Speed up your op amp prototyping and testing with the DIP adapter evaluation module (DIP-ADAPTER-EVM), which provides a fast, easy and inexpensive way to interface with small surface-mount ICs. You can connect any supported op amp using the included Samtec terminal strips or wire them (...)

LM393是电压比较器，将接在R-Light端的光敏二极管接收光照时产生的电阻值变化变成电压信号传递给电压比较器的同相输入端INB+，这个变化的电压信号与电压比较器的反相输入端INA-端的基准电压相比较，当同相端INB+电压大于反相端INA-端电压时，电压比较器的输出端OUT输出高电平电压，当同相端INB+电压小于反相端INA-端电压时，电压比较器的输出端OUT输出低电平电压，此时LightLED灯亮。 在没有光照时，光敏二极管的电阻值很大，电阻R23与该光敏二极管组成的 …

lm393b 和 lm2903b 可直接替代 lm293、lm393 和 lm2903（“a”和“v”版本）。 所有器件都包含两个独立的电压比较器，这些比较器可在宽电压范围内由单电源供电运行。

2020年5月26日 · LM393 is a widely used voltage comparator IC available in 8 Pin Dip, SO-8 and other packages. This small IC is packed with many good features that make it ideal IC to use as a comparator. The IC contains two separate high accuracy comparator opamps that can be operated from single or dual power supply.

The LM393 series are dual independent precision voltage comparators capable of single or split supply operation. These devices are designed to permit a common mode range−to−ground level with single supply operation.

TI’s LM393 is a Dual differential comparator, commercial grade. Find parameters, ordering and quality information.

Description: Low Offset Voltage Dual Comparators. Manufacturer: ON Semiconductor.
