Can I use two in parallel LM10010 as a 8 bits DA converter feedback?

Hello David,

LM10010 is a fixed 6bit current DAC.

LM10011 can be used as a 4bit current DAC.

Do you have a schematic which you can share? How do you plan to connect the VID digital inputs with the DSP?

Regards,

Sourav

Dear Sourav,

Thanks for your correction.

Yes LM10011 is 4/6 bits DAC.

My project is simple just conversion 8bits signal from FPGB

as a feedback voltage to control a flyback adapter output voltage.

My plan is using one LM10011 for bti0 to bit3 output another LM10011

for bit4 to bit7.

Both IDCA_out will connect to the same FB of TL431 ref pin.

regards,

David

Hello David,

The design looks right to me.

The LM10011 can be stacked in parallel. It should work fine.
