Overview
The AD584LH, produced by Analog Devices Inc., is a precision voltage reference integrated circuit. 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 notable for its high precision and flexibility, making it suitable for a variety of applications requiring accurate voltage references.
The AD584LH utilizes laser wafer trimming (LWT) to adjust the output levels and temperature coefficients, ensuring high accuracy and low temperature drift. 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.
