The LX1801ILQ is a high-performance, open-collector digital isolator designed for automotive, industrial and medical applications. Open-collector digital isolators are used to isolate groups of electronics from each other while still allowing them to share signals and information. This isolator type reduces the effects of EMI/RFI, voltage spikes, and radio frequency interference on delicate equipment. This makes the LX1801ILQ suitable for any environment that is subject to high levels of EMI/RFI.

The LX1801ILQ is an 8-bit, 24 pin device with selectable power reduction mode and high performance channel-to-channel isolation (up to 1000V RMS). It works with a wide range of power supplies, from 3.3V to 5.5V and features a maximum operating temperature range of -40° to +85° Celsius. In addition, the device is stress tested to ensure its superior long-term reliability.

The LX1801ILQ application field is focused on data acquisition and signal conditioning. It can be used in conjunction with data acquisition boards and other signal conditioning devices to isolate and condition signals for digital communication or peer-to-peer communication between multiple microcontroller or digital logic devices. The LX1801ILQ can also be used to provide input isolation in motor control, power management, and avionics applications.

The LX1801ILQ working principle uses a combination of isolation barriers and current limiters. The isolation barriers prevent high voltage signals from passing through the device and provide a safe, low-voltage working environment. The current limiters regulate the current that can pass through the device and reduce the chances of damaging the device. This allows the device to safely handle high current and high voltage signals without damaging the internal components.

The LX1801ILQ is a versatile device, suitable for a wide range of applications. It provides a high level of signal isolation and efficient current limitation safeguards. When used in conjunction with other signal conditioning devices, such as ADCs/DACs, it can provide a safe and efficient signal conditioning solution for digital communication or peer-to-peer communication. It is an ideal choice for applications requiring reliable, cost-effective data acquisition and signal conditioning.
