Tarkkuusjännite

Tarkkuusjännite, also known as precision voltage, refers to a highly stable and accurate direct current (DC) voltage source. This type of voltage is crucial in applications where even minute variations can lead to significant errors or performance degradation. The primary characteristic of a tarkkuusjännite is its extremely low noise and drift, meaning it maintains its output voltage with exceptional consistency over time and across varying environmental conditions such as temperature.

These precision voltage sources are typically achieved through specialized design techniques and high-quality components. This can involve the use of voltage reference integrated circuits (ICs) that are specifically manufactured for high accuracy and stability, often employing bandgap or buried Zener diode principles. Further stabilization is achieved through careful circuit design, including robust power supply filtering, temperature compensation, and shielding to minimize external interference.

Applications for tarkkuusjännite are found in sensitive electronic instrumentation and measurement equipment. This includes analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) where an accurate reference voltage is essential for correct conversion. It is also vital in scientific instruments, calibration standards, laboratory power supplies, and any system requiring precise voltage levels for accurate operation, such as in certain medical devices or high-fidelity audio equipment.
