MAX6045BEUR

Overview

The MAX6045BEUR is a precision, low-power series voltage reference IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It provides a fixed output voltage of 4.5V with an initial accuracy of ±0.4%. The device operates within an input voltage range of 2.7V to 36V and draws a maximum supply current of 18µA. It features a temperature coefficient of 50ppm/°C and is housed in a compact SOT-23-3 surface-mount package. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides a stable 4.5V reference output with high initial accuracy
• Designed for low-power applications with minimal quiescent current consumption
• Operates over a wide input voltage range suitable for various supply conditions
• Compact three-terminal SOT-23 package facilitates space-constrained designs

Applications

• Portable instrumentation requiring precise voltage references
• Battery-powered measurement systems

• Handheld meters

Procurement Notes

Verify the specific suffix and tape-and-reel specifications when ordering, as packaging variations may exist. Confirm RoHS compliance status for the exact batch. Check lead times and availability directly with authorized distributors, as stock levels fluctuate. Ensure the selected variant matches the required output voltage and tolerance for your circuit design.

Selection Notes

Select this component when a stable 4.5V reference is needed in a small footprint. Compare against other MAX60xx series variants if different output voltages or tighter tolerances are required. Consider the 50ppm/°C temperature coefficient for thermal stability requirements. Verify that the 18µA supply current fits the power budget of the target application.

Part Context

This part belongs to the MAX60xx family of micropower voltage references from Maxim Integrated. These devices are designed to offer high precision and low power consumption in small packages. The MAX6045 specifically targets applications needing a 4.5V rail, complementing other outputs like 2.5V or 5.0V within the same product line.

Replacement Considerations

Direct substitutes include other MAX60xx series parts with compatible pinouts and similar electrical characteristics. Verify output voltage compatibility before substitution. Cross-reference with MAX6045BEUR+T for tape-and-reel versions.
