ADR45xx Voltage References

ADI presents a series of voltage references offering the industry’s best combination of noise performance, initial output voltage accuracy, low temperature coefficient (TC), and excellent long-term stability at unmatched price points. The ADR45xx series of voltage references are specifically suited for high-resolution data converters and precision applications in data acquisition systems, instrumentation, process control, and automotive battery monitoring.

With low frequency noise of 0.5 ppm, maximum temperature coefficient of 2 ppm/°C over the full operating temperature range of -40°C to +125°C, and a typical long-term drift of only 25 ppm/1khr, the ADR45xx series of voltage references provide high accuracy over time and temperature variations critical for many precision applications. This performance is achieved with a maximum quiescent current of 950 µA, making the devices ideal for portable and budget sensitive designs.
