NOTES
1Temperature ranges are as follows: J Version, 0°C to +70°C; A Version, –40°C to +85°C.
2VOUT (p-p) = ± 3 V.
3SNR calculation includes distortion and noise components.
4Using external sample and hold, see Figures 13 to 15.
5Measured with respect to REF IN and includes bipolar offset error.
6For capacitive loads greater than 50 pF a series resistor is required (see Internal Reference section).
7Sample tested @ +25°C to ensure compliance.
