The EL1502 is a complete transceiversolution for high speed datatransmission over twisted pair wires. Itcontains two wideband, high-voltage drivers and two lownoisereceive amplifiers. The EL1502 is ideally suited forboth ADSL and HDSL2 applications, in which it can supply a50VP-P signal into a 50Ω differential load while exhibitingvery low distortion. The receive amplifiers also have very lowdistortion and low-noise for superior reception of smallsignals.The line drivers of the EL1502 are current-feedback typeamplifiers, which achieve a high slew rate while consumingmoderate power. They retain their frequency response overa wide range of externally set gains. The receive amplifiersare of the voltage-feedback type and can be used toimplement a hybrid coupler or filter functions using externalpassive components.The EL1502 operates on ±5V to ±15V supplies. It retains itsbandwidth and linearity over the complete supply range.The device is supplied in a standard form factor, 20-pinSOIC package. The eight center package pins of thepackage are used as ground connections and heatspreaders, allowing for operation over the full -40°C to+85°C temperature range.
