MAX874CSA

Overview

The MAX874CSA is a three-terminal voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 4.096V with an initial accuracy of ±0.38%. The device operates within a supply voltage range of 2.5V to 40V and delivers a maximum output current of 10mA. It is housed in an 8-pin Plastic Dual In-Line Package (PDIP) suitable for through-hole mounting. The component functions effectively across a temperature range of 0°C to +70°C, ensuring stable reference performance for precision analog circuits.

Feature Summary

• Provides a precise 4.096V fixed output voltage with high initial accuracy
• Operates over a wide input supply voltage range up to 40V
• Capable of sourcing up to 10mA of load current
• Designed for stability in precision analog signal processing applications

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Digital-to-analog converter (DAC) voltage references
• High-accuracy measurement instrumentation systems
• Calibration equipment requiring stable voltage standards

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for 8-pin DIP configurations. Confirm that the required output current does not exceed the specified 10mA limit under all operating conditions. Check for updated lifecycle status as older Maxim Integrated components may have limited availability or obsolescence notices.

Selection Notes

Select this component when a stable 4.096V reference is required for single-supply systems. Consider the ±0.38% initial accuracy for applications demanding tight tolerance without external trimming. Evaluate the 10mA output capability against the total system load to ensure adequate drive strength. Verify that the 0°C to +70°C industrial temperature range meets the environmental requirements of the target application.

Part Context

This part belongs to the MAX874 series of low-power, high-precision voltage references from Maxim Integrated. The series offers various output voltages and accuracy grades to support diverse data acquisition needs. The CSA variant specifically denotes the plastic DIP packaging option, distinguishing it from surface-mount equivalents like the MAX874CSE. These devices are commonly used in industrial control and test equipment where reliable voltage referencing is critical.

Replacement Considerations

Consult official cross-reference guides for direct pin-compatible alternatives such as other MAX874 variants with different output voltages or accuracies. Verify thermal performance and package dimensions when substituting with similar three-terminal references from other manufacturers.
