LTC6431-20
AC ELECTRICAL CHARACTERISTICS The
l
denotes the specifications which apply over the full operating temperature 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). SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS Small Signal
