    Marie Tupaj Marie Tupaj
    Hi, I have an LMP91000 evaluation board connected to an ADC161S626 and SPIO-4 board. I have two questions. 1. I need to configure the jumper cables, J_VDD and J_MENB on the LMP91000SDEVAL board and the jumpers VREF_SELECT, VIO_SELECT, and VA_SELECT on the ADC161S626BEB board. How and where do I do...

    Hi, I am in need to identify which pins specifically are the SCL, SDA, and MENB on your LMP91000 board. Our group cannot read this from the users guide (or the board) and this is not listed in the data sheet. We are looking to connect this board with another I2C interface board. Can someone from...

  • Forum Post: LMP91000 -- has anybody used this chip with a 4-terminal eletrochemical cell?

    RICHARD FLETCHER RICHARD FLETCHER
    Hello, The LMP91000 is a nice chip (and even has internal temp sensor which is very handy for EC cells) but it's designed for 3-terminal EC cells. However, our application requires more precise measurements and we are trying to use the new 4-terminal EC gas sensors. The 4th terminal is an auxiliary...

    Roger Chen Roger Chen
    Hi all, I was going to follow http://www.ti.com/lit/an/snaa138b/snaa138b.pdf on connecting the evalboard to the MSP430, before I realized that my board was 100 pins. There are equivalent pins for P2.6, DVSS1, P6.0 on my board, but instead of UCB0SCL and UCB0SDA, there is UCB1SCL and UCB1SDA on my board...
