Part Number: OPA2132 Other Parts Discussed in Thread: OPA132 , Can you explain to me why with this type of schema, programmable via the ADG441 a gain of 1 or a gain of -1. We need to change the OPA2132U IC92 after a few months of use due to off-specification…
Part Number: OPA2132 Other Parts Discussed in Thread: TINA-TI , , OPA132 Tool/software: TINA-TI or Spice Models Hi
I have multiple convergence problems in TINA TI related to the OPA2132 model from TI.
I reports convergence problems in DE, DC
I am trying…
Other Parts Discussed in Thread: OPA2132 , OPA132 I am using an OPA2132 for an input on a differential signal. I want to use 100K input and feedback resistors (unity gain). Can I use 100K resistors with this device? All of the application literature shows…
Other Parts Discussed in Thread: OPA140 , OPA132 Hi,
I'm trying a Analog Signal Filtering with OPA140 but ı think ı have a problem with OPA140 spice model. Becasue ı tried but simulation doesn't start. LTSpice try Damped-Psuedo Analysis and after this analysis…
Other Parts Discussed in Thread: OPA132 , OPA354 , OPA381 , OPA380 Hello I am designing a photo-detector to measure the frequency of a 780nm laser and I would like your expert feedback on my circuit so far. The purpose of the device is to provide a feedback…
Other Parts Discussed in Thread: OPA132 , ADS8519 The ADS8519 datasheet calls for using an OPA132 op-amp in an inverting configuration to provide a low-impedance source for the ADS8519. Could anyone explain to me why you would utilize an inverting config…
Shaun,
A comparison of the parts mentioned previously (OPA132, TLE2071 and OPA141) shows that the OPA132 has the best offset voltage (Vos) and open loop gain (Aol). A larger open loop gain will allow for more correction in gain error. The OPA141 has…
Ok, thanks for your answers. I will try it with the OPA132. As I'm not in love with the THS3201, I will abandon it. I just used it, because it has been recommended for a similar application...
regards
Timo
Ken,
There are several op amps in our portfolio with similar specifications to OPA111. The closes would be probably OPA124 but you may also consider several other amplifiers like OPA121, OPA170, OPA171, OPA132 as well as some of our bipolar input op amps…
Samer,
The OPA37 is not unity-gain stable and thus cannot be used as an integrator. C8 provides a low impedance at high frequency and effectively puts the op amp in unity gain which can cause the op amp to oscillate.
OPA132 or OPA140 are possible replacements…
