I am using AD669 in bipolar and we are facing the issues .
following are the details of the circuit
1. /CS, /L1 and LDAC are all tied each other
2. To write data we are following timing diagram of figure 1b from datasheet
3. /CS, /L1 and LDAC (control…
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…
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…
I have a board with AD669 (PDIP package), powered by an external power supply and three voltage regulators (+15V, -15V, +5V), working in the bipolar configuration (wired up as recommended on the page 16 of the AD669BNZ datasheet, with 50Ohm resistors…
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.
