Overview
The MAX6018AEUR21+T is a precision, low-voltage, micropower voltage reference in a SOT23-3 package. It provides a fixed output of 2.048V with an initial accuracy of ±0.2%. The device operates from an input voltage range of 2.25V to 5.5V and consumes a maximum quiescent supply current of 6µA across the -40°C to +85°C temperature range. It features a maximum temperature drift of 50ppm/°C and can source up to 1mA of load current.
Feature Summary
- Ultra-low supply current consumption independent of supply voltage
- High initial accuracy of ±0.2% for precision applications
- Capable of sourcing and sinking up to 1mA of load current
- Operates with a minimum dropout voltage of 200mV
Applications
- Two-cell battery-operated systems
- Battery-monitoring equipment
- Data-acquisition systems
- Industrial process-control systems
Procurement Notes
Verify the specific suffix 'EUR21' corresponds to the 2.048V output option and 'A' grade for ±0.2% accuracy. Confirm the '+T' designation indicates tape-and-reel packaging. Ensure compatibility with the required 2.25V minimum input voltage for this specific output variant.
Selection Notes
Select this component when a stable 2.048V reference is required in space-constrained designs. The A-grade accuracy is suitable for high-precision measurement circuits. Consider the 6µA maximum current draw for strict power budget constraints in portable devices.
Part Context
This part belongs to the MAX6018 family of bandgap voltage references manufactured by Analog Devices (Maxim Integrated). The family includes variants with different output voltages (1.2V, 1.6V, 1.8V) and accuracy grades (A and B), all sharing the same compact SOT23-3 footprint and low-power architecture.
Replacement Considerations
MAX6018BEUR21+T offers the same 2.048V output but with lower ±0.4% accuracy.
FAQ
What is the minimum input voltage required for the MAX6018AEUR21+T?
The minimum input voltage is 2.25V, which ensures proper operation given the 2.048V output and 200mV dropout voltage.
Does the MAX6018AEUR21+T require an external resistor?
No, unlike conventional shunt-mode references, the MAX6018 does not require an external resistor to function.
