Electrical Characteristics: (Vs+) – Vs– = 5 V (continued)

at TA ≈ 25°C, Vocm = open (defaults midsupply), VOUT = 2 VPP, 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
