ADA4522-1 biasing

Category: Hardware
Product Number: ADA4522

Hi Everyone,

I was trying to implement a TIA with ADA4522. I also wanted to bias the TIA from the noninverting terminal as shown in the figure below.

I was simulating it in LTspice and I saw that the voltage was getting clipped at the load.


Can anybody kindly suggest where I went wrong?

Thanking you in advance. 

Kind regards,

    Hi  ,

    Good day. ADA4522-1 output is rail-to-tail which means that the output will be clamped when the input goes out of the input voltage range. In this example shown in the datasheet, the amplifier…
