Description

The EL9200, EL9201, and EL9202 represent programmable VCOM amplifiers for use in TFT-LCD displays. Featuring 1, 2, and 4 channels of VCOM amplification, respectively, each device features just a single programmable current source for adding offset to one VCOM output. This current source is programmable using a single wire interface to one of 128 levels. The value is stored on an internal EEPROM memory. The EL9200 is available in the 12-pin DFN package and the EL9201 and EL9202 are available in 24-pin QFN packages. All are specified for operation over the -40C to +85C temperature range.
