DAC60501: How to set RESOLUTION using DEVID in DAC60501

Part Number: DAC60501

Hello team,

This is sagar , I am working on DAC60501 and I have some queries regarding this IC please find below :

1) How to set resolution using DEVID reg as per datasheet ( It seems confusing )

2) What is use of RSTSEL and it is not affecting output mV even if I change the bit

3) How to send data through DAC reg( addr/cmd : 8 ), I tried by sending 0xFFF but still I am getting 0.150mV ( gain : 1 and ref.div : 1, VDD : 5V ) .

Thank you in advance!!!

    Hi,

    Thanks for writing to us.

    1. DEVID register field is read only. You can't write into these registers. For DAC60501, since its is 12 bit resolution, if you read the register bit 14 to 12 should be read as 0x20h

    2. Similarly RSTSEL is also read only bit. Depends on the variant you ordered , whether its M or Z variant this bit should be either 1 or zero.

    3. Can you please post your schematics and initialization code so that I can look at the same and suggest how to go forward?

    Hi,

    Thank you for your quick response,

    I am able to communicate with IC, I can change BUFF-GAIN and REF-DIV bits,

    1) Initially I am changing BUFF-GAIN and REF-DIV bits as per application

    2) As per sensor data, I am sending DAC_COUNTS  through I2C but I am getting 150mV at output.

    These are steps I am doing in my code.

    Hi,

    Can you please share your schematics for DAC section? And what is the power supply for DAC?

    Regards,
