DAC7562T: 5V TLL IO

Nicholas Carley

Part Number: DAC7562T
Other Parts Discussed in Thread: DAC7562

Hello,

Looking at the datasheet for the DAC7562T, it looks like the 5V TTL IO feature would allow 5V digital inputs regardless of AVDD voltage, is that correct?

The DAC7562 (non-T) IO maximum is dependent on AVDD.

Hi Nick,

The max voltage on any input pin, including the digital inputs, still needs to be below AVDD.

The 5V TTL logic sets the minimum value of VIH to 2.1V instead of 0.7*AVDD like the non T version.

non-T:

Best,
