Schmitt trigger

Category: Hardware
Product Number: OP07

Hey there!

I've designed a two-stage amplification circuit using the ADA4898 IC. My input signal ranges from 0.2mVp-p to 3mVp-p with a fixed frequency of 32.768 kHz, and I've applied a gain of around 10,000V/V.

Now, I'm stuck at the Schmitt trigger stage. I need to convert my output signal, which is currently a sine wave, into a square wave. However, I'm having trouble designing a proper Schmitt trigger circuit. Could you please suggest a suitable Schmitt trigger design using the OP07 or any other appropriate IC? I'm aiming for a final output of around 3Vp-p in a square wave.

I'll also share my current schematic with you to help you understand my setup better.
