Part Number: LMP91000 Tool/software: Hi,
We are currently working with the LMP91000 for a glucose meter application. Using test strips, we are successfully obtaining results. Recently, we received a new batch of strips , which are counter electrode-b…
Hi Alex,
Thanks for your response. While working with the LMP91000 in 3-lead mode for uric acid and glucose measurements.:
With Negative Bias Polarity : I observe a voltage at the CE pin with respect to GND.
With Positive Bias Polarity : No measurable…
Part Number: LMP91000 Tool/software: Hiii Team,
I am going through the datasheet of LMP91000 .The functional block diagram is given below.
In page no 13 7.3 Feature Description --> 7.3.1 Potentiostat Circuitry.The below statement is given.
The core…
Part Number: LMP91000 Other Parts Discussed in Thread: LMP91002 , ASH Tool/software: Dear team,
May I know how to configure the LMP91000 bias voltage for zero bias gas sensors.
I use LMP91002 with this sensor from Alphasense.

Hari
Hi, Alex Thompson
The customer is driving the Lead Free O2 sensor by applying the LMP91000 register settings as below, but the sensor response is not working.
- VREF 3.0V - VREF DIVIDER 67% → 2.01V - VARIABLE BIAS 24% → 0.4824V - RLOAD → 100Ω…
Nikung,
For the other settings, as I've said before, start with the defaults or what I listed above, and experiment from there. What gain is desired or how to set the right output settings is going to depend on your system and what is receiving the output…
Part Number: LMP91000 Tool/software: Hi, TI expert
The customer has an inquiry regarding LMP91000. - Application: Gas detector
According to the data sheet… When using an external amplifier resistor, R(TIA) I would like to ask if 1MΩ or 2MΩ is within…
Part Number: LMP91000 Tool/software: Dear Team,
May I know the default gain of TIA and (RTIA) and the default value of Rload.
Also may I know the use of Rload.

HARI
Part Number: LMP91000 Tool/software: Hi,
As the LMP91000 permits up to 350kohm Rtia gain resistor, I was considering designing a second amplifier stage in order to reach the requirements.
The main purpose of the design is to read electrochemical sensor…
Part Number: LMP91000 Tool/software: Hi team, I can choose GAIN by using external register between C1 and C2. However ,I don't know how much of GAIN is available at this resistance value. Could you tell me more detail for TIA spec? BR, Kengo.
