DAC53001: Can dac53001 support 1.8V voltage level ?

Part Number: DAC53001

Tool/software:

Hi TIer

My customer wants to communicate at 1.8V, do we support 1.8V?

Since the VIH is recommended to be a minimum of 1.6, is the excess sufficient?

Thank you very much.

  • Hi Tony

    1.8V logic is supported. Are they expecting to run at max I2C or SPI speed? We have tested the device at max SPI & I2C speeds with a 1.62V VIH and have verified the performance. If the customer is concerned with their controller not meeting the 1.62V VIH, the device will likely still work at lower clock speeds. We just don't have the characterization data for lower VIH. 

    Best,
