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 powerline while under the control of a DSP or microcontroller. It is ideal for driving low-impedance lines that require up to 1.5 A into reactive loads. The integrated receiver is able to detect signals down to 20 µVRMS and is capable of a wide range of gain options to adapt to varying input signal conditions. This monolithic integrated circuit provides high reliability in demanding powerline communications applications.
