Analog Sin/Cos Outputs with External Interpolator
By connecting C1 to V
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 Sinus 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 100kΩ. The signal lines should be kept
as short as possible, longer lines should be shielded in order to achieve best noise performance.
The SINN / COSN / SINP / COSP signals are amplitude controlled to ~1.3Vp (differential) by the internal AGC
controller. The DC bias voltage is 2.25 V.
If the SINN and COSN outputs cannot be sampled simultaneously, it is recommended to disable the automatic gain
control
lead to less accurate results.
