The OP705D is a phototransistor optical sensor that has a wide range of applications in various industries. It is a compact and low-power device with a wide operating voltage range that makes it suitable for many applications. The OP705D features a high sensitivity wide-angle optical sensing range and a low-end trade-off between sensitivity and stability. The OP705D has a 6-pin package and is available in two different current versions, one with a current output of up to 100mA when driven by a 5V supply, and one with a current output of up to 200mA when driven by a 12V supply. With its combination of features, the OP705D offers a solution for almost any application requiring a phototransistor sensor.

The OP705D is a two-channel phototransistor sensor that consists of an array of two phototransistors each made of an array of two transistors. It is designed to detect light in the visible range of spectral wavelengths from 400nm to 1100nm. The two phototransistors are arranged in a differential configuration, and the output of the sensor is the difference between the two phototransistors. This differential arrangement allows the device to operate from a wide range of visible light wavelengths while rejecting any incident light from non-visibly light sources such as infrared or ultraviolet. The OP705D has a high efficiency of up to 70% and an extended operating temperature range of -20°C to 85°C.

The OP705D has a wide range of uses in various industries. Its wide operating voltage range allows it to be used in a wide range of applications, including motion detection systems, robotics, bar-code readers, assembly line automation, general industrial, medical, and security systems. Furthermore, its robust 6-pin package design makes it ideal for applications where space is scarce.

The working principle of the OP705D is quite simple. When exposed to light, the two phototransistors produce a current which is then output as a voltage. This voltage then follows the input of the op-amp that is present in the OP705D. The op-amp acts as an amplifier and produces a proportional output current. The current is then output from the OP705D, and can be used to control a variety of devices, such as relays, motors, LED lights, etc.

In conclusion, the OP705D is an extremely versatile phototransistor optical sensor that is suitable for a wide range of applications. Its small size and low power requirements make it ideal for a wide range of designs, from motion detection systems to bar-code readers. Furthermore, its differential configuration allows it to reject incident light from non-visible sources such as infrared and ultraviolet, while still utilizing the light from the visible range of wavelengths. The OP705D is thus an excellent choice for many applications requiring a reliable and accurate phototransistor sensor.
