Description

The AD2S99BPZ is a Programmable Sinusoidal Oscillator provides sine wave excitation for resolvers and a wide variety of ac transducers. The AD2S99 also provides a synchronous reference output signal (3Vp-p square wave) that is phase locked to its SIN and COS inputs. In an application the SIN and COS inputs are connected to the transducers secondary windings. The synchronous reference output compensates for temperature and cabling dependent phase shifts and eliminates the need for external preset phase compensation circuits. The synchronous reference output can be used as a zero crossing reference for resolver-to-digital converters such as Analog Devices AD2S80A, AD2S82A, AD2S83 and AD2S90.
Dynamic phase compensation
Programmable excitation frequency
Signal loss detection
Synthesized synchronous reference output
Loss-of-signal indicator
Integrates the transducer excitation, synchronous reference & loss of signal detection functions
ESD sensitive device. Electrostatic charges as high as 4000V readily accumulate on the human body and test equipment and can discharge without detection.
