Description
The EL5228 integrates a high power VCOM amplifier with dual gamma reference voltage buffers. With 180mA peak and 65mA typical output current, the VCOM amplifier is suitable for all sizes of LCD displays. The dual gamma buffers can output 30mA typical, 120mA peak and feature a bandwidth of 12MHz and a slew rate of 15V/µs. The VCOM amplifier has a 44MHz bandwidth and 80V/µs slew rate.
The EL5228 operates from just 3.5mA typical supply current and is packaged in the high-power DFN-10 package. It is specified for operation over the -40°C to +85°C temperature range.
Applications
- TFT-LCD displays
- Flat panel monitors
- Notebook displays
- LCD-TVs
