Re: ad7730
Hi, I had some similar problem with AD7730. AD7730 is connected to Silabs 8051F930 and HW SPI on the uP is used. SPI lines is connected via logic gates. Between output logic gate for CLK and AD7730 is resistor 1k Ohm (I know, that this is too large value, but this value was...
Re: making resistor
In integrated circuit (e.g. such as procesor) there are active resistors for pull-down (or pull-down).
Inside out, in "active load" (for testing el. equipment) are used FET as a electronic resistor.
