Integrated buffers cut display flicker

A new series of multichannel gamma buffers with integrated high-speed V(COM) amplifiers promises to boost the performance of TFT LCDs.

The EL5524, EL5624, EL5724 and EL5824 integrate four, six, eight and ten gamma buffers, respectively, and each includes a single high-speed V(COM) amplifier for higher performance and lower cost. These advanced ICs provide the added performance needed for new applications, particularly where the V(COM) amplifier processes charge injection cancelling signals to help eliminate annoying flicker in newer-generation displays. The EL5524, EL5624, EL5724 and EL5824 deliver rail-to-rail input and output performance, a slew rate of 15V/us and 140mA peak output drive current.

Each IC also includes a single high-performance V(COM) amplifier that boasts of a 60MHz bandwidth, a 90V/us slew rate and 200mA peak-output drive capability.

The high performance of these new devices helps reduce picture-degrading flicker and improve the video-viewing experience offered by TFT LCDs.

Other current and previous-generation V(COM) amplifiers cannot process high-speed feedback signals fast enough to provide this level of performance.

The suggested resale price in 10,000-unit quantities is $1.46 for the EL5524IRE, $1.61 for the EL5624IRE, $1.75 for the EL5724IRE and $1.90 for the EL5824IRE.
