The AD7616 and AD7616-P have similar functionality, with a few key differences.
- The AD7616 has both serial and parallel digital interfaces
- The AD7616-P has a parallel only digital interface
- The AD7616-P has relaxed timing requirements on read & write setup and hold times
- In hardware control mode, more features are unlocked when using the serial interface (AD7616 only). In parallel interface mode (AD7616 and AD7616-P), some dual function control pins are used by the digital interface so may not be used for hardware control.
