A $10$ - bit $\text{ADC}$ with a full scale output voltage of $10.24 \mathrm{~V}$ is designed to have $\mathrm{a} \pm \mathrm{LSB} / 2$ accuracy. If the $\mathrm{ADC}$ is calibrated at $25^{\circ} \mathrm{C}$ and the operating temperature ranges from $0^{\circ} \mathrm{C}$ to $50^{\circ} \mathrm{C}$, then the maximum net temperature coefficient of the $\mathrm{ADC}$ should not exceed
- $\pm 200 \; \mu \; \mathrm{V} /{ }^{\circ} \mathrm{C}$
- $\pm 400 \; \mu \; \mathrm{V} /{ }^{\circ} \mathrm{C}$
- $\pm 600 \; \mu \; \mathrm{V} /{ }^{\circ} \mathrm{C}$
- $\pm 800 \; \mu \; \mathrm{V} /{ }^{\circ} \mathrm{C}$
