DAC

Hi,

Can you advise please for part number , required performance -

4 DAC and 4 IDAC in one package (small footprint)

Supply 3.3V 

Logic Interface I2C 

Resolution 12bit

IDAC 1mA resolution 0-150mA

Thanks

 

  • Hen,

    Unfortunately such a device does not exist in our portfolio and personally I have not seen such a device available on in industry (though it still could exist, of course). I believe you would need to look into discrete options perhaps based on DAC7578 / DAC7678 or dual usage of DAC7573 / DAC7574.

    Hi,
    I see 8 channels can i use part of them as IDAC?
    IDAC 1mA resolution 0-150mA

    Thanks

    Hen,

    There is no integrated current output stage, but you could use 4 of the 8 channels directly for voltage outputs and 4 of the channels with external circuits to convert from voltage to current.
