AC ELECTRICAL CHARACTERISTICS The l denotes specications that apply over the full operating
temperature range, otherwise specications are at TA = 25°C. Typical AC electrical performance measured in demo board DC1464A
(Figure 3, Test Circuit A) unless otherwise noted. Default operating conditions are VCC = 3.3V, EN = 0.8V, SHDN = 2.2V, +VG tied to VREF
(negative gain slope mode), and ZSOURCE = ZLOAD = 50Ω unless otherwise noted.
