AD584KH is a voltage reference device that is categorized as PMIC—Voltage Reference. Voltage references, which are also known as reference voltages or shunt references, are precision semiconductor devices that produce a stable, reproducible DC output voltage despite large changes in load current and environmental temperature. An accurate voltage reference will remain constant over varying temperatures and aging periods.

Analog Devices' AD584KH is a monolithic, shunt-mode reference voltage integrated circuit (IC). This device is unique in that it offers a high precision buffered output, low reference impedance, low dynamic impedance, and a fast settling time—making it ideal for use in high performance data acquisition systems. It also provides excellent stability over temperature and time.

The AD584KH is a family of voltage references that offer several types of voltage reference options. For example, the AD584KH-7V and the AD584KH-15V provide seven- and fifteen-volt outputs, respectively. For those applications requiring higher voltage references, the AD584KH-30V and the AD584KH-60V provide a 30- and 60-volt output. An optional reference trim is available on all of the mentioned devices, allowing for tight initial accuracy tolerances and excellent temperature stability.

The AD584KH device is an integrated voltage reference, with an output buffer capable of delivering up to 30mA, and a low reference output impedance—measured at 2 ohms. It features low-frequency drift, excellent temperature stability, and a wide operating range—from 1.8V to 44V. This device also has a low-level output noise and fast settling time.

One of the most notable features of the AD584KH is its special temperature adjustment procedure. This procedure requires three simple steps: (1) Adjust the reference adjust potentiometer for the desired reference voltage; (2) Connect the adjust output to a temperature sensor; and (3) Spend a few minutes adjusting the voltage reference as the temperature sensor changes. This temperature adjustment procedure allows for excellent initial accuracy and superior long-term stability, making it ideal for high-performance data acquisition systems.

The AD584KH can fulfil a multitude of uses across a variety of applications. Its low-noise, high-impedance, and fast-settling characteristics are perfect for precision instrumentation, digital-to-analog converters, and A/D converters design. It is also suitable for reference voltage trimming, voltage monitor circuits, zero-calibration and operational circuit powering. From home entertainment systems to laboratory test and measurement equipment, the AD584KH provides the reliability and accuracy necessary for a variety of applications.

In conclusion, AD584KH is a PMIC—Voltage Reference device that features high precision buffered output and excellent temperature stability. This device is designed to meet the requirements of high performance data acquisition systems. It also has a low reference output impedance and fast settling time, making it suitable for precision instrumentation and a variety of other applications. With its easy temperature adjustment procedure, excellent initial accuracy and superior temperature stability, the AD584KH is an ideal choice for applications requiring unsurpassed long-term stability.
