The AFE031 is a low-cost, integrated, powerline communications (PLC) analog front-end(AFE) device that is capable of capacitive- or transformer-coupled connections to the powerlinewhile under the control of a DSP or microcontroller. It is ideal for driving low-impedance linesthat require up to 1.5 A into reactive loads. The integrated receiver is able to detect signalsdown to 20 μVRMS and is capable of a wide range of gain options to adapt tovarying input signal conditions. This monolithic integrated circuit provides high reliability indemanding powerline communications applications.

The AFE031 transmit power amplifier operatesfrom a single supply in the range of 7 V to 24 V. At maximum output current, a wide output swingprovides a 12-VPP (IOUT = 1.5 A) capability with anominal 15-V supply. The analog and digital signal processing circuitry operates from a single3.3-V power supply.

The AFE031 is internally protected against overtemperature and short-circuit conditions.It also provides an adjustable current limit. An interrupt output is provided that indicates bothcurrent limit and thermal limit. There is also a shutdown pin that can be used to quickly put thedevice into its lowest power state. Through the four-wire serial peripheral interface, orSPI?, each functional block can be enabled or disabledto optimize power dissipation.

The AFE031 is housed in a thermally-enhanced, surface-mount PowerPAD package (QFN-48).Operation is specified over the extended industrial junction temperature range of –40°C to+125°C.
