DAC39J84: Temperature coefficients of DC electrical characteristics?

Eric Chandler

Part Number: DAC39J84

TI Representative,

Your Revision A datasheet for the DAC39J84 series parts notes that the temperature coefficients of the DC electrical characteristics were deleted. We are particularly interested in any information related to the temperature sensitivity of the DAC output currents, as we perform additional conditioning and amplification downstream, and our device is expected to operate over extended temperature ranges. The drift of the output currents with respect to device temperature is a key design parameter.

Thank you, and best regards,

Eric

Hi Eric,

Let me check with the team and just to clarify you'd like to know the coefficients right?

Miguel, that is the information we are after. However, that table is illegibly small, I'm unable to make out the numbers within the columns. Also, it appears it's reported in some multiplier factor in ppm/C. Is there a base value in uA/C we should be referencing against?

let me try another way of uploading. let me know if that helps. I've checked other devices from the same family and that is all we provide for temperature coefficients.

Thank you, Miguel. I will check with our EE team and see if this information is sufficient.
