LP5036: Refresh Rate

Part Number: LP5036

Hi E2E,

Good day!

A customer of mine would like to know how to compute for the refresh rate of LP5036 if they will control the output individually and will not use bank function.

Best regards,

Franz

    Hi Franz,

    I think it up to customer's I2C clock frequency. Output would immediately change (around 5 us) when write the registers relates to channels. One command includes 27 bits and we have auto-increment function, so 27 + 9 * 35 = 342 bits is the total data number to refresh all outputs. For 400kHz SCL, refresh whole outputs need around 860us.
