Part Number: OPA2992 Other Parts Discussed in Thread: OPA928 Tool/software: I designed a charge amplifier PCB with OPA2992 for the purposes of measuring the output of a piezoelectric sensor. The schematic of the intended circuit is shown in the first…
Part Number: OPA2992 I'd like to power the opamp with +22V/-5V power supply. The OPAx992 (and similar) specify the power supply to ±20V or to 40V. In my case the input and output are in the range from -1V to about 18V (I need to use it as a follower and…
Part Number: OPA2992-Q1 Hi,
The customer wants to configure the current sensing circuit using OP AMP.
1) How do I do R1, R2, R3, R4, and Rshunt to be able to sense normal state = 20mA?
Connect Vo directly to the MCU. 2) Where should I connect V+ and V…
Part Number: OPA2992 Hi team,
When customer powers the OPA2992 with +/- 5V and try to pass a 1 MHz signal of a few volts in unity gain then they see this:
Green is the input wave; yellow the output wave.
It looks like that this distortion occur from…
Part Number: OPA2992 Other Parts Discussed in Thread: OPA2310 Hello,
the datasheet does not specify the operating supply current per channel. There is a value of 2.4mA mentioned in Feature section. I guess it is a typical value. We plan to replace another…
Hello David,
Was the issue resolved? I will go ahead and mark Jerry's response as "TI Thinks Resolved".
If the issue wasn't resolved, please let us know so we may further assist.
All the best, Carolina
Part Number: OPA2992 Do you have a THD+N vs Frequency plot you can provide for the OPA2992 device ?
Ideally I would like to see THD+N vs frequency results out to 100khz.
Thanks.
Part Number: OPA2992 Dear Specialists,
My customer is interested in OPA2992 and would like to know RTM schedule.
Would you please let us know when is.
I appreciate your great help in advance.
Best regards,
Shinichi
Dear Sima,
Thanks for the suggestions.
- Input of THS is from OPA2992. Do I need to consider the output impedance of OPA2992, which varies with the frequency, to calculate Rf and Rg values.
- Application notes suggest to choose Rf < 1k, what would…
