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.
ELECTRICAL CHARACTERISTICS (continued)
(VDD = +15V, VSS = -15V, GND = 0, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
