Part Number: LMP2234 I have a customer designing with the LMP2234. They are interested in measuring the input bias current for the part. Do we have any recommendations?
In addition, they are interested in additional ESD protection on the amplifier inputs…
Other Parts Discussed in Thread: ADS1115 , LMP2234 Hello folks,
I'm working in a design with low (uV) analog signals that must be converted to digital. I have already designed the AFE which raise the signal to 100mV - 1V orders of magnitude. After the…
Emil,
I'll just throw out a few comments to start out. If the internal reference is being used, the unused REFP and REFN can be left floating. However, the LMP2234 isn't able to drive much capacitive load. I don't know if LMP2234 can drive that much…
I calculated ADC resolution from the error bands of the settling time and not settling time itself. A precision of 0.0015% represents 1/0.000015=66,666 number of bits, which means 0.0015% of the full scale correlates with ~1 LSB of 16-bit converter (2…
Hi Herman,
Thank you for your prompt reply. Using TINA TI v9, I found a basic design utilizing the TLV379 having the spice model. We have run circuit design simulations already. The results were as expected. This morning I got a nice email from Gustaf…
Hi Nestor,
Usually, chopper op amp datasheet indicate when that is the case. I reviewed the details of the datasheet for the LMP2231/LMP2232 and LMP2234, and there is nothing in the specifications that would indicate that it is a chopper design.

Hello Yonatan,
I am assuming the 80uA is for all four amplifiers (20uA max per amplifier) in a "PW' (TSSOP-14) package:
GPN
VosRoomMax (mV)
IsMaxCh (mA)
GbwTyp (MHz)

Other Parts Discussed in Thread: LMP2234 Hello guys,
I'm designing an analog circuit where I have only a single ended power supply but need to have symmetrical power for some Op. Amps. (LMP2234). To do so, I'm using a voltage reference of +1.25V as…
