The EL5224, EL5324, and EL5424 feature 8, 10, and 12 low

power buffers, respectively, and one high power output

amplifier. They are designed primarily for buffering column

driver reference voltages in TFT-LCD applications as well as

generation of the VCOM supply. Each low power buffer

features a -3dB bandwidth of 12MHz and features rail-to-rail

input/output capability. The high power buffer can drive

100mA and swings to within 2V of each rail.

The 8-channel EL5224 is available in 24-pin QFN and 24-pin

HTSSOP packages, the 10-channel EL5324 is available in

32-pin QFN and 28-pin HTSSOP packages, and the

12-channel EL5424 is available in the 32-pin QFN package.

They are specified for operation over the full -40°C to +85°C

temperature range.
