Linear Technology LT1794 Dual Op Amp Datasheet
The LT1794 is a dual voltage‑feedback op‑amp that delivers a minimum 500 mA output current with low distortion and a high gain‑bandwidth product. It features adjustable supply current, short‑circuit protection, and thermal shutdown, and is offered in a 20‑lead TSSOP or 20‑lead SW package for high‑density designs.
Typical applications include high‑density ADSL central‑office line drivers, SHDSL, HDSL2, G.lite, buffers, test‑equipment amplifiers, and cable drivers. The device’s extended output swing and low‑power operation make it suitable for multi‑port DSL cards and other high‑speed communication systems.
