ELECTRICAL CHARACTERISTICS: V_S+ – V_S– = 5 V (continued)
At V_S+ = +5 V, V_S– = 0 V, V_OCM = open, V_OUT = 2 V_PP (differential), R_F = 1 kΩ, R_L = 1 kΩ differential, G = 1 V/V, single-ended
input, differential output, input and output referenced to midsupply, unless otherwise noted.

(4) Input Offset Voltage Drift, Input Bias Current Drift, and Input Offset Current Drift are average values calculated by taking data at –55°C
and +125°C, computing the difference, and dividing by 180.
