Figure 6-44 shows a MAX934 connected as a simple, four-stage level detector with LED readouts. The full-scale threshold (all LEDs on) is given by VIN=(R1 + R2)/R1 volts. The other thresholds are at 3/4 full-scale, 1/2 full-scale, and 1/4 full-scale. The output resistors limit the current into the LEDs. MAXIM NEW RELEASES DATA BOOK, 1995, P. 3-58.
