32-Bit Duplex/Triplex VFD Controller/Driver With Digital Dimming, ADC And Keyscan

The ML9226 is a full CMOS controller/driver for Duplex or Triplex Vacuum Fluorescent Display tube. It conststs of 32-segment driver outputs and 3-grid pre-driver outputs, so that it CAN drive directly up to 96-segment VFD ML9226 features a digital dimming function, a 8-ch ADC a 5 5 keyscan circuit and an encoder type Switch Interface ML9226 provides an Interface with a Microcontroller only by four signal lines: DATA I/O, Clock CS.
