i need help to get output from dc245a-a (ltc1668) board.i interface it with DE1 SOC board.
I did following steps but in vain
1)input digital voltages at dac pins yes
2)ref voltage and current correct yes
3)input supply voltages right yes
4)jumpers are ok yes
5)any sign board doesnot respond by removing digital input supply voltage
6)desired output sinewave but no output
7)clock 500mv at pin35 yes
8)does not give output although supply adapter voltage 50 cycle appear at output
9)remove transformer op amp use but output no(same output adapter supply voltage)
