TAS6584-Q1: Relationship between current sense value and SDOUT output

Kento Adachi

Part Number: TAS6584-Q1

Tool/software:

Hello experts,

In the datasheet of TAS6584-Q1, current sense value can be output from SDOUT pin.

How SDOUT digital value and current sense value is related?

More concretly, what is the number of bits from SDOUT output?

Also, what current does all bit 1 (1111...11) indicates and what current does (000.....01) and (000....00) indicates?

Thanks,

Kento

Kento,

At 0dBFS the current reading is 30.6A.

You can derive the current value knowing that full scale is 30.6A.

Hello Gregg,

Thank you.

Sorry for my poor knowledge but how can we set bit lengths for current value digital output? (0x25 bit 0-1 register?)

Thanks,

Kento

Yes, that is for Isense data length, in TDM mode.
