The MAX9650/MAX9651 are single- and dual-channel VCOM amplifiers with rail-to-rail inputs and outputs. The MAX9650/MAX9651 can drive up to 1300mA of peak current per channel and operate up to 20V. The MAX9650/MAX9651 are designed to source and sink a high current quickly to hold the VCOM voltage stable in large TFT-LCD panels. The MAX9650/MAX9651 feature 40V/µs slew rate and 35MHz bandwidth to quickly settle outputs for 120Hz frame rate and full HD television. The MAX9650/MAX9651 feature output short-circuit protection and thermal shutdown. These devices are available in exposed pad packages for excellent heat dissipation.
The MAX9650 and MAX9651 are single‑ and dual‑channel VCOM amplifiers designed to drive up to 1300 mA peak current per channel and operate from 6 V to 20 V (or dual 4.5 V‑10 V supplies). They feature rail‑to‑rail inputs and outputs, 40 V/µs slew rate, 35 MHz bandwidth, and built‑in short‑circuit protection with thermal shutdown.
The datasheet provides absolute maximum ratings, detailed electrical characteristics, pin descriptions, package options (SOT‑23, UMAX‑EP, TDFN‑EP), layout recommendations, and ordering information for both standard and automotive‑qualified parts.
