REF02AP

Overview

The REF02AP is a fixed precision voltage reference from Texas Instruments, delivering a nominal output of 5 V. It features an initial accuracy of ±0.2% and operates within a temperature range of -40°C to +85°C. The device utilizes a series topology with a maximum input voltage of 40 V. It is housed in an 8-pin PDIP package for through-hole mounting. Key electrical characteristics include a line regulation of 0.01%/V and load regulation of 0.01%/mA.

Feature Summary

• Provides stable 5 V reference via series topology
• Ensures high precision with ±0.2% initial accuracy
• Supports wide input voltage up to 40 V
• Designed for through-hole PCB integration

Applications

• Precision analog-to-digital converter (ADC) references
• Digital-to-analog converter (DAC) excitation sources
• Calibration equipment requiring stable voltage standards
• Instrumentation signal conditioning circuits

Procurement Notes

Verify the specific suffix 'P' confirms the PDIP package variant when sourcing. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as environmental declarations may vary by production batch. Ensure the ordering part number matches the required through-hole configuration for your design.

Selection Notes

Select this component when a through-hole 5 V reference with ±0.2% accuracy is required. It suits designs needing robust performance over a -40°C to +85°C range. Consider the 40 V maximum input voltage for flexible supply configurations. Verify that the 8-pin DIP footprint aligns with your board layout constraints.

Part Context

The REF02AP belongs to the REF02 family of precision voltage references manufactured by Texas Instruments. This series is designed for applications demanding high stability and low noise. The 'AP' designation specifically identifies the through-hole PDIP package version, distinguishing it from surface-mount variants like the SOIC-8 packages found in other REF02 models.
