ISL1535 - Dual Channel Central Office ADSL2+ Line Driver

The ISL1535 is a very low power dual channel differentiated amplifier designed for central office line driving for DMT ADSL2+ solutions. This device features a high drive capability of 600mA while consuming 5.2mA of supply current per amplifier from ¡À12V supplies. This driver achieves a typical distortion of less than -75dBc, at 1MHz into a 50¦¸ load. The ISL1535 is available in 28 Ld HTSSOP package. This device is specified for operation over the full -40¡ãC to +85¡ãC temperature range. The ISL1535 has two control pins, C₀ and C₁, per channel. With the selection of C₀ and C₁, the device can be set into full-I_S power, 3/4-I_S power, 1/2-I_S power, and power-down disable modes. The ISL1535 maintains excellent distortion and load driving capabilities even in the lowest power settings. The ISL1535 has extended bandwidth, low THD and high slew rate for ADSL2+ applications.
