Programmable V
Features
• 128 step adjustable sink current
COM
The EL9200, EL9201, and EL9202 represent programmable
V
amplifiers for use in TFT-LCD displays. Featuring 1,
COM
2, and 4 channels of V
• EEPROM memory
amplification, respectively, each
COM
device features just a single programmable current source
for adding offset to one V output. This current source is
• 2-pin adjustment and disable
COM
• Single, dual or quad amplifiers
- 44MHz bandwidth
- 80V/µs slew rate
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.
- 60mA continuous output
- 180mA peak output
• Up to 18V operation
• 2.6V to 3.6V logic control
• Pb-free available (RoHS compliant)
