AD8132 VOCM TO ±OUT SPECIFICATIONS
At TA = 25°C, VS = 5 V, VOCM = 2.5 V, G = +1, RL, dm = 499 Ω, RF = RG = 348 Ω, unless otherwise noted. For G = +2, RL, dm = 200 Ω, RF = 1000 Ω, RG = 499 Ω. Refer to Figure 56 and Figure 57 for test setup and label descriptions. All specifications refer to single-ended input and differential outputs, unless otherwise noted.
