1 / 2 page 1 ® FN6369.2 ISL1532A Dual Channel Fixed Gain Differential DSL Line Driver The ISL1532A is a dual channel differential amplifier designed for driving full rate ADSL2+ signals at very low power dissipation. The high drive capability of 450mA makes this driver ideal for DMT designs. It contains two pairs of wideband, high-voltage, current mode feedback amplifiers designed on Intersil’s HS30 Bipolar SOI process for low power consumption in DSL systems. The amplifiers have an internal fixed gain, which helps eliminate both feedback and gain resisitors reducing board size and cost. These drivers achieve an MTPR distortion measurement of better than 70dB, while consuming typically 5mA per DSL channel of total supply current. This supply current can be set using a resistor on the IADJ pin. Two other pins (C0 and C1) can also be used to adjust supply current to one of four pre-set modes (full-IS, 3/4-IS, 1/2-IS, and full power-down). The device is supplied in a thermally-enhanced 20 Ld HTSSOP and the small footprint (4x5mm) 24 Ld QFN packages. The ISL1532A is specified for operation over the full -40°C to +85°C temperature range. The ISL1532A provides larger output swing at heavy loads, higher slew rate, and higher bandwidth while maintaining pin-to-pin drop-in compatibility with the EL1528. The ISL1532A integrates 50k pull-up resistors on CO and C1 pins.
