ELECTRICAL CHARACTERISTICS (continued)

(VDD = +5V, VREF = +10V, VOUT1 = VOUT2 = 0V, Circuit of Figure 1, TA = TMIN to TMAX, unless otherwise noted.)

Note 1: Gain error is measured using internal feedback resistor. Full-scale range (FSR) = VREF.

Note 2: Gain TempCo measured from +25°C to TMAX and from +25°C to TMIN.

Note 3: Guaranteed by design.
