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