SBOSA93B May 2023 – January 2024 OPT4001-Q1
PRODUCTION DATA
The effective resolution of the OPT4001-Q1 is dependent on both the conversion time setting and the full-scale light range. Although the LSB resolution of the linear ADC_CODES does not change, the effective or useful resolution of the device is dependent (as per Table 6-5) on the conversion time setting and the full-scale range. In conversion times where the effective resolution is lower, the LSBs are padded with 0.
