Precision Voltage References Boost Signal-Chain Performance (.PDF Download)
Signal chains incorporating devices such as analog-to-digital converters (ADCs) or digital-to-analog converters (DACs) often require a voltage reference to assist in the measurement or creation of a precise analog signal. Systems ranging from semiconductor test equipment to medical ultrasound scanners can benefit from references that exhibit minimal gain and noise errors to optimize precision. When choosing a voltage reference, you need to consider potential error parameters ranging from initial accuracy to long-term drift due to aging.
