The AD2S99APZ by Analog Devices is a programmable sinusoidal oscillator designed to provide sine wave excitation for resolvers and a wide range of AC transducers. It integrates transducer excitation, synchronous reference, and loss of signal detection functions into a compact, cost-effective package.
This oscillator offers a programmable excitation frequency, selectable to 2 kHz, 5 kHz, 10 kHz, or 20 kHz via frequency select pins. Intermediate frequencies can be achieved with an external resistor. The device also provides a synchronous reference output signal, a 3 V p-p square wave, which is phase-locked to its SIN and COS inputs. This synchronous reference output compensates for temperature and cabling dependent phase shifts, eliminating the need for external preset phase compensation circuits.
A key feature is the signal loss detection capability. The AD2S99APZ can detect if transducer secondary winding connections become disconnected from its SIN and COS inputs, indicated by the "LOS" output pin pulling high. The device is packaged in a 20-pin PLCC and operates across a temperature range of -40°C to +85°C.
Applications include excitation sources for resolvers, synchros, LVDTs, RVDTs, pressure transducers, load cells, and AC bridges.
