The EL1508 is designed to drive full rate ADSL signals with very low power consumption in CO and CPE applications. Operating temperature range is -40°C to +85°C. The 450mA high drive capability makes this drive ideal for CAP and DMT designs. It contains two wideband, high voltage, current mode feedback amplifiers with many power reduction features.
Pinouts
These drivers achieve MTPR distortion measurements of better than 70dB while typically consuming 6mA of total supply current. The supply current can be set using the resistor on the IADJ pin. The other two pins (C0 and C1) can also be used to adjust the supply current to one of four pre-set modes (full-IS, 2/3-IS, 1/3-IS, and full power off).
The EL1508 operates on ±5V to ±12V power supplies and maintains its bandwidth and linearity throughout the power range. The device offers a thermally-enhanced 20 Ld SOIC(0.300 "), a thermally-enhanced 16 Ld SOIC(0.150 "), and a small footprint (4x5mm) 24 Ld QFN package.
