Line Driver-CN6212A

The CN6212A is a differential line driver amplifier designed for power line communication (PLC) applications. It integrates two current-feedback amplifiers, delivering exceptionally low distortion to ensure transmitted signals strictly comply with power spectral mask requirements across PLC frequency bands. The device features a high 1A output current capability, enabling robust performance against significant variations in PLC channel impedance and maintaining signal transmission quality even under heavy loads. Its operating current is externally adjustable via a resistor and can be digitally scaled to 1/2 or 3/4 of the set value through a control pin, allowing software-based optimization of drive performance based on real-time channel conditions. The CN6212A operates over a wide voltage range of up to 28V. The device incorporates on-chip protection circuits, including over-current protection and temperature compensation, ensuring stable and reliable operation under diverse conditions for superior performance in PLC systems. The CN6212A is available in a QFN 4x4-16L package.
