REF02BP

Overview

The REF02BP is a precision voltage reference from the REF02 series, manufactured by Texas Instruments. It provides a fixed 5 V output with an initial accuracy of ±0.2%. The device operates within a wide supply range up to 40 V and supports a maximum shunt current of 8 mA. It features a temperature coefficient of 15 PPM/°C and draws a typical operating supply current of 1 mA. The component is housed in an 8-pin PDIP package and functions reliably across an extended industrial temperature range from -40°C to +85°C.

Feature Summary

• Delivers high-precision 5 V reference output with tight initial accuracy tolerance
• Operates over a wide input supply voltage range up to 40 V
• Maintains stable performance across extended industrial temperature conditions

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Digital-to-analog converter (DAC) voltage references
• High-resolution measurement instrumentation systems

Procurement Notes

Verify the specific suffix 'BP' against official Texas Instruments documentation to confirm package type and compliance status. Ensure the ordering part number matches the required lead-free or RoHS specifications. Cross-reference the manufacturer datasheet for any recent product change notices that may affect pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a stable 5 V reference is required for precision data acquisition circuits. Consider the ±0.2% initial accuracy and 15 PPM/°C temperature coefficient for applications demanding high stability. Verify that the 8 mA shunt current capability meets the load requirements of the connected circuitry.

Part Context

The REF02 series represents a family of monolithic precision voltage references designed for demanding analog applications. These devices integrate bandgap reference circuitry to provide low noise and high long-term stability. The REF02BP variant specifically utilizes an 8-pin DIP package, catering to through-hole mounting requirements in industrial and test equipment designs.

Replacement Considerations

Consult official substitution guides for compatible alternatives such as the REF02BU or REF02AU if package changes are acceptable. Verify electrical parameter equivalence before replacing components in existing designs.
