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.  
Figure 2. Typical PLC Driver Application  
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.
