Product details
Overview
MAX6064BEUR+T from Maxim Integrated is a precision, low-dropout, micropower series voltage reference delivering a stable 4.096V output with ±0.4% initial accuracy (B-grade), 20ppm/°C max temperature coefficient, and 5mA sourcing capability in a 3-pin SOT23 package. It operates from (VOUT + 0.2V) to 12.6V input, draws only 90µA typical supply current, and requires no external compensation capacitor - making it ideal for high-accuracy ADC biasing in portable instrumentation.
For engineers reviewing the MAX6064BEUR+T datasheet, MAX6064BEUR+T pinout, MAX6064BEUR+T application, or MAX6064BEUR+T equivalent, this page delivers verified electrical parameters, validated SOT23-3 terminal roles, confirmed load regulation (0.5–0.9 mV/mA), dropout behavior (50–200 mV at 1mA), and real-world alternatives for precision 4.096V reference design.
Technical Context
The MAX6064BEUR+T is a three-terminal, series-mode voltage reference using proprietary curvature-correction circuitry and laser-trimmed thin-film resistors to achieve tight initial tolerance and ultra-low thermal drift. Its internal compensation eliminates need for external capacitors, while its supply-current independence (≤8µA/V variation) enables stable operation across wide input voltage ranges without wasted quiescent power.
Designed for high-output-current applications, it sources up to 5mA or sinks up to 2mA while maintaining output stability under capacitive loads. The device supports extended industrial temperature range (−40°C to +85°C) and exhibits 130ppm output voltage hysteresis and 62ppm/1000hr long-term stability - critical for metrology-grade systems requiring repeatable calibration over time.
Key Specifications

FAQ
What is the maximum input voltage rating for MAX6064BEUR+T?
The absolute maximum input voltage for MAX6064BEUR+T is +13.5V referenced to GND. However, the guaranteed operating range is (VOUT + 0.2V) to 12.6V - meaning 4.296V to 12.6V. Exceeding 12.6V may cause parametric degradation, and operation above 13.5V risks permanent damage. Always observe the 12.6V upper limit in normal use of MAX6064BEUR+T.
Does MAX6064BEUR+T require an external output capacitor for stability?
No, MAX6064BEUR+T does not require an external output capacitor for frequency stability - its internal compensation ensures unconditional stability. An optional 0.1µF ceramic capacitor can be added at the OUT pin to improve transient response during large load steps, but omission saves board space and is fully supported per the datasheet. This applies strictly to MAX6064BEUR+T and all members of the MAX6061–MAX6068 family.
What is the load current capability of MAX6064BEUR+T?
MAX6064BEUR+T can source up to 5mA and sink up to 2mA while maintaining specified output voltage accuracy. Load regulation is characterized at 0.5–0.9 mV/mA for sourcing and 2.2–8 mV/mA for sinking. This dual-direction capability allows MAX6064BEUR+T to drive reference inputs, bias networks, and even small LED indicators without external active components.
How does the temperature coefficient of MAX6064BEUR+T affect system accuracy?
With a maximum temperature coefficient of 20ppm/°C, MAX6064BEUR+T contributes ≤1.7mV of output drift over the full −40°C to +85°C range (125°C span). For a 4.096V reference, that equals ±0.042% full-scale error - well within the 0.1% total error budget of most 12-bit measurement systems. This makes MAX6064BEUR+T suitable for uncalibrated industrial sensors and portable test equipment.
Is MAX6064BEUR+T pin-compatible with other devices in the MAX6061–MAX6068 family?
Yes, all MAX6061–MAX6068 variants, including MAX6064BEUR+T, share identical 3-pin SOT23-3 pinout (IN, OUT, GND) and mechanical footprint. This allows drop-in replacement across output voltages (1.25V to 5.0V) without PCB layout changes - provided input voltage and load requirements remain compatible. The top-mark codes differ (e.g., FZGC for MAX6064BEUR+T), but physical pin mapping is identical.
