Part Number: TLC2272A
Hi,
on schematics attached:
+3V3 = 3V30
-3V3 = -2V72 (less than expected)OPAMP is not loaded (I've cut the wire represented by a red cross)
when INPUT is 0..2.5V, the output (pin 7) gets the same value (difference is some few uV, OK it is the offset)
but when INPUT = 2.750V
, the output (pin 7) is 2.80V (greater of 50mV)
I cannot explain that ! Need some help (may be I dont see something)
