12MHz Rail-to-Rail Buffers + 100mA V

COM

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 V
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 EL5434 is available in the 32-pin QFNQFN
package. They are specified for operation over the full -40°C
to +85°C temperature range.
