AD587KRZ-REEL

Voltage Reference Overview

The AD587KRZ-REEL is a high precision monolithic voltage reference providing a fixed 10.000 V output with an initial accuracy of ±5 mV and a maximum temperature coefficient of 10 ppm/°C. It operates within a specified temperature range of 0°C to 70°C, drawing a maximum quiescent current of 4 mA from an input supply between 13.5 V and 36 V. The device features low output noise of 4 μV p-p (0.1 Hz to 10 Hz) and supports up to 10 mA sourcing or sinking load current. Packaged in an 8-lead SOIC for surface-mount applications, it includes dedicated pins for fine trimming and external noise reduction.

Voltage Reference Feature Summary

• Laser trimmed for high initial accuracy and low temperature drift without requiring external components.
• Utilizes a buried Zener diode design to achieve lower noise and drift compared to standard band gap references.
• Includes a dedicated noise reduction pin that allows further filtering using an external capacitor.
• Offers an optional fine trim connection for precise calibration of the output voltage level.

Voltage Reference Applications

• Precision reference for 8-bit, 10-bit, 12-bit, 14-bit, or 16-bit multiplying CMOS DACs
• Reference source for successive approximation or integrating ADCs with up to 14 bits of accuracy
• High precision current source configurations

Voltage Reference Procurement Notes

Verify the specific grade suffix against the ordering guide to confirm performance parameters. The 'K' designation indicates a 5 mV initial error and 10 ppm/°C temperature coefficient. Ensure the 'REEL' suffix matches the required tape and reel quantity for the manufacturing process. Confirm RoHS compliance status if environmental regulations apply to the assembly line.

Voltage Reference Selection Notes

Select this component when a stable 10 V reference is required for systems utilizing industry-standard pinouts. The AD587KRZ-REEL is suitable for upgrading existing designs due to its compatibility with legacy packages. Consider the K grade for general industrial applications operating between 0°C and 70°C where moderate precision is sufficient.

Voltage Reference Part Context

The AD587 series represents a class of high precision voltage references based on ion-implanted buried Zener technology. This family includes various grades such as J, K, and U, which differ in accuracy and temperature range specifications. The KRZ variant specifically denotes the K-grade performance level housed in a lead-free, surface-mount SOIC package compliant with modern manufacturing standards.

Voltage Reference Replacement Considerations

Direct replacements include other AD587 variants with different packaging or grades, such as AD587KR or AD587JRZ. For upgraded performance, the AD587U offers wider temperature ranges and tighter coefficients. Verify pinout compatibility before substituting with non-Analog Devices parts.
