EL4543 is a high bandwidth triple differential amplifier with integrated encoding of video sync signals
The EL4543 is a high‑bandwidth triple differential amplifier that integrates video sync encoding for twisted‑pair or coax transmission. It supports single‑ended or differential inputs, operates from a single 5 V to 12 V supply, and handles -40 °C to +85 °C ambient temperatures, making it suitable for VGA over twisted‑pair, differential line drivers, and noisy‑environment analog signal transmission.
Key specifications include a 350 MHz -3 dB bandwidth, 1200 V/µs slew rate, 50 mA minimum output current, and low‑power consumption of 36 mA typical. The device is offered in 24‑lead QSOP and 20‑lead QFN packages, with detailed pin descriptions, absolute maximum ratings, and extensive performance curves provided in the datasheet.
