EL5224, EL5324, EL5424
12MHz Rail-to-Rail Buffers + 100mA VCOM Amplifier
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 Ld QFN and 24 Ld
HTSSOP packages, the 10-channel EL5324 is available in
32 Ld QFN and 28 Ld HTSSOP packages, and the 12-channel
EL5424 is available in the 32 Ld QFN package. They are
specified for operation across the full -40°C to +85°C
temperature range.
