REV. A
Temperature ranges are as follows: J Version: 0 C to +70 C; A Version: –40 C to +85 C; S Version: –55 C to +125 C.
Measured with respect to REF IN and includes bipolar offset error.
For capacitive loads greater than 50 pF, a series resistor is required (see Internal Reference section).
Sample tested @ +25 C to ensure compliance.
