ADS1015 sda/scl input capacitance

Dan,


Based on a previous post in the Internal Forum, can look through the IBIS model and derive the capacitance. There's a link to a Bonnie Baker article about this shown here:

www.edn.com/.../Signal-integrity-and-characteristic-impedance

From the previous internal post, they derived the SCL line to be about 1.6pF, and the SDA line to be about 4.4 pF.
