Note 1:
Total error when configured as instrumentation amplifier. Assumes ideal op amps.
Note 2:
Each stage (input stage and output stage) is tested for accuracy separately and combined to give the total gain accuracy.
The input stage is tested as follows: OUT1 = 10V, OUT2 = 0. Output stage is tested as follows OUT1 = 10V, OUT2 = 0 and
OUT2 = 10V, OFFSET = 0.
Note 3:
Gain of 1 configuration is open circuit (infinite impedance).
Note 4:
Equivalent load at each pin is calculated according to instrumentation amplifier configuration and assumes ideal op amps.
Note 5:
See
Timing Diagram.
