The AD2S83IPZ is a variable resolution, Resolver-to-digital Converter allows users to select their own resolution and dynamic performance with external components. The AD2S83 converts resolver format input signals into a parallel natural binary digital word using a ratiometric tracking conversion method. This ensures high noise immunity and tolerance of long leads allowing the converter to be located remote from the resolver. A precision analog velocity signal with a typical linearity of ±0.1% and reversion error less than ±0.3% is generated by the AD2S83. The provision of this signal removes the need for mechanical tachogenerators used in servo systems to provide loop stabilization and speed control.
