What is logic level needed on PWUP pin 19 to enable the ADA4961? I am operating at 3.3V, low performance (PM= Low).
The logic levels for the SPI bus and ATTEN controls are defined VHIGH= 1.4V min. Does this include the PWUP pin as well?
Yes, the same logic levels apply to PWUP, as listed under "Digital Logic Specifications" at the bottom of pg 3 in the datasheet, Table 1.
