CHARACTERISTICS
V_EEA = V₂₄ to V₅ and V₁₀ = −5.46 to −4.94 V; V_EED = V₃, V₄ and V₁₁ to V₂ and V₂₈ = −5.46 to −4.94 V;
V_EEI = V₂₅ to V₁₂ = −5.46 to −4.94 V; V_EED and V_EEI shorted together; T_amb = 0 to +70 °C; AGND, DGND and IGND
shorted together; V_OUT − V_OUT = 2 V (p-p); Z_L = 50 Ω; unless otherwise specified (typical values measured at
V_EEA = V_EED = −5.2 V and T_amb = 25 °C).
