Renesas' VCOM calibrators are used to remove flicker in LCD panels by adjusting the VCOM voltage. The product portfolio includes programmable current sinks that can be used in conjunction with an external voltage divider to generate a voltage source (VCOM) positioned between the analog supply voltage and ground. Various VCOM amplifiers are also available, including rail-to-rail input-output operational amplifiers and rail-to-rail input-output buffers that are ideal for display applications.
