Please let me consult about the LTC2757 glitch.

Even though the UPD pin is in the L state, if the value of DATA I/O is changed,
A glitch occurs at the output when changing the value of the DATA I/O to the output.
Is this normal?
(Other conditions are WR…

Q1:The RFB of the LTC2757 is 10KΩ (TYP) in the table specs, but can it be changed by setting the output voltage span?

Q2：In that case, could you tell me the reference value?

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 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,

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…
