Electrical Characteristics

(VDD = +5V, VSS = 0V, VCM = VDD/2, VOUT = VDD/2, RL=100K tied to VDD/2, SHDNB = VDD, TA = -40°C to

+85°C, unless otherwise noted. Typical values are at TA =+25°C.) (Notes 1)

Note 1: All devices are 100% production tested at TA = 25℃; all specifications over the automotive

temperature range is guaranteed by design, not production tested.

Note 2: Parameter is guaranteed by design.
