FUNCTIONAL BLOCK DIAGRAM The XR-2277 and XR-2278 are 12 point level detector circuits designed for direct interfacing to light emitting diode (LED) moving-dot or bar-graph displays.
Each of the circuits is comprised of an input buffer amplifier and 12 comparators, biased from a resistor string at logarithmic intervals.
Accuracy is enhanced by an internal reference.
