I've built a basic circuit with a gain of 2, but am not getting the expected output (2Vp-p)
n005 = between R2 and R5, n002 = at pin "100"
Any advice on where I am going wrong will be greatly appreciated.
ADA4870 has an Input Voltage range of + 2V headroom from the supply rails. So for Vs+ = 20 V and Vs- = 0 V, the part would accept +2V to +18V input. On your application circuit, it's beyond the IVR specification of the part. It's either you provide a DC bias to your input or move your supply to negative, i.e Vs+ = +10 V ; Vs- = -10 V.
Thanks Jino, I've provided a negative supply but am still getting unexpected results.
Please connect R4 to ground. 103 to -12 V. That will do it.
