DATASHEET
EL9200, EL9201, EL9202
Programmable VCOM
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 LD DFN package and the EL9201 and EL9202 are available in 24 LD QFN packages. All are specified for operation over the -40°C to +85°C temperature range.
