Part Number: OPA2735 Hi,
I'm having some issues with an amplifier circuit which was designed using OPA2735. The output tend to have some oscillations and I'm trying to figure out if it is from the following part of the circuit.
Appreciate if…
Kavindu,
Most of the analog IC's are designed for IQ with positive TC (increasing IQ with temperature) in order to keep the GBW constant - see below - but the change should not be more than 30% (PTAT).
Therefore, the tremendous variation in IQ…
Mariano,
Since op amps are meant to be used in close-loop configuration, you shouldn't have to warry about differential input impedance but only about common-mode input impedance - OPA2188 common-mode input impedance is around 6 Tera-ohm (6*10 12 )…
Hi Miao,
The user needs to specify the model file for OPAx735. This can be done in simulation settings. An example would be the setting in the OPA2735 downloaded from ti.com:
However, it'll work if you just specify the C:\cds_spb_home\cdssetup\pspTILibDir…
Hello,
Thanks for posting the schematic. Here are a few things I noticed:
DOUT and DIN are connected to the same net (SIMO0). Please separate.
The net BIAS should also be connected to RLDINV. R14 || C41 form the feedback path for the internal RLD amplifier…
Other Parts Discussed in Thread: LMP8358 , OPA2735 Hi all!
We are using LMP8358 as amplifier for pressure sensor , meanwhile, 50Hz oscillation or interference is observed at the output of amplifier. Short introduction of the application and test procedure…
Other Parts Discussed in Thread: OPA2735 , REF5050 , XTR111 , INA330 , LP2989 Hello,
I am using LP2989AIM-5.0 for powering up a REF5050, 2x OPA2735, one INA330 and one XTR111.
All of these IC's require decoupling caps, and since this design is intended to…
