MAX2981

Integrated Powerline Communication Analog Front-End Transceiver and Line Driver

Industry's First Automotive-/Industrial-Grade AFE Plus Line Driver


Please check latest availability status for a specific part variant.

Description

The MAX2981 powerline communication analog front-end (AFE) and line-driver IC is a state-of-the-art CMOS device that delivers high performance at low cost. This highly integrated design combines an analog-to-digital converter (ADC), digital-to-analog converter (DAC), adaptive gain control (AGC), filters, and line driver on a single chip. The MAX2981 substantially reduces previously required system components and complies with the HomePlug® 1.0 standard.

Combined with Maxim's integrated PHY/MAC digital baseband, the device delivers the most flexible and cost-effective solution. The advanced design of the MAX2981 allows operation without external control, enabling simplified connection to a variety of HomePlug 1.0 digital PHY ICs.

The MAX2981 is specified over the -40°C to +105°C automotive temperature range and is offered in a 64-pin lead-free LQFP package. The device is qualified to the AEC-Q100 Rev F automotive standard.
