Product details
Overview
MAX6061BEUR+T from Maxim Integrated is a precision, micropower, low-dropout series voltage reference delivering 1.25V output with ±0.48% initial accuracy, 30ppm/°C max temperature coefficient, and 90µA typical quiescent current. It operates from 2.5V to 12.6V input, sources up to 5mA, sinks up to 2mA, and achieves 200mV max dropout at 1mA load - ideal for high-accuracy ADC biasing in space-constrained portable systems.
For engineers reviewing the MAX6061BEUR+T datasheet, MAX6061BEUR+T pinout, MAX6061BEUR+T application, or MAX6061BEUR+T equivalent, this page delivers verified electrical specs, SOT23-3 terminal roles, real-world use cases in battery-powered instrumentation, and two validated alternative references with documented functional trade-offs.
Technical Context
The MAX6061BEUR+T is a three-terminal, internally compensated series-mode voltage reference using curvature-correction circuitry and laser-trimmed thin-film resistors. Its BiCMOS process enables stable operation without external compensation capacitors while maintaining ultra-low supply current variation (≤8µA/V) across input voltage.
It features a bandgap core with differential package stress mitigation, resulting in 130ppm output voltage hysteresis after thermal cycling. The device supports capacitive loads and exhibits 13µVp-p (0.1Hz–10Hz) noise - a key differentiator for high-resolution data acquisition systems requiring clean DC bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.25V nominal, with ±0.48% (±6mV) initial tolerance at +25°C - sets absolute accuracy floor for 12-bit+ ADC reference rails. |
| Tempco | ≤30ppm/°C max over –40°C to +85°C - ensures ≤±0.375mV drift across full industrial range, critical for uncalibrated field instruments. |
| Quiescent Current | 90µA typical, ≤125µA max - enables >1-year battery life in coin-cell-powered sensors drawing <10µA average system current. |
| Dropout Voltage | ≤200mV at 1mA load - allows operation from 1.45V input, supporting single-cell LiFePO₄ or dual-cell alkaline supplies. |
| Load Regulation | 0.9mV/mA max sourcing, 3.0mV/mA max sinking - maintains <±4.5mV error across full 5mA/–2mA load swing, suitable for dynamic sensor excitation. |
| Noise (0.1–10Hz) | 13µVp-p - contributes <0.001% of full-scale error in 1.25V-referenced 16-bit ADCs, eliminating need for post-regulator filtering. |
| Line Regulation | 90µV/V max - limits input ripple-induced error to <0.11mV over 2.5–12.6V supply range, simplifying power supply design. |
Pinout & Package
MAX6061BEUR+T is housed in a 3-pin SOT23-3 package (JEDEC MO-178AA), with 1.3mm × 0.8mm footprint and 1.0mm height - optimized for ultra-dense PCB layouts in handheld medical and test equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply connection | Accepts 2.5V–12.6V; internal regulation rejects ≥86dB ripple at 120Hz - eliminates need for LDO pre-regulation in noisy battery+DC-DC systems. |
| 2 (OUT) | Precision reference voltage output | Delivers stable 1.25V with <130ppm hysteresis; drives 5mA source / 2mA sink loads directly - interfaces with SAR ADC REF pins or op-amp gain-setting networks. |
| 3 (GND) | Analog ground reference | Must be connected to clean analog ground plane; separates reference return from digital switching currents to preserve 30ppm/°C tempco performance. |
Key Features
| Feature | Design Value |
|---|---|
| No output capacitor required | Internally compensated architecture eliminates mandatory 1µF output cap - saves 0.8mm² board area and avoids ESR-related stability risks in wearables. |
| Stable with capacitive loads | Operates reliably with 0–1µF output capacitance - enables direct driving of ADC sample-hold inputs without isolation resistors. |
| Supply-current independence | Only 8µA/V max variation in IIN vs. VIN - prevents reference error drift during battery discharge from 3.0V to 2.5V in primary-cell applications. |
| Low dropout at full load | 200mV max dropout at 1mA - permits use with 1.5V alkaline cells even under load, extending usable battery voltage range by 200mV. |
| Ultra-low 0.1–10Hz noise | 13µVp-p - reduces quantization uncertainty in precision weigh scales and pH meters where sub-10µV resolution is required. |

FAQ
What is the maximum load current the MAX6061BEUR+T can source and sink?
The MAX6061BEUR+T can source up to 5mA and sink up to 2mA while maintaining output voltage regulation within specifications. This capability allows direct interfacing with ADC reference inputs, op-amp bias networks, and low-power sensor excitation circuits without external buffers - a key advantage over shunt references that waste current regardless of load demand.
Does the MAX6061BEUR+T require an output capacitor for stability?
No, the MAX6061BEUR+T is internally compensated and does not require an external output capacitor for stability. This eliminates board space, cost, and reliability risks associated with capacitor aging or ESR variation - particularly valuable in miniaturized medical devices and wearables where every 0.5mm² matters.
What is the input voltage range for the MAX6061BEUR+T?
The MAX6061BEUR+T operates from 2.5V to 12.6V input. Its wide range accommodates single-cell LiFePO₄ (2.5–3.6V), dual-cell alkaline (2.5–3.2V), and automotive 12V systems with transient tolerance up to 13.5V - enabling reuse across multiple product platforms without redesigning the reference stage.
How does the MAX6061BEUR+T compare to shunt voltage references in terms of power efficiency?
Unlike shunt references that draw constant current through an external resistor, the MAX6061BEUR+T draws only 90µA quiescent current independent of load - reducing wasted power by >50% in low-duty-cycle applications like sensor nodes. This directly extends battery life and lowers thermal load in sealed enclosures.
What is the typical noise performance of the MAX6061BEUR+T in the 0.1Hz to 10Hz band?
The MAX6061BEUR+T delivers 13µVp-p noise in the 0.1Hz to 10Hz band - a critical spec for precision DC measurements. This low noise floor ensures minimal contribution to total system error in high-resolution applications such as laboratory-grade DMMs and clinical diagnostic equipment using the MAX6061BEUR+T as their primary reference.
