Model LM311PW
Description LMx11 The LM111, LM211, and LM311 series single channel comparators from Texas Instruments are differential input voltage comparators with a wide operating voltage range and a response time of 200 ns. The input of these devices can be isolated from system ground, and the free output can drive power rails or grounded loads. These single channel comparators are equipped with balance and flash functions. ###The Texas Instruments series voltage comparator includes not only traditional single, dual, and four-way comparator packages, but also window comparators and overvoltage and undervoltage monitors. Although comparators and operational amplifiers appear to be similar devices, their operations in practical applications are significantly different. Operational amplifiers are suitable for linear operation with appropriate feedback, while comparators are customized for fast switching and typically operate in open circuit mode. The dedicated voltage comparator has a significantly shorter propagation delay and can have a faster response time under saturation conditions. Most comparators are also more tolerant of high differential input voltages, and many comparators have open collector outputs, allowing them to operate in parallel with other devices.

LM311PW LM311PW TI 完全替代 TSSOP-8
LMx11 系列单路比较器 Texas Instruments 的 LM111、LM211 和 LM311 为差分输入电压比较器,具有宽工作电压范围和 200 ns 的响应时间。 这些设备的输入可从系统接地隔离,自由输出可驱动电源导轨或接地负载。 这些单路比较器配有平衡和闪光灯功能。 ### 比较器,Texas Instruments Texas Instruments 系列电压比较器不仅包括传统单、双和四路比较器封装,还包括窗口比较器及过压和欠压监控器。 尽管比较器和运算放大器表面上是相似的设备,但它们在实用应用中的操作大大不同。 运算放大器适用于线性操作,附带适当反馈,而比较器定制用于快速切换且通常在开路模式中操作。 专用电压比较器具有明显较短的传播延迟,且可在饱和条件下具有更快的响应时间。 大多数比较器还更耐受高差分输入电压,且很多比较器具有开路集电极输出,从而可与其他设备并联操作。
