LMH6555 is a low distortion 1.2GHz differential driver with 53dB SFDR at 750MHz. The device features a fixed gain of 13.7dB, an input to the device allows the output common mode voltage to be set independent of the input common mode voltage in order to simplify the interface to high speed differential input ADCs. A unique architecture allows the device to operate as a fully differential driver or as a single-ended to differential converter. The outstanding linearity and drive capability (100Ω differential load) of this device are a perfect match for driving high speed analog-to-digital converters. When combined with the ADC081000/ ADC081500 (single or dual ADC), the LMH6555 forms an excellent 8-bit data acquisition system with analog bandwidths exceeding 750MHz.
The LMH6555 is an ultra‑high‑speed differential line driver offering a fixed gain of 13.7 dB and 53 dB SFDR at 750 MHz. It can operate as a fully differential driver or as a single‑ended‑to‑differential converter, supporting up to a 1.2 GHz bandwidth and a slew rate of 1300 V/µs.
Typical applications include driving high‑speed ADCs such as the National Semiconductor ADC081500/ADC081000, as a single‑ended‑to‑differential converter, or in communication receivers and oscilloscope front‑ends. The device is supplied in a 16‑pin LLP package and is designed for a 3.3 V single‑supply operation.
