Description

The EL5524, EL5624, EL5724, and EL5824 integrate a number of gamma reference buffers with a single VCOM amplifier. The EL5524 contains 4 gamma buffers, the EL5624 contains 6, the EL5724 contains 8, and the EL5824 contains 10. Each gamma buffer has a bandwidth of 12MHz and features a slew rate of 15V/s. The output current is rated at 30mA continuous, 140mA peak. The VCOM amplifiers are rated for 60mA continuous output current and 200mA peak. They also feature higher slew rate and bandwidth for use in error cancellation circuits. The EL5524 is available in the 14-pin HTSSOP package, the EL5624 in the 20-pin HTSSOP package, the EL5724 in the 24-pin HTSSOP package, and the EL5824 in the 28-pin HTSSOP package. All are specified for operation over the -40C to +85C temperature range.
