DAC60501: DAC that latches data on the rising edge of the clock

Part Number: DAC60501
Other Parts Discussed in Thread: DAC8830, DAC82001

Tool/software:

Dear Technical Supoort Team,

I'm looking into DAC that latches data on the rising edge of the clock.

DAC that latches data on the rising edge of the clock.

DAC60501 seems to be good, however this DAC that latches data on the falling edge of the clock.

Do you have any other reccomned latest DAC with latch data on the rising edge of the clock?

DAC8830/31 seems to latch the data with rising edge of the clock, but old device(BB).

Best Regards,

ttd

    Hi Ishii-san,

    Good to hear from you again (we met in the TIPL training).  We do not have many newer devices that leverage the rising edge of clock.  Most of our latest portfolio uses the falling edge.  The DAC8830 is an example.  Do you have any requirements beyond the clock edge? Resolution, voltage, channel count? 

    There are sum very, very low cost inverters that could be used on clock as well, which would open many devices to be selected.

    Thanks,

    Paul Frost

    Hi Paul-san,

    Good see you again and  thank you for your supprot on E2E.

    I'm looking for a replacement for the MAX5441. 

    Resolution: 16bit

    Voltage: 0-5V

    Channel count: 1ch

    →Does it mean such as LVC family with inverter for DAC clock ?

    Hi Paul-san,

    MAX5441 seems to be unbuffered voltage DAC.

    Additionally, I am looking for a DAC with the same data format as the MAX5441.

    I currently apply 2.5V to the REF pin for a 2.5V full scale (if the DAC's output voltage differs, I adjust the voltage with a subsequent OP-AMP).

    DAC82001 seems to match the spec except for falling clk for data latch.

    Best Regards,

    The DAC82001 is an excellent choice as well, though it does features a register addressing scheme.  This means that the SPI commands are 24bits wide vs the 16bits of the MAX device.
