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?
Hi,I moved your question to its proper community RF and Microwave.Regards,Goz
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.
