Hi, I am attempting to design an analog input circuitry based on the AD7768-4. The application calls for a single-ended, AC-coupled input, with a range of +/- 8V. Max frequency is ~100kHz.
I am looking for suggestions/reference design for this particular application, specifically suggestions as to what front-end amplifier is suitable. I am also open to suggestions to use ADC chips other than the AD7768-4.
The end product is a portable vibration data logger, interfacing with IEPE vibration transducers. Any suggestions greatly appreciated.
