电压温度系数 voltage temperature coefficient
- 对数据采集系统设计最重要的参数是器件的初始误差、输出电压温度系数、热迟滞系数、输出电压噪声、长期稳定度。
The most important parameters for data acquisition systems design are initial error, output voltage temperature coefficient (TC), thermal hysteresis, noise, and long-term stability of the voltage reference device. - 但,人们阅读厂家的数据手册时,因受诸如(电源电压)线性调整率、负载调整率、初始电压误差、输出电压温度系数TC、热迟滞(系数)、静态电流和长期稳定度等参数的影响而使初始精度往往不明显。
But often what is not obvious when reading a manufacturer's data sheet is how the initial accuracy of the device is affected by other key device parameters such as line regulation , load regulation, initial voltage error, output voltage temperature coefficient (TC), output voltage noise, turn-on settling time, thermal hyste-resis, quiescent supply current, and long-term stability. - 仪器的零点读数也会随着环境温度的变化而变化。这种效应通常称为电压偏置温度系数。
The zero reading may also vary as the ambient temperature changes. This effect is usually referred to as the temperature coefficient of the voltage offset.
