Hi Felix, Yes, the offset is +/-1.8mV over the full temperature range and all voltage input ranges. Short answer reason is because the only change from +/-5 to +/-10 is the internal sample/hold cap....

Hi Dileep, In order to make sure I understand what you are planning to do, can you please send me a block diagram or schematic? Do you want to DC couple the LMH to the ADC? Or AC couple? I assume DC...

Hi Rachael Parker, I don't know much about measuring resistor noise, the only method I have ever seen is to measure the intrinsic noise of your system by shorting the inputs, then measure the resistor...

Hi Danish, Sorry - but I don't see that happening on my end. Do you still have our PHI connected while you are doing this test? Have you tried the same thing with our GUI? Here is what I have with...

Muhammad, 1. You're correct the state of SCLK shouldn't matter prior to the /SYNC going low. The device is looking for the falling edge of SCLK for the transition. In that case, CPOL=0 and CPHA=1...

Hello Ken, We are not able to screen DACs for a specific THD. There is no internal FIFO, and even if there was, the DC mode would not produce as good a sine wave as the sine function built into the...

Hugh, The drift specs are independent of the resolution of the DAC (either 16 bits or 20 bits). Offset and gain error and their drifts are given in units of ppm of FSR, which shouldn't be affected by...
