GX08200 Replaces ADC08200 in UAVs

Various types of sensors in UAVs, such as accelerometers, gyroscopes, magnetometers, barometers and optical flow sensors, generate a large number of analog signals. The analog-to-digital converter therein mainly converts these analog signals into digital signals so that the UAV‘s flight control system can process and analyze them. Examples include image transmission and measurement of angular velocity.

The sampling speed and resolution of the analog-to-digital converter directly affect the response speed and measurement accuracy of the UAV to environmental changes. An analog-to-digital converter with a high sampling speed can quickly capture changes in sensors, enabling the UAV to respond quickly to unexpected situations, such as avoiding obstacles.

The GX08200 offers high-performance, low-power performance, which contributes to longer flight times for drones that rely on battery power. Driven by an external input clock, the chip can realize up to 1GSPS of 8 bits data conversion on a single channel, and contains a reference voltage source, a serial SPI control interface, and a parallel LVDS/RSDS output clock and data inside the chip. It can provide effective technical support for stable flight, precise control and efficient data transmission of UAV.
