CNX38US

Optoisolators, also known as optocouplers, opto-isolators, photocouplers, and photoMOS, are electronic devices used to isolate one circuit from another. They allow signals to be sent between two circuits while preventing the two circuits from ground potentials, voltage surges, or other forms of electrical interference. In particular, optoisolators are used to transfer digital signals between circuits as well as for signal isolation. Optoisolators fall into two major categories: Transistor Output Optoisolators and Photovoltaic Output Optoisolators.

The CNX38US is an optoisolator in the Transistor, Photovoltaic Output category.

This device features an LED input that is optically coupled to a photovoltaic output. The LED input changes its current depending on the applied voltage and the output will collect and convert the light emitted by the LED into a voltage. The output is then used to drive a transistor which can be used to control a small external circuitry. This device is typically used in audio applications such as CD players, receivers, amplifiers, and car audio systems since it can provide quick response to transients, decrease crosstalk from one circuit to another and enhance reliability by isolating both input and output signals.

Advantages of the CNX38US optoisolator include a voltaic output of up to 600V DC, a wide operating temperature range of -20 to 65°C, and an excellent dynamic performance across signal frequencies of up to 1MHz. This device is also capable of providing an efficient current transfer ratio (CTR), with values of up to 800% across a wide operating temperature range.

The CNX38US optoisolator is typically used in applications that require signal isolation, such as signal detection, level shifting, and communication between circuits. In addition, this device is also ideal for noise suppression in audio applications, automotive systems, and in power control and protection systems. Moreover, due to its exceptional dynamic performance, the CNX38US is also ideal for use in digital signal processing (DSP) and memory control applications.

The working principle of the CNX38US optoisolator is as follows. This device is composed of an LED input and an optically coupled photovoltaic output. The LED input is connected to a control voltage and a current is passed through it. When the control voltage is applied, the LED emits light that is then collected by the photovoltaic output. This output is then used to drive an external transistor which is used to control small external circuitry. The output from the transistor is typically used to control or drive circuits.

In summary, the CNX38US is an optoisolator from the Transistor, Photovoltaic Output category. This device is used to provide isolation between two circuits and can be used in audio applications, automotive systems, power control, and video applications. Additionally, this optoisolator also has excellent dynamic performance which makes it ideal for use in DSP and memory control applications. Finally, the working principle of this device involves passing a current through an LED input which converts light into an output voltage that then drives an external transistor.
