Texas Instruments OPA548T

The OPA548 device is a low-cost, high-voltage and high-current operational amplifier that’s ideal for driving a wide variety of loads. A laser-trimmed monolithic integrated circuit provides excellent low-level signal accuracy and high-output voltage and current.

The OPA548 device operates from either single or dual supplies for design flexibility. In single-supply operation, the input common-mode range extends below ground.

The OPA548 device is internally protected against over-temperature conditions and current overloads. In addition, the OPA548 device was designed to provide an accurate, user-selected current limit. Unlike other designs, which use a resistor in series with the output current path, the OPA548 device senses the load indirectly. This allows the current limit to be adjusted from 0 A to 5 A with a resistor and potentiometer or controlled digitally with a voltage-out or current-out DAC.

The Enable/Status (E/S) pin provides two functions. An input on the pin not only disables the output stage to effectively disconnect the load, but also reduces the quiescent current to conserve power. The E/S pin output can be monitored to determine if the OPA548 is in thermal shutdown.

The OPA548 device is available in an industry-standard 7-lead staggered and straight lead TO-220 package, and a 7-lead DDPAK surface-mount plastic power package. The copper tab allows easy mounting to a heat sink or circuit board for excellent thermal performance. The device is specified for operation over the extended industrial temperature range, –40°C to 85°C. A SPICE macromodel is available for design analysis.

 

德克萨斯仪器OPA548T
该OPA548装置是一种低成本,高电压和大电流运算放大器的理想驱动各种负载。激光微调单片集成电路提供优良的低信号精度和高输出电压和电流。
该OPA548器件工作在单或双电源设计的灵活性。在单电源工作时,输入共模范围扩展到地面以下。
该OPA548装置内防超温条件和电流过载。此外,该OPA548装置的设计提供准确的,用户选择的电流限制。不像其他的设计,使用一个电阻与输出电流路径系列,该OPA548装置感应负载间接。这允许电流限制从0 A到5 A调整为电阻器和电位器,或用电压输出或电流输出DAC进行数字控制。
启用/状态(E / S)引脚提供两个功能。一个引脚上的输入不仅禁用输出级有效地断开负载,而且还减少了静态电流,以节省电力。E / S引脚输出可以监测确定OPA548是热关断。
该OPA548装置在一个行业标准七导联交错、直导线的TO - 220封装是可用的,和一个七导联DDPAK封装的表面贴装塑料功率。铜选项卡允许轻松安装到散热片或电路板的优良的热性能。该装置规定工作在扩展工业温度范围,–40°C 85°C的SPICE宏模型可用于设计分析。
