AD587JR
The AD587JR is a precision three-terminal programmable voltage reference from Analog Devices. It uses a combination of two precision integrated circuit (IC)s, in one package, to provide a programmable voltage reference with improved accuracy and transient performance. This reference features a high input impedance and low output impedance. It is ideal for providing a very low output drift as it can be programmed over a wide range of currents.

The AD587JR is a programmable voltage reference IC. It has three terminals; a non-inverting or output terminal, an inverting or reference terminal, and a programming terminal. The programming terminal can be adjusted to control the output voltage of the reference. The main differences between this device and comparable voltage references are the integrated circuitry and the ability to program a wide range of currents. The integrated circuitry provides increased accuracy, improved transient performance, and lower output impedance.

The AD587JR’s primary application field is in precision analog-to-digital (A/D) conversion, industrial process control and automotive monitoring systems. It is also used in digital-to-analog (D/A) conversion, portable instrumentation, and as a power supply monitor. By providing a stable and accurate reference, the AD587JR enables various circuitry to accurately measure or convert signals.

The AD587JR’s primary working principle involves employed proprietary circuitry to minimize temperature drift, voltage and current noise, and thermal effects. It also selectively amplifies the ground reference and adjusts the output impedance to reduce impedance effects. This allows the output of the voltage reference to remain stable despite the changing electrical environment.

The AD587JR is designed to provide excellent performance and precision throughout the specified temperature range of −40°C to +125°C. It is designed for applications that require a low-cost and proven three-terminal programmable voltage reference with precision performance and extended temperature ranges. This IC has a wide range of current ratings from 1.5 mA to 25mA. The output voltage range can also be programmed with an external resistor divider to output any voltage between 0V and 6.2V.

In summary, the AD587JR is a three-terminal programmable voltage reference IC from Analog Devices. It is designed to use proprietary circuitry to minimize temperature drift, voltage and current noise, and thermal effects. This IC is primarily used in precision analog-to-digital (A/D) conversion, industrial process control and automotive monitoring systems. The AD587JR has a wide range of current ratings from 1.5 mA to 25mA, with an output voltage range that can be programmed with an external resistor divider to output any voltage between 0V and 6.2V. It is designed for applications that require a low-cost and proven three-terminal programmable voltage reference with precision performance and extended temperature ranges.
