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 i...
