REF02CSA+T

Overview

The REF02CSA+T is a precision series voltage reference integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It provides a fixed output voltage of 20V with a tolerance of ±1%. The device operates within an input voltage range of 13V to 30V and delivers an output current of 21 mA. It features a low noise specification of 25µVp-p from 0.1Hz to 10Hz and a temperature coefficient of 65ppm/°C. The component is housed in an 8-SOIC surface-mount package and is designed for operation over a commercial temperature range of 0°C to +70°C.

Feature Summary

• Provides a stable, fixed 20V output with high accuracy.
• Features low noise performance suitable for sensitive analog circuits.
• Operates with a wide input voltage range up to 30V.

Applications

• Precision data acquisition systems
• High-resolution analog-to-digital converter references
• Calibration equipment requiring stable voltage sources

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates. Ensure the 8-SOIC footprint matches the target PCB layout. Check for obsolescence notices as Maxim products may transition to Analog Devices inventory systems.

Selection Notes

Select this component when a fixed 20V reference is required rather than adjustable options. Compare against the REF01CSA+T if a 10V output is sufficient, as it shares similar electrical characteristics. Consider the REF50xx series for lower noise applications if the 25µVp-p specification is insufficient. Verify that the 21mA output current meets the load requirements of the downstream circuitry.

Part Context

This part belongs to the Maxim REF01/REF02 family of high-precision voltage references. These devices are designed to replace older zener-based references with superior stability and lower noise. The REF02 variant specifically targets applications needing a 20V rail, complementing the 10V REF01 and other industry-standard reference voltages.
