Description

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.

Applications

• TFT-LCD V_COM supplies for
• LCD-TVs
• LCD monitors
