Incorporating high gain rectification amp. enable to apply VU/Signal meter widely. Because the output is the constant current pull-in type, the constant current value can be variable by external resistance. 10 0.51min. 6.3±0.25 nection of LEDs 3.8±0.25 • Wide range of constant current : 5mA ~ 25mA • Built-in high gain amp. : GV = 26dB typ. + 0.1 (3.45) 5 0.3 – 0.0 3 ~15˚ 7.62±0.25 18-Lead DIP Package (DIP018-P-0300E) ■ Block Diagram – C1 GND 1 9 16 – Vi 17 VCC R1 + 11 12 13 14 15 – + – + – + – + – + + – + – + – + – + – + VREF Vi 2 + – 10 3 13 RA C1 + – R1 8 7 6 5 4
