Description

The MAX2980 powerline communication analog frontend (AFE) integrated circuit (IC) is a state-of-the-art CMOS device that delivers high performance and low cost. This highly integrated design combines an analog-to-digital converter (ADC), digital-to-analog converter (DAC), signal conditioning, and line driver. The MAX2980 substantially reduces previously required system components, while compatible with third-party HomePlug® devices. This device interfaces with the MAX2986 digital transceiver to provide a complete powerline communication solution.

The advanced design of the MAX2980 allows operation without external control, enabling simplified connection to a variety of HomePlug Digital PHY ICs. Additional power-reduction techniques can be employed through the use of various control signals.

The MAX2980 is specified over the 0°C to +70°C commercial temperature range and is offered in a 64-pin TQFP package.
