Part Number: OPA735 Hi,
I am using opa735 as an integrator in my application. I have used 1k Ohm input resistance and 10 uF capacitor. During testing I had given a constant voltage input voltage of - 0.1 V at its input, expecting a ramp at output but…
Other Parts Discussed in Thread: REF5025 , OPA735 , OPA187 , REF3425 hello sir,
I want to used ref5025 and OPA735 for my ADC circuit to get +2.5V and -2.5V for the voltage reference. But I found the current of the circuit is too big. the total current of…
Kavindu,
Your modified circuit actually has only 25 degrees phase margin (see below) and as Kai pointed out the minimum recommended is 45 degrees. This is because the simulation uses a typical model that does not include wafer fab process variation that…
Other Parts Discussed in Thread: OPA735 , LMC7101 Hi,
I used LMC7101 or OPA735 on a project I started a few months ago and had to put aside. For one reason or another I'm not sure which I used.
Now I have three versions of the board, and I populated…
Part Number: REF4132-Q1 Other Parts Discussed in Thread: OPA735 I have REF4132-25 presently.
My object is very strange reference voltage... 0.6V.
I'd like to divide voltage form REF4132-25, using resistors and OPA735, like this picture.
I set R1…
Other Parts Discussed in Thread: OPA735 , OPA734 , OPA333 , TINA-TI Hello,
I am following Tim Green's Operational Amplifier Stability - Part 10 of 15: Capacitor Loop Stability: Riso with Dual Feedback (acqt_092407.pdf) steps to determine best dual feedback…
Other Parts Discussed in Thread: OPA735 Hi All,
one of my power supply project am using OPA735 as unity gain inverting amplifier configuration with single supply (+12V)
my input to the inverting input is -1.27V max, and non inverting input is grounded…
Other Parts Discussed in Thread: REF5025 , OPA735 Hi,
I'm trying to find Supply current for OPA735 in the datasheet but I can't. And same for REF5025.
Am I looking in wrong place?
Regards.
Dear Tamara,
Thank you for the reply. I found the SLAU507 doc very helpful. I have tried to follow the instructions in the doc and do some simulations, but still I am finding it difficult in choosing the correct INA.
I have attached two Tina simulation…
