The LT1794 is a dual 500mA, 200MHz xDSL line driver amplifier that exceeds all requirements for full-rate, downstream ADSL line drivers. It has a minimum output current of ±500mA and an output swing of ±11.1V.
The LT1794 is a dual voltage‑feedback amplifier offering a minimum 500 mA output current, 200 MHz gain‑bandwidth, and a 500 V/µs slew rate. It provides low distortion (‑82 dBc at 1 MHz) and adjustable supply current via an external resistor, making it suitable for high‑speed line‑driver circuits.
Typical applications include ADSL, HDSL2, G.lite, SHDSL line drivers, buffers, test‑equipment amplifiers, and cable drivers. The device is available in a 20‑lead TSSOP or 20‑lead SW package for high‑density PCB designs.
