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 50 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. Features • Complete ADSL differential driver and receiver • 54VP-P output drive into 100 differential • 50VP-P output drive into 50 differential • Driver 2nd/3rd harmonics of -70dBc/-75dBc at 2VP-P into 100 • Low supply current 12.5mA per drive amplifier and 5mA per receive amplifier • Standard surface-mount package Applications • ADSL line driver • HDSL2 line driver • Video distribution amplifier Pinout EL1502 (20-PIN SO) TOP VIEW The EL1502 operates on ±5V to ±15V supplies. It retains its bandwidth and linearity over the complete supply range. Ordering Information PART NUMBER PACKAGE EL1502CM 20-Pin SO TAPE & REEL PKG.
