Hello Luciano,
I have looked at the documentation and it looks like this evaluation module was not designed to configure to a single supply non inverting op amp. For a pH probe, you will need the high input impedance of IN+ because of the high impedance…
Hello Andrew,
Will look into the differences between LMH730316 & LMH730216 .
In regards to your question about instrumentation amp board, the DUAL-DIYAMP-EVM features a two amp instrumentation configuration & a difference amp configuration that you…
Hi Franziskus,
We don't have a specific EVM for that package. We recommend that the customer evaluate a different package option like SOIC on the OPAMPEVM or DIYAMP-EVM. The part will behave electrically the same and it will be much easier to test…
Thomas, I did some measurements on the DUAL-DIYAMP-EVM board. First with a gain of 1. Result: almost perfect linearity. Next I changed to a gain of 8.3333. I did two measurements. With the difficulty of stepping a 0...80mV input voltage I get also very…
Hi Vasu,
The DUAL-DIYAMP-EVM has a 2 op amp instrumentation amplifier circuit configuration that can be used with the TLV9002 (dual channel version of the TLV9004).
Some practical limitations would be related to the error sources of the amplifier…
Hello kirk s,
Given a +/-12V supply, the TL084 has the following linear operating region according to the recommended operating conditions table:
Input Common-mode (min/max):
-8V<Vcm<8V
Output Swing (10kohm load, minimum):
-9V<Vom<9V
While…
Hello Art,
Thank you very much for your reply.
I will use TI DIYAMP-SOIC-EVM evaluation boards.
The user's guide SBOU162A.pdf page 9 and page 10 mentions schematics for Sallen key filter and Non inverting amp as below.
Can we use this configuration…
Part Number: OPA189 Other Parts Discussed in Thread: LM7705 Hello together,
I would like to measure the Input Offset Voltage of the OPA189:
The OPA189 has a typical Input Offset Voltage of ±0.4 μV and max. ±3 μV.
I have a HP3458A Multimeter, which…
The INA241 has high bandwidth and passes high-frequency noise. An output capacitor can reduce visible output noise. Large capacitors also attenuate fast current transients. Use an RC filter instead of only a capacitor. Try 100 ohm and 10 nF initially…
Part Number: OPA140 Hi there
I am new at anlog electronic.
I purchased a DIYAMP -SOIC-EVM to train myself with op amps but I did not test the real circuit yet.
I started with OPA140 and my question is regarding the simulation of the circuit you…
