Product details
Overview
MAX6062AEUR+T from Maxim Integrated is a precision 2.048V, low-dropout, micropower series voltage reference in a 3-pin SOT23 package. It delivers ±0.24% initial accuracy, 20ppm/°C max temperature coefficient, and supports 5mA source / 2mA sink load current across –40°C to +85°C. It enables high-accuracy ADC biasing in space-constrained, battery-powered instrumentation.
For engineers reviewing the MAX6062AEUR+T datasheet, MAX6062AEUR+T pinout, MAX6062AEUR+T application, or MAX6062AEUR+T equivalent, key selection criteria include its 2.048V output (ideal for 12-bit DAC/ADC full-scale matching), ultra-low 90µA quiescent current, dropout as low as 200mV at 1mA, and elimination of external compensation capacitors - critical for portable medical sensors and handheld test equipment.
Technical Context
The MAX6062AEUR+T employs a proprietary curvature-correction circuit and laser-trimmed thin-film resistors to achieve 20ppm/°C max TCVOUT and ±0.24% initial accuracy over –40°C to +85°C. Its BiCMOS process ensures stable operation without output capacitance while maintaining 86dB ripple rejection at 120Hz.
As a three-terminal series-mode reference, it draws supply current virtually independent of input voltage (3.3µA/V variation), eliminating wasted bias current common in shunt-mode alternatives. Input voltage range is 2.5V to 12.6V, with guaranteed regulation down to VIN = VOUT + 200mV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.048V ±0.24% (max) at +25°C - matches standard 12-bit ADC/DAC full-scale codes without scaling. |
| Temperature Coefficient | 20ppm/°C (max) - ensures ≤±1.7mV drift over –40°C to +85°C for precision sensor signal chains. |
| Quiescent Supply Current | 90µA (typ), ≤125µA (max) - enables >1-year battery life in coin-cell–powered data loggers. |
| Dropout Voltage | 200mV (max) at 1mA load - allows operation from single Li-ion or two alkaline cells with margin. |
| Load Regulation | 0.9mV/mA (max) sourcing - maintains <±0.5mV error across 0–5mA load variation in active bias networks. |
| Line Regulation | 200µV/V (max) - rejects input ripple up to 12.6V without additional filtering in noisy power rails. |
| Noise (0.1Hz–10Hz) | 22µVP-P - contributes <0.01 LSB error in 16-bit 2.048V-range systems. |
Pinout & Package
MAX6062AEUR+T uses a 3-pin SOT23-3 package (JEDEC MO-178AA), 1.45mm × 2.9mm footprint, 1.1mm height, with gull-wing leads. Pin 1 (IN) accepts 2.5V–12.6V input; Pin 2 (OUT) delivers regulated 2.048V; Pin 3 (GND) provides reference ground return.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input Voltage Supply | Accepts unregulated input; requires no external series resistor - unlike shunt references. |
| 2 (OUT) | Reference Output | Provides stable 2.048V output; capable of sourcing 5mA or sinking 2mA directly into load. |
| 3 (GND) | Ground Reference | Low-impedance return path; must be connected to system ground plane for optimal noise performance. |
Key Features
| Feature | Design Value |
|---|---|
| No output capacitor required | Eliminates 0.1µF–1µF ceramic cap, saving ≥1mm² PCB area in wearables and hearing aids. |
| Stable with capacitive loads | Operates reliably with up to 1µF output capacitance - simplifies EMI filtering in mixed-signal PCBs. |
| Supply-current independence | ΔIIN/ΔVIN ≤ 3.3µA/V - avoids dynamic current draw variations that couple noise into analog sections. |
| Low dropout at full load | 200mV max at 1mA - enables use with buck converter outputs as low as 2.25V in ultra-low-power SoC designs. |
| High PSRR | 86dB at 120Hz - suppresses AC line harmonics in portable DMMs and industrial handheld meters. |

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 TCVOUT (50ppm/°C vs. 20ppm/°C); lower IQ but looser drift spec | Preferred where ultra-low power dominates over temperature stability - e.g., sub-10µA sleep-mode nodes. |
| ADR3420ARJZ-R7 | 2.048V, ±0.1% init, 10ppm/°C max, 120µA IQ, SOT23-5 | Tighter initial accuracy and drift, but 5-pin package and higher IQ; requires output cap for stability | Chosen when highest absolute accuracy is mandatory and board space allows 5-pin layout and 1µF cap. |
Compared with REF3020AIDBZR and ADR3420ARJZ-R7, the MAX6062AEUR+T offers the best balance of low drift (20ppm/°C), ultra-low IQ (90µA), and capacitor-free operation in the smallest 3-pin SOT23 footprint - making it optimal for size- and battery-limited 2.048V reference applications.

FAQ
What is the maximum input voltage rating for MAX6062AEUR+T?
The absolute maximum input voltage for MAX6062AEUR+T is +13.5V referenced to GND. However, the guaranteed operating range is 2.5V to 12.6V per the datasheet's electrical characteristics table. Exceeding 12.6V may compromise parametric guarantees, and sustained operation above 13.5V risks permanent damage. Always observe the 200mV minimum headroom (VIN ≥ VOUT + 200mV) for proper regulation.
Does MAX6062AEUR+T require an output capacitor for stability?
No, MAX6062AEUR+T does not require an output capacitor for stability - a key differentiator from many competing references. Its internal compensation ensures unconditional stability even with zero output capacitance. An optional 0.1µF–1µF ceramic capacitor may be added to improve transient response under large load steps, but it is never mandatory for oscillation prevention.
What is the typical turn-on settling time for MAX6062AEUR+T?
The typical turn-on settling time for MAX6062AEUR+T is 115µs to within 0.1% of final output voltage, measured with COUT = 50pF. This value is confirmed in the MAX6062-specific electrical characteristics table on page 4 of the datasheet. Settling time increases with larger output capacitance or higher load currents, reaching up to 1.5ms under worst-case dropout and full-load conditions.
Can MAX6062AEUR+T sink current, and how much?
Yes, MAX6062AEUR+T can actively sink up to 2mA of load current, as specified in its "Load Regulation" test condition (–2mA ≤ IOUT ≤ 0). This capability enables bidirectional biasing - for example, driving current into the reference input of op-amp-based transimpedance amplifiers or calibrating ratiometric sensor bridges where the reference must absorb reverse current during certain phases.
What does the 'A' grade signify in MAX6062AEUR+T?
The 'A' grade in MAX6062AEUR+T denotes ±0.24% maximum initial output voltage accuracy at +25°C, as shown in the ordering guide (2.043V to 2.053V). This is tighter than the 'B' grade (±0.39%, 2.040V to 2.056V). Both grades share identical temperature coefficient (20ppm/°C max), noise, and supply current specs - only the room-temperature trim tolerance differs.
