LM6132: Transimpedance AC coupled

Duncan Yang

Part Number: LM6132

I am currently looking at transimpedance amplifiers, and I am trying to make a circuit that blocks any DC from being amplified in the amplifier itself:

How does one determine (Vout / Id) using Rg and Rf?

Hi Duncan,
C2 already takes care of blocking DC signal (at DC, C2 is open). The gain (Vout/Id) of your transimpedance amplifier is Rf . For more information on how to build a transimpedance amplifier please refer to our cookbook circuit www.ti.com/.../sboa268.pdf

I hope this helps!
