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.
