NOTES
1
Includes internal voltage reference error.
2
Input voltage range is the linear region over which the input signal can be processed by the input stage of the AD9816.
3
The input limits are defined as the maximum tolerable input voltage into the AD9816. This is not intended to be the linear input range of the device. Signals beyond
the input limits will turn on the overvoltage protection diodes.
4
The total output noise is measured with the inputs of the AD9816 grounded.
5
The channel-to-channel crosstalk is measured with one input grounded, and the other two inputs at full scale.
Specifications subject to change without notice.
