The MAX4310–MAX4315 family provides high‑speed, low‑power, single‑supply multiplexed video amplifiers. Devices are offered in 2‑, 4‑ or 8‑channel versions with either adjustable unity‑gain or fixed +2 V/V gain, optimized for broadcast‑video applications.
Key features include 40 ns channel‑switching time, ultra‑low 10 mV p‑p switching transients, rail‑to‑rail inputs and outputs, and a low quiescent current of 6.1 mA (560 µA in shutdown). The series operates from +4 V to +10.5 V (or ±2 V to ±5.25 V) and supports high‑speed video‑line driving up to 20 pF loads.
