DAC0800 not working as per datasheet specifications.

[u7karsh]

Hello everyone.
I have a digital to analog convertor DAC0800 that requires parallel input bits.. In the data sheet, according to my package, it shows me the following circuitry to get it working..


The following is my system, where i have connected it in exact same manner as data sheet says will all voltages correct and v+ and v- being +18 and 18V respectively.. But still, as per the output, no current is flowing.. kindly help me solve this issue..

Hello,

I am having the exact same problem. I'm driving the digital inputs from a 74HC573 and I have the V_LC pin grounded. Perhaps that is the problem. I'm also powering it from several different power supplies and I may have damaged it with an improper turn-on sequence. Did you find a solution?

Thans,
Mike

I am having the exact same problem.

Is it so? u7karsh is describing a pure simulation problem. It sounds like you are working with real hardware?

Yes, real hardware. Thanks
