Hi Nithin,
We haven't heard from you in a while. We hope the issue was resolved. I am going to close thing thread now, please reply to reopen if you have any additional questions / information.
Part Number: OPA189 Other Parts Discussed in Thread: ADS1256 , , OPA2189 , OPA350 , OPA192 , OPA2192 , OPA320 , REF7025 , TMUX1108 Hello, I was redirected here from the Data converters forum for help with building a calibration board for a handheld instrument…
Part Number: DAC82001 Other Parts Discussed in Thread: OPA189 , Tool/software: Hi
The customer's circuit reference datasheet uses OPA189 buffer;
During testing, OPA189 output was fixed at REF voltage 2.5V;
Customer added a resistor 6M Ω to the VOUTA…
Part Number: OPA189 Other Parts Discussed in Thread: TINA-TI Hi,
We are considering the OPA189 for a MEMS based accelerometer. In simulation the SPICE model seems to have an aversion to asymmetrical power supplies. I would like to run it at +20,-5 V. …
Part Number: OPA189 Other Parts Discussed in Thread: TINA-TI , INA149 , LMP8480 , OPA388
I am working on a design for a high-side current monitoring circuit, using an OPA189. A very simplified schematic is shown below. I have simulated this simplified schematic…
Part Number: TLV3801 Other Parts Discussed in Thread: ADS8344 , OPA4277 , DS25CP152 , OPA189
Tool/software:
Hello, We have a fabricated circuit with TLV3801, DS25CP152, OPA189, OPA4277 and ADS8344 (see Figure 1.). TLV3801 (Figure 2.) is being used in a non…
Part Number: OPA189 Hi,
In the OPA189 datasheet there is no plot for the input current noise spectral density. I would like to know how the input current noise spectral density is vs. frequency and if there is some noise peaking around the chopping frequency…
Xueliang,
Even if your external representation of the internal OPA189 output impedance is perfect, you may NOT expect the same behaviour with the composite configuration because in the later case any signal undergoes double delay and additional phase…
Part Number: OPA189 Hi Team,
I'd like to know the Vf value of internal diode of OPA189 to design external input protection circuit. because an external protection should be work faster than internal circuit. And if you have official document of detailed…
