Product details
Overview
MAX6062BEUR from Maxim Integrated is a precision, low-dropout, micropower 2.048V voltage reference in a 3-pin SOT23 package. It delivers ±0.24% initial accuracy, 20ppm/°C max temperature coefficient, and supports ±2mA sink/source load current. Designed for high-accuracy ADC biasing in portable instrumentation and battery-powered data acquisition systems.
For engineers reviewing the MAX6062BEUR datasheet, MAX6062BEUR pinout, MAX6062BEUR application, or MAX6062BEUR equivalent, key selection criteria include output stability over -40°C to +85°C, ultra-low 90µA quiescent current, dropout voltage ≤200mV at 1mA, and absence of required external compensation capacitors.
Technical Context
The MAX6062BEUR is a three-terminal series-mode voltage reference featuring proprietary curvature-correction circuitry and laser-trimmed thin-film resistors. Its BiCMOS process enables stable operation across 2.5V–12.6V input range while maintaining supply-current independence (≤8µA/V variation).
It operates as a fixed-output, internally compensated reference with no external capacitor needed for stability-even under capacitive loads-and achieves 0.1% settling in 115µs with 50pF output capacitance. Output hysteresis is limited to 130ppm after thermal cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.048V ±0.005V (±0.24% initial accuracy at +25°C) |
| Temp Coefficient | ≤20ppm/°C (max) - ensures <±0.17mV drift over -40°C to +85°C |
| Quiescent Current | 90µA typical - enables >1-year battery life in 10µA-systems |
| Dropout Voltage | ≤200mV at 1mA load - supports operation down to VIN = 2.5V |
| Load Current | ±2mA sink / +5mA source - drives ADC reference inputs and op-amp bias networks |
| Noise (0.1–10Hz) | 22µVP-P - preserves ENOB in 16-bit+ SAR and delta-sigma ADCs |
| Line Regulation | 33–200µV/V - minimizes output shift during battery discharge or supply ripple |
Pinout & Package
Package: 3-pin SOT23-3 (JEDEC MO-178AA), 1.4mm × 1.1mm × 1.0mm body, gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply terminal | Accepts 2.5V–12.6V; requires no series resistor; bypass with 0.1µF ceramic if line transients present |
| 2 (OUT) | Precision reference output | Delivers stable 2.048V; directly interfaces to ADC REF+ pins, DAC bias, or op-amp gain-setting networks |
| 3 (GND) | Analog ground reference | Must be connected to clean system AGND; separates reference path from digital return currents |
Key Features
| Feature | Design Value |
|---|---|
| No output capacitor required | Enables direct connection to ADC reference inputs without board-area penalty or stability risk |
| Stable with capacitive loads | Supports 0–1µF output capacitance-critical for noise filtering in portable sensor front-ends |
| Supply-current independence | 90µA ±8µA/V variation - eliminates supply-voltage dependency seen in shunt references |
| Low dropout at full load | 200mV max at 1mA - allows use with single-cell Li-ion (3.0V min) or two-cell alkaline (2.4V min) |
| Laser-trimmed thin-film resistors | Ensures ±0.24% initial accuracy and <130ppm hysteresis after thermal cycling |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3020AIDBZR | 2.048V, ±0.2% init, 50ppm/°C max, 50µA IQ, SOT23-3 | Higher tempco and lower load drive (±1mA); optimized for ultra-low power, not high-accuracy systems | Select when supply current <50µA is critical and tempco tolerance ≥50ppm/°C is acceptable |
| ADR3420ARJZ-R7 | 2.048V, ±0.1% init, 10ppm/°C max, 120µA IQ, SOT23-3 | Superior accuracy/tempco but higher quiescent current and requires 1µF output cap for stability | Select when absolute accuracy and long-term drift dominate over board space and battery life |
Compared with REF3020AIDBZR, MAX6062BEUR offers tighter tempco and higher load drive at modest IQ increase; versus ADR3420ARJZ-R7, it trades 0.1% initial accuracy for guaranteed capacitor-free operation and 30% lower IQ-critical in space-constrained, long-life portable designs.

FAQ
What is the maximum input voltage rating for MAX6062BEUR?
The MAX6062BEUR has an absolute maximum input voltage of +13.5V referenced to GND. However, its specified operating range is 2.5V to 12.6V per the datasheet's electrical characteristics table. Operation above 12.6V is outside guaranteed specifications and may impact long-term reliability or parametric performance.
Does MAX6062BEUR require an external output capacitor for stability?
No, the MAX6062BEUR is internally compensated and does not require an external output capacitor for stability-even with capacitive loads up to 1µF. This eliminates board area, cost, and potential phase-margin issues common in shunt or older series references.
What is the load regulation performance of MAX6062BEUR?
The MAX6062BEUR exhibits 0.5–0.9mV/mA load regulation when sourcing 0–5mA and 1.5–4mV/mA when sinking –2mA to 0mA. This tight regulation ensures minimal output deviation during dynamic load changes in ADC reference or op-amp bias applications.
Can MAX6062BEUR be used in a 1.8V supply system?
No-MAX6062BEUR requires a minimum input voltage of 2.5V. Its dropout voltage is rated ≤200mV at 1mA, so VIN must be ≥2.248V to maintain regulation. For 1.8V systems, consider the MAX6068BEUR (1.8V output) or other sub-2V references.
How does the temperature hysteresis of MAX6062BEUR affect calibration?
The MAX6062BEUR has a maximum output voltage hysteresis of 130ppm after thermal cycling from –40°C to +85°C. At 2.048V, this equals ±0.266mV shift-well within ±0.24% initial accuracy and typically negligible for single-point calibration in industrial or medical devices.
