数字电位器

像可变电阻器、变阻器和机械电位器一样，数字电位器具有调节和微调电子电路的功能。数字电位器有时也称为数字 POT、RDAC 或 Digipot,这些小巧的器件可用于校准系统允许误差或者动态控制系统参数。当电源断电后并且重新接通时，带非易失存储器的数字电位器提供滑动点设定值保存功能。此外，采用熔丝链技术的数字电位器还提供一次性可编程功能。Part# Resul # Channels # Positions Memory Type Interface Resistor Values (kOhms) Bipolar Voltage Range (V) Voltage Range (V) Supply Current Temp.
