Can we use a zero-drift (chopper stabilized) amplifier like LTC1150 or ADA4523-1 as IOUT amplifier? What should we look out for if we are to use such amplifier?

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…

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…

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…

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…

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…
