UM809/810
Electrical Characteristics (Continued)
VCC = full range, TA = -40°C to +105°C (SOT23) or TA = -40°C to +125°C (SC70), unless
otherwise noted. Typical values are at TA =+25°C, VCC = 5V for L/M/J versions, VCC = 3.3V for
T/S versions, VCC = 3V for R version, and VCC = 2.5V for Z version. (Note 1)
