEXR41-T equivalent, this page provides verified specifications, SC70-3 package details, load regulation behavior, noise performance (105µVRMS, 10Hz–10kHz), and real-world selection guidance against comparable references.
Technical Context
The MAX6034BEXR41-T employs a proprietary curvature-corrected bandgap core with laser-trimmed thin-film resistors to achieve stable 4.096V output across –40°C to +85°C. Its series-mode architecture eliminates external resistor requirements and enables supply-current independence (≤16µA/V variation) over input voltages from 4.296V to 5.5V.
This device operates as a three-terminal active reference: IN supplies regulated current to the internal bandgap circuit, OUT delivers a precise 4.096V reference, and GND establishes the return path. It sources up to 1mA and sinks up to 200µA while maintaining stability with 0–1µF capacitive loads - no external compensation capacitor needed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±0.4% (max initial error = ±16.4mV at +25°C) |
| Temperature 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 (ultra-low quiescent draw; ideal for multi-year battery life) |
| Noise (10Hz–10kHz) | 105µVRMS (supports 16-bit ADCs without additional filtering) |
| Load Regulation | 3.4–9.8mV/mA (output shift ≤ ±9.8mV when sourcing 1mA or sinking 200µA) |
| Capacitive Load Stability | 0–1µF (enables direct connection to ADC reference inputs or LDO feedback nodes) |
Pinout & Package
MAX6034BEXR41-T is housed in a 3-pin SC70 surface-mount package (2.0mm × 2.1mm × 0.9mm), optimized for PCB area-constrained designs such as portable medical sensors and IoT edge nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Supply Voltage Input | Accepts 4.296V–5.5V input; requires local 0.1µF ceramic bypass for optimal line transient rejection |
| 2 - OUT | Reference Voltage Output | Delivers stable 4.096V; directly drives ADC reference pins, DAC bias networks, or comparator thresholds |
| 3 - GND | Ground Reference | Low-impedance return path; must be connected to clean analog ground plane to minimize noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small SC70-3 package | 2.0mm × 2.1mm footprint saves >60% board area vs. SOT23-3 in portable designs |
| No external compensation capacitor | Eliminates one BOM item and layout complexity while supporting 0–1µF load capacitance |
| Supply-current independence | Variation ≤16µA/V ensures predictable battery drain across VIN range (4.296V–5.5V) |
| Low dropout (200mV @ 1mA) | Enables operation from single Li-ion cell (3.0V min) with LDO pre-regulation or from 5V rails with minimal headroom |
| Stable under dynamic load | Maintains regulation during ±1mA/±200µA load steps; overshoot <10mV with 1µF CLOAD |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3440BRJZ-R7 | 4.096V output, ±0.1% initial accuracy, 30ppm/°C TC, 120µA supply current, SOT-23-3 package | Higher accuracy and lower TC, but larger footprint and higher cost; requires 1µF output cap for stability | Select when 16-bit+ system accuracy demands tighter initial tolerance and TC, and board area permits SOT-23 |

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 functional operating range is specified as VOUT + 0.2V (i.e., 4.296V) up to 5.5V. Operating above 5.5V violates the guaranteed electrical characteristics and may impact long-term reliability. The MAX6034BEXR41-T datasheet confirms this limit under "Supply Voltage Range" in the Electrical Characteristics table.
Does MAX6034BEXR41-T require an output capacitor?
No, MAX6034BEXR41-T does not require an output capacitor for stability - it is internally compensated and remains stable with load capacitance from 0 to 1µF. An optional 1µF ceramic capacitor can improve transient response during large load steps, but omitting it saves board space and BOM cost. This behavior is explicitly stated in the "Features" and "Applications Information" sections of the MAX6034BEXR41-T datasheet.
What is the load current capability of MAX6034BEXR41-T?
MAX6034BEXR41-T can source up to 1mA and sink up to 200µA while maintaining output regulation within specification. Sourcing capability supports driving ADC reference inputs or op-amp bias networks; sinking capability enables use in current-source configurations or active pull-down circuits. These values are confirmed in the "Electrical Characteristics" table for MAX6034_41 under "Load Regulation" and "OUT Short-Circuit Current".
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 ±0.00041V after cycling between –40°C and +85°C. This effect arises from mechanical stress in the package affecting the bandgap core and is independent of TC. For systems requiring recalibration only at power-up (not per thermal cycle), this hysteresis contributes less than 0.01% error - well within 12-bit accuracy budgets.
Can MAX6034BEXR41-T be used with a 3.3V supply rail?
No - MAX6034BEXR41-T requires a minimum input voltage of VOUT + 200mV = 4.296V for proper regulation at full load. A 3.3V rail falls 996mV below this threshold and will cause the device to drop out of regulation, resulting in uncontrolled output voltage. To use MAX6034BEXR41-T with a 3.3V system, a boost converter or LDO generating ≥4.3V must precede it. This requirement is defined in the "Selector Guide" and "Electrical Characteristics" tables for MAX6034_41.
