ADA4312-1 Wideband, Differential, High Output Current Line Driver with Shutdown

The ADA4312-1 is available in a thermally enhanced, 16-lead LFCSP with an exposed pad to facilitate robust thermal management. The ADA4312-1 is rated to operate over the extended industrial temperature range of −40°C to +85°C. Applications ITU G.hn (ITU G.9960/G.9961) HomePlug AV HomePlug AV2 IEEE 1901

The ADA4312-1 is a high speed, differential, current feedback line driver designed for half-duplex G.hn power line communication (PLC) modems. The high output current, high bandwidth, and slew rate of 2100 V/μs make the ADA4312-1 an excellent choice for G.hn broadband applications that require high linearity while driving low impedance loads.

The CMOS-compatible shutdown control pin (SD) reduces the quiescent current to 3 mA while maintaining an output impedance of 10 kΩ differential. The ADA4312-1 also provides resistor adjustable quiescent current for improved efficiency in transmit mode.
