Q:
I have used the AD7626 in previous designs and I am considering it for a higher frequency measurement design - is there performance for the AD7626 with input frequencies > 1 MHz and can you recommend…
The selection of a filter approximation can be determined by considering a frequency and time response trade-off. A Chebyshev LPF amplitude response has higher stopband attenuation to Butterworth or Bessel…
A passive RC circuit has a real pole or zero only, and its pole or zero is on the real axis of the complex s-plane. Using active feedback shifts a real pole from the real-axis to two points, one between…
Q:
I am implementing gain and single ended to differential conversion at the ADC driver stage in my signal chain. For my circuit, I have selected the ADA4945-1. Is there a way to evaluate different diff…
Q:
For the output drive signal chain based around a precision DAC, what is the best way to simulate or calculate the total output signal chain error?
A:
The precision DAC Error Budget Calculator…
Q:
Will noise performance improve if I reduce filter bandwidth?
A:
Noise performance will improve for higher gain settings (i.e. 8 and 16).
However, a lower filter bandwidth will reduce the highest…
Q:
How can I quickly check if there is a difference between using a fully differential amplifier vs two unity gain buffers as the ADC input drive circuit for the LTC2387-18?
A:
The Precision ADC…
