REF01CS

Overview

The REF01CS is a precision series voltage reference providing a fixed 10.0 V output with an initial accuracy of ±0.3% maximum and a temperature coefficient of 8.5 ppm/°C maximum. It operates within a supply voltage range of 12 V to 36 V, drawing a quiescent current of 1.4 mA maximum. The device features a low noise profile of 30 µV p-p (0.1 Hz to 10 Hz) and supports a load current sourcing capability of 10 mA. Packaged in an 8-lead SOIC format, it includes a dedicated TRIM terminal for fine adjustment and a TEMP pin for temperature monitoring.

Feature Summary

• Provides high output accuracy with minimal change in response to variations in supply voltage, ambient temperature, or load conditions.
• Includes a dedicated TRIM terminal allowing for fine adjustment of the output voltage via an external resistor network.
• Features a TEMP pin that outputs a band gap voltage varying linearly with temperature for approximate sensing applications.

Applications

• Precision data systems
• High resolution converters
• Industrial process control systems

Procurement Notes

Verify the specific suffix 'S' confirms the 8-lead SOIC package configuration. Confirm the grade designation matches the required accuracy and temperature coefficient specifications. Ensure the operating environment falls within the specified commercial temperature range. Check for RoHS compliance status if required by the manufacturing process. Validate pinout compatibility against the target PCB footprint.

Selection Notes

Select this component when a stable 10 V reference is required in a surface-mount design. Consider the 8.5 ppm/°C stability for applications sensitive to thermal drift. Evaluate the 1.4 mA supply current against power budget constraints. Verify that the 10 mA load driving capability meets the downstream circuit requirements without additional buffering.

Part Context

The REF01CS belongs to the REF01/REF02/REF03 series of precision voltage references manufactured by Analog Devices. This family offers standard band gap reference voltages of 10.0 V, 5.0 V, and 2.5 V respectively. The series is designed for general-purpose use in both standard and high-stress applications, available in multiple package types including PDIP, CERDIP, and TO-99.

Replacement Considerations

Direct replacements include REF01CPZ and REF01EN8#PBF from Analog Devices. These alternatives maintain pin-for-pin compatibility while offering similar electrical characteristics. Newer designs may consider the ADR01 series for higher accuracy and wider temperature ranges.
