Optoisolators are devices designed to provide a means of electrical isolation between two circuits, while keeping a signal path open. Among the different types of optoisolators available, the LTV-824 is one such optoisolator, utilizing a transistor photovoltaic output. The LTV-824 optoisolator is a single channel device, with a 40 Volt P emitter output transistor and requires a 4V drive voltage.

The LTV-824 optoisolator is suitable for applications such as sensor signal transmission, pulse amplifier isolation and input signal measurement for analog-to-digital converters. It is also used for ground loop correction, isolation in mixed signal systems, and communication signal transmission. It is available in through-hole as well as surface mount package types.

The working principle of the LTV-824 optoisolator involves the use of an infrared LED and a phototransistor, which are separated by a 6mm air gap and sealed in a compact white package. The infrared LED emits infrared light when current is passed through it, which is detected by the phototransistor and is then amplified through the transistor output. The transistor output drives a load circuit, which is responsible for performing the necessary functions.

The optoisolator isolates the two circuits from each other by means of the internal gap, eliminating any contact between the source and the load circuits. Furthermore, the voltage isolation between the two circuits is also improved due to the optoisolator’s high isolation voltage rating. This ensures that the voltage differences between the source and load are kept to a minimum and are not allowed to affect each other. Thus, the optoisolator can be used to maintain electrical isolation while enabling signal transfer between the two circuits.

The LTV-824 optoisolator is designed to operate reliably and efficiently over a wide range of temperatures, ranging from -40°C to 100°C. Furthermore, the device is available in multiple output signal shapes, such as logic low, logic high, and non-logic signal outputs. Additionally, the optoisolator also features a UL Recognized rating, making it suitable for use in industrial and commercial applications where safety is a priority.

The LTV-824 optoisolator is a reliable and cost-effective solution for applications requiring electrical isolation and signal transmission between two circuits. With its wide temperature range, varied output signals and UL Recognized rating, the device can be used in a variety of industrial and commercial applications, providing enhanced security and efficiency.
