Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2:
The LT6018 is capable of producing peak output currents in
excess of 50mA. Current density limitations within the IC require the
continuous RMS current supplied by the output (sourcing or sinking)
over the operating lifetime of the part be limited to under 50mA (Absolute
Maximum). Proper heat sinking may be required to keep the junction
temperature below the absolute maximum rating. Refer to Figure 9, and
the Safe Operating Area section of the data sheet for more information.
Note 3:
Long term input offset voltage stability refers to the average trend
line of offset voltage vs time over extended periods after the first 30 days
of operation.
Note 4:
Guaranteed by design.
Note 5:
The LT6018 input stage is limited to operating between V
–
+ 3V
and V
+
– 3V. Exceeding this input common mode range will cause a
significant increase in input bias current, reduction of open loop gain and
当今的计算机外部设备，都在追求高速度和高通用性。为了满足用户的需求，以Intel为首的七家公司于1994年推出了USB（Universal Serial Bus，通用串行总线）总线协议，专用于低、中速的计算机外设。目前，USB端口已成为微机主板的标准端口；而在不久的将来，所有的微机外设，包括键盘、鼠标、显示器、打印机、数字相机、扫描仪和游戏柄等等，都将通过USB与主机相连。

白光LED光衰原因之荧光粉性能的衰退 到目前，白光 LED、尤其是小功率白光 LED 的发光性能快速衰退已越来越为人们所认识。其实，盲目地夸大宣传，只能将 LED 行业引向歧途，不正视白光 LED 存在的问题，只能延缓白光 LED 应用的发展。只有正视问题、研究问题、尽早解决问题，白光 LED 才能健康、快速发展。 白光 LED 当前面临的一个主要问题就寿命问题。由于白光 LED 的价格尚很...[详细]
