LMP92001 + Non Volatile Registers

Other Parts Discussed in Thread: LMP92001

Hello everybody.

This is my first post in the forum and I would like to ask a question related with the data converter LMP92001. I would like to use this IC in my new design but I found one problem. When I switch off the power supply, it loses the value loaded in all registers and you have to load again all the values when you switch on the system. I was reading the datasheet and I think that this IC has no the possibility of NON Volatile regesters. Is this truth right? Then I would like to find an equivalent IC which has NON VOLATILE registers.

Thank you very much for your help.

B.R.

    Hi Enrique,

    You are correct, this device memory is volatile. I am not aware of any equivalent device with EEPROM, in our portfolio.

    Could you describe what functionality you need in your design, maybe I can suggest something suitable for you?

    Sincerely,

    tom

    Hello Mr. Domanski

    First of all thank you very much for your reply.

    I would like to use this device to monotorize several power supplies input voltages (at least 16) and to provide several output voltages (at least 12) for some amplifiers. We want to program this device with a uC locates in other PCB board. Then this PCB board is disconnected and this IC should hold on the values of the registers to provide the output voltage again. And this IC should work for itself when the power supply is switched.

    Thank you very much.

    B.R.

    Hi Enrique,

    That is a lot of analog I/O... :)

    We do not have anything that would meet your needs, in the single package, and with non-volatile memory.

    How about splitting the problem between 3 ICs: uC with non-volatile memory, multi-channel ADC, multi-channel DAC? 

    Sincerely,
