| (R) EL5228 Data Sheet March 25, 2004 FN7368 PRELIMINARY VCOM with Dual Gamma Buffer 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/s. The VCOM amplifier has a 44MHz bandwidth and 80V/s 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 -40C to +85C temperature range. Features * High power VCOM amplifier - 180mA peak (65mA typ.) output current - 55MHz bandwidth - 75V/s slew rate * Dual gamma buffers - 120mA peak (30mA typ.) output current - 12MHz bandwidth - 10V/s slew rate * Just 3.5mA supply current * Small DFN-10 package Pinout EL5228 (10-PIN DFN) TOP VIEW TOP VIEW VOUTA 1 VINA 2 VDD 3 VINC+ 4 VINC- 5 THERMAL PAD 10 VOUTB 9 VINB 8 VSS 7 NC 6 VOUTC Applications * TFT-LCD displays * Flat panel monitors * Notebook displays * LCD-TVs Ordering Information PART NUMBER EL5228IL EL5228IL-T13 EL5228IL-T7 PACKAGE 10-Pin DFN 10-Pin DFN 10-Pin DFN TAPE & REEL 13" 7" PKG.
