Analog Devices Announces Voltage References for Precision Applications

April 29, 2012 by Jeff Shepard

Analog Devices, Inc. (ADI) introduced a series of voltage references offering what the company says is 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 new 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 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 950µA and $3.45 price, making the devices well suited for portable and budget sensitive designs. Also available is an A-grade version with a TC of 5 ppm/°C at $2.45.

The ADR45xx series of voltage references is well suited to operate with many of ADI’s low power, precision A/D converters such as the AD7685, AD7982 and AD7988-1/-5, as well as D/A converters, including the AD5780 and AD5764.
