Part Number: INA114 Other Parts Discussed in Thread: OP27 , OPA847 Hello
I'm getting an irregular circuit error when I want to do a AC analysis. The circuit is shown below,is there any solution?
Thank you very much!
OP27 and LME49720 are two different amplifiers. OP27 is a precision and high speed amp, while LME49720 is mainly focused on audio bandwidth.
OP27 has a very low frequency 1/f corner compared to LME49720, around 10 times lower. So this looks…
take care, the NMH2415 switcher is producing lots of ripple and needs a proper ripple filter at its outputs. Your ripple filter is not adequate. You should add another 3µ3 cap to the other side of 100µH choke so that a pi filter is formed. …
Part Number: OPA4140 Other Parts Discussed in Thread: OP27 , OPA140 , OPA4227 Hi team,
The customer uses OPA4140 to design an instrumentation Amplify circuit and a voltage follower circuit.
Please check his TINA circuit in the attach.
1. In his actual circuit…
Part Number: TL084 Other Parts Discussed in Thread: TINA-TI , , TL064 , TL074 , LM324 , OP27 Hi!
I am trying to build a transistor curve tracer but at some settings I get stubborn oscillations that I really can't get rid of.
I think that HF-oscillations…
Below please find couple of approaches you may take to gain up the voltage coming from the trans-impedance amplifier.
The first one shown in Fig 1, uses a difference amplifier to gain up the signal by G=20 while the second circuit shown in Fig…
thanks for your reply! I have a design in ti's clock architect. The design is called Design 5 LMX2492. It shows only one opamp, yet the opamp data sheet shows a two opamp design.
I have the TI EVK, and guess I will try the below cirucuit…
I am having X1 DC input from OP27 opamp within 5 volts, X2 is ground for denominator......Z2 from another OP27 and Z1 is ground.....Y2 is connected to o/p as feedback and Y1 is ground.....Scale factor 4 and 3,5,9,13 are NC
I remember an application where we had an unexplainable high offset voltage. Everything was tested and checked but we couldn't find the mistake. Then, suddenly the offset voltage dissapeared. What has happend? A sheet of paper was a covering…
