AD8392AACPZ-R7

低功耗，高输出电流，四运放，双通道ADSL / ADSL2 +线路驱动器 Low Power, High Output Current, Quad Op Amp, Dual-Channel ADSL/ADSL2+ Line Driver

Product Details

The AD8392A is comprised of four high output current, low power consumption, operational amplifiers. It is particularly well suited for the CO driver interface in digital subscriber line systems, such as ADSL and ADSL2+. The driver is capable of providing enough power to deliver 20.4 dBm to a line, while compensating for losses due to hybrid insertion and back termination resistors.

The AD8392A is available in two thermally enhanced packages, a 28-lead TSSOP_EP AD8392AARE and a 5 mm × 5 mm, 32-lead LFCSP AD8392AACP. 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.
