I could not find the military datasheet for AD669 / 883B on your home page.
Please tell us the URL where the AD669 / 883B military datasheet was uploaded.
Our customer has been used in bipolar mode. (0 ~ 10V)
Our customer is prepared in Reference circuit using a volume in the data sheet output offset. (P6)
Can I replace the (± 1.25V / 14bit) circuit constituted by DAC + OP amplifier by eliminating…
The discussion has been moved here,
In my design i used AD669 DAC with unipolar config.
During power down, although LDAC is at ground level and parallel bus is at zero logic DAC output stays 10V while system is shutdown (nearly a few msec).
And since DAC output is 10V the circuit…
