Part Number: OPA375 Other Parts Discussed in Thread: TINA-TI , OPA735
Tool/software: TINA-TI or Spice Models
The above circuit is a V-I circiut, the input voltage is 0-5V and the output current is 4-20mA. The amplifier is OPA735 and the NPN bipolar transistor…
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…
and, I had not put that TI recommended op amp into my MFB tool. The OPAx734 has disable, the OPAx735 does not but both have a staggering high input voltage noise, here I dropped it into the sim using the TI RC values and the OPA735 TINA model, apparently…
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…
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 , 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…
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 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.
