The AD2S83IPZ is a monolithic sigma-delta (Σ-Δ) PWM/PPM converter specifically designed for speed feedback and servo motor control applications. It uses a differential PWM signal with a resolution of 12-bits to allow positional feedback from angular and linear transducers, as well as tachometer feedback from various motor types. This makes the AD2S83IPZ a great choice for automotive applications, such as engine controllers, as well as heating and air-conditioning systems.

The primary benefit of using this type of converter is the ability to convert a high-resolution PWM signal into a low-resolution PPM signal that can easily be read by a common microcontroller. This means that the accuracy of the feedback system is only limited by the resolution of the PWM signal generated by the transducer.

In operation, the AD2S83IPZ converts the input PWM signal into a proportional PPM signal, which is then used to calculate the speed of the motor. The output of the converter is a PPM signal representing the speed of the motor, which is then read by a microcontroller. This signal can then be used to control the speed of the motor or other elements in the system.

The AD2S83IPZ is an ideal choice for motor control applications as it features a low noise and wide dynamic range, as well as low power consumption and an integrated temperature sensor for more precise operation. The AD2S83IPZ also comes with an integrated watchdog timer, which provides extra protection against system crashes.

The AD2S83IPZ is also a great choice for applications requiring high precision feedback with good accuracy. Its differential PWM input gives it excellent noise immunity and its 12-bit resolution lets it easily handle a wide range of input signals. Additionally, the AD2S83IPZ supports a wide range of transducer types and can be used with both linear and rotary transducers.

The AD2S83IPZ is a great choice for automotive speed and position sensing applications. Its high resolution, low power consumption and integrated watchdog timer make it a great solution for automotive systems.
