Table 3. Static Electrical Characteristics

Characteristics noted under conditions -0.3V

≤ VBUSIN ≤ 30V, 6.0V ≤ VH_CAP ≤ 30V, -40°C ≤ TA ≤ 125°C,

RTNIN=AGND = 0V, unless otherwise noted. Typical values noted reflect the approximate parameter means at TA = 25°C under

nominal conditions, unless otherwise noted.
