Four bias modes are available via the use of two digital bits (PD1, PD0). Additionally, the AD8392AACP provides VCOM pins for on-chip, common-mode voltage generation. The low power consumption, high output current, high output voltage swing, and robust thermal packaging enable the AD8392A to be used as the CO line drivers in ADSL and other xDSL systems. Rev.
