TC826 - A/D CONVERTER WITH BAR GRAPH DISPLAY OUTPUT - TelCom-Semiconductor Datasheet

GENERAL DESCRIPTION
In many applications a graphical display is preferred over a digital display. Knowing a process or system operates, for example, within design limits is more valuable than a direct system variable readout. A bar or moving dot display supplies information precisely without requiring further interpretation by the viewer.
