EL1502 pdf datasheet (High Pow

The EL1502 is a complete transceiver
solution for high speed data
transmission over twisted pair wires. It
contains two wideband, high-voltage drivers and two lownoise
receive amplifiers. The EL1502 is ideally suited for
both ADSL and HDSL2 applications, in which it can supply a
50VP-P signal into a 50Ω differential load while exhibiting
very low distortion. The receive amplifiers also have very low
distortion and low-noise for superior reception of small
signals.
The line drivers of the EL1502 are current-feedback type
amplifiers, which achieve a high slew rate while consuming
moderate power. They retain their frequency response over
a wide range of externally set gains. The receive amplifiers
are of the voltage-feedback type and can be used to
implement a hybrid coupler or filter functions using external
passive components.
The EL1502 operates on ±5V to ±15V supplies. It retains its
bandwidth and linearity over the complete supply range.
The device is supplied in a standard form factor, 20-pin
SOIC package. The eight center package pins of the
package are used as ground connections and heat
spreaders, allowing for operation over the full -40°C to
+85°C temperature range.
