Description

FUNCTIONAL BLOCK DIAGRAM The XR-2279 is a 12 point logarithmic dot or bar-graph generator/LED driver_ The device compares an input signal with an adjustable reference and graphically displays the results_ Since LED driving current is provided by on board adjustable current sources, no current lim- iting resistors are required.A special feature of the XR2279 is the four highest outputs sink one half the current of the lower eight; this allows equivalent brightness with red and green mixed disp
