MAX9650/MAX9651 High-Current VCOM Drive Op Amps for TFT LCDs General Description Features The MAX9650/MAX9651 are single- and dual-channel 1300mA Peak Output Current VCOM amplifiers with rail-to-rail inputs and outputs. The Rail-to-Rail Inputs and Outputs MAX9650/MAX9651 can drive up to 1300mA of peak current per channel and operate up to 20V. Operates Up to 20V The MAX9650/MAX9651 are designed to source and 40V/s Slew Rate sink a high current quickly to hold the VCOM voltage stable in large TFT-LCD panels. 35MHz Bandwidth The MAX9650/MAX9651 feature 40V/s slew rate and 5mA Quiescent Current per Channel 35MHz bandwidth to quickly settle outputs for 120Hz Excellent Heat Dissipation (Exposed Pad) frame rate and full HD television. The MAX9650/MAX9651 feature output short-circuit protection and thermal shutdown. These devices are Ordering Information available in exposed pad packages for excellent heat dissipation.
