General Description
The EL1508C 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, high-voltage, 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
EL1508C 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 LPP packages. The EL1508C is specified for opera-
tion over the full -40°C to +85°C temperature range.
