Dual Channel Central Office ADSL2+ Line DriverThe ISL1535A is a very low power dual channeldifferentiated amplifier designed for central office line drivingfor DMT ADSL2+ solutions. This device features a high drivecapability of 600mA while consuming 7.5mA of supplycurrent per amplifier from ±12V supplies. This driverachieves a typical distortion of less than -75dBc, at 1MHzinto a 50Ω load. The ISL1535A is available in a 28 LdHTSSOP package and a 24 Ld QFN package. This device isspecified for operation over the full -40°C to +85°Ctemperature range.The ISL1535A has two control pins, C0 and C1, per channel.With the selection of C0 and C1, the device can be set intofull-IS power, 3/4-IS power, 1/2-IS power, and power-downdisable modes. The ISL1535A maintains excellent distortionand load driving capabilities even in the lowest powersettings. The ISL1535A has extended bandwidth, low THDand high slew rate for ADSL2+ applications.
