Laser wafer trimming (LWT) is used to adjust the pin programmable output levels and temperature coefficients, resulting in the most flexible high precision voltage reference available in monolithic form.
In addition to the programmable output voltages, the AD584JNZ offers a unique strobe terminal that permits the device to be turned on or off. When the AD584JNZ is used as a power supply reference, the supply can be switched off with a single, low power signal. In the off state, the current drained by the AD584JNZ is reduced to approximately 100 μA. In the on state, the total supply current is typically 750 μA, including the output buffer amplifier.
The AD584JNZ is recommended for use as a reference for 8-, 10-, or 12-bit digital-to-analog converters (DACs) that require an external precision reference. In addition, the device is ideal for analog-to-digital converters (ADCs) of up to 14-bit accuracy, either successive approximation or integrating designs, and in general, it can offer better performance than that provided by standard self-contained references.
The AD584J and AD584K are specified for operation from 0°C to +70°C, and the AD584S and AD584T are specified for the −55°C to +125°C range. All grades are packaged in a hermetically sealed, eight-terminal TO-99 metal can, and the AD584J and AD584K are also available in an 8-lead PDIP.
