LMH6654/55 is a single/dual low power, 250MHz, low noise amplifier.
The LMH6654/55 are single‑ and dual‑channel, low‑power, high‑speed voltage‑feedback amplifiers designed for a unity‑gain stable operation with a 250 MHz bandwidth. They operate from a single supply of +2.5 V to +6 V, drawing only 4.5 mA per channel, and feature low input‑referred noise and wide output swing.
The device is offered in several packages (SOT‑23‑5, SOIC‑8, MSOP‑8) and includes detailed electrical characteristics, absolute maximum ratings, and typical performance graphs for applications such as ADC drivers, consumer video, active filters, and xDSL receivers.
