Product details
Overview
MAX6064BEUR+ from Maxim Integrated is a precision, micropower, low-dropout series voltage reference delivering a stable 4.096V output with ±0.4% 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 down to 4.296V input (VOUT + 200mV), making it ideal for high-resolution 12-bit ADC biasing in portable instrumentation.
For engineers reviewing the MAX6064BEUR+ datasheet, MAX6064BEUR+ pinout, MAX6064BEUR+ application, or MAX6064BEUR+ equivalent, key selection criteria include its guaranteed 4.096V output tolerance, ultra-low 90µA quiescent current, no-output-capacitor-required stability, 200mV max dropout at 1mA, and SOT23-3 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX6064BEUR+ is a three-terminal, series-mode voltage reference using proprietary curvature-correction circuitry and laser-trimmed thin-film resistors to achieve tight initial accuracy and low thermal drift. Its internal compensation eliminates need for external capacitors, unlike shunt-mode references requiring bias resistors and output stabilization networks.
It features supply-current independence (≤8µA/V variation) across 4.296V–12.6V input range, stable operation with capacitive loads, and robust transient response-settling to 0.1% of final value in 190µs with 50pF load capacitance-enabling use in dynamic, battery-powered measurement systems.
Key Specifications

|---|---|---|---|
| ADR3440BRJZ-R7 | 4.096V output, ±0.1% initial accuracy, 10ppm/°C tempco, 120µA quiescent current, SOT23-3 | Higher accuracy and lower drift, but 33% higher supply current limits battery life in ultra-low-power designs | Select when absolute precision outweighs current budget; verify layout compatibility with different top-mark and thermal pad. |
| REF3040AIDBZR | 4.096V output, ±0.2% initial accuracy, 50ppm/°C tempco, 50µA quiescent current, SOT23-3 | Lower quiescent current, but higher tempco degrades accuracy above 40°C ambient; no internal curvature correction | Prefer for sub-40°C environments where microamp savings justify reduced thermal stability; not recommended for outdoor instrumentation. |

FAQ
What is the maximum input voltage rating for MAX6064BEUR+?
The MAX6064BEUR+ has an absolute maximum input voltage of +13.5V referenced to GND. However, its specified operating input range is (VOUT + 0.2V) to +12.6V, i.e., 4.296V to 12.6V. Exceeding 13.5V risks permanent damage per the Absolute Maximum Ratings table in the MAX6061–MAX6068 datasheet. Always observe derating guidelines for reliability in continuous operation.
Does MAX6064BEUR+ require an output capacitor for stability?
No, MAX6064BEUR+ does not require an output capacitor for stability due to internal compensation. It remains stable with capacitive loads up to 1µF. An optional 0.1µF ceramic capacitor may be added at the OUT pin to improve transient response during large load steps, but omission saves board area and reduces BOM count-critical in SOT23-based portable designs.
How does the initial accuracy of MAX6064BEUR+ compare to the 'A' grade variant?
MAX6064BEUR+ has ±0.4% initial accuracy (max) at +25°C, while the 'A' grade MAX6064AEUR+ offers ±0.2%. Both share identical 20ppm/°C max temperature coefficient and 90µA typical quiescent current. Choose MAX6064BEUR+ when 0.4% tolerance satisfies system-level accuracy requirements-typically sufficient for 12-bit ADC applications-and cost optimization is prioritized.
Can MAX6064BEUR+ sink current, and what is the limit?
Yes, MAX6064BEUR+ can sink up to 2mA of load current, as confirmed in the General Description and Electrical Characteristics tables. This capability allows it to drive reference inputs requiring sinking current (e.g., certain DACs or op-amp configurations) and simplifies bidirectional biasing circuits without external components. Operation beyond 2mA may cause output voltage deviation exceeding specification limits.
What is the typical turn-on settling time for MAX6064BEUR+?
The MAX6064BEUR+ settles to within 0.1% of its final 4.096V output in 190µs with a 50pF load capacitance, as specified in the Electrical Characteristics table for MAX6064. This value increases with larger capacitive loads or operation near dropout; for example, with 1µF load and 2mA step, settling may extend to ~1.5ms. System timing budgets must account for this parameter in wake-up or measurement-trigger sequences.
