UAV flight control system can use ADC GX7689, compatible with AD7689

The UAV flight control system needs to accomplish complex control tasks, so the microprocessor should have rich and flexible interface resources, support floating-point arithmetic, and have programmable control capability to facilitate the completion of the current system design without expanding too many components externally. In addition, there is a need for high-precision A/D sampling circuit, signal conditioning circuits, a certain level conversion of the collected voltage signals and simple low-pass filtering process, and then output PWM control signals to control the servo to complete the control task.

It is recommended to use 16-bit sampling accuracy A/D converter chip GX7689 to complete the data acquisition function, and use SPI bus to realize the data communication between the off-chip A/D chip and the processor.GXSC GX7689 replaces AD7689, and GXSC can provide related technical support and stable supply channels.
