MAX6104EUR-T

Overview

The MAX6104EUR-T is a low-cost, micropower, low-dropout voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 2.5V with an initial accuracy of ±0.4% maximum and a temperature coefficient of 75ppm/°C maximum. The device operates over an extended temperature range from -40°C to +85°C and features a quiescent supply current of 125µA maximum. It utilizes a proprietary curvature-correction circuit and laser-trimmed thin-film resistors for stability. The component is housed in an ultra-small 3-pin SOT23 package and does not require an output capacitor.

• Digital Multimeters (DMMs)

Procurement Notes

Verify the specific suffix 'EUR-T' against official manufacturer documentation to confirm tape-and-reel packaging and European compliance status. Ensure the source document explicitly lists this part number variant. Cross-reference the manufacturer designation to confirm it is attributed to Analog Devices or Maxim Integrated as stated. Confirm the operating temperature range matches the specified -40°C to +85°C limits for your application environment.

Selection Notes

Select this component when a fixed 2.5V reference is required in space-constrained designs utilizing the SOT23 package. It is suitable for applications demanding micropower consumption and high accuracy without external compensation components. Consider the 75ppm/°C temperature coefficient for thermal stability requirements. Verify that the 125µA quiescent current aligns with the system's power budget constraints.

Part Context

This component belongs to the MAX6100–MAX6107 family of low-dropout voltage references. These devices share common architectural features including micropower operation and the absence of required output capacitors. The family offers various fixed output voltage options, with the MAX6104 specifically providing a 2.5V output. They are designed for general-purpose precision applications requiring small form factors.

Replacement Considerations

Consult official manufacturer substitution guides for verified equivalents within the MAX610x series or other compatible low-dropout voltage references. Do not assume functional interchangeability based on pinout alone; verify electrical parameters such as dropout voltage and load regulation.
