ELECTRICAL CHARACTERISTICS
Boldface limits apply over the specified temperature range, TA = –40°C to +125°C.
At TA = +25°C, V+ = 5V, V+IN = 12V, VREF1 = VREF2 = 2.048V referenced to GND, and VSENSE = V+IN – V–IN, unless otherwise
noted.

(1) RTI = referred-to-input.
(2) See typical characteristic graph Figure 20 .
(3) The average of the voltage on pins REF1 and REF2 must be between VGND and the lesser of (VGND+9V) and V+.
(4) Reference divider accuracy specifies the match between the reference divider resistors using the configuration in Figure 37.
(5) See typical characteristic graph Figure 25.
