40 / 59 page ![]() 8.2 Channel sensitivity Unless otherwise stated: Tamb = 25 °C, typical supply (VDD) voltage = 1.8 V, and EXTIME = 50 ms. ST performs a light calibration of every part in production, with individual adjustment of counts into the product memory. A calibration factor is stored in the VD6283 OTP memory and calibrated data can be retrieved through the software driver. Table 17. Clear channel Parameter Conditions Min. Typ. Max.
