ADC12DJ2700: Using INB+/- in single-channel mode

Part Number: ADC12DJ2700

Hello,

My customer has a question about ADC12DJ2700.

[Background]

I understood that TI recommend using INA+/- in single-channel mode.

However they want to use both INA+/- and INB+/- in single-channel mode.

It is described as follows in the D/S P.38.

<D/S>

  Using INB± results in degraded performance unless custom trim routines are used to optimize performance for INB+/- in each device.

[Q]

Please tell me the custom trim routines and the custom trim registers to optimize performance for INB+/-.

Best Regards,

Hiroshi Katsunaga
