MAX9650/MAX9651
High-Current V Drive Op Amps for TFT LCDs
General Description
The MAX9650/MAX9651 are single- and dual-channel V amplifiers with rail-to-rail inputs and outputs. The MAX9650/MAX9651 can drive up to 1300m A 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 V 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.
