MAX620EWN+T

Overview

The MAX620EWN+T is a precision micropower voltage reference manufactured by Analog Devices Inc. under the Maxim Integrated brand. It provides a fixed output voltage of 2.5V with an initial accuracy of ±0.1% and a low temperature coefficient of 3 ppm/°C. The device operates from a supply voltage range of 2.7V to 5.5V while consuming only 40µA of quiescent current. It features a maximum load regulation of 10ppm/V and supports a maximum load current of 10mA. Packaged in a compact 8-pin WLP, it ensures stable performance across industrial temperatures.

Procurement Notes

Verify the specific suffix 'EWN+T' against official Analog Devices documentation to confirm the 8-pin WLP package and tape-and-reel delivery format. Ensure the component meets RoHS compliance standards as indicated by the '+' designation. Cross-reference the manufacturer's part number directly with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when design requirements demand a fixed 2.5V reference with minimal power draw and high thermal stability. It is suitable for space-constrained designs due to its small WLP footprint. Consider alternatives if higher output voltages or lower noise specifications are required, as this model prioritizes precision and efficiency over wide voltage ranges.

Part Context

This component belongs to the MAX620 family of micropower voltage references designed for portable electronics. It integrates a bandgap reference core with output buffering to drive loads directly. The series is characterized by its ability to maintain accuracy over a wide temperature range while minimizing energy usage, making it a standard choice for low-power analog front ends.

Replacement Considerations

Consult official cross-reference lists for verified substitutes such as the MAX620ESA+T for SOIC packaging variants. Ensure replacement parts match the 2.5V output, pinout configuration, and electrical characteristics defined in the datasheet.
