Product details
Overview
MAX6034AEXR41+T from Maxim Integrated is a precision, micropower, low-dropout series voltage reference delivering 4.096V output with ±0.2% initial accuracy, 30ppm/°C max temperature coefficient, and 200mV max dropout at 1mA load - designed for high-accuracy ADC/DAC biasing in space-constrained, battery-powered systems.
For engineers reviewing the MAX6034AEXR41+T datasheet, MAX6034AEXR41+T pinout, MAX6034AEXR41+T application, or MAX6034AEXR41+T equivalent, key selection criteria include ultra-low 90µA supply current, SC70-3 package compatibility, 0–1µF capacitive-load stability without external compensation, and guaranteed operation across –40°C to +85°C.
Technical Context
The MAX6034AEXR41+T employs a proprietary curvature-corrected bandgap core with laser-trimmed thin-film resistors to achieve <30ppm/°C TC and ±0.2% initial tolerance. Its series-mode architecture eliminates external bias resistors and enables supply-current independence (≤16µA/V variation) over input voltages from 4.296V to 5.5V.
This device operates as a fixed-output, internally compensated voltage reference with no need for output capacitance - stable from 0 to 1µF load capacitance while sourcing up to 1mA and sinking up to 200µA. Turn-on settling time is 260µs to 0.1% with 50pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±0.2% (±8.2mV) - ensures 12-bit ADC full-scale accuracy over temperature without calibration. |
| Temperature Coefficient | ≤30ppm/°C - limits drift to ≤12.3ppm over 0°C–70°C industrial range, critical for precision data acquisition. |
| Dropout Voltage | ≤200mV at 1mA load - enables operation from 4.296V supply, supporting single-cell Li-ion or dual-cell alkaline systems. |
| Supply Current | 95–125µA (typ 95µA) - ultra-low quiescent draw extends battery life in portable instrumentation. |
| Load Regulation | ≤1.5mV/mA sourcing, ≤9.8mV/mA sinking - maintains reference stability under dynamic load transients in sensor front-ends. |
| Noise (10Hz–10kHz) | 105µVRMS - low enough for 16-bit SAR ADCs without additional filtering. |
| Capacitive Load Stability | 0–1µF - eliminates need for output capacitor, saving PCB area in wearables and IoT nodes. |
Pinout & Package
MAX6034AEXR41+T is housed in a 3-pin SC70 surface-mount package (2.0mm × 2.1mm × 0.9mm), optimized for high-density PCB layouts and reflow-compatible assembly.
| 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 | Provides stable 4.096V output; directly interfaces with ADC REF pins or op-amp feedback networks. |
| 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 - reduces board area by >50% vs. SOT23-3 in portable medical sensors. |
| No external compensation capacitor | Internally compensated for 0–1µF load - eliminates BOM item and layout risk in space-critical designs. |
| Supply-current independence | ≤16µA/V variation - simplifies power budgeting across varying battery voltages in field-deployed equipment. |
| Low dropout at full load | 200mV max at 1mA - supports operation down to 4.296V supply, enabling direct connection to regulated LDO outputs. |
| Extended temperature range | –40°C to +85°C operation - qualified for industrial control and automotive cabin electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3440BRJZ-R7 | 4.096V output, ±0.1% initial accuracy, 30ppm/°C TC, but 125µA supply current and requires 1µF output cap for stability. | Better initial accuracy but higher quiescent current and mandatory output capacitor limit use in ultra-low-power or space-constrained designs. | Prefer when absolute initial tolerance is prioritized over board area and supply current. |
| REF3340AIDBVR | 4.096V output, ±0.2% initial accuracy, 30ppm/°C TC, 80µA supply current, but only stable up to 10nF load capacitance - requires external compensation network. | Lower supply current than MAX6034AEXR41+T but incompatible with >10nF loads without added components, increasing design complexity. | Choose when minimal supply current is critical and output capacitance can be strictly controlled below 10nF. |
Compared with ADR3440BRJZ-R7 and REF3340AIDBVR, the MAX6034AEXR41+T uniquely combines ±0.2% accuracy, 30ppm/°C TC, sub-100µA supply current, and unconditional 0–1µF capacitive-load stability - making it the only option that eliminates both external capacitors and layout-sensitive compensation networks in compact battery-powered systems.

FAQ
What is the maximum input voltage for MAX6034AEXR41+T?
The MAX6034AEXR41+T has an absolute maximum input voltage of +6.0V referenced to GND. However, its specified operating input range is (VOUT + 200mV) to 5.5V - meaning 4.296V to 5.5V for the 4.096V output version. Operation above 5.5V violates the guaranteed electrical specifications and may impact long-term reliability.
Does MAX6034AEXR41+T require an output capacitor for stability?
No, the MAX6034AEXR41+T is internally compensated and stable with output capacitance ranging from 0 to 1µF - including no capacitor. This eliminates the need for external output capacitance in most applications, reducing BOM count and PCB area. An output capacitor may still be added to improve transient response under large load steps.
What is the dropout voltage specification for MAX6034AEXR41+T at 1mA load?
The MAX6034AEXR41+T has a maximum dropout voltage of 200mV at 1mA sourcing load, defined as the minimum (VIN – VOUT) differential required to maintain VOUT within 0.2% of its nominal value. At room temperature and typical conditions, dropout is typically 70mV - enabling efficient operation from low-headroom supplies like 4.3V LDO outputs.
Can MAX6034AEXR41+T sink current, and how much?
Yes, the MAX6034AEXR41+T can sink up to 200µA while maintaining regulation. This capability supports applications such as biasing current-sink DACs or driving low-power logic inputs. Sinking performance is characterized with ≤9.8mV/mA load regulation and remains stable across the full –40°C to +85°C temperature range.
What is the long-term stability of MAX6034AEXR41+T?
The MAX6034AEXR41+T exhibits ≤90ppm drift over 1000 hours at +25°C, measured as change in output voltage relative to initial value. This corresponds to approximately ±0.37mV for the 4.096V output - confirming suitability for applications requiring multi-year calibration stability without field recalibration, such as industrial monitoring nodes.
