TAS5760M Internal Resistor Variation of Pull-up and Pull-down

Sadanori Kato

Other Parts Discussed in Thread: TAS5760M

Hi,

We would like to know the internal resistor variation of pull-up and pull-down about TAS5760M.
The weak pull-up/down are described on page 5 to 6 of TAS5760M data sheet.
However, the resistor value is not described.
Could you please tell us the resistor values(minimum, typical and maximum)?
In addition, could you please also tell us regarding the current consumption of these pins?

Best Regards,
Kato

Hi, Kato-san,

Sorry, we are a little bit busy right now. I have asked my colleague to get back with you later this week.

Hi Don-san,

We believe this issue as below.
Is our understanding correct?

Since the input logic current level is +/-15uA max, the resistor value of the weak pull-up/down is >= 242kohm(3.63V/15uA).

Kato-san,

That's correct per our discussion.
