EL9200, EL9201, EL9202
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 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.
