In the core field of autonomous navigation for unmanned aerial vehicles, the accuracy, reliability, and stability of direction perception directly determine the success or failure of the mission. The C9000 series high-precision six axis full attitude electronic compass launched by Micro-Magic Inc pr...

Power Supply Rejection Ratio (PSRR) refers to the ratio of the input ripple voltage to the output ripple voltage, in decibels (dB), and its expression is: The significance of PSRR lies in quantifying the degree of transmission of changes in the power input to the output. For example, if the PSRR of...

One minute to read the key points of the article Application of Current Frequency Conversion Module in Inertial Sensor System   The charge-integration I/F module plays a crucial role in inertial sensor (especially capacitive MEMS inertial sensor) measurement systems, particularl...

Load regulation refers to the change in output voltage when the load current is adjusted from a minimum value to a maximum value while the input voltage remains unchanged, that is, the ability to maintain a stable output voltage when the load current changes steadily. It is a steady-state indicator....

Quick preview of article content   In the field of modern navigation technology, accuracy and reliability are crucial requirements. Both military defense systems, aerospace vehicles, ocean ships and autonomous vehicle need highly accurate navigation solutions. Among numerous navigation sensors...

The resonant frequency of the accelerometer chip is a very important performance indicator, which is related to the operating frequency range of the sensor. 1. Definition of resonant frequency The accelerometer sensor itself is also a mechanical structure, so it also has a natural frequency. As show...

Quickly browse the article in one minute Fiber optic gyroscope IMU (FOG IMU) and MEMS IMU have significant differences in accuracy, environmental adaptability, reliability, and other aspects due to differences in technical principles.

LDOs regulate their output voltage to ensure stable operation under varying load current demands. However, when the load current exceeds the designed range, such as in a short circuit or overload, the excessive current can cause chip overheating or even damage. To address this, overcurrent protectio...

The 3D electronic compass is the core sensor component for achieving spatial orientation and attitude perception in modern AR/VR systems, and its technology is based on multi-sensor fusion for complex systems. This device can measure the absolute direction of the equipment in three-dimensional space...

When we design the peripheral circuit of the IIC interface, we usually use the topology diagram with pull-up resistor shown in Figure 1, and its internal structure is the open-drain output shown in Figure 2. The open-drain output level is controlled by an external pull-up and internal logic, allow...

In the field of magnetic sensing technology, three-axis Hall sensors are sparking a precision revolution. This type of sensor achieves true three-dimensional spatial magnetic vector measurement by simultaneously detecting the magnetic field strength in the X, Y, and Z axes, completely breaking throu...
