5 / 24 page  LTC6412 5 6412f AC ELECTRICAL CHARACTERISTICS The l denotes specifications that apply over the full operating temperature range, otherwise specifications 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.
