Product details
Overview
MAX6061AEUR-T from Maxim Integrated is a precision, low-dropout, micropower series voltage reference delivering 1.248V ±0.2% (max) output with 20ppm/°C (max) temperature coefficient and 13µVp-p (0.1Hz–10Hz) noise. It operates from 2.5V to 12.6V input, sources up to 5mA, sinks up to 2mA, and draws only 90µA typical quiescent current - ideal for high-accuracy ADC biasing in battery-powered instrumentation.
For engineers reviewing the MAX6061AEUR-T datasheet, MAX6061AEUR-T pinout, MAX6061AEUR-T application, or MAX6061AEUR-T equivalent, key selection criteria include initial accuracy, ultra-low supply current independence from VIN, dropout voltage ≤200mV at 1mA, absence of required output capacitor, and SOT23-3 footprint compatibility in space-constrained portable designs.
Technical Context
The MAX6061AEUR-T is a three-terminal, series-mode voltage reference using proprietary curvature-correction circuitry and laser-trimmed thin-film resistors to achieve ±0.2% initial accuracy and 20ppm/°C max TCVOUT across –40°C to +85°C. Its BiCMOS process enables stable operation without external compensation capacitors.
Unlike shunt references, it draws near-constant 90µA supply current (±8µA/V variation), eliminating input resistor waste and enabling efficient operation across wide input ranges. Dropout is specified at 200mV (max) at 1mA load, supporting low-voltage systems down to 2.5V input.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.248V ±0.2% (max) at +25°C - ensures precise ADC full-scale calibration without trimming |
| Temp. Coefficient | 20ppm/°C (max) - limits drift to ±1.7mV over –40°C to +85°C ambient range |
| Quiescent Current | 90µA (typ), ≤125µA (max) - enables >1-year battery life in µA-level standby systems |
| Dropout Voltage | 200mV (max) at 1mA - supports operation from 1.45V effective supply in low-VIN applications |
| Noise (0.1–10Hz) | 13µVp-p - minimizes quantization uncertainty in 16-bit+ SAR and delta-sigma ADCs |
| Load Regulation | 0.9mV/mA (max) sourcing - maintains stability under dynamic sensor or DAC load changes |
| Line Regulation | 90µV/V (max) - rejects ripple and supply variation without additional filtering |
Pinout & Package
MAX6061AEUR-T is housed in a 3-pin SOT23-3 package (JEDEC MO-178AA), with 1.3mm × 0.8mm footprint and 0.95mm height - optimized for ultra-compact PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply terminal | Accepts 2.5V–12.6V; requires no series resistor; bypassing with 0.1µF ceramic improves line transient response |
| 2 (OUT) | Precision reference output | Delivers stable 1.248V; drives capacitive loads directly; no external capacitor needed for stability |
| 3 (GND) | Analog ground reference | Must be connected to clean system ground plane; separates reference return from digital or power ground paths |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 90µA typical, independent of input voltage - eliminates wasted current in always-on sensing nodes |
| No output capacitor required | Fully internally compensated - saves board area and BOM cost in wearables and medical patches |
| Low dropout voltage | 200mV max at 1mA - enables use with single-cell Li-ion (3.0V min) or two-cell alkaline (2.4V min) supplies |
| Stable with capacitive loads | Operates reliably with 0–1µF output capacitance - simplifies layout in noisy mixed-signal environments |
| High output drive capability | Sources 5mA / sinks 2mA - directly biases ADC reference inputs, op-amp gain-setting networks, and sensor excitation circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3412ARJZ-R7 | 1.2V output, ±0.1% initial accuracy, 3ppm/°C max TCVOUT, 125µA IQ, SOT23-5 | Higher accuracy and lower drift, but 5-pin package and higher supply current limit space-constrained 3-pin designs | Select when sub-10ppm/°C drift is mandatory and board area allows SOT23-5; avoid if 3-pin SOT23 footprint is fixed. |
| REF3012AIDBZR | 1.2V output, ±0.2% initial accuracy, 50ppm/°C max TCVOUT, 50µA IQ, SOT23-3 | Lower quiescent current but 2.5× higher tempco; no 1.25V option - requires gain adjustment in ADC interface | Choose for ultra-low-power sleep modes where drift tolerance >50ppm/°C is acceptable; not drop-in for 1.248V systems. |
Compared with ADR3412ARJZ-R7 and REF3012AIDBZR, the MAX6061AEUR-T uniquely balances 1.248V exact output, 3-pin SOT23 compatibility, 20ppm/°C drift, and 90µA supply current - making it optimal for legacy 1.25V ADC architectures where pin count and voltage match are non-negotiable.

FAQ
What is the output voltage tolerance of the MAX6061AEUR-T at room temperature?
The MAX6061AEUR-T has an output voltage of 1.248V with ±0.2% maximum initial accuracy at +25°C, meaning its actual output falls between 1.244V and 1.252V when measured under standard conditions. This tolerance is laser-trimmed during production and applies across the full –40°C to +85°C operating range as specified in the MAX6061AEUR-T datasheet.
Does the MAX6061AEUR-T require an external output capacitor for stability?
No, the MAX6061AEUR-T is internally compensated and does not require an external output capacitor for stability - a key differentiator from many competing references. It remains stable with capacitive loads from 0 to at least 1µF, enabling capacitor-free designs in space-critical applications like hearing aids and implantable sensors where every mm² counts.
What is the minimum input voltage required for the MAX6061AEUR-T to regulate properly?
The MAX6061AEUR-T requires a minimum input voltage of 2.5V to maintain regulation, as specified in its absolute maximum and operating conditions. At 1mA load, its dropout voltage is ≤200mV, so the effective minimum input is VOUT + 200mV = 1.448V - but the 2.5V lower limit ensures performance across all load, temperature, and process corners per the MAX6061AEUR-T production test plan.
How does the supply current of the MAX6061AEUR-T vary with input voltage?
The MAX6061AEUR-T exhibits exceptional supply current stability: its quiescent current varies by only ≤8µA per volt across the 2.5V–12.6V input range, resulting in a total variation of ≤80µA. At +25°C, it draws 90µA typical - rising to no more than 125µA max - making it far more predictable than shunt references whose current scales linearly with VIN.
Can the MAX6061AEUR-T sink current, and if so, how much?
Yes, the MAX6061AEUR-T can both source and sink current. It is rated to sink up to 2mA while maintaining output regulation and specified accuracy. This bidirectional capability allows it to actively absorb current in applications such as precision current-source termination, active filter biasing, or driving low-impedance loads that may pull the reference node below nominal voltage during transients.
