The AD587JR-REEL7 is a precision voltage reference with exceptionally good drift and long-term stability characteristics that make it suitable for applications requiring stringent voltage accuracy. As a member of the analog products family, this Voltage Reference belongs to the PMIC (Power Management integrated circuit) category and is especially suited for applications that require the highest precision under severe environmental conditions such as high temperature.

The AD587JR-REEL7 integrates a 4cm2 highly accurate voltage reference, with an operating temperature range from -55 to + 125 °C. The AD587JR-REEL7 is a four-terminal device with two output pins, two input pins, and a ground pin. The two output pins provide a voltage reference output of 5.0000V ± 0.0025V. The input pins are used to provide a logic signal to the device to control the output reference voltage level.

The AD587JR-REEL7 has a bandgap reference topology for producing a voltage reference output with exceptional accuracy and stability. The bandgap reference is a temperature-compensated circuit that uses two transistors to bring the voltage level to a constant voltage. It works by as the temperature changes, the currents through the two transistors vary, and the bias of the output transistors keeps the output voltage constant.

As with other PMIC voltage references, the AD587JR-REEL7 is designed to provide power supply accuracy and stability in a variety of systems. Its low noise and high accuracy make it suitable for applications in communications, instrumentation and automotive markets where voltage stability and accuracy are essential.
