Electrical Characteristics: Vs+ – Vs– = 5 V (continued)
At T_A ≈ 25°C, Vocm = open (defaults midsupply), V_OUT = 2 V_PP, Rf = 402 Ω, Rload = 499 Ω, 50-Ω input match, G = 2 V/V,
single-ended input, differential output, and PD = +Vs, unless otherwise noted. See Figure 61 for an ac-coupled gain of a
2-V/V test circuit, and Figure 63 for a dc-coupled gain of a 2-V/V test circuit.

(3) Input offset voltage drift, input bias current drift, input offset current drift, and Vocm drift are average values calculated by taking data at
the at the maximum-range ambient-temperature end points, computing the difference, and dividing by the temperature range. Maximum
drift set by distribution of a large sampling of devices. Drift is not specified by test or QA sample test.
