Part Number: OPA189 I need help understanding an odd signal I'm encountering while using two OPA189s. A simplified design is below.
DAC_1 is held constant at 2.5V. Since U1:IN+ is at 2.5V then U1:IN+ is also 2.5V and V_SHIFT, R1_s and R1_f are such…

Part Number: OPA189 Hello,
I have a question about following circuit which i have attached an image of the schematic and the bode plots of CLTF and Loop gain of the circuit. It would be really helpful to get suggestions on the stability of the circuit…
Part Number: OPA189 HI Sir
I want to confirm whether the original factory has the recommended gain and magnification for OPA189. In addition to the decrease in bandwidth, are there other shortcomings in the revenue value of competition?
