MAX6520EUR

Overview

The MAX6520EUR is a low-power, precision, three-terminal series voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 1.2V with an initial accuracy of ±1%. The device operates within an input voltage range of 2V to 3.6V and draws a maximum supply current of 40µA. It features a temperature coefficient of 50ppm/°C and supports a maximum shunt current of 400µA. The component functions reliably across an operating temperature range of -40°C to +85°C and is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

• Provides a stable 1.2V fixed output voltage suitable for precision applications
• Ultra-low power consumption with 40µA supply current for battery-operated systems
• Compact SOT-23-3 surface-mount package design for space-constrained layouts

Applications

• Battery-powered portable equipment
• Industrial control systems
• Automotive electronics
• Handheld instruments

Procurement Notes

Verify the specific suffix (e.g., EUR) against the manufacturer's official datasheet to confirm pinout, tolerance grade, and packaging configuration. Ensure compatibility with your system's input voltage range and thermal requirements. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a low-cost, low-power voltage reference is needed for 3V battery-powered applications. It is suitable for designs requiring a fixed 1.2V reference with moderate precision (±1%) and a 50ppm/°C temperature coefficient. Consider the SOT-23-3 package size for PCB real estate constraints. Evaluate if the 400µA shunt current capability meets the load requirements of your downstream circuitry.

Part Context

The MAX6520 belongs to the Maxim Integrated voltage reference family, designed for low-power applications. It serves as a cost-effective alternative to higher-precision references while maintaining stability in portable devices. The series offers various output voltages and packages, but the MAX6520 specifically targets the 1.2V niche for battery-operated systems where power efficiency is critical.
