This document introduces the features and characteristics of the LT6552 differential amplifier, including differential to single-ended conversion, video line driver, automotive displays, RGB amplifiers, coaxial cable drivers and low voltage high speed signal processing.
The LT6552 is a video difference amplifier optimized for low‑voltage single‑supply operation. It can be used in differential or single‑ended configurations and supports a wide supply range of 3 V to 12.6 V, delivering rail‑to‑rail output swings and up to 70 mA output drive.
Key electrical characteristics include a 75 MHz -3 dB bandwidth at 3.3 V, 600 V/µs slew rate, >60 dB CMRR at 10 MHz, and operation over –40 °C to 85 °C. The device is offered in 8‑lead SO and tiny 3 mm × 3 mm × 0.8 mm DFN packages, with detailed absolute maximum ratings and typical performance graphs provided.
