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 previ-
ously required system components and complies with
the HomePlug
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.
