| Description | The AFE031AIRGZR is an analog front-end (AFE) IC from Texas Instruments, designed specifically for power line communication (PLC) applications. It integrates a transmit (Tx) and receive (Rx) signal chain, including a DAC, ADC, programmable gain amplifier (PGA), and filters, ensuring high-performance analog signal processing. The device features a high-efficiency power amplifier (PA) with up to 1.5A output current, enabling reliable signal transmission over power lines. It operates from a single 3.3V or 5V supply and supports various PLC modulation schemes such as FSK, SFSK, OFDM, and BPSK. The AFE031 also includes an SPI interface for configuration, low-power modes for energy efficiency, and an integrated thermal shutdown feature for protection. Its operating temperature range of -40°C to +85°C makes it suitable for industrial and smart grid applications. |
