12MHz Rail-to-Rail Buffers + 100mA VCOM Amplifier

The EL5224, EL5324, and EL5424feature 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 VCOMsupply. 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 EL5434 is available in the 32-pin QFNQFN package. They are specified for operation over the full -40°C to +85°C temperature range.
