Hi,

I had measure the Iout, but the result was not the same as I thought.

Can you help to check the schematic is correctly or not.

I have two LTC2757 DACs. Each has an LT1001 transimpedance amp. I'm generating a square wave with each. The square waves have 0.2V amplitude. I update the DAC values at 100 Ksps, regardless of whether there is a change needed in the output voltage. The…

Hi,

A few questions about this DAC:

1) Based on the timing characteristics of the digital interface for Vdd = 3.3V, it should be feasible to update the LTC2757 at 16.66 MHz.  However, if the output settling time specification in the datasheet is 2.1 us…

I would like to use an LT1010 output buffer:

...with the LTC2757 DAC:

The LT1007 as shown in the buffer schematic will be substituted for the LT1468 shown in the DAC schematic. My questions are:

1. Where should I connect the DAC's Rfb input? Should…

I am trying to figure out how to estimate the total output noise voltage density when I connect a LT1460 reference, LTC2757 DAC, and a LT1468 output transimpedance amplifier together. The datasheet simply lists "output voltage noise density" with no information…

Hi

If you have to build waveform generator and choose a DAC to generate ultra pure (over 100dB SFDR) ultra precision (below 5uV offset), ultra low noise (below 10nV/rsHz) 10khz sine wave what would you chose ?

My first choise is LTC1668 + composite…
