Ed,
There are many ways to do this, it depends a bit on what kind of output you want. There is the DDC112 that will measure photodiode current by integrating the charge over a sample period, then converting that to a digital output with an integrated…
Wei,
It should not matter which input I1, or I2, you decide to use as the reference input and current input with the understanding the LOG114 V LOGOUT output voltage depends on which current is in the numerator and denominator of the equation. Connected…
Hi Enrico,
The LOG114 is a solid performer when it is applied in a well designed electrical and thermal environment. My experience has been that when a user has had difficulties obtaining the expected performance the source of the issue has been traced…
Hi Lev,
Thank you for your questions regarding the LOG114...
The thermal pad must be connected to V- as per the data sheet.
The LOG114 EVM was designed for single supply operation, therefore V- in the case of the LOG114 EVM is ground. As far as the User…
