AD587KNZ is a monolithic Precision Voltage Reference from Analog Devices. It is designed to provide a stable, low noise DC voltage reference for applications requiring precision voltage reference. AD587KNZ is one of the top products in Analog Devices’ precision voltage reference family. It is widely applied in high precision circuits where voltage stability and accuracy are critical, especially in instrumentation and industrial control applications.

The AD587KNZ is a low noise, high precision precision voltage reference that is fully temperature compensated over 0 to +70°C. Its precision is due to a patented design that uses a combination of laser trimming and a laser trimmed negative temperature coefficient resistor to linearize the reference output. This configuration results in relatively low noise, high linearity and drift-free reference voltage performance.

The AD587KNZ contains an on-chip buffer amplifier that allows it to output both AC and DC signals with minimal loading. It is also capable of providing up to 10mA of output current when used in certain configurations. The AD587KNZ has an operating voltage range from 6V to 30V, a reference voltage range from 0.5V to 4.096V, and a buffer voltage range from 0.2V to 4.0V.

The construction of the AD587KNZ is based on a very high-speed, temperature-stable, precision, monolithic voltage reference that is designed to provide a low noise, high accuracy, and highly stable reference voltage. The reference voltage is generated by a precision resistor network that is integrated with on-chip trim resistors to precisely control the reference voltage and temperature coefficient. This ensures that the reference voltage remains stable and accurate over the entire operating temperature range.

The AD587KNZ is rated to provide a temperature coefficient of 0.001 %/°C, a voltage coefficient of 0.001 %/V and a drift rate of 0.5 μV/V. Additionally, it features a low temperature coefficient of 0.2%/V and a high accuracy of 0.001%. These characteristics combine to make the AD587KNZ one of the most stable references available.

The AD587KNZ is extremely reliable due to its robust design and extensive validation. It has a MTTF (Mean Time To Failure) of 10 million hours, which is among the highest in the industry. It also has a wide common-mode range, allowing it to withstand harsh environmental conditions, such as high temperature, shock and vibration.

The AD587KNZ is commonly used in precision voltage reference applications such as power control, precision measurement systems, high accuracy instrumentation and industrial control systems. It can also be used in medical and industrial applications where a stable, low noise and low drift voltage reference is required. The reference voltage generated by the AD587KNZ can also be used for the calibration of high accuracy ADCs.

The AD587KNZ is a highly reliable, low noise, high accuracy, and temperature-stable voltage reference for precision systems. Its design incorporates a combination of laser trimming and a laser trimmed negative temperature coefficient resistor to linearize the reference output. Its wide operating temperature range, low drift rate, and high accuracy provide a very stable voltage reference for precision applications.
