Texas Instruments AFE031
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 lowimpedance 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.| Part No. | AFE031 |

DESCRIPTION
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 7 V to 24 V. At maximum output current, a wide output swing provides a 12-VPP (IOUT = 1.5 A) capability with a nominal 15-V supply.
