Texas Instruments AFE031 Powerline Communications Analog Front End

Texas Instruments AFE031 Powerline Communications Analog Front End (AFE) is a low-cost, integrated powerline communications device. These devices are capable of capacitive- or transformer-coupled connections to the powerline while under the control of a DSP or microcontroller. The Texas Instruments AFE031 amplifiers are ideal for driving low-impedance lines that require up to 1.5A into reactive loads. The integrated receivers can detect signals down to 20µVRMS and can use a wide range of gain options to adapt to varying input-signal conditions. These monolithic integrated circuits provide high reliability in demanding powerline communications applications.
