I'm building this circuit and was wondering if a red&grn leds could be used from pin 7 to pin 8 as a duty cycle indicator. The output is rated at 20ma and I would plan to run the LEDs on 1-2ma with only one running at a time it would be minimal load. I was thinking the Vref(virtual gnd) isn't doing much work but maybe 2ma might throw the Vref off? Has anyone done this? Hints?
Thanks
