AFE031,pdf(Powerline Communica

The AFE031 is a low-cost, integrated powerline communications analog front-end (AFE) device that is capable of a transformer-coupled connection to the powerline while under the control of a DSP or microcontroller. It is ideal for driving high-current, low-impedance lines that drive up to 1.5A into reactive loads. The integrated receiver is able to detect signals down to 15µV_RMS 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.

The AFE031 transmit power amplifier operates from a single supply in the range of 7V to 26V. At maximum output current, a wide output swing provides a 13V_PP (I_OUT = 1.
