Optional trimming of output offset voltage
WebAug 5, 2024 · The control block senses the actual V INOFF through the voltage comparators, as it is tied to output offset voltage with the following formula: V OUTOFF = A CLG. V INOFF, E2 where V OUTOFF is the output offset voltage and A CLG is amplifier’s closed-loop gain. WebThe output offset voltage may be set with a resolution of 0.39% of the voltage difference between the supply rails, ( VDD – VSS ). and where Gain = (1 st -stage gain) × (2 nd -stage gain) Vdiff is the differential input voltage …

WebMost of the Allegro™ unidirectional current sensor ICs are trimmed such that the zero ampere output is at 0.1 × VCC . The advantage of having the output voltage at 0.1 × VCC is that the output can swing slightly lower than this value before saturating, allowing the user to measure zero ampere and slightly negative current. WebA trimming circuit (100) and method of trimming is provided for offset and temperature drift trimming of an op amp or voltage reference device, having an input stage (120), on at …
WebJan 23, 2024 · With a supply voltage of V S = 3 V, the zero-g bias at the x-, y-, and z-axis outputs is 1.5 V. Considering the minimum and maximum value of this parameter, the deviation from the ideal value is 150 mV for the x- and y-axis outputs, i.e., the zero-g offset of these two axes is 150 mV.
