Overview
The AD584JNZ, produced by Analog Devices Inc., is an 8-terminal precision voltage reference. It offers pin programmable selection of four popular output voltages: 10.000 V, 7.500 V, 5.000 V, and 2.500 V. This device is highly flexible, allowing for other output voltages to be achieved by adding external resistors. The AD584JNZ utilizes laser wafer trimming (LWT) to adjust the output levels and temperature coefficients, ensuring high precision and low errors over temperature. It also features a unique strobe terminal that allows the device to be turned on or off with a single, low power signal, reducing the current drain to approximately 100 μA in the off state and consuming typically 750 μA in the on state, including the output buffer amplifier.
