MAX675CSA+

Overview

The MAX675CSA+ is a precision voltage reference manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-pin Narrow SO package. It provides a pretrimmed +5V output with an initial tolerance of ±7mV and a temperature coefficient of 12ppm/°C. The device operates within a supply voltage range of 10V to 33V, drawing a maximum quiescent current of 1400µA. It features short-circuit protection, low noise (10µVP-P), and a dedicated TEMP pin for temperature sensing.

Feature Summary

• Pretrimmed to +5V with excellent temperature stability
• Includes a dedicated temperature-dependent voltage output on the TEMP pin
• Features short-circuit protection and adjustable output via the TRIM terminal

Applications

• A/D Converters
• D/A Converters
• Digital Voltmeters
• Voltage Regulators
• Threshold Detectors

Procurement Notes

Verify the specific suffix 'CSA' corresponds to the 8-pin Narrow SO package and the 0°C to +70°C operating temperature range. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the ordering information matches the exact grade and package type needed for your design specifications.

Selection Notes

Select this component when a stable +5V reference is required with minimal drift over temperature. The narrow SO package offers space-saving benefits for compact designs. Consider the available trim adjustment if system errors require calibration beyond the factory-set tolerance. Evaluate the TEMP pin utility if integrated temperature monitoring is beneficial.

Part Context

This part belongs to the MAX675 family of precision voltage references from Maxim Integrated. The family includes various packages such as PDIP, CERDIP, and TO-99, along with different temperature grades like MAX675E and MAX675M. The MAX675CSA+ specifically denotes the commercial grade version in the surface-mount Narrow SOIC format.

Replacement Considerations

The datasheet notes pin-for-pin compatibility with the REF02. Verify electrical parameters against potential alternatives to ensure performance requirements are met.

FAQ

What is the function of the TEMP pin?

The TEMP pin provides a temperature-dependent output voltage proportional to absolute temperature, with a scale factor of approximately 2.1mV/°C.

Can the output voltage be adjusted?

Yes, the TRIM terminal allows adjustment of the output voltage over a 5V ±150mV range to compensate for system errors.
