REF01CSA+

Overview

The REF01CSA+ is a precision series voltage reference providing a fixed 10V output. It operates on a single supply within an input voltage range of 13V to 30V and draws a quiescent current of 1.6mA. The device features a maximum temperature coefficient of 65ppm/°C and an initial accuracy tolerance of ±1%. It supports a load current up to 21mA and exhibits low noise characteristics with a peak-to-peak value of 25µV in the 0.1Hz to 10Hz bandwidth. The component is housed in an 8-SOIC package and functions reliably across a temperature range of 0°C to +70°C.

Feature Summary

• Provides a stable, factory-trimmed 10V output suitable for high-precision analog applications.
• Includes a trim terminal allowing for minor output voltage adjustments without significantly affecting temperature stability.
• Features short-circuit protection capable of indefinite duration when connected to ground or the input supply.

Applications

• Analog-to-Digital Converters
• Digital-to-Analog Converters
• Precision Calibration Standards

Procurement Notes

Verify that the specific part number matches the required operating temperature range and package type. Confirm that the input voltage supplied to the circuit remains within the specified 13V to 30V limits to ensure proper regulation. Ensure the design accounts for the maximum load current capability and thermal dissipation requirements associated with the SOIC package.

Selection Notes

Select this component when a fixed 10V reference is required for single-supply systems. Consider the 65ppm/°C temperature coefficient and ±1% initial accuracy against application requirements. Verify that the 1.6mA quiescent current draw aligns with power budget constraints. Ensure the 8-SOIC footprint fits the available board space.

Part Context

This device belongs to the REF01/REF02 family of industry-standard precision voltage references manufactured by Analog Devices Inc./Maxim Integrated. The REF01 variant specifically provides a 10V output, whereas the REF02 offers a 5V output with an additional temperature transducer pin. Both share similar architectural features and packaging options.
