Dual VCOM Amplifier & Gamma Reference Buffer

The EL5128 integrates two VCOM amplifiers with a single gamma reference buffer. Operating on supplies ranging from 5V to 15V, while consuming only 2.0mA, the EL5128 has a bandwidth of 12MHz (-3dB) and provides common mode input ability beyond the supply rails, as well as rail-to-rail output capability. This enables the amplifier to offer maximum dynamic range at any supply voltage. The EL5128 also features fast slewing and settling times, as well as a high output drive capability of 30mA (sink and source).
