Analog Devices Inc. MAX22088 Home Bus Transceivers
Analog Devices Inc. MAX22088 Home Bus Transceivers comply with home bus standards, passing data and power on one pair of wires while minimizing the need for external components. The series eliminates the large external AC-blocking inductor typically required in bus-powered applications and improves the signal quality to allow for longer cables. The modules feature an integrated 5V linear regulator to power system loads up to 70mA and support passing power and data with speeds up to and exceeding 200kbps. The dynamic cable termination improves signal quality for applications with high data rates. The MAX22088's receiver hysteresis, receiver thresholds, and driver slew rate are adjustable. Integrated protection ensures robust communication in harsh industrial environments. Analog Devices Inc. MAX22088 Homebus Transceivers feature an integrated active inductor in a 24-pin 4mm x 4mm TQFN package.Features
