Re: Why does the gyro need the ADC?

the full scale output of the gyro matches the full scale input range of the ADC: 0 to 5V.

Darlingtons have very high gain. Depending on where you centered the bias you would greatly expand a small portion of the gyros output, and cause the rest of its signal to be over or under the range of the ADC.

If you want a more sensitive gyro there are different versions available.
