MAX6037CAUK21

Overview

The MAX6037CAUK21 is a low-power, fixed-output series voltage reference from the Maxim Integrated portfolio, now part of Analog Devices. It provides a stable 2.048 V output with an initial accuracy of 0.5% and a temperature coefficient of 6 ppm/°C. The device operates within an input voltage range up to 6 V and supports a maximum shunt current of 5 mA. It functions reliably across an extended industrial temperature range from -40°C to +125°C. Packaged in a compact SOT-23-5 surface-mount format, it is designed for applications requiring precise voltage regulation with minimal power consumption.

Feature Summary

• Provides a fixed 2.048 V output with high initial accuracy
• Features low temperature drift for stable performance across varying thermal conditions
• Supports shutdown functionality to minimize power consumption during idle periods
• Utilizes a compact SOT-23-5 package suitable for space-constrained designs

Applications

• Portable battery-powered instrumentation
• Data acquisition systems requiring precise analog references
• Industrial process control loops
• Medical equipment signal conditioning

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or official ADI channels. Confirm RoHS compliance status and check for recent lifecycle notices, as some Maxim Integrated products may be subject to discontinuation or limited availability. Ensure the specific suffix matches the required output voltage and accuracy grade before procurement.

Selection Notes

Select this component when a fixed 2.048 V reference is required with moderate accuracy (0.5%) and low quiescent current. Consider the SOT-23-5 package constraints for PCB layout. Compare against higher precision variants if tighter tolerance or lower noise is needed, or against adjustable versions if flexible output scaling is necessary for the specific circuit topology.

Part Context

This part belongs to the MAX6037 family of low-power voltage references. The 'C' suffix typically denotes a specific accuracy grade (0.5%), while 'UK' indicates the SOT-23-5 package type. The '21' specifies the 2.048 V output voltage. This family integrates into broader power management solutions for embedded systems, bridging legacy Maxim Integrated offerings with current Analog Devices portfolios.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6037 series offering different voltage outputs or accuracy grades. Verify if newer Analog Devices voltage references provide improved specifications such as lower noise or higher accuracy while maintaining the same footprint and electrical characteristics.
