In the ADN2830 data sheet, we know that current sink mode is the the factory default configuration. if we use this mode, Should the IBMON pins be connected to the ground in the Fig 2 and Fig3 in the datasheet ??? I think it is not necessary 'cause IBMON…
We've used ADN2830 with our CW laser control project. We parallel three ADN2830, use negtive power supply just refer to AN655.
Now we can drive the laser sucessfully, however, hugh interference signal be tested with ADN2830 each PIN,…
I have spun a board for the ADN2830 to control a JDSU laser with internal photo detector. The good news is both the cathode and anodeare isolated from the case. I'm using two in master/slave as I need about 300ma Id. Currently I have a Si rectifier for…
I have 2 questions regarding ADN2830, TEC Controller IC.
1. What is the current (or power) precision of the output power of the ADN2830? Like how precisely it can be varied (like 1microAmps/10microAmps).
2. Is it possible to control the PSET pin with…
While using ADN2830, we found the PD current from laser is lager than 2000 uA. However, the photodiode current
ADN2830 can receieved is less than 1200uA. Than, how can we use the ADN2830 to driver this laser?
Does anyone know what the current stability is of the power controller ADN2830, when operating to control constant current, rather than constant power?
Here is my application: We'd like to use an ADN2830 eval board as a current controller…
AUTOMATIC LASER SHUTDOWN
When ALS is logic high, the bias current is turned off. Correct operation of ALS can be confirmed by the fail alarm being raised when ALS is asserted.
