如下三个问题需要答复：

1、采样电阻的选取标准问题（数据手册上对采用电阻选取的描述存在前后矛盾）

1.1文档建议按如下描述选取

1.2而后面给的典型应用没有按这个规则选（此处选的是0.01，而不是0.03）

疑问：采用电阻是按什么方法选取的？？

2、电流的计算

如下图中 15.54mA/LSB 是怎么计算出来的，我计算的值是15.26mA/LSB=19.075/0.01*8

3、选用LTC2991采集电流（12V供电）的应用时，对分压电阻的选择，以及PCB layout有什么注意事项吗…

Are there any build-in error detection for the ltc2991? Say if I send the wrong memory location or if the connection is not successful through I2C, is there any way I can know that? 

(My master will be FPGA)

Hello;

I am trying to read motor arm currents using the LTC2991 IC. But I have encountered some problems as follows:

I can read the battery voltages in single-ended mode. However, I always have an offset value when reading currents in differential mode…

I am trying to read data from ltc2991 sensor through i2c. My master sends the slave address 0x90 (write), 0x91 (read) and trying to read data from memory location 0x0B. 

I have received ACKs from the slave, however, it always reads 0x00 for the data. 

I'm wondering if anyone has tried to integrate the ltc2991 to FPGA. (I am planning to read only the temperature from the sensor and my master will be Spartan 6)

I know it is communicated through I2C, however I have no experience with I2C on Verilog…

Hi,

I am studying the following voltage divider circle in LTC2991 for current measurement. I have a question for the current measurement LSB value. Appreciate any advice.

As I understand, the voltage divider will divide differential voltage in 0.01 ohm…

Hello,

I am working on the firmare for a system that uses the LTC2991 for temperature measurement.  I am adding support for detecting remote diode faults (open, short, reverse fitting).

The sense diodes are connected to V1 and V7, so I should be able to…
