Product details
Overview
MAX6062AEUR-T from Maxim Integrated is a precision, micropower, low-dropout series voltage reference delivering a stable 2.048V output with ±0.24% initial accuracy and 20ppm/°C max temperature coefficient over –40°C to +85°C. It sources up to 5mA or sinks 2mA, draws only 90µA typical supply current, and operates from 2.5V to 12.6V input. It is used in high-accuracy ADC biasing, portable instrumentation, and battery-powered precision analog systems.
For engineers reviewing the MAX6062AEUR-T datasheet, MAX6062AEUR-T pinout, MAX6062AEUR-T application, or MAX6062AEUR-T equivalent, this page provides verified specifications, SOT23-3 package details, real-world load regulation (0.5–0.9 mV/mA), dropout behavior (≤200mV at 1mA), noise performance (22µVp-p, 0.1Hz–10Hz), and validated alternatives for precision voltage reference selection.
Technical Context
The MAX6062AEUR-T is a three-terminal, series-mode voltage reference employing proprietary curvature-correction circuitry and laser-trimmed thin-film resistors to achieve high initial accuracy and ultra-low thermal drift. Its internal compensation eliminates need for external capacitors, enabling stable operation with capacitive loads up to 1µF.
It features supply-current independence (±8µA/V variation), low dropout (200mV max at 1mA), and robust line regulation (33–200 µV/V). Designed for space-constrained, battery-operated systems, it delivers 2.048V - a standard reference for 12-bit ADCs - with hysteresis of 130ppm and long-term stability of 62ppm/1000hr.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.048V ±0.24% (max) at +25°C - matches common 12-bit ADC full-scale reference requirement |
| Temp. Coefficient | 20ppm/°C (max) - ensures ≤±1.7mV drift across –40°C to +85°C operating range |
| Quiescent Current | 90µA (typ), ≤125µA (max) - enables multi-year battery life in low-power sensor nodes |
| Dropout Voltage | 200mV (max) at 1mA load - supports operation down to VIN = 2.248V, ideal for single-cell Li-ion or 3V systems |
| Load Regulation | 0.5–0.9 mV/mA - maintains tight output stability under dynamic load changes in data acquisition circuits |
| Noise (0.1–10Hz) | 22µVp-p - low enough to avoid degrading ENOB in 14-bit+ SAR or delta-sigma ADCs |
| Line Regulation | 33–200 µV/V - minimizes output shift when powered from unregulated or noisy supplies |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3420ARJZ-R7 | 2.048V, ±0.1% initial accuracy, 30ppm/°C max, 120µA IQ, SOT23-3 | Higher initial accuracy but worse tempco and higher quiescent current; requires 1µF output cap for stability | Preferred when tighter initial tolerance is prioritized over temperature stability and ultra-low power |
| REF3020AIDBZR | 2.048V, ±0.2% initial accuracy, 50ppm/°C max, 40µA IQ, SOT23-3 | Lower quiescent current but significantly higher tempco; not suitable for wide-temperature industrial use | Selected for ultra-low-power applications where ambient temperature is tightly controlled (e.g., indoor IoT) |

FAQ
What is the output voltage tolerance of MAX6062AEUR-T at +25°C?
The MAX6062AEUR-T has an output voltage of 2.048V with ±0.24% initial accuracy at +25°C, corresponding to a min/max range of 2.043V to 2.053V per the datasheet's MAX6062A grade specification. This tolerance is laser-trimmed and guaranteed across production units.
Does MAX6062AEUR-T require an external output capacitor?
No, MAX6062AEUR-T does not require an external output capacitor due to internal compensation. It remains stable with capacitive loads from 0 to 1µF. Adding a 0.1µF ceramic capacitor is optional and improves transient response in high-dynamic-load applications.
What is the minimum input voltage required for MAX6062AEUR-T to regulate properly?
The minimum input voltage for MAX6062AEUR-T is 2.5V, as specified in the Absolute Maximum Ratings and Electrical Characteristics tables. At 1mA load, dropout is ≤200mV, so regulation is maintained down to VIN = 2.248V - though 2.5V is the guaranteed operational lower limit.
Can MAX6062AEUR-T sink current, and how much?
Yes, MAX6062AEUR-T can sink up to 2mA of load current while maintaining output regulation. This capability allows it to serve as a reference for circuits requiring bidirectional current flow, such as certain DAC buffer configurations or active filter bias networks.
How does the temperature coefficient of MAX6062AEUR-T compare to other 2.048V references?
MAX6062AEUR-T achieves 20ppm/°C (max) temperature coefficient - among the lowest in its class for SOT23-packaged 2.048V references. This outperforms alternatives like REF3020AIDBZR (50ppm/°C) and matches high-precision competitors while retaining micropower operation and capacitor-free design.
