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.

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.

Product Details

As is the case with many high speed line driver applications, careful attention to printed circuit board (PCB) layout can improve performance and help maintain stability while preventing excessive die temperatures during normal operation. Differential signal balance can be maintained by using symmetry in the PCB layout of input and output signal traces. See AN-772 for complete details.
