7.6 Electrical Characteristics: VS = 2.7 V (continued)

at VS+ = +2.7 V, VS– = 0 V, VOUT = 1 VPP, RF = 0 Ω, RL = 2 kΩ, G = 1 V/V, input and output referenced to mid-supply, VIN_CM =

mid-supply – 0.5 V. TA = 25°C, unless otherwise noted.

(1)

Test levels (all values set by characterization and simulation): (A) 100% tested at 25°C; over temperature limits by characterization and

simulation. (B) Not tested in production; limits set by characterization and simulation. (C) Typical value only for information.

(2)

Current is considered positive out of the pin.

(3)

Input Offset Voltage Drift, Input Bias Current Drift, and Input Offset Current Drift are average values calculated by taking data at the

end points, computing the difference, and dividing by the temperature range.
