Hi Adam,
No, there isn't an EVM or demo board for the OPA551. It comes in three different packages and many users use the DDPAK version. However, if they happen to use the 8-pin SOIC package they could likely use one of the DIYAMP-EVM evaluations board…
Hello Darden,
There is the DUAL-DIYAMP-EVM which is designed for dual op amps such as the OPA2182, in an 8-pin package. Since the DIY PC board is designed for 12 different circuit configurations it is likely you will be able to use it for your OPA2182 amplifier…
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 can…
Hi Sonia,
I'm aware of one generic signal conditioning PCB that was designed to connect to J1A on all MMBx-based EVMs, but nothing specifically for the ADS1258EVM to act as a buffer between the MUXOUT and ADCIN pins. I think the intent was originally…
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 acceptable…
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. 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 and…
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…
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…
