Introduction

The ADN2873ACPZ is a high-efficiency laser driver IC specifically designed for photonic integrated circuit applications. The laser driver IC is designed to enable highly efficient DC-DC laser operation, and is built using the latest industry leading CMOS technology for the highest power-to-beds ratio and lowest noise level. It is ideal for applications such as lasers for optical communications, sensors, and medical imaging.

Application Field

The ADN2873ACPZ is a versatile laser driver IC that is suitable for a wide range of applications, including photonic integrated circuits, high-speed short-range communication links, and optical sensing. It is ideal for applications where high efficiency and low power operation are essential due to the relatively low operating voltage of 1.5 V and the small package size.

The device is also ideal for optical communication transmitter applications due to the low dark current, low jitter, and low complementary metal–oxide–semiconductor (CMOS)-compatible drive level. Furthermore, the pulse width modulation (PWM) capabilities of the device enable efficient power delivery in applications such as digital video over fiber, analog video over fiber, and active optical cables. The low-distortion drive level also makes it suitable for applications where high signal integrity is required such as defense, automotive, and aerospace applications.

Working Principle

The ADN2873ACPZ operates using a simplified 4-terminal architecture. The device consists of an integrated voltage regulator, which provides a steady DC output to the laser. The input and output power are independently controllable, allowing the user to easily adjust the optical power output. The IC also provides a low-distortion laser pulse waveform that is generated by an internal function generator. The user is able to set the width and duty cycle of the waveform, allowing for precise control of the laser output.

The ADN2873ACPZ also offers various protection features, including overvoltage, over-temperature, over-current, short-circuit, and undervoltage protection. It also has an adjustable soft-start feature that helps minimize inrush currents during power-up. Additionally, the device has an adjustable shutdown timer that allows the user to safely turn off the laser in the event of a power supply interruption.

Conclusion

The ADN2873ACPZ is a versatile laser driver IC that is suitable for a wide range of application fields. It enables highly efficient DC-DC laser operation, and is built using the latest industry leading CMOS technology. The device provides a low-distortion laser pulse waveform with adjustable duty cycle, and also provides various protection features such as over-temperature, over-current, short-circuit, and undervoltage protection. The ADN2873ACPZ is perfect for applications where high efficiency and low power operation are essential.
