A weak voltage analog dimming method for high precision light emitting diode (LED) current control with N-Bits analog static offset calibration (N-Bits ASOC). dynamic offset cancellation (DOC) and K-times dimming duty to voltage (KD2V) conversion is presented. The N-Bits ASOC circuit decreases the analog dimming error to VOSMAX/2N - 1 by pre-calibrating the error amplifier offset. Mor... https://herbsdailyes.shop/product-category/diagnostic-test-kits/
