(VRS+ = VRS- = +36V, VDD = +3.3V, VSENSE = VRS+ -VRS- = 1mV, TA = -40°C to +125°C unless otherwise noted. Typical values are

at TA =+25°C). (Note 2)

Note 2: All Devices are 100% production tested at TA = +25˚C. All temperature limits are guaranteed by design.

Note 3: Gain and offset voltage are calculated based on two point measurements: VSENSE1 = 20% full scale and VSENSE2 = 80%

full scale

Note 4: Output is high-Z during power-up.
