I have one ad7768-4 evm and trying to disable the precharge buffer. I have two differential input right now and I cannot turn off all of the precharge buffer. May I know how I can make the setup?
Please see this document explaining how to interface to the AD7768/AD7768-4:
Interfacing the AD7768/AD7768-4 to a microcontroller
The AD7768/AD7768-4 outputs data as a master, meaning that the device continuously streams data and it is the user's task to read the data as it is output. Therefore the microcontroller that interfaces to the data output lines must be configured as…
I want to use Xilinx FPGA to control the EVAL -AD7768-4,but I don't find the schematic diagram of EVAL-AD7768-4.Could you give me the the schematic diagram of EVAL-AD7768-4?
I know it's old, but it might be of help to others reading.
Take a look at the AD8475. From the datasheet:
The AD8475 is a fully differential, attenuating amplifier with integrated precision gain resistors. It provides precision attenuation (by 0…
The formula in the datasheet is incorrect. The correct formula is:
FMAX is the maximum usable frequency.
T11 and T4 are the AD7768/AD7768-4 timing specifications (see Table 3 and Table 5 of the datasheet).
TP is the maximum propagation…

Only the AD7768-1 device has the option to program the filter coefficients, and this is most likely the filter model you are referring to. However, this model does not apply to the AD7768 or AD7768-4 devices.

There are many amplifiers suitable to drive the AD7768/AD7768-4. Choosing the most suitable amp can be a difficult task, especially when there are constraints on the system power. In order to achieve the lowest power and highest accuracy in a data acquisition…
I have to do mechanical experiment and capture 4 analogue signals.
I plan to buy evaluation board AD7768-4 and use external processor via SPI as well as directly connect to PC.
I need to understand if I may do what I want using evaluation board AD7768…
