7.9 Analog Sin/Cos Outputs with External Interpolator
By connecting C1 to VDD, the AS5030 provides analog Sine and Cosine outputs (Sin, Cos) of the Hall array front-end for test purposes. These
outputs allow the user to perform the angle calculation by an external ADC + μC, e.g. to compute the angle with a high resolution.
In addition, the inverted Sine and Cosine signals (Sinn, Cosn; see dotted lines) are available for differential signal transmission.
The input resistance of the receiving amplifier or ADC should be greater than 100k Ω . The signal lines should be kept as short as possible, longer
lines should be shielded in order to achieve best noise performance.
The SIN / COS / SINn / COSn signals are amplitude controlled to ~1.3Vp (differential) by the internal AGC controller. The DC bias voltage is
2.25V.
If the SIN(n)- and COS(n)- outputs cannot be sampled simultaneously, it is recommended to disable the automatic gain control as the signal
amplitudes may be changing between two readings of the external ADC. This may lead to less accurate results.
