With reference to the FV-1 Dev Board schematic and tantalum capacitors C15, C31:
1. Can these capacitors be replaced with film capacitors? I.e. is there anything that specifically requires them to be tantalum dielectric?
2. Can the value be reduced to 0.47uF? Given and input impedance of between 80k and 120k, this would yield a -3dB point of 2.82Hz to 4.2Hz which is more than adequate for my design
Hardware questions and issues with the FV-1
