(1)

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

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

(2)

This slew rate is the average of the rising and falling time estimated from the large-signal bandwidth as: (0.8 × VPEAK / √2) × 2π × f–3dB

where this f–3dB is the typical measured 2-VPP bandwidth at gains of 1 V/V.

(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. Typical drift specifications are ±1sigma. Maximum drift

specifications are set by min/max sample packaged test data using a wafer-level screened drift. Min/Max drift is not specified by final

automated test equipment (ATE) nor by QA sample testing.

(4)

Current is considered positive out of the pin.

at VS+ = 5 V, VS– = 0 V, RF = 0 Ω, RL = 2 kΩ, G = 1 V/V, input and output referenced to mid-supply, and TA ≈ 25°C (unless

otherwise noted)
