Electrical Characteristics

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

+125°C, unless otherwise noted. Typical values are at TA =+25°C.) (Notes 1)

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

temperature range is

guaranteed by design, not production tested.

Note 2: Parameter is guaranteed by design.
