trying to test ad5542a dac ic on breadboard without its complementary components(as recommended in one of the circuit notes provided for it).
Using SPI protocol, clock @8.33MHz .power supply used is 5V ,reference input is provided 2.4V, VLOGIC=5V,CLR is pulled up, LDAC is grounded. On serial data I am providing 5 samples as follow 0x0000, 0x3000, 0x8000, 0xC000, 0xFFFF.
As i am not using any output buffer so its unipolar output should swing from 0V to vref i. e. 0v to 2.5 v as vref=2.5V. But output seems to offset by 1.9v and also whole output is compressed to just 1.9v to 2.4v only.
please suggest some solution.
thanks in advance...
