NOTES: (1) USB = Unipolar Straight Binary; BOB = Bipolar Offset Binary. (2) TTL and 5V CMOS compatible. (3) Open DATA input lines will be pulled above +5.5V.
See discussion under LOGIC INPUT COMPATIBILITY in the OPERATION section. (4) Specified with 500Ω Pin 6 to 7. Adjustable to zero with external trim
potentiometer. (5) Error at input code 000
HEX
for unipolar mode, FSR = 10V. (6) Error at input code 800
HEX
for bipolar range. Specified with 100Ω Pin 6 to 4 and
with 500Ω pin 6 to 7. See page 9 for zero adjustment procedure. (7) FSR means Full Scale Range and is 20V for the ±10V range. (8) Maximum represents the
3σ limit. Not 100% tested for this parameter. (9) At the major carry, 7FF
