Table 3. Static Electrical Characteristics
Characteristics noted under conditions -0.3V ≤ V_BUSIN ≤ 30V, 6.0V ≤ V_{H_CAP} ≤ 30V, -40°C ≤ T_A ≤ 125°C,
RTNIN=AGND = 0V, unless otherwise noted. Typical values noted reflect the approximate parameter means at T_A = 25°C under
nominal conditions, unless otherwise noted.
