A new series of voltage references have been released by Analog Devices, Inc. (ADI) that mix noise performance, initial output voltage accuracy, low temperature coefficient (TC), and long-term stability, creating a well-rounded solution.
The new ADR45xx series of devices are well suited for high-resolution data converters and precision applications in data acquisition systems, instrumentation, process control, and automotive battery monitoring.
Adding to the list of effective measures, the devices feature a low frequency noise of 0.5 ppm, maximum temperature coefficient of 2 ppm/°C over a full operating temperature range that extends from -40 °C to 125 °C.
They also offer typical long-term drift of just 25 ppm/1khr, making the series of voltage references well equipped to provide high accuracy over time and temperature variations which is critical for many precision applications.
Such performance was enabled by a maximum quiescent current of 950 µA, and as the device is priced well within the market place, it makes them ideal for portable and budget sensitive applications.
