The ISL1535A 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 7.5mA of supply current per amplifier from ±12V supplies. This driver achieves a typical distortion of less than -75dBc, at 1MHz into a 50Ω load. The ISL1535A is available in a 28 Ld HTSSOP package and a 24 Ld QFN package. This device is specified for operation over the full -40°C to +85°C temperature range.

The ISL1535A has two control pins, C₀ and C₁, per channel. With the selection of C₀ and C₁, the device can be set into full-IS power, 3/4-I_S power, 1/2-I_S power, and power-down disable modes. The ISL1535A maintains excellent distortion and load driving capabilities even in the lowest power settings. The ISL1535A has extended bandwidth, low THD and high slew rate for ADSL2+ applications.
