Looking at the AD7667 datasheet, I have troubles understanding Figure 45. Using the AD7667 in 16-Bit Bipolar and/or Wider Input Ranges.
Why the op amp can convert ±10V to 0-2.5V. Should U2 connect the analog input signal to R2 and R3? But the…
I am now using an AD7667 conversion chip, and I use the internal reference voltage, the parallel model, but my output has been FF7F, through inspection , I found that the internal reference voltage on the pin of REF is about 0.3V, this means…
Apologies that the ADC you are using is not in the tool. The AD7667 datasheet gives a recommendation for the RC filter and a suitable driver. See Figure 26 and pages 18-19.
DO you have 16bit precision ADC with master SPI so it can generate clock pulses on its own. Like AD7667. But AD7667 has too many pins.
Is there a product like AD7685 that has SPI master feature? With AD7685, so I don't have to use additional FPGA…
AD7641 for next upgrade.
The AD7767 has a feature to make the part as the master where it can provide serial data clock and SYNC signal. The AD7667/AD7671 family has this feature you may check on these parts on the ADI site (http://www.analog.com/media/en/technical-documentation…
