BQ76PL455A-Q1: BQ76PL455 Calibration question

BING CAI
Prodigy 40 points
Part Number: BQ76PL455A-Q1

HI  All,

   May I know if BQ76PL455 has  calibrated the Bandgap in whole temperature range or just in some special temperature points in TI factory. If it isn't calibrated in while temperature , can it guarantee the accuracy in whole temperature range or we must calibrate by ourselves(my understanding is calibrate the gain and offset as datasheet mentioned ).

Thanks!

    Hi User,

    The device specification is [-40C to 105C]. Hence the BANDGap is also characterized to this limits. If you are referring to the ADC, the total error from all internal sources(Vmodule_err105) is specified and guaranteed  from [-40C to 105C].
