ETL Testing
Data is of utmost importance in digital systems. Protecting data, therefore, is of utmost importance. ETL refers to Extract, Transform, and Load. It supports the movement of data from its source to storage. With ETL testing we ensure that the data is not lost or corrupted during this movement. Huge volumes of data are collected in various formats and sources. The mapping process of these data is error-prone and can have quality issues.

Shunt Voltage References
Analog Devices offers a broad line of shunt precision voltage references that combine excellent accuracy and temperature stability with low noise and small packages. These devices operate in a manner that is functionally equivalent to a Zener diode. The bias current must be set higher than the sum of the maximum quiescent current of the voltage reference and the maximum expected load current. Since shunt voltage references are typically biased with a resistor, the voltage reference can operate on a wide range of input voltages.
