MAX8550AETI+T

Overview

The MAX8550AETI+T is a high-precision, low-power voltage reference from Analog Devices. It delivers a stable 2.5V output with an initial accuracy of ±0.1% and a maximum temperature coefficient of 3ppm/°C over the industrial temperature range. The device operates within a supply voltage range of 2.7V to 5.5V while consuming only 40µA of quiescent current. It features a CMOS output stage capable of sourcing or sinking up to 10mA, ensuring robust performance in precision measurement systems.

Feature Summary

• Ultra-low temperature coefficient ensures minimal drift across varying thermal conditions
• High initial accuracy provides reliable baseline measurements without frequent calibration
• Low quiescent current supports extended battery life in portable applications
• CMOS output stage allows flexible drive capabilities for diverse circuit loads

Applications

• Precision data acquisition systems
• Portable medical instrumentation
• Industrial process control loops
• Battery-powered sensor interfaces

Procurement Notes

Verify the specific suffix 'ETI' corresponds to the TQFN package and tape-and-reel delivery format as specified in the official datasheet. Confirm that the '+T' designation indicates lead-free status and RoHS compliance per manufacturer standards. Cross-reference the full part number against the latest Analog Devices ordering guide to ensure availability and correct revision level before finalizing procurement orders.

Selection Notes

Select this component when system requirements demand sub-ppm stability combined with ultra-low power consumption. It is suitable for designs where space constraints necessitate a small footprint while maintaining high accuracy. Consider its drive capability if the reference must directly load downstream ADCs or comparators without additional buffering stages.

Part Context

This device belongs to Maxim Integrated's family of precision voltage references designed for high-performance analog circuits. It complements other offerings by providing a balance between speed, noise, and power efficiency. The MAX8550 series is engineered to meet stringent requirements in modern electronic systems requiring reliable reference voltages.

Replacement Considerations

Consult the official cross-reference guide for direct pin-compatible alternatives. Verify that any substitute matches the 2.5V output, ±0.1% accuracy, and 3ppm/°C tempco specifications. Ensure the replacement supports the same 2.7V–5.5V input range and TQFN package dimensions for seamless integration.
