Please teach me Addr(Hex)0x15 register of AD9231.
It will be decided 'drive strength' by this register setting.
What kind of units stripes ?
Why not 'A' notation?
Thank you for your interest in the AD9231. “Stripes” refers to the quantity of transistor stacks or "stripes" that are invoked for a given drive strength setting. More “stripes” means that more drivers are driving in parallel and thus result in a greater drive strength.
Because the AD9231 outputs are CMOS, they are often used for driving capacitive loads. Consequently, rise and fall times will change with the number of "stripes", but the steady state output current will be very low when driving a capacitive load, so units if Amps would not be as meaningful.
The main message is that more "stripes" means more drive capability.
The Output Mode (Register 0x14) and Output_Adjust (Register 0x15) registers are used to select the output drive strength, i.e. how many “stripes” are invoked. Please refer to the explanation here https://ez.analog.com/message/168179#168179 for more information. The AD9251 is the 14bit version of the AD9231.
Please let me know if you need more information.
