7.5 Electrical Characteristics: (Vs+) – Vs– = 5 V
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.

(1) Test levels (all values set by characterization and simulation): (A) 100% tested at T_A ≈ 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) This slew rate is the average of the rising and falling time estimated from the large-signal bandwidth as: (V_P / √2) · 2π · f_–3dB.
