LTC6431-20 ACELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operatingtemperature range, otherwise specifications are at TA = 25°C (Note 3). VCC = 5V, ZSOURCE = ZLOAD = 50Ω unless otherwise noted.Measurements are performed using Test Circuit A, measuring from 50Ω SMA to 50Ω without de-embedding (Note 4).
