Other Parts Discussed in Thread: OPT3001-Q1, , OPT3001
Hello Team,
Our customer want to know about following points between OPT4001-Q1 and OPT3001-Q1.
- Package and pin assignment compatibility
- Operating temp and voltage condition(Can both device support 3.3V -40~105C condition?)
- The difference at register map
- Other performances.
Would you provide answer for those points?
This questions is from that they considered our device but the minimum conversion time(100ms) at OPT3001-Q1 may not meet their system requirement.
Therefore they are considering to replace other device so they want to confirm about difference between OPT3001-Q1 and OPT4001-Q1.
For 1, I think there isn't any difference between both device.
For 2, I think it is also there isn't any difference.
For 3, We can use same device address for I2C but almost all of register are difference.
0x00 register seems that the only compatible register but I cannot make sure about whether we can use same software to read data.
For 4. I found following performance comparison but please let me know if there is other difference.
