EL1508

The EL1508 is designed for driving full rate ADSL signals in both CO and CPE applications at very low power dissipation. The high drive capability of 450mA makes this driver ideal for both CAP and DMT designs. It contains two wideband, highvoltage, current mode feedback amplifiers with a number of power dissipation reduction features.

These drivers achieve an MTPR distortion measurement of better than 70dB, while consuming typically 6mA of total supply current. This supply current can be set using a resistor on the IADJ pin. Two other pins (C0 & C1) can also be used to adjust supply current to one of four pre-set modes (full-IS, 2/3-IS, 1/3-IS, and full power-down). The EL1508 operates on ±5V to ±12V supplies and retains its bandwidth and linearity over the complete supply range.

The device is supplied in a thermally-enhanced 20-pin SO (0.300"), a thermally-enhanced 16-pin SO (0.150"), and the small footprint (4x5mm) 24-pin QFN packages. The EL1508 is specified for operation over the full -40°C to +85°C temperature range.
