Notes and Cautions:

Logic inputs are MOS gates. I

IN typically is less than 1nA @ 25°C.

Guaranteed by design, but not production tested.

Unipolar: Using the internal R

FEEDBACK with nulled external amplifier in a constant 25°C ambient (offset doubles every 10°C).

Using internal feedback resistor.

Integral Linearity, for this product, is measured as the arithmetic mean value of the magnitudes of the greatest positive deviation

and the greatest negative deviation from the theoretical value for any given input combination.

Differential Linearity is the deviation of an output step from the theoretical value of 1 LSB for any two adjacent digital input codes.

The SP9316 series is designed to be used only in those applications where the current output is virtual ground; i.e. the summing

junction of an op amp in the inverting mode. The internal feedback resistor must be used to achieve temperature tracking. See

applications information for recommended circuit configurations.

For military temperature range product, screened to MIL-STD-883C, please consult the factory.

Sample tested only to ensure compliance.

O1 load RL = 100Ω, CEXT = 13pF; all data inputs 0V to VDD or VDD to 0V; from 50% digital input change to 90% of final analog

output.
