MAX9650/MAX9651 High-Current VCOM Drive Op Amps for TFT LCDs General Description 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.
