NOTES
1_{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.}
2_{Measured with respect to REF IN and includes bipolar offset error.}
3_{For capacitive loads greater than 50 pF, a series resistor is required (see Internal Reference section).}
4_{Sample tested @ +25°C to ensure compliance.}
Specifications subject to change without notice.
