v1.0 testing

The first prototype is assembled.
What tests do you want us to perform?

How about testing the following, both with no load and a 1uF load to simulate a piezo:

• Small signal bandwidth
• Full power bandwidth
• Slew Rate
• RMS output noise with filter
• RMS output noise without filter

Now, with 3 voltage output settings and 3 opamp bias current settings, that would be 90 distinct measurements so it might be worth picking a bias current and voltage for exhaustive testing and just do a few spot checks on other combos.

The spec sheets that piezo drive make are quite nice and could be a bit of a template: https://www.piezodrive.com/drivers/pd32-32-channel-piezo-driver/

when testing, do not use ceramic capacitors because they have very strong C=f(V)
