ELECTRICAL CHARACTERISTICS (continued)
(VRSB = VRS+ = VRS- = +12V, VDD = +3.3V, VGND = 0, VREF = VDD/2 for bidirectional, VREF = 0 for unidirectional, VSENSE = VRS+ - VRS- = 0,
MAX9922 is set for AV =100V/V (R1 = 1kΩ, R2 = 99kΩ), SHDN = VDD, TA = -40°C to +85°C, unless otherwise noted. Typical values are at
TA = +25°C.) (Note 1)
