DSL Line Driver With Power Down

The AD8019 DSL low cost xDSL line driver is optimized to drive minimum 13dBm into low impedance loads while delivering outstanding distortion performance. The highly efficient amplifier architecture delivers 200ma minimum output current into low impedance loads, enabling single +12V designs with a 1:2 transformer turns ratio. The AD8019 is built on a 24V high speed bipolar process which also allows the AD8019 to drive low distortion signals close to ±12V power supply rails. Hybrid designs using the ±12V power supply range of the AD8019 enable the use of 1:1 turns ratio transformer.

* Low distortion, high output current amplifiers operate from +12V to ±12V power supplies, ideal for high performance ADSL or G.Lite CPE xDSL modems. * Low Power Operation - +12V to ±12V Voltage Supply - 9.0mA/Amp (typ) Supply Current - Digital (1-bit) power down * Voltage Feedback Amplifiers
