AD587JRZ-REEL7

Voltage Reference Overview

The AD587JRZ-REEL7 is a high precision monolithic voltage reference providing a nominal 10.000 V output with an initial accuracy of ±10 mV and a maximum temperature coefficient of 20 ppm/°C. It operates within a specified temperature range of 0°C to +70°C, drawing a maximum quiescent current of 4 mA from a supply voltage up to 36 V. The device features a buried Zener diode architecture for low noise performance and includes dedicated pins for fine trimming and external noise reduction filtering.

Voltage Reference Feature Summary

• Laser trimmed for high initial accuracy and low temperature drift without requiring external components.
• Utilizes a proprietary ion-implanted buried Zener diode design for superior noise and stability compared to band gap references.
• Includes a dedicated noise reduction pin allowing further attenuation of output noise via 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 DACs
• Reference source for successive approximation or integrating ADCs
• Multiplying CMOS DAC applications

Voltage Reference Procurement Notes

Verify the specific grade suffix (J) against project requirements to ensure the correct initial accuracy and temperature coefficient specifications are met. Confirm that the SOIC package option aligns with the PCB footprint and assembly capabilities. Ensure the operating environment remains within the 0°C to +70°C specified range for guaranteed performance parameters.

Voltage Reference Selection Notes

Select this component when a stable 10 V reference is required for medium-to-high resolution data conversion systems. The J grade offers a balance of cost and performance suitable for commercial applications. Consider the U grade if extended temperature operation is necessary, or utilize the fine trim pin if system-level calibration demands tighter voltage tolerance than the factory specification provides.

Voltage Reference Part Context

This part belongs to the AD587 family of high precision voltage references manufactured by Analog Devices. The family utilizes a buried Zener technology to achieve low noise and drift characteristics. The JRZ-REEL7 designation indicates the J grade version packaged in an 8-lead SOIC format and supplied in a reel configuration for surface-mount assembly processes.

Voltage Reference FAQ

How can the output noise of the AD587 be reduced?

An external capacitor can be connected between the Noise Reduction pin (Pin 8) and ground to form a low-pass filter, which reduces the broadband noise generated by the internal Zener diode.

Is it possible to generate a negative reference voltage using this device?

Yes, the AD587 can be configured to provide a -10 V output by grounding the VOUT pin and connecting the GND pin through a resistor to a negative supply rail.
