FN7438.0
Programmable V
COM
The EL9200, EL9201, and EL9202 represent programmable
V
COM
amplifiers for use in TFT-LCD displays. Featuring 1,
2, and 4 channels of V
COM
amplification, respectively, each
device features just a single programmable current source
for adding offset to one V
COM
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 -40°C to +85°C
temperature range.
